Library Description

Initializes and defines GPIO driver and driver's functions. This function determines in which mode Cap Touch will works. The click can use a PWM library for setting the click in sync mode. Driver library also checks OUT pin state.

Key functions:

void captouch_setFastMode(void);- Function sets fast mode void captouch_setLowPowerMode(void);- Function sets low power mode uint8_t captouch_getOut(void);- Function gets state of OUT pin

Examples Description The demo application is composed of three sections:

• System Initialization - Initializes peripherals and pins.
• Application Initialization - Initializes click driver.
• Application Task - Sets the click on fast mode or low power mode and detects changes on OUT pin. The click also can go to sync mode by using a PWM library. By using a PWM library we can set period of PWM timer.

void applicationTask()
{
    uint8_t out = 0;

    captouch_setFastMode();

    //captouch_setLowPowerMode();

    out = captouch_getOut();

    if (out != 0)
    {
        mikrobus_logWrite( "Touch detected", _LOG_LINE );
    }
}

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.
