UART-IP简介

UART的驱动IP核提供波特率设置参数以及用于接收和发送的通信模式。

UART驱动IP核的组成

module Driver_UART(
    input clk_100MHz,
    input Rst,
    input En_Rx,
    input En_Tx,
    input [30:0]Baud_Rate,
    input Rx,
    input [7:0]Tx_Data,
    output Tx,
    output [7:0]Rx_Data,
    output Rx_ACK,
    output Tx_ACK
    );

信号简介

信号类型 信号名称 描述
input clk_100MHz 100MHz clock signal
input Rst Reset signal, active low
input En_Rx Receive enable signal, active high
input En_Tx Send enable signal, active high
input Baud_Rate Baud rate
input Rx Receive signal pin
input Tx_Data Data to be sent
output Tx Send signal pin
output Rx_Data Received data
output Rx_ACK Receive interrupt signal, and rising edge means received signal
output Tx_ACK Send interrupt signal and rising edge represents the completion of sending
