arduinostl's Introduction

ArduinoSTL

This is an implementation of a C++ standard library packaged as an Arduino library. The library supports teaching my CS-11M class by adding key C++ features into the Arduino environment.

The library is ported from uClibc++:

http://git.uclibc.org/uClibc++

With a streams implementation from Andy Brown's Arduino Library:

http://andybrown.me.uk/2011/01/15/the-standard-template-library-stl-for-avr-with-c-streams/

Using printf() and scanf()

The ArduinoSTL header file contains code to bind a serial port of your choice to the stdio primitives. This happens automatically but the user must still call Serial.begin()

#include <ArduinoSTL.h>

void setup() {
  Serial.begin(9600); 
  printf("Hello World\n");
}

Using `cin` an `cout`

When you include this header file you automatically get cin and cout based on Serial. See below for how to specify your own device. Here's an example sketch using cin and cout .

#include <ArduinoSTL.h>

using namespace std;

void setup() {
  Serial.begin(9600);
  cout << "Feed me an integers." << endl;
}

void loop() {
  int foo;
  if (cin >> foo) { 
    cout << "You fed me " << foo << endl;
  }else{
    cin.clear();
    cin.ignore();
  }
}

Changing the Serial Port

You can change what serial port that cin, cout and printf() use. You can use built-in serial ports (e.g. Serial1 on Leonardo) or you can use software serial ports that implement Stream.

Using a Built-in Port

In src/ArduinoSTL.cpp change the value of ARDUINOSTL_DEFAULT_SERIAL. Leave the other defaults uncommented.

Using a SoftwareSerial port.

Set ARDUINO_DEFAULT_SERAL to NULL. Comment out the other defaults.

Here's an example sketch that uses SofwareSerial:

#include <ArduinoSTL.h>
#include <SoftwareSerial.h>

SoftwareSerial mySerial(0, 1);

namespace std { 
  ohserialstream cout(mySerial);
  ihserialstream cin(mySerial);
}

void setup() {
  mySerial.begin(9600);
  ArduinoSTL_Serial.connect(mySerial);
}

Avoiding Instantiation of `cin` and `cout`

Comment out ARDUINOSTL_DEFAULT_CIN_COUT and nothing will be instantiated. You must comment out this flag if you intend to select a non-default serial port. There's no appreciable overhead for using printf() so you cannot currently avoid initializaing it.

Known Issues

Printing of floats and doubles using cout ignores format specifiers.

uClibc seems to be fairly complete. Strings and vectors both work, even with the limited amount of heap available to Arduino. The uClibc++ status page can be found here:

https://cxx.uclibc.org/status.html

Always use the latest Arduino IDE. This library uses the Arduino IDE Library Specification rev.2.1 with features only available on Arduino 1.6.10 and higher. The specification can be found here:

https://github.com/arduino/Arduino/wiki/Arduino-IDE-1.5:-Library-specification

License

The uClibc++ library is licensed under the LGPL. This project adopts the LGPL to be compatible with the bulk of the code that it uses. Unless otherwise noted all code is licensed under the LGPL. There's one exception:

src/serstream is licensed under the BSD license according to Andy Brown's wishes here: http://andybrown.me.uk/terms-and-conditions/

Failed compilation of code using ArduinoSTL.h and array on Arduino Uno AVR Boards 1.8.3

I have written arduino C++ code in which I used std::array quite a lot. Of course I made sure to #include<ArduinoSTL.h> and #include<array>. The compiler raises multiple compilation errors (see below) without pointing to any line of the code:

/home/salwa/Arduino/libraries/ArduinoSTL/src/del_opvs.cpp:25:53: error: 'std::size_t' has not been declared _UCXXEXPORT void operator delete[](void * ptr, std::size_t) throw(){ ^~~~~~ /home/salwa/Arduino/libraries/ArduinoSTL/src/del_ops.cpp:25:50: error: 'std::size_t' has not been declared _UCXXEXPORT void operator delete(void* ptr, std::size_t) throw(){ ^~~~~~ /home/salwa/Arduino/libraries/ArduinoSTL/src/del_opnt.cpp:25:56: error: 'nothrow_t' in namespace 'std' does not name a type _UCXXEXPORT void operator delete(void* ptr, const std::nothrow_t& ) throw() { ^~~~~~~~~ /home/salwa/Arduino/libraries/ArduinoSTL/src/new_opnt.cpp:25:37: error: declaration of 'operator new' as non-function _UCXXEXPORT void* operator new(std::size_t numBytes, const std::nothrow_t& ) throw(){ ^~~~~~ /home/salwa/Arduino/libraries/ArduinoSTL/src/new_opnt.cpp:25:37: error: 'size_t' is not a member of 'std' /home/salwa/Arduino/libraries/ArduinoSTL/src/new_opnt.cpp:25:37: note: suggested alternative: /home/salwa/Arduino/libraries/ArduinoSTL/src/new_handler.cpp:22:12: error: 'nothrow_t' in namespace 'std' does not name a type const std::nothrow_t std::nothrow = { }; ^~~~~~~~~ /home/salwa/Arduino/libraries/ArduinoSTL/src/new_handler.cpp:25:6: error: 'new_handler' in namespace 'std' does not name a type std::new_handler __new_handler; ^~~~~~~~~~~ /home/salwa/Arduino/libraries/ArduinoSTL/src/new_handler.cpp:27:1: error: '_UCXXEXPORT' does not name a type

A similar issue was opened here https://github.com/mike-matera/ArduinoSTL/issues/56, it was suggested to use #include"ArduinoSTL.h" instead of #include<ArduinoSTL.h>, I did that but it didn't work. I also tried downgrading the AVR boards manager from 1.8.3 to 1.8.2 and to 1.8.1 but that didn't seem to solve the problem.

Computer kernel/OS: 5.4.0-67-generic #75~18.04.1-Ubuntu
ArduinoIDE: 1.8.13
Tested AVR Boards manager: 1.8.1, 1.8.2, 1.8.3 (the problem persists with all these versions)

Any suggestions?

Suggestion: correct Missing info in Documentation

Hello, this is pretty simple as issues go but....

there's Mike-Matera/ArduinoSTL and Mike-matera/avr_stl

documentation for avr_stl is identical to ArduinoSTL even down to saying #include <ArduinoSTL> and not as might be expected #include <avr_stl>
There's no indication what distinuishes these two libraries. Both have similar recent commits and both are available on the Arduino applications library manager.

Maybe indicate in the documentation what differs and what the use cases are intended for.

width() non-functional (for me)

This code:
[code]
// width.cpp -- using the width method
// C++ primer 17.4, page 1080

#include <ArduinoSTL.h>
//#include <PrintStream.h>

void setup() {

Serial.begin(115200);

using std::cout;
int w = cout.width(30);
cout << "default field width = " << w << ":\n";

cout.width(5);
cout << "N" <<':';
cout.width(8);
cout << "N * N" << ":\n";

for (long i = 1; i <= 100; i *= 10)
{
    cout.width(5);
    cout << i <<':';
    cout.width(8);
    cout << i * i << ":\n";
}
// std::cin.get();

}[/code]

void loop() {}

is supposed to print right justified. It doesn't, everything on a line is jammed together.

Am I doing something wrong?

Facing problem with usase of functional

`
typedef std::function<void(uint8_t pin, uint8_t event, uint8_t count, uint16_t length)> TDebounceEventCallback;

I have a library which is using function templates like this, and i am little new with this type of code in C++. But i found that in the arduinoSTL library there is no template for function instead only for unary_function and binary_function...
Can somebody help me here how can i use function of that sort...

multiple definition of `std::nothrow'

When compiling the following sketch,

#include <ArduinoSTL.h>

void setup() {}
void loop() {}

this error is raised:

arduino-cli compile --fqbn arduino:avr:pro --warnings all --output-dir build \
    --build-property compiler.cpp.extra_flags="-pedantic"
new.cpp.o (symbol from plugin): In function `operator new(unsigned int)':

collect2: error: ld returned 1 exit status

Commenting out line 22 of src/new_handler.cpp seems to fix the issue, but this perhaps introduces other problems.

My set up:

arduino-cli Version: 0.25.1 Commit: 436f0bb9 Date: 2022-07-25T15:01:55Z
ArduinoSTL version 1.3.3

This issue can be reproduced in the Wokwi simulator.

printf blocks for a long time when serial monitor gets disconnected

To reproduce, connect an LED to pin 13 (if one isn't already), copy this file to a new sketch and upload the code to your Arduino.

Then, watch the LED blink. If you then open the serial monitor, you can see "running... " being printed periodically.

If you then close the serial monitor again, the LED blinks very slowly. Instead of 1000ms for one full on-off cycle, it takes about 6500ms. When turning the serial monitor back on, speed reverts to normal.

The same thing happens when using Arduino's built-in Serial.println like this, however the total duration only increases to about 2000ms.

Is this fixable? Can I maybe try and detect a disconnected serial stream to work around this?

Memory usage of this library

This library uses 22 % (468 or 459 bytes) of the dynamic memory (RAM). Since I have trouble with memory with one of my projects, is there a way to reduce your library's memory usage?

fails on wokwi.com due to the following

Trivial sketch won't compile using Arduino 1.8.13

This library worked mostly fine for me in Arduino 1.8.12, but in 1.8.13 the following trivial sketch won't compile. My intuition is that it's an include-order dependency issue.

#include <ArduinoSTL.h>

void setup() {
  // put your setup code here, to run once:
}

void loop() {
  // put your main code here, to run repeatedly:
}

I have tried the 1.8.5 and the IDE rc6. Am I missing something here, or has this issue resurfaced?

Will Heap Data Structure be Implemented?

I'm wondering whether implementation of std::priority_queue will be added later. I understand there is heap related functions in algorithm. Thanks.

Issues using map

Hi Mike.
I'm using your library, and everything seems to work except map.
Here's my declaration in a .h file:
std::map<int, edSession*> sessions;
and the error I get is:
this declaration has no storage class or type specifier
What is wrong, please?
I also can't see how string, map and vector get pulled into my .h file when I add:
#include <ArduinoSTL.h>
Can you please explain? I'm fairly new to Arduino/C/C++

Including <initializer_list> with library

Hi,
I'm currently working on an Arduino library and I would like to use initializer lists to make it easier to use. This is supported on Arduino-compatible boards with ARM, ARM/SAM or Xtensa architectures, but not on AVR.
I'm able to solve this problem by including your initializer_list file. I just copied it to the src folder of my own library as initializer_list.h and added the following to my library source files:

#ifdef __AVR__
#include "initializer_list.h"
#else
#include <initializer_list>
#endif

Everything works great, however, I have no idea if it's allowed to redistribute this file with my library, and if so, how to do it without infringing any copyright laws.

Thanks in advance,
Pieter

Accessing Inner pointer for std::vector

I recently installed the library hoping it would aid my implementation.

What I basically do is I try to access the inner pointer to the data held by std::vector, like in the standard std::vector implementation using vector::data() function. This gives me a ton of errors because I think this functionality is not implemented.

Later edit: What I am trying to do is copy some memory held in a regular C buffer inside of the vector:

std::vector<uint8_t> buffer(10);

// some C buffer here holding some data called let's say buf
// copy it in the vector
memcpy(buffer.data(), buf, 10 * sizeof(uint8_t))

Could this be achieved using ArduinoSTL?

Later, later edit: Just realised that the begin() function does exactly what I am looking for.

<array>?

I see that there's valarray but not array. This strikes me as strange because it seems like array would be the logical choice to use on a microcontroller for static data, which is what I want array for.

Use case: constant array of instructions to run on some given input, compatible with c++ features and avoiding using a c array.

cout should support const char arrays from flash

It should be possible to use Macro "F()" to store strings (const char*) from flash memory (PROGMEM) like Arduinio print/println does. This saves RAM.

cout << F("\r\nSystem halted!") << endl;

The Arduino library uses class __FlashStringHelper in macro F(). I have added (in "ostream")

template<class charT, class traits> _UCXXEXPORT basic_ostream<charT,traits>&
    operator<<(basic_ostream<charT,traits>& out, const __FlashStringHelper* c)

and

template<class traits> _UCXXEXPORT basic_ostream<char,traits>&
    operator<<(basic_ostream<char,traits>& out, const __FlashStringHelper* c)

With code from Arduino library file Print.cpp. Have given it a short test and it works on Arduino UNO with current IDE / eclipse.

Will try to attach patch.

Add library to PlatformIO

Can you add this library to the PlatformIO library manager?

Will not compile for Teensy 3.1/3.2

I struggled the past days to compile my project, where other libs included ArduinoSTL, even though, they did not use it. It took me some time to figure it out. The following code will not compile on PlatformIO@VSCode and does nothing but include the ArduinoSTL.h @ version 1.1.0.

https://pastebin.com/7KE4puMr

The Error is https://pastebin.com/vm51i2zQ

It looks like, C++11 keywords are not recognized, even though, everything is compiled with at least C++11, if not C++14. I tested this on ArduinoIDE too (with teensyduino-core) and had similar troubles.

Solution to my problem: Exclude ArduinoSTL from compile. But this won't fix the incompatibility of this lib with the compile for the teensy platform

Note: ArduinoSTL compiles perfectly fine on Arduino Uno/Nano though.

Problems compiling

From a minimal setup in a new project, including only:
#include <ArduinoSTL.h>

I'm getting:

... error: '::abort' has not been declared 27 | using ::abort; | ^~~~~

etc... from cstdlib and similarly for all of cmath.

Using:
Arduino IDE 1.8.13
1.8.2, 1.8.8 of Arduino SAMD, 32 bits ARM Cortex-M0+ Board (Adafruit ItsyBitsy M4)
1.6.2 Adafruit SAMD
On Windows 10

Strange thing is that it was working fine and then at some point later in the day I upgraded versions in the board manager ... tried downgrading but never got things working again.

The other thing I did earlier in the day was install Atmel Studio 7. Was able to compile after that, though.

I tried using nholthaus' version from issue 56, as the issue looked possibly similar to mine, but had no luck with it. Same result.

Thanks in advance for any help with this issue.

Client side Serial binding to cin/cout

Hi!

Saw your code comments about it, and yes its needed...

my approach was to remove the .cpp implementation

namespace std
{
  // ohserialstream cout(Serial);
  // ihserialstream cin(Serial);
}

and add this to my sketch

ohserialstream std::cout(Serial);
ihserialstream std::cin(Serial);

for me it sounds as a nice trade-off, no?

P.S. ok looking at __stdio_wrapper ...

C++11 smart pointers support

Any plans for that?

License of serstream unclear

This library suggests (through its LICENSE file) that it (exclusively) uses the LGPL license. However, Andy Brown's stream support (which I think is only the serstream file) uses a different license (the serstream file refers to http://andybrown.me.uk/terms-and-conditions/ which shows a BSD license). I'm not sure if there are other files with different licenses?

I would suggest:

Adding a note to the README about the license in use (e.g. LGPL for most files, referring to LICENSE and list files with different license
Adding the BSD license from Andy's site into the serstream file, to make it clear what license applies (this is really something that Andy should have done, but doing it here at least improves the clarity of the licensing of this library).

How does that sound?

        Serial.println("right");
      break;
      case 3: // Motor left
        digitalWrite(dc_direction_pin, 1);
        Serial.println("left");
      break;
    }
 
    Serial.println(0);
    packet_deque.pop_front();
    Serial.println(1);
  }

The serial monitor output

19:51:53.975 -> Started
19:51:54.997 -> on
19:51:54.997 -> 0

As you can see, the pop_front of the deque causes the arduino to fail in some way.

Additional Information: Arduino Uno, 9600 baud rate

Wont compile with VS Code and PlatformIO

I tried your previous STL library, that wouldnt compile, but i saw a comment saying that project was dead and to try this one instead. So I scrapped that idea and tried this one. Again I get a failure to compile.

#include "ArduinoSTL.h"
void setup()
{
}

void loop(void)

Is this project dead too or not supporting VS Code PlatformIO ?

Support for Error Handing for using with Eclipse plugin

No errors at all when using with the Arduino IDE.
However, I'm one of those who prefers to use the more expansive Eclipse IDE + plugin.
I imported the source code library with no issues, however when attempting to compile receive the error:

"C:\Users\David\Documents\Arduino\libraries\ArduinoSTL\extras\uClibc++-OriginalFiles\tests\testframework.h:32:3: error: exception handling disabled, use -fexceptions to enable

Any ideas of settings or quick fix to make this compatible?

What am I doing wrong?

Problem with %f in printf and scanf

I'm trying to use printf() and scanf() with %f format specifier, but they not work. For scanf(), the program does not wait for the serial and for printf(), it prints the float number as a "?".

Using cin and cout it works correctly, but with only 2 digits of precision.

I'm using an Arduino Nano with ATMEGA328.

Thanks!

Memory usage

Thank you for your work on this library. When I swapped out StandardCplusplus for your's, I noticed an almost 20% increase in memory requirements. Is this normal and/or expected? Seems like this will be problematic for me using one of my Uno's.

std::function not supported ??

hello
i would like first to thank you for the great work.
i would like to use the following code, but i guess the functional header doesnt have the function template:
#include

class LambdaTest {
public:

LambdaTest(std::function<void (int n)> lambda){
lambda_ptr = &lambda ;
}

void callLambda(int value) {
(*lambda_ptr)(value);
}

protected:
std::function<void (int n)> *lambda_ptr;

};

Reverse order of std::swap_range and std::iter_swap

There is an issue when compiling for a Genuino Zero.
It does not like the fact that the definition for std::iter_swap comes before std::swap_range (which uses it).
The order two functions should be swapped.

C++11 std::function support

Any plans?

So cores/teensy/new.h with its declaration of

 _UCXXEXPORT void operator delete(void* ptr) _UCXX_USE_NOEXCEPT;

Maybe it's possible to detect the Teensyduino core case via TEENSYDUINO global macro and not declare / define the delete operator?

std::string and FreeRTOS fails

Hello,
I am relatively new to Arduino and my C++ knowledge is a bit rusty so please excuse if i'm wrong with my post.
There seems to be a memory allocation problem with strings in combination with FreeRTOS. The following code works fine:

#include <Arduino_FreeRTOS.h>
#include <Controllino.h> 
#include <ArduinoSTL.h>

void StringTestTask(void *pvParameters);

void setup() {
  Serial.begin(9600);
  while(!Serial);
  std::string s("Hello World!");
  Serial.println(s.c_str());
  xTaskCreate(
    StringTestTask,
    "StringTestTask",
    512,
    NULL,
    2,
    NULL);
}

void loop() {}

void StringTestTask(void *pvParameters) {
  std::string s("Hello World!");
  Serial.println(s.c_str());

  for(;;) {}
}

I get "Hello World!" on my serial console. When I comment out the string in the setup() function like this:

#include <Arduino_FreeRTOS.h>
#include <Controllino.h> 
#include <ArduinoSTL.h>

void StringTestTask(void *pvParameters);

void setup() {
  Serial.begin(9600);
  while(!Serial);
  //std::string s("Hello World!");
  //Serial.println(s.c_str());
  xTaskCreate(
    StringTestTask,
    "StringTestTask",
    512,
    NULL,
    2,
    NULL);
}

void loop() {}

void StringTestTask(void *pvParameters) {
  std::string s("Hello World!");
  Serial.println(s.c_str());

  for(;;) {}
}

Nothing is written to the console. The rest of the library seems to work (at least the parts I have tested).
Any suggestions about this? Thank you for your help.

ArduinoSTL and Visual Micro

Hello,

I recently decided to code for the STM32s I got a couple of years ago. And indeed, I decided to use the STL... (on a Black Pill)

But, is STM32 supported ?

In Arduino IDE : it seems it is.

In Visual Studio + Visual Micro, your library is not recognized, and headers not included until "architectures" is set to "*" in file library properties. And even with this change, I immediatly ran into problems (Visual Micro only). I don't understand why... They share the same gcc.

I found nothing on the web about such an issue, and STM32duino website is down (Server quota exceeded).

Here's some code that compiles and run fine with Arduino IDE, but not Visual Micro :

#include <ArduinoSTL.h>

class Item
{
	public:
	Item(uint32_t i, std::string s): index(i), str(s) {}
	std::string str;
	uint32_t index;
};

std::vector<Item> Vector;
Item item0(5, std::string("five"));
Item item1(4, std::string("four"));
Item item2(3, std::string("three"));
Item item3(2, std::string("two"));
Item item4(1, std::string("one"));
Item item5(0, std::string("zero"));

bool compare(Item& item1, Item& item2)
{
	return item1.index < item2.index;
}

void setup()
{
	Serial.begin(9600);
	while (!Serial) ;
	Serial.print("hello\n\n");
	Vector.push_back(item0);
	Vector.push_back(item1);
	Vector.push_back(item2);
	Vector.push_back(item3);
	Vector.push_back(item4);
	Vector.push_back(item5);

for (auto& iter : Vector)
   Serial.println(iter.str.c_str());

Serial.println("\nsort :\n");

std::sort(Vector.begin(), Vector.end(), compare);

for (auto& iter : Vector)
   Serial.println(iter.str.c_str());
}

void loop()
{
}

Errors in Visual Micro ; seems to be related to std::sort()

Weird issue with Serial commands

After swapping out another library for you'rs, I noticed an issue with Serial.println() invocations. They don't seem to work outside of the setup method. And if I include Serial.println() commands with other functions contained in previously working lambdas on timed intervals, it prevents them from functioning.

Have you encountered this before?

Support for unordered_map

I noticed not all of the STL types are present, like unordered_map for example. Are these planned for the future?
