Abstract：In this paper,a design scheme of digital control DC constant current source system based on microcomputer control is presented.Using 32 bit STM32 as a microcontroller, equipped with keyboard in-put module,D/A conversion module,constant current source module,A/D acquisition module,LCD mod-ule to build up the whole system.Through the hardware system test,the system can realize the simple hu-man-computer interaction and communication,in the range of the range,the constant current source sys-tem has the function of stepping add and subtraction,can set the output current,and the output of the sys-tem is stable,the error is small, the precision is high, with the load capacity is strong.
