Communication based on Verilog RS232
no vote
Application background This is achieved through the Verilog hardware description language, the XILINX KINTEX-7 series FPGA RS232 serial communication function. After I personally verified, can realize the function of communication. Key Technology The function of this module is to verify the function of the serial port communication with the PC. Need to install a serial debugging tool on the PC to verify the function of the program. Program to achieve a 10 bit (that is, no parity bit) of the serial controller, 10 bit is a 1 bit start bit, 8 data bits, 1 end position. Div_par Potter serial parameters defined by the program, change the parameters of the corresponding baud rate can be achieved. The procedures set div_par value is 0x104, corresponding to the baud rate is 9600. With a 8 times the baud rate clock cycle time division will send or receive every 8 bit slots so that the communication synchronization.
