Library Description

The library covers all the necessary functions that enables the usage of the RS232 SPI click board. User can send or receive data, check if data is ready or if tx line is busy, it is possible to change baud rate and to turn the device on or off.

Key functions:

  • uint8_t rs232spi_dataRead() - Function is used to read data from the receive register.
  • uint16_t rs232spi_dataReady() - Function is used to check if there is availavle data for reading.
  • void rs232spi_dataWrite( uint8_t wrData ) - Function is used to write into the transmit-buffer register.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes SPI and LOG structures, sets RST pin as output and INT pin as input.
  • Application Initialization - Initialization driver enables SPI, sets up the device and starts write log.
  • Application Task - (code snippet) This example demonstrates the use of RS232 SPI click board by sending or receveing the message.
void applicationTask()
{
    uint8_t tmp;
    char rec;
    uint8_t mode = RS232SPI_WRITE_MODE;

    if ( mode == RS232SPI_READ_MODE )
    {
        // RECEIVER - UART polling
        if ( rs232spi_dataReady() != 0 )
        {
            rec = rs232spi_transfer( _RS232SPI_CMD_READ_DATA );
            mikrobus_logWrite( &rec, _LOG_BYTE );
        }
    }
    else if ( mode == RS232SPI_WRITE_MODE )
    {
        // TRANSMITER - TX each 2 sec
        for ( tmp = 0; tmp < 9; tmp++ )
        {
            rs232spi_dataWrite( MESSAGE_DATA[ tmp ] );
            if ( tmp < 6 )
            {
                Delay_ms( 100 );
            }
        }
        Delay_ms( 2000 );
    }
}

  • SPI
  • UART

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.

DIGI POT 14 Click is a compact add-on board that contains a digitally controlled potentiometer. This board features the TPL0102, a dual-channel digital potentiometer with non-volatile memory from Texas Instruments. It is a 100K resistance end-to-end potentiometer with a 256-position resolution, where the wiper position can be stored in EEPROM. It can operate from both 3.3V and 5V power supplies and provides a typical 92ppm/ºC end-to-end nominal resistance temperature coefficient and only 4ppm/ºC ratiometric.
