In STM32CubeMX, I'm trying to set TIM1 for PWM mode 1 for the STM32L412KB. This does not appear as one of the options.

Here is a screen shot of the options. It appears that PWM modes 1 and 2 are missing.

Hello DWalk.1,

Could you please share your .ioc file for further check ?

Thanks in advance.

Khouloud,
It is attached. Note that I manually changed the .ioc file to include the correct PWM parameters and the STM32Cube generates the correct code. Its just that now the STM32Cube program complains about invalid properties with the configuration and asks me if I want to generating the code anyway.

Hello DWalk.1,

I can't find any attached .ioc file, please check that you have correctly attach it (the screenshot doesn't reveal so many details). Otherwise opening a new project using STM32L412KBTx, "PWM mode 1" / 2 could be selected if you have already selected the appropriate Channel Mode (Please see attached screenshot).

The issue isn't reproduced from my side, the code is generated without any problem and without showing any warning message.

Khouloud,

That was the problem exactly. I was set to "Output Compare Cx CNx", not the PWM mode. Once I changed it, it is working fine.

Maybe I get an award for the most baseless post of the week?

Thanks for you help!
