Resolved! RX/TX pin swapping

We are using the STM32U575RIT6 device and performed a RX/TX swap on LPUART1, ports PC0 and PC1. When we enabled the Swap TX is properly transmitting out of PC0. But we are unable to read anything on the new RX pin PC1. Other than enabling the pin swa...

Resolved! STM32L152 UART code missing in driver

Good Day,Recently I started working with a new MCU (STM32L152). I ported some UART code to handle received data from a different MCU, which worked fine. But as soon as I started testing edge cases I saw some weird things happen. I am using the DMA on...

Resolved! RS485 DE enable

Hi,I am implementing RS-485 communication on the STM32G491. Based on available references, I’m currently using a custom GPIO pin for the DE (Driver Enable) signal, since the default USART1_DE pin is already allocated for another function. In the RS-4...
