基于51系列单片机的串口通信测试程序，希望对大家有帮助

八路电压表C程序 使用AT89C52单片机，12MHZ晶振，P0口读入AD值，P2口作AD控制，用共阳LED数码管 P1口输出段码，P3口扫描，最高位指示通道（0-7）。-Eight-way voltage meter C program using AT89C52 single-chip, 12MHZ crystal, P0 I read into the AD value, P2 I make AD control, with a total of P1 Yang LED digital tube output above code, P3 port scan, the maximum channel bit instructions (0-7).

一个实用的LED条型显示屏程序，采用PHLIPS P89C51RD2芯片，LED显示驱动板为1/16分扫。本程序已经成功应用于多种场合-A practical LED bar display procedures PHLIPS P89C51RD2 chip, LED display driver board for 1/16 sweep. This procedure has been successfully applied to many occasions

本程序用于用单片机控制步进电机的转动。用单片机的某一个引脚实现控制，如果引脚电平为高则实现正转，反之为反转。所用单片机为日立系列h83664十六位单片机。本代码使用c语言实现，开发环境为日立系列单片机专用开发环境-This procedure for the use of single-chip stepper motor rotation control. With a pin MCU control, if the pin level is higher then realize to the contrary, for the inversion. Used in single-chip for Hitachi Series 16 Singlechip h83664. This code uses the c language, development environment for the Hitachi series of single-chip dedicated development environment
