FFO-based serial port to send
The main function of the realization of a serial transmitter, which sends the data is read from the FIFO. That is, as long as there is data in the FIFO, serial transmitter will start to send data out. The serial transmitter consists of three modules. datagene module generates every 1s 16-byte increments of data that will be written fifo232 in case of a 256-byte size The FIFO. Once detected, the FIFO data, uart_ctrl module will be data in the FIFO Read out and sent through the serial port. We can use a serial cable to connect SF-EP1C board and PC, via the serial Are port debugging assistant view the received data is a set of constantly increasing data.
