Description: 用FPGA实现了RS232异步串行通信，所用语言是VHDL，另外本人还有Verilog的欢迎交流学习，根据RS232 异步串行通信来的帧格式，在FPGA发送模块中采用的每一帧格式为：1位开始位+8位数据位+1位奇校验位+1位停止位，波特率为2400。由设置的波特率可以算出分频系数，具体算法为分频系数X=CLK/(BOUND*2)。-Using FPGA to achieve the RS232 asynchronous serial communication, the language used is VHDL, In addition, I also welcome the exchange of learning Verilog, according to RS232 asynchronous serial communication to the frame format, in the FPGA module used to send each frame format : the beginning of a bit+ 8-bit data bit+ 1 bit odd parity bit+ 1 bit stop bit, baud rate for 2400. By setting the baud rate can be calculated at the frequency coefficient, the specific algorithm for the sub-frequency coefficient X = CLK/(BOUND* 2). Platform: |

Description: 在ISE环境下，用VHDL语言实现RS232串口设计，实现串口通信。通过串口调试工具向
0000000UART发送16进制数，FPGA将UART接收到的串行数据转换为并行数据，并在8个
LED灯上输出显示；同时，并行数据又被重新转换为串行数据，重新送给RS-232接口，并在
串口调试工具上再次显示，SW0为复位键。
比如：串口调试工具发送两位16进制数，然后能在LED上显示，并且重新在串口调试工
具上显示。串口调试工具设置：波特率设为9600，默认奇校验。-In the ISE environment, using VHDL language RS232 serial port design, serial communication. Through the serial debugging tool to
0000000UART Send a hexadecimal number, FPGA serial data received by the UART converted to parallel data, and 8
LED lights on the output display the same time, parallel data has been re-converted to serial data, re-sent to the RS-232 interface, and in
Serial debugging tools on the show again, SW0 for the reset button.
For example: serial debugging tool to send two 16 hexadecimal number, and then can be displayed on the LED, and re-debugging in the serial port
With a display. Serial debugging tool settings: baud rate is set to 9600, the default odd parity. Platform: |
