Can STM32H7 be made into a switch?What peripheral chips are needed?

I found that STM32H7 supports the boundary clock in the IEEE1588 standard. Can STM32H7 realize the boundary clock function as a switch? What peripheral circuits are needed?

WHat will happen if one of the ADC channel is removed from the couple of connected ADC channels?

Hi,i have a problem with controller stm32f030c8t6 where i have connected two ADC channels to read the sensor values(Temperature &humidity). if i remove one of the ADC channel from the sensor output pins i will get fluctuating values from minimum to ...

Thanks a lot for your great comments.

I had a lcd with fmc on stm32f429 project working properly with Fw1.14.0 . But when migrate to Fw 1.24.1 ,it is not working.No change on the code , FMC init code are same except " FMC_NORSRAM_TimingTypeDef Timing" initialization . Any idea ?

 FMC_NORSRAM_TimingTypeDef Timing; FW 1.14 FMC_NORSRAM_TimingTypeDef Timing; = { 0 }; FW 1.24

Option bytes in firmware

Hello,Device: STM32L443CCUI am trying set option bytes values in firmware as a ROM constants. The idea is firmware will have option bytes embedded, and when firmware hex will be flashed, it will also flash new option bytes.So I did following implemen...

STM32 stack and heap

Hello I want to understand allocating stack and heap size, I am using stm32f767zi with 512Kbyte RAM memory (0x80000 bytes) so what I understand is this memory should be split between only the stack and heap (if there is something else please tell me)...
