MSPM0L1306: PWM with frequency of 38KHz does not work

preciso usar a saída PA17 do VQFN32, pino físico numero 21, com o timer TIMG4, porem ele não consta como opção no arquivo .syscfg..

no datasheet mostra PA17 como opçao do TIMG4...

Como faço para usar o PA17 no TIMG4 ?

Hi Diego

Thank you so far.

Option PA17 appears, but none of the pin options for channel 0 work. For channel 1 it's ok. And I need to use the PA17.

Previously I had looked at the schematic of the kit, to seek answers, actually the pin is connected between micro and terminal... not jumpers

Do I need to be concerned about your quote "be aware that the PA17 is a standard pin type with Wake" ?

Hi Tiago,

Since you have a PIN that has UART as its option, there are some jumpers you may need to re-arrange in order to make it work due that sometimes it can think you are trying to use UART rather than TIMG. That's why you need to see if there might be any jumpers that could be interfering with your PIN. 

For the latter, that's something you should just be aware of. For more information, please refer to the datasheet.

Diego, I don't understand, the PA17 is connected directly to the micro, without jumpers, I can use it as a digital output, but it doesn't work as PWM of the TIMG4...

Hi Tiago,
I'll look over this problem today and tomorrow.

Regarding what I meant by jumpers, please refer to the following pictures. You have multiple of these jumpers around your launchpad, and sometimes depending on how they are connected, they can affect the functionality of some PINs of the launchpad. That's why I want you to make sure that the jumpers are not affecting that specific PIN.

Best Regards,

hi Diego

According to the diagram, the PA17 does not have a jumper connection. From what I saw in the manual, no jumper has action on the functionality of the PA17.

Hi Diego, Thanks for the support.

At the beginning I couldn't generate frequencies higher than 16Khz on the PA17, CH0. And on CH0 PA15 normally. This morning I started again and I was not successful, until I changed the timer parameters so much, it worked, now it is working, including all jumpers in the standard way. I don't know where the problem was, or if there was a problem.

But thank you for your effort to help me solve it.

Thanks
