Library Description
Initializes GPIO driver and click driver functions, which detect a touch on determined pins. For more details, check the documentation.
Key functions
uint8_t capextend3_Touch_0()- The function reads a state of the AN pin.
uint8_t capextend3_Touch_1()- The function reads a state of the RST pin.
uint8_t capextend3_Touch_2()- The function reads a state of the CS pin.
uint8_t capextend3_Touch_3()- The function reads a state of the INT pin.
uint8_t capextend3_Touch_4()- The function reads a state of the PWM pin.
Examples Description
The demo application is composed of three sections:
void applicationTask()
{
touch_1 = capextend3_Touch_1();
touch_0 = capextend3_Touch_0();
touch_3 = capextend3_Touch_3();
touch_4 = capextend3_Touch_4();
if( touch_0 == 0 )
mikrobus_logWrite("Touch 0 ",_LOG_LINE);
if( touch_1 == 0 )
mikrobus_logWrite("Touch 1 ",_LOG_LINE);
if( touch_3 == 0 )
mikrobus_logWrite("Touch 3 ",_LOG_LINE);
if( touch_4 == 0 )
mikrobus_logWrite("Touch 4 ",_LOG_LINE);
Delay_ms( 100 );
}

Additional notes and information
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.
