Overview
Das TouchPad Click Board™ ist ein kapazitives Touch-Eingabegerät, das vom stromsparenden MTCH6102-Controller von Microchip gesteuert wird. Die Touchpad-Oberfläche ist mit einer schwarzen Kunststofffolie bedeckt, um zu demonstrieren, dass der Chip Deckschichten unterstützt (bis zu 3 mm für Kunststoff, 5 mm für Glas).
IC/Module: MTCH6102 Capacitive Touch Controller
The MTCH6102 is a low-power projected capacitive touch controller that supports taps, doubletaps, swipes and scrolling gestures using up to 15 channels. It has a small capacitive surface covered with a thin matte plastic layer that demonstrates cover layer support. This cost-effective application provides a flexible touch-sensing solution to optimize common constraints of size, power and cost.
Communication Interface: I2C
Touchpad Click Board™ uses a standard register-based read/write I2C protocol, similar to many other devices such as temperature sensors and serial EEPROMs, for communication with the target board microcontroller. The sensor also provides an open-collector active-low Interrupt pin (INT) that will be asserted any time new data is available.
Power Management
MTCH6102 aboard touchpad Click Board™ also includes power-saving features, such as a configurable sleep/idle frame rates, as well as a separate standby (<500nA) and active (<12 uA) mode.
