Library Description

Library contains basinc functions for working with the click board.

Key functions:

• void uarti2cspi_init(uint16_t baud) - Function for initializing the click board.
• uint8_t uarti2cspi_uartRead() - Function for reading a character.
• void uarti2cspi_uartWrite(uint8_t wByte) - Fucntion for writing a character.

Examples description

The application is composed of the three sections :

• System Initialization - Initialize the GPIO and communication structures.
• Application Initialization - Initialize the communication interface and configure the click board.
• Application Task - Character data is sent trough the UART interface of the click board. When all of the data has been sent the echo example is started.

void applicationTask()
{
    uint16_t counter_var;
    char text[5];


    for(counter_var=0;counter_var<10;counter_var++)
    {
        WordToStr(counter_var,&text[0]);
        Ltrim(&text[0]);
        uarti2cspi_serialWrite(&text[0],_LINE_PRINT);
    }

    uarti2cspi_serialWrite(&str1[0],_LINE_PRINT);
    uarti2cspi_serialWrite(&str2[0],_LINE_PRINT);
    uarti2cspi_uartWrite(0x00);

    while(1)
    {
        uarti2cspi_uartWrite(uarti2cspi_uartRead());
    }
}

Additional Functions :

All additional functions such as timer initialization and default handler.

Other mikroE Libraries used in the example:

• Conversions
• C_String
• SPI
• I2C
• 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.
