Title:
TOUCH EVENT DETECTION METHOD, MCU, TOUCH CONTROL DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/081817
Kind Code:
A1
Abstract:
A touch event detection method, an MCU, a touch control device, and a storage medium. The MCU is connected to a touch key by means of N channels, and the touch key comprises N touch sub-keys. Said method comprises: according to the current voltages of N channels, determining whether there is a pressing operation currently on the touch key (S501); if there is a pressing operation currently on the touch key, determining the maximum voltage among the current voltages of the N channels, and determining a first channel having the maximum voltage (S502); and if the first channel has a second channel and a third channel which are adjacent thereto, determining a pressed position of the touch key according to the maximum voltage, the current voltage of the second channel, the current voltage of the third channel, and the positions of the touch sub-keys respectively corresponding to the first channel, the second channel, and the third channel (S503). In this way, the accuracy of the calculated pressed position is ensured.
