很久以前写的一个数码管取模软件，可做单片机来发辅助…(a MCU tool ,i ve written it when i was a freshman)

说明：  STC15+ST7735 并口驱动，P1口作为并行数据口。(STC15+ST7735 Parallel Port Driver)

NXP LPC11xx 系列单片机IAP在线升级的研究。经过长时间的摸索，研究LPC1114 IAP在线升级，因此写下文档记录方便以后查阅，同时也给需要IAP在线升级的同仁提供参考。文档内容是实践过的，经过多次反复测试(NXP LPC11xx series MCU IAP online upgrade. LPC1114 IAP online upgrade after a long period of exploration, research, write a convenient documented after inspection, but also to the need to IAP online upgrade colleagues to provide a reference. Document content is practice, after repeated testing)

STC89C52单片机的1602显示程序(STC89C52 SCM 1602 display program)

ftdi公司的USB设备通信上位机编程。(The PC programing for FTDI S USB device)

51单片机驱动12864及1602程序，带有proteus仿真(51 microcontroller drive 12864 and 1602, with proteus simulation )

说明：  max30100 stm32 驱动参考例程(Max30100stm32 Driver Reference Routine)

STM32F103C8T6控制PCA9685舵机驱动板(STM32F103C8T6 control PCA9685 steering wheel drive board)

说明：  vb与plc通讯帮助解决vb与plc通讯之间的问题(vb and Communications plc)

程序是用stm32输出来的信号来控制继电器的开通与否，继而来控制电机的状态(Program is with stm32 output signal to control the opening of relay or not, and then to control the state of the motor )
