LCD1602底层驱动,C语言编写 ，

1720的经典程序，实现了1720的几乎所有功能，程序编写标准-1720 classic procedures, to achieve the 1720 almost all the functions, procedures for the preparation of standards

一个用来作软件仿真用的KEIL的程序，有仿真的过程-used as a software simulation of KEIL procedures and the process simulation

PCA捕获功能原程序代码,初学单片机有用,代码已运行过,能用.-PCA capture the original program code, beginner Singlechip useful, the code has been in operation, and can be used.

数码管的显示子程序，对于用PROTEUS来仿真的同志，可以尝试的玩一下-Digital tube display subroutine for simulation using PROTEUS to comrades, you can try to play like

MSP430 串口RS485 通信代码很详细-MSP430 serial RS485 communications code in great detail

基于ARM中LPC2131芯片编写的各种uart源程序！-LPC2131 chips based on ARM in the preparation of a variety of uart source code!

这是一套基于单片机的温湿度测量系统，里边附有设计的原理图，pcb图，以及烧写程序代码（keil c51编写的）。温湿度传感器使用的是dht11，性价比高。该系统除了能显示温湿度以外，还能设置温湿度报警阈值。设计的pcb板，小巧，使用。这是本人的毕业设计，有实物为依据，具有可操作性。-This is a single-chip microcomputer-based measuring system of temperature and humidity inside with schematic design, pcb plans, as well as the programmer code (keil c51 prepared). Temperature and humidity sensors are used dht11, cost-effective. Except that the system can display temperature and humidity outside, but also set the temperature and humidity alarm threshold. Pcb board design, compact, use. This is my graduation project, there is the physical basis of operational.
