Hi everybody!First of all sorry for my language. I just started to learning programming of STM32. My problem is that i made a delay function. I wanted to test it with the input capture mode. I setted the prescaler to 16000 - 1. I wanted to get an 100...

STM32 RTC Fixed to 21st Century?

Hey everyone. During my work with the RTC on the STM32H753, I've noticed that you can't set the century or millenium in the Date Register (RTC_DR). Is this correct?Therefore, I can infer that the hardware is hardcoded to work within the 21st Century,...

STM32F105RCT6 vs GD32F105RCT6

HiDue to a shortage of STM32F105RCT6 we need to use the GD32F105RCT6. So a firmware that is running on the ST MCU needs now to run on the GD MCU. Does anyone know if the GD32F105RCT6 is fully compatible with the STM32F105RCT6?Not just the pinout but ...
