Touchpad Click is a capacitive touch input device driven by Microchip’s low-powered MTCH6102 controller.
We provide a library for the Touchpad Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for Touchpad Click driver.
Config Object Initialization function.
void touchpad_cfg_setup ( touchpad_cfg_t *cfg );
Initialization function.
TOUCHPAD_RETVAL touchpad_init ( touchpad_t ctx, touchpad_cfg_t cfg );
Click Default Configuration function.
void touchpad_default_cfg ( touchpad_t *ctx );
Get touch coordinate
void touchpad_get_touch_coordinate ( touchpad_t ctx, touchpad_cord_t cord );
Get event state
uint8_t touchpad_get_event_state ( touchpad_t *ctx );
Gesture type
uint8_t touchpad_get_gesture_type ( touchpad_t *ctx );
Demo application shows reading of current event:
- touch event (Touch Coordinates)
- Gesture event (gesture type)
The demo application is composed of two sections :
Configuring clicks and log objects. Setting the Click in the default configuration.
void application_init ( void )
{
log_cfg_t log_cfg;
touchpad_cfg_t cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.

Additional notes and informations
Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
