I've yet to try serial comms with the chip. For I2C comms, found this interesting thing (but for I2C as peripheral, not host); turns out that there is a new PocketBeagle 2 (finally a different processor compared to old BeagleBone Black, but not a lot of RAM), and they are using a 24-pin MSPM0L1105 chip too. I wondered what for, and apparently it is for EEPROM and ADC emulation. Source code is here:
https://openbeagle.org/pocketbeagle/mspm0-adc-eeprom/-/releases

I just briefly looked at it (on mobile phone since I'm not near a PC) but was amusing, they have emulated an Analog Devices AD7291 chip : ) useful because that's supported by Linux drivers. They have also emulated a standard 4kByte EEPROM, both being accessible via I2C just like the real devices.

Nice post Jan.

That FFT code could be extremely useful! Good to see CCS looks a _lot_ cleaner than it used to, and that SysConfig feature is integrated well.

First project that uses serial comms over the USB

It's based on the example uart_rw_multibyte_fifo_poll

I had to adapt controller, UART pins and LED pin. All via SysConfig:
