Abstract: In this paper have designed a Multifunctional Teaching and Learning Experiment Board which is based on AT89C51, and the main control module of the boaed provides the Experimental basic functions of 51 Series SCM, such as the Lantern experimental, keyboard input, digital clock, DS1302 real-time clock, LCD, A / D conversion, D / A conversion, lattice and voice experiment. The hardware design and software debugging of the Experiment Board have already been completed in the laboratory .
This board is programmable in system, and the resources can be reused, operation is simple and convenient. This board fits the SCM teaching practice, and meets the various experiment requirements of different classes of the SCM enthusiasts and developer in different periods.
