In the paper,a single line simulator for a 8051 MCU with OCDS online simulation hardware module,using Manchester coding.The simulator uses STM32 processor and peripheral circuits to form the circuit board,and then the STM32 is programmed to realize the software function of the simulator.The emulator is responsible for converting the debugging command sent by the host USB into a single line protocol,and then sending it to the OCDS of MCU to control the operation of MCU.The simulator can implement software code download,start and stop,breakpoint setting,single step execution and storage access to MCU.The single line simulator also has certain reference value for other types of simulators.
Key words
