利用EGO1数模混合口袋实验平台上的蓝牙模块与板卡进行无线通信。使用支持蓝牙 4.0 的手机与板卡上的蓝牙模块建立连接，并且通过手机 APP 发送命令，控制 FPGA 板卡上的硬件外设。(The Bluetooth module on the EGO1 digital-analog mixed pocket experimental platform is used to communicate with the board. The Bluetooth 4.0-enabled mobile phone is used to establish a connection with the Bluetooth module on the board, and commands are sent through the mobile phone APP to control the hardware peripherals on the FPGA board.)

说明：  基于RTL8211以太网芯片开发的以太网通信代码，使用Quartus编程，FPGA板子为开发者(Ethernet communication code based on rtl8211 Ethernet chip, using quartus programming, FPGA board for developers)

Based on the verilog such as frequency meter accuracy, except for measuring frequency can also measure pulse width of empty measure than 32 counts of data through the simulation SPI serial output to SCM processing and display

使用STM32官方提供的DSP库进行FFT，虽然在使用上有些不灵活（因为它是基4的FFT，所以FFT的点数必须是4^n），但其执行效率确实非常高效，看图1所示的FFT运算效率测试数据便可见一斑。该数据来自STM32 DSP库使用文档(. Using the official DSP library provided by STM32 for FFT is not flexible in use (because it is the FFT of base 4, so the number of FFT points must be 4 ^ n), but its execution efficiency is really very efficient, as can be seen from the test data of FFT operation efficiency shown in Figure 1. This data comes from STM32 DSP library usage document)
