LP-MSPM0G3507: MSPM0G3507

Hi，

PA10 and PA11 is reserved as UART communication port with PC through XDS-110 on the EVM board. You need to changes the jumpers position on J25 and J26 or just use other pins to output the PWM signal. 

Best regards,

Cash Hao

Hi Cash Hao11,

thanks so much for the reply. I tried using other pins PB26, PB27 and PA17, PA18. There are still no PWM signals.

Hi,

That is abnormal. Could you send me your code here so I can test on? 

Best regards,

Cash Hao

Hi Cash Hao11,

thanks so much for your prompt response.

Please have a look at the project I used.

Hi,

Could you directly share your code here not through a drive? The drive could be blocked by company.

Best regards,

Cash Hao

Sure Cash Hao11, please let me know if you need any more information. Thanks again for your prompt response and help.

Hi,

Your code is working on my side. I can get PWM signals on those pins. 

Best regards,

Cash Hao

Hi Cash Hao11,

is there any jumper configurations that I need to look into for LP-MSPM0G3507 EVK to generate output from these pins?

Hi Cash Hao11,

I have another LP-MSPM0G3507 EVK and I tried it out on this as well. But I got the same result.

For your information,

Green => PA18

Yellow => PA17

Hi Cash Hao11,

I forgot to mention about this. Whenever I tried to debug, I received this pop-up in IDE.

But I still can run the debug function after I cliicked OK.

Maybe this is the issue??

Hi,

Sorry for the late response. Just back to the office due to the holiday here.

Good to know you are able to observe the PWM outputs. 

That pop-up in IDE means you are using an early sample of MSPM0 MCU. Usually you can click OK and ignore this message. However, there are some changes between early sample and production version. Something like the timer module and etc.. So, the best way for you is to apply some new EVM boards. 

Best regards,

Cash Hao
