Other Parts Discussed in Thread: LP-MSPM0L1306, , MSPM0L1306, SYSCONFIG
Tool/software:
Hello Support-Team,
I assembled the HDC2010 on my product launchpad LP-MSPM0L1306 and now i am trying to get it worked. So, I am not using the EVM.
Is there somewhere an example code for the HDC2010 with the MSPM0L1306 (or another MCU from TI)?
I found these files attached to this question. Is there a latest updated version of these codes?
Thank you very much
Best regards
Maunil Chopra
