51单片机编程器制作资料。内有pcb，原理图，物料清单，hex文件。自制成功(51 Microcontroller Programmer production of information. There pcb, schematics, BOM, hex file. Self-made success)

spi读取AT25128例程，全面解析底层，与I2C兼容。(The SPI reads AT25128 routines, comprehensively parses the underlying, and is compatible with I2C.)

AD9851中文资料，为pdf格式，资料比较详细，希望对需要者有所帮助。(AD9851 Chinese data)

单片机数码管测试程序（非常不错的单片机学习程序）(Single chip digital test program (very good))

STM8L052 的LCD段码驱动显示程序。STM8的LCD驱动器驱动比较复杂，没有规律，显示段码8，需要每位对应，本程序使用三个数组和很小的程序实现段码显示。减少了程序量，提高了效率。(LCD Segment drive STM8L052 display program. STM8 LCD driver drive more complex, there is no law, code display section 8, each corresponding to the needs, the program uses three arrays and procedures to achieve a small segment display. Reduction program, improving the efficiency.)

本代码为STM8S903K 无刷无感电机的驱动源程序 应用在电动工具上 属产品级代码 用电位器调速 保护电流40A(The code STM8S903K brushless non-inductive motor drive source Is a product-level code used in power tools speed control potentiometer protection current 40A)

说明：  STM32通过模拟IIC读PCF8574(STM32 reading pcf8574 through analog IIC)
