I configure 6 channel GPIO pins to generate PWM signals to control 3-phase bridge. There is one pin(PC13) sometimes stop to generate signal. Even we reset 3.3V power voltage, it won't recover. one time I inject 20k square wave to pin PC13 to verif...

I am trying to get the temp of the internal temp sensor.. I tested on both MB1367 demo board and my own board.I use jumper to connect JP8 pin2 and pin 3 to get Vref as 3.3V. I attached the cubmx and main file of my simple code. The issue is I always...

Thanks for your answer. How can we explain the processor can't get Reset properly. I guess it is because of PA7 has 1V voltage. But I am not sure. The issue didn't come up frequently. It is very hard to verify.

Thanks for solving issue for me. ?Finally, I figured out. It should be getvalue()*3.3V/3.0V. I did reverse. But I did found another thing. I get the temp CAL values which are 1042 on 30 degree and 1375 on 110 degree. Then I get the slope is 3mv/C. ...

Do you have sample code and cubemx I can use directly?

It translates to -29 degreeC. I also try the maximum cycle time as well. Same value.
