System and method for combining microcontroller chip and touch input to generate hardware events

Abstract

The invention discloses a system and method for generating hardware events by combining a microcontroller chip and a touch input. The system includes a touch detection module, a logic control module and a hardware event processing module. The touch detection module is used to detect multiple touch input channels the current touch state, and output the corresponding touch state information to the logic control module; the logic control module is used to judge whether the touch state information matches the preset touch state information, and if so, output a trigger signal to the A hardware event processing module; the hardware event processing module is used to trigger a hardware event corresponding to the touch state information according to the trigger signal, so that the touch information combination of multiple touch input channels directly triggers a hardware event, and is determined by the hardware The module runs independently to complete the occurrence of hardware events, which can effectively simplify the code logic and reduce the space occupied by the code.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a system and a method for combining a microcontroller chip and a touch input to generate hardware events. Background technique [0002] With the continuous development of MCU technology, MCU manufacturers usually try to improve the utilization of MCU external pins in order to improve the cost performance of MCU. For example, using the reset pin and debugging / programming pin of the MCU as a general-purpose input / output pin or as a function pin of a certain peripheral can make the MCU cost basically unchanged while the package remains unchanged. Competent for more and more complex tasks. [0003] Once the reset and debugging / programming pins are occupied, it will bring some other problems, the most obvious is to make the MCU lose the ability to update the program or make the program update more complicated: if you want to update the program, you need to reserve it at t...

Problems solved by technology

[0003] Once the reset and debugging / programming pins are occupied, it will bring some other problems, the most obvious is to make the MCU lose the ability to update the program or make the program update more complicated: if you want to update the program, you need to reserve it at the beginning of the software in advance. The time can be debugged, and the MCU can be reset by re-powering or software reset, which will increase the occupation of the program storage area and increase the logic complexity of the code
