| Abstract: | The system is a basic system of single clip composed of 89C51 single clip, 373 data flip-latch and operating mode switch circuit. while the system is linked with PC and the down load program of PC is run, it controls operating mode, switches circuit switches the system to program state, and the system writer the new program code to 28F512 memory, so it has realized the programmable ability of the system. The system presents many advantages: low cost, easy design and more practicability etc. |
