Resolved! STM32 RS485 interface with 12MBit/s
Hello team,is one of the STM32 MCUs suitable to run a RS485 interface with 12MBit/s? This is related to a UART interface which should be clocked by at least 192MHz.Best regards,Jochen Ruopp

Generating PWM modulated sinewaves fails sometimes on some outputs - G431RBT6
I have setup Timer 8 to generate PWMs, to modulate a sinewave. I use preload, but that is only used once.I have debugged and compared the registers, but i could not find a cause. I have also partially compared the sram bytes, but i could not find the...

Resolved! STM32H743VIT6 ADC different channel sampling rates
I have two questions. One is how are Y and V distinguished? The other is where can I know what channels these Direct channels and FAST channels include?
PSP switches to the handler stack upon function return
This was a tricky bug to find. I am doing context switching. Everything seems to working well until a context switch happens while one of my tasks has called a different function. Specifically, HAL_GetTick(). To be clear the switch is happening while...
