电路图和程序是正确的。如果问题可以去我的博客吨..

这是一个用汇编写的8051单片机系统的小车避障程序，是用红外发射和接收的方式，并结合了proteus 6.7，相信对初学者有所帮助-This is a compilation was made with the 8051 System of Dolly obstacle avoidance procedures is the use of infrared transmitting and receiving the way, and coupled with a 6.7 lic sure to help beginners

本要求适用于Microcon-T02半导体冰箱控制板（以下简称控制板）。本控制板由电源板、显示控制板两部分组成。-The requirements apply to Microcon-T02 semiconductor refrigerator control panel (hereinafter referred to as the control panel). The control panel from the power supply board, display panel is composed of two parts.

单片机键盘描扫程序. 一直在用的程序.-SCM keyboard depiction sweep procedures. Have been used in the procedure.

1．熟悉硬件仿真工具KD30的使用。 2．修改样本程序 SAMP1a，使无论在计数或停止计数时，按 SW3 均对计数值清零，并停止计数。 3．编制一个秒表程序, 测试精度为0.1秒，按 SW1键启动计数，再按一次 SW1键停止计数。任何时候按 SW3 键停止计数，并对计数值清零。 4．按 SW1键后， 以 0.1 秒为单位开始计数，再按一次 SW1 键停止计数。若按 SW1 键时间超过2秒，则计数值清零，回到初始状态。-1. Familiar with the hardware simulation tool KD30 use. 2. Revised procedures SAMP1a samples, regardless of the count or counts at the end, according to SW3 numerical terms were right, reset, and stop counting. 3. Preparation of a stopwatch procedures, testing accuracy of 0.1 seconds, according to bond SW1 start counting, according to a key SW1 stopped counting. By SW3 any time to stop counting bond and reset the count. 4. By SW1 bond, after 0.1 seconds for start counting, according to a key SW1 stopped counting. If SW1 keys by the time more than two seconds, then reset the count and return to the initial state.
