msp430_programmer.py

Blog Post (hackaday.io)

This is a script for programming a hex file into a msp430. It is designed for and tested on a MSP430G2211 and MSP430G2231 MCU. It is intended to be used alongside the JTAG-Programmer CubeIDE project installed on a NUCLEO-L432KC.

Useage

To use this scipt you need a .hex file. I reccommend writing a program in Ti's Code Composer Studio and compiling it there. Before compiling, make sure that you enable compiling hex file in preferences and set output type to intel hex.

You also need a NUCLEO-L423KC with the project JTAG-Programmer installed on it.

Begin the script by typing in a terminal:

$ python3 msp430_programmer.py <tty port> 115200 <hex file>

• tty port can be found by doing ls /dev/ | grep tty in a terminal and finding which one is the NUCLEO
• baud rate is constant 115200
• hex file must be an intel hex file

$ python3 msp430_programmer.py /dev/ttyACM0 115200 hello_world.hex
