为了实现对本公司生产的基于单片机技术的单轴、I/O控制板的检测，设计了本测试程序。该测试程序采用PC机与单片机的通讯技术，来测试已焊接完成的控制板的各种功能，如步进电机控制、字符型LCD显示及I/O操作等功能。上位PC机测试程序采用VB编写、下位单片机采用C语言编写，从而使的对控制板的测试变的直观、简单、方便。-In order to realize the production of the company based on the uniaxial single-chip technology, I/O panel of the testing, design of the test procedure. The test procedures used PC machines with single-chip communications technology, to test the control panel has been welded to complete a variety of functions, such as stepper motor control, character LCD display and I/O operations functions. Host PC using VB test procedures for the preparation of the next-bit single chip using C language, so that on the control panel change the visual test, a simple and convenient.
