AXI UART 16550 v2.0 .xilinx 4 PG143 November 18, 2015 Product Specification Introduction The LogiCORE™ IP AXI Universal Asynchronous Receiver Transmitter (UART) 16550 connects to the Advance Microcontroller Bus Architecture (AMBA®) AXI and provides the controller interface for asynchronous seri...
完整记录如下: 更改AXI UART 16550 FIFO 大小,步骤如下: 备份Vivado/your_version/data/ip/xilinx/axi_uart16550_v2_0 和 /Vivado/your_version/data/ip/xilinx/lib_srl_fifo_v1_0 文件夹 如果您的设计中有 AXI_UART_16550 IP 核,请将其移除,保存设计/项目并关闭 Vivado 清除项目目录中的 your_project.c...
需要注意的点是对寄存器如何操作,需要查看对应IP核的手册,这里使用AXI_uartlite,IP核 还有ip核为 AXI UART 16550,也能够支持zynq器件 IP核文档查看, 比如以下是写寄存器的值和对应的操作 代码如下: intfd =0; if((fd = open("/dev/mem", O_RDWR | O_SYNC)) ==-1) ... MAP_uart_addr[0] = mmap...
本文介绍的是AXI UART Lite这个IP核,里面实现了读写串口数据等基础功能,Vivado还有另一个功能更强大的AXI UART16550的IP核,其在前者的基础上增加了一些输入输出接口以及寄存器,能动态地设置parity以及word length等参数。 在使用IP核后,我们只需要实现AXI4-Lite总线协议就能与主机进行串口通讯而不用理会具体的实现细节...
