Library Description

The library initializes and defines the I2C bus driver and drivers that offer a choice for read data form register. The library includes function for read Temperature data and function for read and set temperature hysteresis and limit. The user also has the function for configuration chip and read Interrupt (INT pin) state.

Key functions:

• void enocean3_response_handler_set( void ( *handler )( T_enocean3_packet*, uint16_t* ) ) - Function sets handler on the function that should be performed.
• void enocean3_uart_isr( void ) - Function reads every single byte from the device, performs a crc8 check for header and data packet and makes a received response.
• uint8_t enocean3_sendPacket( T_enocean3_packet *packet ) - Function sends a packet data to the device by using UART interface.

Examples description

The application is composed of three sections :

• System Initialization - Initializes peripherals and pins.
• Application Initialization - Initializes UART interface and interrupt.
• Application Task - (code snippet) - Always checks does response packet ready, and if is ready calls a function to get response packet and makes a decide what will be performed, depending on the received response.

void applicationTask()
{
    checkResponse();
}

Additional Functions :

• makeResponse - Gets a response packet from the driver.
• logResponse - Shows a data packet to the uart terminal.
• logExample - Shows which button is pressed to the uart terminal.
• checkResponse - Checks does response ready or not.
• interrupt - To get a response from the device.

Other mikroE Libraries used in the example:

• Conversions
• UART

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.
