VHDLSourceProgramofReadDAatasFromSRAM
- 从SRAM中读取数据并显示的VHDL源程序,了解串口通信的基本原理,了解VGA现实图像的方法和原理。-VHDL Sorce Program of Read Datas From SRAM
fifo
- 同步FIFO 创建一个256x8大小的同步FIFO,并通过串口发送数据初始化FIFO,FPGA内部读取FIFO的数据通过窗口发送到PC-FIFO
IS61WV51216BLL
- 备注:使用的是VeriLog HDL语言 软件环境xilinx ISE 10.1,硬件:高教仪EXCD-1FPGA电路板。FPGA信号:spartan-3e . 功能编写硬件描述性语言实现FPGA对板上外设SRAM IS61WV51216BLL的读写,通过串口发送到上位机上,使用串口助手显示读取的数据。-Note: Use the VeriLog HDL language software environment xilinx ISE 10.1, hardware: Higher M
read_fpga
- 下载到avr单片机上以后,单片机与电脑通过串口线连接,打开单片机,会在电脑串口工具上自动提示,可以读取某个外部地址上的数据-Downloaded to the avr microcontroller, the processor with the computer via serial cable, open the microcontroller, the computer will automatically prompt on the serial tool, you can read t
uartfifo
- 基于FIFO的串口发送机设计。主要实现一个串口发送器功能,该发送器的数据是从FIFO 中读取的。也就是说,只要FIFO 中有数据,串口发送器就会启动,将数据发送出-FIFO-based serial transmitter design. A serial transmitter function of the transmitter data is read from the FIFO. In other words, as long as there is data in the FIFO,
series_rxd_timing
- 接收异步串口数据,将数据写到接收fifo中,可设置超时来接收多字节数据,当设置超时时间内未出现数据,ready信号有效,表示接收完整数据包,可从fifo中读取数据。-Receive asynchronous serial data, the data is written to the receiving fifo, you can set the timeout to receive multi-byte data, set the timeout period when the data d
20130607UART
- 读取温度传感器DS18B20数据并通过串口发送到上位机。程序开发是基于altera 的EP2C8Q208芯片。-Read the temperature sensor DS18B20 data and sent it to the host computer via the serial port. The program development is based on the the altera s cyclone II device :EP2C8Q208.
uartfifo
- 该实验主要实现一个串口发送器功能, 该发送器的数据是从FIFO中读取的。也就是说,只要FIFO中有数据,串口发送器就会启动,将数据发送出去。 -The main experimental realization of a serial transmitter function, which sends the data is read the FIFO. In other words, as long as there is data in the FIFO, serial transmitt
IIC读写EEPROM发送到PC串口
- 能实现用IIC读EEPROM并且将读取的数据通过串口发送到PC端,以及在PC端通过串口发送数据给FPGA,再利用IIC将数据写入EEPROM(The program can realize that FPGA read the data from EEPROM by IIC and then send it to PC by UART,and that PC send the data to FPGA by UART and then write the data to EEPROM by
spi_master
- SPI通信:串行flash的读写擦除命令通过SPI接口进行通信。? CPU芯片与FPGA通过SPI接口进行通信。? 其他功能集成电路芯片参数寄存器配置。例如DAC芯片内部有很多寄存器(因为芯片有很多功能,要通过设置寄存器不同的开关来打开或关闭相应的功能,一上电去初始化寄存器)需要我们去配置。FPGA一上电也是通过配置芯片里边来读取数据,然后配置FPGA内部的SRAM。FPGA是读取FLASH里边的串行数据,读取完校验完才配置到我们的FPGA的SRAM中去。速度比串口快,而且是同步传输。(Th
