cc3200emt-core's Introduction

The Energia project is no longer maintained.

Energia, the fork of the Arduino IDE and SDK for the LaunchPad boards, is no longer maintained. The last release 1.8.10E23 was published in December 2019.

The official tools from Texas Instruments are Code Composer Studio, based on Eclipse with an online variant, and the SimpleLink SDK for the ARM Cortex-M MCUs.

What Is Energia?

Energia is a fork/port of Arduino for the Launchpads, or boards with MCUs from Texas Instruments.

What Are the LaunchPads Supported?

Energia provides native support for the following LaunchPads:

LaunchPad with MSP430G2231, MSP430G2452 or MSP430G2553 or LaunchPad
Experimeter Board with MSP430FR5739 or FraunchPad
LaunchPad with MSP430F5529 or FattyPad
LaunchPad with MSP430FR5969
LaunchPad with Stellaris LM4F120 or Tiva C Series TM4C123 or StellarPad
Connected LaunchPad with Tiva C Series TM4C129

What Are the BoosterPacks Supported?

Energia includes ready-to-use libraries for the following BoosterPacks:

Anaren Air CC110L BoosterPack
Educational BoosterPack MKII
LCD Sharp BoosterPack
CC3000 SimpleLink WiFi BoosterPack

Clone instructions:

Energia consists of the main repository and a submodule called emt. The emt tree contains the sources for the Energia MT (Multi Tasking) feature that is based on TI-RTOS/SYSBIOS. To clone Energia and the emt submodule:

git clone --recursive https://github.com/energia/Energia.git

If you already have a clone of Energia then:

git submodule update --init --recursive
git submodule sync
cd emt
git pull

SIMPLELINK-OPENOCD as Alternative to DSlite

Texas Instruments provides the Open On-Chip Debugger (OpenOCD) for SimpleLink™ Connected MCUs (SIMPLELINK-OPENOCD).

SIMPLELINK-OPENOCD supports flash programming for CC3220SF internal flash.

As an alternative, the OpenOCD repository is located at http://git.ti.com/sdo-emu/openocd.

OpenOCD is well documented at http://openocd.org and widely used. It acts and a server for GDB like GCC 6.3.1-20170620 arm-none-eabi-gdb.

Documentation on http://ti.com and http://e2e.ti.com is rather scarce.

The same configuration against the CC3200 required setting sp and cp manually.

Workshop — Uploading to the CC3220 LaunchPad Flash

#11 solves the issue for RAM, but how to upload with Energia to Flash on an easy way?

UART1 at 2400 bps is not working with CC3200EMT.

Hi,
I was previously using uart1 on cc3200 launchpad without emt. It was working there.
But when I changed the board to cc3200emt, then on using uart1 I received no output on serial console.
my code:=

void setup() {

pinMode(GREEN_LED,INPUT);
Serial.begin(115200);
Serial1.begin(2400);
}

void loop() {

if (Serial1.available())
{
int inByte = Serial1.read();
if(inByte == '\r')
Serial.write("\r");
Serial.write(inByte);
}
}

CC3200 EMT — Error, size if data (1234045) is too big to write

From @rei-vilo on December 21, 2016 15:25

Once #12 has been fixed with suggested command, upload fails due to too big file to write.

Resulting MultiBlink_CC3200.ino.elf for the MultiBlink.ino example weights 1234045 whereas arm-none-eabi-size MultiBlink_CC3200.ino.elf gives 33833.

Uploading to the CC3200 SensorTag

Uploading to the CC3200 LaunchPad from Energia requires a specific configuration of the SOP jumpers.

How to manage to upload from Energia to the CC3200 SensorTag?

I've found the SOP 0-1-2 on the schematics (swrc337) but how to use them with Energia?

Add support for CC3235

Same as energia/cc3200-core#34

CC3220SF: analogRead() Returns 1023

The analogRead()on the minimalist example below always returns 1023.

Placing and removing jumper J14 OPAMP EN has no effect.

Same for using 23 instead of A0.

The exact reference of the board is CC3220SF Rev-A. Pin 23 is connected to the middle point of a 10 kΩ potentiometer, connected to +3.3V and GROUND.

Same code works fine on the CC3200 LaunchPad, with taking care not to exceed 1.7 V.

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly: 
  Serial.println(analogRead(A0));
  delay(1000);
}

CC3200 EMT — Specific Compilation Procedure?

From @rei-vilo on December 21, 2016 15:38

When compiling the MultiBlink.ino against the CC1310 EMT and MSP432 EMT, compilation generates two files, MultiBlink_CC3200.ino.cpp and main.cpp.

The former concatenate all the different task into one file and the latter declares the tasks to the RTOS.

However, compiling the MultiBlink.ino against the CC3200 EMT does not generate the main.cpp.

Has the compilation procedure changed?

/* magic insertion point 769d20fcd7a0eedaf64270f591438b01 */
