MSPM0 project with VS Code, CMake and GCC - part 4: EasyL1105 example

Jan Cumps

In this blog series, I build a Texas Instruments MSPM0 example with VS Code as IDE, and CMake as build infrastructure.
In posts 1 - 3, I created an end to end flow, from install over build to debug.
In post 4: testing it out on the EasyL1105: A Dev Board for the TI ARM Cortex-M0+ L-Series with a blinky.

Project and Changes

I used TI's existing pwm_led_driver example for the L1105 (project is attached at the end of this post).

Changes to SysConfig:

  • different GPIO for LED:
    the code I attached uses PA14, to reflect my setup. I have a blue LED on PA14..
    If you use an unaltered EasyL1105 board, edit pwm_led_driver.syscfg and change PA14 to PA26 on line 27. That's where one of its LEDs sits.

Changes to the scripts:

  • in CMakeLists.txt I changed the project name, and the file names of the sysconfig and .c file
  • in launch.json, I changed the device to MSPML1105 on line 32

Debugger

I used the on-board XSD110 from one of my LaunchPads. Works equally well with a standalone XSD110.

On the EasyL1105, I removed all jumpers (in particular the power ones). On the LaunchPad, I removed all jumpers that connect the debugger to the controller. Then I routed Ground, 3V3, nRST, SWDIO and SWCLK from debugger to EasyL1105 J5 (SWD connector).

I selected the project in VS Code CMake extension. Selected GCC toolkit. Config, Build.
After that, started a debug session. All worked. The code got loaded on the MSPM0L1105, and the LED started glowing...

The build script also generates a .hex firmware compatible with shabaz'  python programmer.

  • The MSPM0 Python programmer has just recently been updated, I set AI on it, to give it a decent scroll buffer, and also show the status at the bottom. Now it looks like a real text-based app.

    Also, there is an Android port, here:

    https://github.com/shabaz123/easy_mspm0_prog/releases/

    The Android version allows for installing local .hex files on the phone, or from a web link (can be a GitHub repo, and if there is also a .json file in the folder, it will use that as metadata to print some firmware detail). I thought a mobile app would be useful so anyone can upload firmware a bit easier. There may be minor bugs with it, since it was AI generated! But it generally functions with the odd quirk or two (and left to its own devices, the AI generates really ugly, busy layouts, and with horrendous colors.. I asked it to then tone it down, but there are still many pointless little graphic icons etc.). I need to learn how to specify a simplistic apple-style mentality/design language from the start, so it doesn't ever get to this stage again.
