NRF82532看门狗程序，能很好的保证单片机系统正常工作，性能十分可靠。(The NRF82532 watchdog program can ensure the normal operation of the single chip microcomputer system and its performance is very reliable.)

这是AD9910 DDS芯片的verilog配置程序，经调试已成功，可以供大家参考。(AD9910 verilog configuation.)

Microchip公司的一款EEPROM芯片24LC1024的源程序，包括EEPROM的读和写 (Microchip EEPROM chip 24LC1024 a company source, including EEPROM read and write)

基于proteus的按键控制，仿真图，源程序，有声音和显示(Button control, based on proteus simulation diagram, source code, there is sound and display)

我使用的是F103VET6，软件IIC控制，改引脚配置后可方便移植。 SDL连接PB6、SDA连接PB7、CS连接高电平，SDO连接高电平的话模块的写地址为0x3A、读地址为0x3B··· ···(I use F103VET6, software IIC control, pin configuration can be easily transplanted. SDL connects PB6, SDA connects PB7, CS connects high level. SDO connects high level telephone module with write address of 0x3A and read address of 0x3B.)

89S52 单片机 + 74HC595 + 组成的8X8 LED 点阵驱动显示程序，Keil C环境编写，带显示字符压缩／解压源／显示／代码。(89S52 composed of lattice-driven 8X8 LED display program, Keil C environment preparation, showed a band of characters compression/decompression source/Display/code.)

在Keil环境使用stm32F407写的带死区控制的互补PWM驱动，很适合做双路电机控制，这是一个完整的工程，可以直接编译使用(In complementary PWM Keil environment stm32F407 write with dead-time control of the drive, it is suitable for dual motor control, which is a complete project, can be directly compiled using)
