Abstract

The invention belongs to the field of circuit technology and provides a debugger applied to a microcontroller. The debugger comprises a debugging interface control module, a digital debugging module and a communication control module, wherein the digital debugging module and a digital function module of the microcontroller have the same structure, a debugging result obtained after debugging is performed on the digital debugging module and a debugging result obtained after debugging is performed on the digital function module of the microcontroller are the same, the communication control module performs communication with an analog function module in the microcontroller, and debugging on the analog function module in the microcontroller can be realized. In this way, by use of the debugger, debugging on the digital function module and the analog function module in the microcontroller can be realized, and the area of a microcontroller chip cannot be enlarged due to the fact that the debugger is located outside the microcontroller. As a result, by the adoption of the debugger, debugging on the analog function module and the digital function module of the microcontroller on the premise of not enlarging the area of the microcontroller chip is realized.

Description

technical field [0001] The invention belongs to the technical field of circuits, in particular to a debugger for microcontrollers. Background technique [0002] The microcontroller (Microcontroller Unit, MCU) debugger is a tool for users to debug applications when developing MCU-based applications. The MCU debugger can make the program run according to the user's wishes, such as single-step operation and full-speed operation. Or pause the operation (breakpoint) at a specified line of instruction, or obtain relevant information (such as status register information, program pointer, etc.) of the MCU during operation and upload it to the host computer for users to view. [0003] There are two implementation schemes for the existing MCU debugger. One is to integrate the debug interface control module into the MCU chip. Return to the host computer, but integrate the debugging interface control module into the MCU chip, which increases the area and cost of the MCU chip. Another ...
