If the FIFO is full and there is another piece of data to enter, it is either dropped (the newest data is lost) or the oldest … Hello All, I have an issue getting the interrupts to work on a Uart placed in the FPGA fabric and connected to the Zynq processor on a Cora Z7-10 board. com A UART (universal asynchronous receiver transmitter) is a key component of RS-232/422/485 serial communication hardware, and documents that introduce UARTs are readily available. Streams are pathways where memory can flow, and each processor has 8 to work with. Frame time is based on baudrate. I'm not sure about the STM32 UART HAL but it should also fire the callback if a specific time has elapsed since the last byte (or if data in the buffer is older than x) This way you can have a large buffer but still respond to incoming data quick enough if the data happens to stop with the buffer not full. STM32高速串口通信DMA收发实现 测试平台 实现功能 收/发环形缓冲区 不定长度接收处理 高速（1. Interrupt handler appends characters to a FIFO from one side.
