THE CONTROLLING DEVICE OF SINGLE-CHIP MICRO-COMPUTER FOR BOXCAR'S OUTPUT

This article introduces the method and principle of Boxcar's output under the control of a single-chip micro-computer. Moreover, the article offers a detailed picture of the hardware frame diagram and the software folw diagram in the controlling device of such a Single-Chip Micro-computer. The waveform generated by Boxcar has such a long circle that generally speaking,it is impossible for ordinary oscilloscope to display it. By using the controlling device, however, the waveform can be easily displayed on an ordinary ossilloscope. This controlling device helps achieve the goal of sampling, processing and displaying simutaneously; furthermore, it simulates every function of X-Y recorder. It is economical,small in volume, and convenient in operation. This is the up-to-date method in displaying the waveform by Boxcar,and is very popular in today's teaching experiments and scientific researches.
