Abstract

The invention provides system debugging method and system of a positive-impedance converter (PIC) controller. The system debugging method of the PIC controller comprises the steps of: carrying out system programming on the PIC controller through a programming interface of the PIC controller to enable at least two interfaces of the PIC controller to be used as communication interfaces; and carrying out system debugging on the PIC controller through the communication interfaces of the PIC controller. The invention improves the interface utilization ratio of the PIC controller, reduces the required interface resources, and is beneficial to the popularization of debugging codes.

Description

technical field [0001] The invention relates to the field of single-chip microcomputer control, in particular to a system debugging method and system for a PIC controller (Peripheral Interface Controller, peripheral interface controller). Background technique [0002] All mid-range chips of PIC controllers provide in-system programming function, which can reduce a lot of development time and make products be launched to the market faster. The in-system programming function needs to be realized through two main lines and three auxiliary lines. Among them, the two main lines include the clock line (CLOCK) and the data line (DATA); the three auxiliary lines include the programming voltage line (Programming voltage), the power line ( POWER) and ground (GROUND). [0003] Microchip, the manufacturer of PIC controllers, provides emulators for programming interfaces through PIC controllers: programming clock interface (PGC), programming data interface (PGD), programming voltage int...
