STC TQFP-44 LQFP-44封装库(TQFP-44 LQFP-44 package library)

ATMEMA16 写的飞利浦的D12 USB接口芯片的程序 编译环境为ICC AVR(ATMEMA16 write Philips D12 USB interface chip process for the ICC AVR compiler environment)

keil5编写的基于STM32F103T8的模拟HX711驱动程序(Keil5 prepared by the HX711 simulation based on STM32F103T8 driver)

说明：  STM32H7串口DMA的实现代码，供参考(STM32H7 Serial Port DMA)

以前电子竞赛时写的M3 ARM控制TFT液晶显示正弦波波形可以连贯的左移，没有闪烁感，我还写了一个也是正弦波左移，只不过有一点闪烁，我也上传了，你们需要可以找一下！(Writing contest before the electronic control M3 ARM TFT LCD sinusoidal waveforms can be coherent left, no flashes, I also wrote a sine wave is left, just a little flicker, I also uploaded, you need to be able to Get it!)

本设计主要实现用按键控制步进电机四相单拍、四相双拍和四相八拍三种方式切换， 正、反转及其加、减速，并能在LCD上显示其运行状态（速度和转向）。(The design of the main keys to achieve control of stepper motor with a single shot four-phase, four-phase two-and four-phase eight-shot shoot three ways to switch Positive, reverse its acceleration, deceleration, and in its operational status on the LCD display (speed and steering).)

说明：  ltc6811的使用配置程序，可以直接使用。(ltc6811,SPI use,can directly use)

这是LCD12864的源程序。是我现在看到最规范的程序！(This is LCD12864 of the source. I now see the standard procedure!)

实现RC522射频芯片的读写，扣费，注册，和充值等功能，51单片机绝得可以用(RC522 RF chip to read and write, chargeback, registration, and recharge function, 51 MCU must have to be able to use)

说明：  BIN文件转换成带地址的S19文件的工具，在windows平台下运行，一直在用比较方便。(The tool for converting BIN files into S19 files with addresses, which runs on Windows platform.)
