TouchKey 2 click has four capacitive pads powered by ATtiny817 which has an integrated touch QTouch® controller. The click is designed to run on a 3.3V power supply. The four LEDs onboard the click indicate the Key (Pad) is pressed. TouchKey 2 click communicates with the target microcontroller over UART and SPI interface.

Library Description

Defines and initializes driver's UART bus. Declares and defines driver's functions for sending and receiving data bytes, also for checking if data byte ready for reading. It also offers set, clear reset pin and target reset functions.

Key functions:

  • uint8_t touchkey2_readByte() - Read received byte.
  • uint8_t touchkey2_byteReady() - Checks is there a new byte received.
  • void touchkey2_targetReset() - Function is used to reset the device.

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes UART and LOG structures and sets CS as output.
  • Application Initialization - Initalizes UART driver and makes an initial log.
  • Application Task - (code snippet) Checks if new data byte have received in rx buffer (ready for reading), and if ready than reads one byte from rx buffer, that show if and what key is pressed.
void applicationTask( )
{
    char tmp;
    uint8_t rdyFlag;

    rdyFlag = touchkey2_byteReady();

    if (1 == rdyFlag)
    {
    tmp = touchkey2_readByte();
        if( tmp == 0x00 )
        {
            mikrobus_logWrite( "   Key released   ", _LOG_LINE );
            mikrobus_logWrite( "-------------------", _LOG_LINE );
        }
        else if( tmp == 0x01 )
        {
            mikrobus_logWrite( "   Key A pressed", _LOG_LINE );
            mikrobus_logWrite( "-------------------", _LOG_LINE );
        }
        else if( tmp == 0x02 )
        {
            mikrobus_logWrite( "   Key B pressed", _LOG_LINE );
            mikrobus_logWrite( "-------------------", _LOG_LINE );
        }
        else if( tmp == 0x04 )
        {
            mikrobus_logWrite( "   Key C pressed", _LOG_LINE );
            mikrobus_logWrite( "-------------------", _LOG_LINE );
        }
        else if( tmp == 0x08 )
        {
            mikrobus_logWrite( "   Key D pressed", _LOG_LINE );
            mikrobus_logWrite( "-------------------", _LOG_LINE );
        }
        else
        {
            mikrobus_logWrite( "   Error!!!   ", _LOG_LINE );
            touchkey2_targetReset();
}

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.
