Should pins start as low when set to OUTPUT with pinMode()? Check Arduino / Wiring spec and match msp430 code if different.

Seems that Wire set to module 0 conflicts with Serial. Serial stops working if Wire.setModule(0) is called in setup. Individually they work.

Using the implementation of PLACE_IN_FRAM defined at #31, compiling against the MSP430FR2433 raises an error.

  LED = RED_LED;

  pinMode(LED, OUTPUT);

Sketch can be uploaded and run, but the variable placed in RAM can only be read, not written, so the red LED doesn't blink.

The initClocks function for MSP430s based on Basic Clock Module+ (with BC2) doesn't really initialize BCSCTL2 properly. All it does in initClocks() is:
/* SMCLK = DCO / DIVS = nMHz */ BCSCTL2 &= ~(DIVS_0); enableXtal();
In fact, that code does nothing, because DIVS_0 is 0, so ~(DIVS_0) is 0xFF, and BCSCTL2 is an 8-bit register, so bitwise-anding it with 0xFF does nothing. I think what is desired here was actually "BCSCTL2 &= ~(DIVS_3)", namely, clearing all of the DIVS bits.

By the user's guide, BCSCTL2 should start up at 0, so this shouldn't be a problem, but it would be a lot more readable to explicitly replace that with

/* SMCLK = DCO / DIVS = nMHz */ BCSCTL2 = SELM_0 | DIVM_0 | DIVS_0;

so that it's obvious exactly what the SMCLK and MCLK are being set to.

I removed enableXtal() there because it's actually called at the end of that function anyway. enableXtal takes a huge amount of time if the crystal's not present, so calling it twice has a big downside.

FRAM is an exclusive technology, but how to leverage it for large arrays?

Hi,

When I run a simple blink using sleep() or sleepSeconds() instead of delay(), the durations are not respected. I did not make a precise measure, but the factor seems to be 10x ( sleepSeconds(1) seems to lead to a 10s pause, sleep(500) seems to lead to a 5s pause ...).

I just re-installed 1.0.3 msp430 core to be sure (I will try with previous versions). Not tested on other microcontroller. Original lauchpad 32768 Hz crystal is soldered. Windows 10

Code :

void setup() {
 pinMode(P1_0,OUTPUT);
}

void loop() {
digitalWrite(P1_0,HIGH);
sleepSeconds(1);
  digitalWrite(P1_0,LOW);
sleepSeconds(1);
}

Hi,

i'm trying to use a LoraWan library (Lmic) on MSP430F5529LP, i got it to work on arduino uno without any problems, how ever on the MSP430F5529LP i'm getting some errors like:

code:67: error: expected primary-expression before '.' token

after some research i found out that the library requiers Arduino IDE version 1.6.6 or above, since it requires C99 mode to be enabled by defau, t so is it possible to enbale the C99 mode in compilation options,if so , how can i do it?

Thanks

MSP430F5529 does not have the clock divider register (FCTL2), which breaks MspFlash.cpp.

In addition, the examples in the family guide check the BUSY flag in FCTL3 before/after write and erase operations. This might be required for reliable operation. (note that the function of this flag is different in the G family).

Error message and suggested solution see:

Current GCC tool-chain for MSP430 is versioned 4.6.5 but is limited to 64 KB.

I gave a try to GCC MSP430 6.4.0.32 with options -mlarge -mcode-region=upper -mhwmult=auto.

Surprise is, variable and code sizes are significantly bigger.

• With GCC MSP430 4.6.5 for blink against MSP430G2553

Estimated Flash: 1114 bytes used (2.3% of 48128 maximum), 47014 bytes free (97.7%)
Estimated SRAM: 22 bytes used (1.0% of 2048 maximum), 2026 bytes free (99.0%)

• With GCC MSP430 6.4.0.32 for blink against MSP430G2553

Estimated Flash: 1936 bytes used (4.0% of 48128 maximum), 46192 bytes free (96.0%)
Estimated SRAM: 152 bytes used (7.4% of 2048 maximum), 1896 bytes free (92.6%)

This may rise issues for the MSP430G2553 but not for the MSP430F5529, MSP430FR5969, MSP430FR5994 and MSP430FR6989 with large Flash and RAM.

I haven't explored yet projects which size is larger than 64 KB.

Are there a roadmap and a release date for the support of GCC MSP430 6.4.0.32 with projects larger than 64 KB?

Thank you!

How difficult / easy would it be to add support for the MSP430G2955 on Energia?

Apart the MSP430G2553 which comes in DIP package, the MSP430G2955 is easy to solder on a TSSOP to DIP adapter. It provides more Flash and RAM.

Thank you!

It would be good if the MSP430 package indexes were available for the boards that get pre-installed in Energia, so that we can have a working example to start from. I've been totally unable to make a custom board install via the Board Manager since I'm pretty much workinng blind.

Hi, I am trying to port a library (for the ADS1258) over from an Arduino uno to a MSP430F5529 as I am running out of resources (RAM, and in a next step pins).
I am trying to get the SPI side working now and noticed that on the energia website many of the spi documentation pages still seem to reference the arduini (uno, due, mega) instead of the MSP variants. http://energia.nu/reference/spi/spi_setclockdivider/ does unfortunately not tell me how to set the spi clock I need (4 MHz) with the 25 MHz F5529.
Also, is it planned to implement the
SPI.beginTransaction(SPISettings(SPI_SPEED, xSBFIRST, SPI_MODEy));
and SPI.endTransaction functions into energia?

The file MSP-EXP430FR6989.ccxml should be MSP-EXP430FR6989LP.ccxml in the DSLite package.

The following basic sketch doesn't display anything on none of the two serial ports from the MSP430FR4311 LaunchPad.

The same sketch with the same USB cable works fine on the MSP430FR6989 LaunchPad.

All jumpers except CTS and RTS are set. I'm facing the same issue on both macOS and Windows. I'm using MSP430 boards package release 1.0.3.

#define LED RED_LED

void setup() {                
  pinMode(LED, OUTPUT); 
  Serial.begin(9600);    
}

void loop() {
  Serial.println(millis());
  digitalWrite(LED, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);               // wait for a second
  digitalWrite(LED, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);               // wait for a second
}

There is a release conflict for the libmsp430.so file (also known as libmsp430.dylib) between CCS 6.2 and Energia 18.

enableXtal is a pretty costly function - it runs at startup and if the crystal isn't present, it delays code execution for 2 seconds. It'd be really nice if there were a way to avoid it.

In my recent projects, what I've done is expose "enableXtal" in Energia.h, and give it a weak attribute in wiring.c. This allows me to override it in the main sketch with an empty function, which gets rid of the 2 second delay at startup, but examples that do depend on the crystal work perfectly fine.

The pack_somnium_gcc.sh script is not OS-aware and thus proceeds with the download of the msp430-gcc-6.2.1.16 four times (Linux 32, Linux 64, macOS, Windows).

Making it OS-aware would save time, space and bandwidth!

The Analog Read function does not seem to allow for quick switching between input pins. Often, when switching to a new pin, the routine will return a sample from the previously sampled pin instead.

Below are two routines that might permit for a cleaner implementation of Analog Read. This logic has been used in a system that samples three analog signals, on a round-robin basis, in excess of 30k times/second (hence over 90k samples per second).

 // --- analogPinSelect is a routine that is used by 
 //     myAnalogRead(int pin) in order to select the designated A/D pin
void analogPinSelect(int pin){
  if (pin < 8){
    ADC10CTL0 &= !ENC;      // disable conversion
    ADC10CTL1 = pin << 12;  
    ADC10CTL0 |= ADC10ON + ENC + ADC10SHT_0; 
  }
}

// --- myAnalogRead(int pin) is a routine that reads a given A/D
//     port on an MSP430G2553.  The routine is blocking in nature
//     and it is not particularly efficient, but it avoids some of the 
//     problems of the build in Energia "analogRead(int pin)" routine
//    in particular, this routine can cleanly switch across several A/D input ports 
//    whereas Energia's analogRead() has problems when using more than one port.
int myAnalogRead( int pin){
  analogPinSelect(pin); // select the pin
  ADC10CTL0 |= ADC10SC; // start conversion
  while(ADC10CTL1 & ADC10BUSY);
  return ADC10MEM;
}

The MSP430FR4133 uses software I²C on pins 9 and 10 for compatibility. However, only SCL signal seems to be generated.

The same sketch with the same INA226 BoosterPack works fine on the MSP430FR6989 LaunchPad. According to the schematics, SCL and SDA have 10 kΩ pull-up resistors.

I'm using MSP430 boards package release 1.0.3.

#include "Wire.h"

#define INA226_I2C_ADDRESS 0x40
#define INA226_REGISTER_MANUFACTURER_ID 0xfe
#define INA226_REGISTER_DIE_ID          0xff


int16_t read16(uint8_t address)
{
  int16_t value = 0;

  Wire.beginTransmission(INA226_I2C_ADDRESS);
  Wire.write(address);
  Wire.endTransmission();

  Wire.requestFrom(INA226_I2C_ADDRESS, 2);
  while (Wire.available() < 2)
  {
    Serial.print(".");
  }

  value = Wire.read();
  value <<= 8;
  value += Wire.read();

  return value;
}


void setup() {
  Wire.begin();
  Serial.begin(9600);
}

void loop() {
  Serial.print("5449 ? ");
  Serial.println(read16(INA226_REGISTER_MANUFACTURER_ID), HEX); // 5449
  Serial.print("2260 ? ");
  Serial.println(read16(INA226_REGISTER_DIE_ID), HEX); // 2260
  delay(100);

}

The energia framework generates define which identifies the selected board.
e.g.
-DENERGIA_MSP-EXP430F5529LP
this is an invalid define as defines does not allow the '-' character.
the compiler also reports an warning which i assume corresponds to that.
:0:12: warning: missing whitespace after the macro name [enabled by default]

This might happen for other boards as well - so a replace of '-' with '_' might be a good option when generating the defines.

ASCIITable no longer compiles after this check-in robertinant/EnergiaNG@c0956a8

USCI_Ax and USCI_Bx share the same TX interrupt vector. When I moved the I2C files from the core into the Wire library, the i2c_xyz_isr function where no longer picked up because the Wire library is not included and hence not compiled / linked. Reason why I moved them into the library is that that is where there belonged all along.

__get_SR_register()
__data16_write_addr(x,y)
are not supported by GCC4.6

Using an msp430g2553 I created a small sketch. The informational message says it is using 782 bytes however it is really using 872 + 32 (interrupt vectors) bytes

Sketch uses 782 bytes (4%) of program storage space. Maximum is 16,384 bytes.
Global variables use 32 bytes (6%) of dynamic memory, leaving 480 bytes for local variables. Maximum is 512 bytes.

I tried to install the msp430 package from the url above into the real Arduino version 1.9.10 it failed with this message:

Error downloading http://energia.nu/downloads/download_core.php?file=msp430-1.0.1.tar.bz2

From @croberts15 on January 28, 2016 17:1

The default analog read resolution should be consistent across all boards at 10 bit, however when testing I was getting a default of 12-bit for 5529, 6989, and tm4c123. The msp432 was 10-bit.

In file MSP-EXP430FR5994LP/pins_energia.h lines 106 and 110, two analog inputs A5 and A9 share the same pin 28.

static const uint8_t A5  = 28;
