} Hi everyone, I have a problem about UART_ReceiveToIdle_DMA. I receive data with baud rate 500000bits/s. I checked the reference manuel, it says stm allows to baud rate up to USART Clock/3 and my clock is 150Mhz. Here is my problem;1) ReceiveToIdle_DMA does not detect Idle. I enabled NVIC and DMA settings and used RxEvent Callback. Even though there is Idle in data, it keeps receiving and writes to all bu
