Library Description
The library covers all the necessary functions to control Touchpad 3 Click board™. Library performs a standard I2C interface communication.
Key functions:
uint16_t *x_axis, uint16_t *y_axis
- Get touch data function.uint8_t offset_loc, uint8_t tx_data, uint8_t *p_response
- Write register data function.uint8_t offset_loc, uint8_t *read_data, uint8_t *p_response
- Read register data function.Examples description
The application is composed of three sections :
void application_task ( )
{
if ( touchpad3_get_int( ) == TOUCHPAD3_INT_STATUS_HIGH )
{
touchpad3_get_touch( &touch_data, &x_axis, &y_axis );
Delay_ms( 100 );
if ( ( touch_data.tch_state == TOUCHPAD3_STATE_TCH ) &&
( touch_data.touch_id == touch_id_state ) )
{
WordToStr( x_axis, log_text );
mikrobus_logWrite( " X Coordinate : ", _LOG_TEXT );
mikrobus_logWrite( log_text, _LOG_LINE );
WordToStr( y_axis, log_text );
mikrobus_logWrite( " Y Coordinate : ", _LOG_TEXT );
mikrobus_logWrite( log_text, _LOG_LINE );
mikrobus_logWrite( "------------------------------", _LOG_LINE );
Delay_ms( 100 );
}
}
}

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.
