I am testing Rx handler logic on a STM32H7 based board. Pins PD0/PD1 are set as Rx/Tx (huart4) with Global Interrupt set. The uart is setup to interrupt on Idle...HAL_UARTEx_ReceiveToIdle_DMA(_uart, _JoyRxData, BROADCAST_CMD_SIZE);and the interrupt i...

SOLVED!On our custom board with the STM32H7 processor, I was using DMA to receive messages over serial COM. That involved using the combination of HAL_UARTEx_ReceiveToIdle_DMA and HAL_UARTEx_RxEventCallback. Also, I had the baud rate set to 1000000. ...

One more thing to mention. The communication is set to take place at baud rate 1MB, which is higher than anything I've used before. I'm going to try testing at lower baud rates. Will write back if that makes a difference!

Hi @SofLit thanks for writing back!The processor is STM32H747AI used on a custom board, intended to go into a product. The source of serial data is a tool (a joystick) that is designed around an OpenCM9.04 board which incorporates the STM32F103CB MCU...
