气体传感器采样与无线数据传输并发送至电脑 cc2530,多通道数据传输，IAR版本为8.1(Gas sensor sampling and wireless data transmission and sent to the computer cc2530, multi-channel data transmission, IAR version 8.1)

上位机，与51单片机进行通信，将从单片机发送过来获得的信息显示在显示界面上。(PC, with 51 single-chip communication, sent from the information obtained from the microcontroller is displayed on the display screen.)

基于MSP430的PS2扫描抢扫描程序，PS2与单片机的通信(Based on MSP430 PS2 scanning grab scanner)

stm32f103c8t6上面实现uart3的Irda功能接受红外字符，控制TIM4上面4个通道的pwm输出占空比(stm32f103c8t6 functions to achieve the above uart3 acceptance of Irda Infrared character, control TIM4 above 4 channel pwm output duty)

基于51单片机的全自动洗衣机控制器，采用AT89C2051单片机(Mpu washing machine controller, using AT89C2051)

nrf905通信 基于rs232(nrf905 based RS232 communication)

本例程是基于KILE的AT89C52系统板的全套开发例程和相关外设的原理图，实物图。(This routine is based on the AT89C52 KILE complete development system board routines and related peripherals schematics, physical map)

a microcontroller as the core of the vegetable greenhouse temperature control system.

说明：  GD32 SPI 主从通信，通过片选IO启动传输，单次最大传输64K(GD32 SPI master-slave communication)

将每2片74595做级联，然后再将级联之后的所有时钟线与数据再并联在一起最后对每一组的锁存控制线做单独控制.(Application to do a project, the more I/O, applied to the 74,595 to do the extension, but you want to mount multi-chip 74595, is bound to have a lot to use the I/O port, in order to solve this problem, I will be every 2 sheet 74595 do cascade, and then cascade after all the clock line and the data in parallel and then together (i.e., all 74595 communal clock and data lines, it only occupies two I/O port lines) Finally, for each group latch control lines do individually controlled (equivalent to Chip Select), so that a hardware circuit by a great degree of simplification, both procedures can also share a driving subroutine 74595, to control the type of lock inventory control line, serial data is sent to the port 74595 cascade module. As a result of the hardware and software have a large degree of optimization.)
