利用 AT89S51 单片机的 P0 端口的 P0.0 － P0.7 连接到一个共阴数码管的 a － h 的笔段上，数码管的公共端接地。在数码管上循环显示 0 － 9 数字，时间间隔 0.2 秒。 -use AT89S51 SCM P0 port of P0.0- P0.7 connected to a digital control Yam were a-h of the pen, digital tube connected to the public. The digital display tube cycle 0-9 figures, the time interval of 0.2 seconds.

C8051f020是基于51核的业界8位单片机最高速的，指令执行速度25MIPS。这个程序包是新华龙公司提供的，需要购买900元的开发系统才会赠送此文件包，先上传。可以用keil软件打开或者去www.xhl.com.cn下载IDE软件打开工程ps－－－c文件直接用记事本就ok啦^_^，里面有温度传感，步进电机等等源代码，方面移植！^_^-C8051f020 is based on the 51 nuclear industry eight most high-speed microcontroller, instruction execution speed MIPs. This package is a new company providing the Hualong, you need to buy 900 yuan development system will give this package, the first upload. Keil software can be used to open or download IDE www.xhl.com.cn open software engineering-- c ps documents directly on the notebook ok-- ^ _ ^, inside temperature sensor, stepper motors, etc. source code, area transplant! ^ _ ^
