Single chip microcomputer technology and CPLD technology has become the necessary professional knowledge of electronic class for students in Colleges and universities. The experimental board combined with curriculum content of college students selected AT89S52 microcontroller and Altera company production EPM7128SLC84-6. which are commonly used in the current school teaching. And it designs the common used digital tube display, 1602A LCD display, keyboard, and calendar clock interface circuit. Through a large number of examples of learning, students can quickly grasp the microcontroller C language and HDL Verilog programming skills in a short period of time.
