WebJul 11, 2024 · I have run into a DMA-related issue while trying to implement an application for the STM32F407VG which receives data from a sensor via UART. The sensor sends a 162-byte data packet at 912600 baud every 10ms with pauses in between. Because the MCU is already quite busy, i want to use DMA.
