How do I transmit data via UART, which is not connected to the ST-LINK to a Windows computer? Which drivers are needed?

This question uses the STM32H723So I am transmitting data at 7MB/s over UART to a PC. Currently, it uses UART3, which is connected to the ST-LINK. When I view the data on the Windows PC it is fine but every now and then the received data is wrong, an...

What are the potential reasons for Hardfault?

I have a custom board with a basic crystal oscillator connected to the High Speed Oscillator pins of my STM32F446RET6. I assembled 2 boards and found out only 1 board works fine but the other does not. I replaced the crystal and the capacitors but I ...

RTC lags

Hi I am having lags in the RTC after one day. I am currently using the Nucleo L476RG board, the RTC oscillator is LSE and my CubeIDE version is 1.6.1. It seems as if in the time intervals where I do not read the RTC it is not updated. The next table ...
