Deat ST Hello,This my first question to you in this forum.Does ST has peripheral examples using HAL library or standard lib for STM32f4?I am installing the packs from the pack installer from Keil.Could I adapt examples for my STM32 if ST provide a g...

Check FlashErased or Readout InternalFlash ECC on STM32H7

I'm working on the STM32H7 series, and in my scenario the data to be written might be the erased-state byte (0xFF) all over the flashword. In this case I'm unsure whether or not the ECC may change.What is the idiomatic way of checking if the bytes ha...

Hello, I am using stm32f103 in my project. Software as GPIO_PinRemapConfig (GPIO_Remap_SWJ_JTAGDisable, ENABLE); I disabled it with the command. But now I can activate it back, I don't know how.
