Description: / This module function is to verify that the basic serial communication functions and PC. A serial debugging tools to verify the functionality of the program needs to be installed on the PC. Implementation of a transceiver a 10 bit (ie no parity bit) serial controller, 10 bit is a start bit, 8 data bits, 1 stop bit. Serial port baud rate law decided the procedures defined div_par parameters, the baud rate can change the parameters. The procedures set div_par the value is 0x145, corresponding to the baud rate is 9600. Eight times the baud rate clock to send or accept every bit of the cycle time is divided into eight time slots so that the communication synchronization. Program of work process: the serial port in full-duplex state, pressing key2 the FPGA/CPLD sent to the PC " 21 EDA" KEY1 reset button. Hexadecimal data string (serial debugging tool set to accept the way the ASCII code) 0-F PC may at any time be sent to the FPGA/CPLD, FPGA accepted displayed on the 7-segment LED
