I am using a STM32F746zg uc connected to a W25Q80 Flash memory. In my initialization I erase a page then memory map the flash and then I read a pointer to that address. I expect to read 0xFF as the flash has just been erased, however I read 0x88. I'm...
Hello. I have packet each 200ms (8 byte) and i have sometimes from computer register set function, again 8 bytes.And time to time getting USART ovverrun error. That is not a big deal, but i just don't want to miss correct register write to MCU event....
