The paper introduces an application method based on Proteus MCU simulation. A high reliable microcontroller AT89C51 is used as the core control chip in the digital controlled direct current voltage-stabilized source. The system is composed of the ADC0832 chip of dual-channel AD transformation with 8 bits resolution, the current output type 8 bits DA converter, the current amplification module circuit and the display module circuit, The simulation process of the digital controlled direct current voltage-stabilized source is successfully realized by Proteus software. The simulation result shows that the program debugging on the target hardware can be greatly simplified by using Proteus software.
