Library Description

Library provides functions for communication via UART module, and a function for controlling cs pin, which sets device mode.

Key functions:

• void canfd3_write_byte ( uint8_t input ) - Writes single byte of data
• uint8_t canfd3_read_byte( ) - Reads single byte of data
• uint8_t canfd3_byte_ready ( ) - Checks if new data ic received
• void canfd3_set_cs_pin ( uint8_t mode ) - Sets state of the CS pin

Examples description

The application is composed of three sections :

• System Initialization - Intializes UART module
• Application Initialization - Driver intialization
• Application Task - Choose one mode (read or write) of task. If you reading it checks if data is ready to be read and then reads one byte and if you are wiriting send data via UART.

void application_task ( )
{
    float read_data;
    char txt_out[ 30 ];

    read_data = thermo17_read_temp( THERMO17_TEMPERATURE_LOCAL );
    FloatToStr( read_data, txt_out );
    mikrobus_logWrite( " - LOCAL: ", _LOG_TEXT );
    mikrobus_logWrite( txt_out, _LOG_LINE );

    Delay_ms( 100 );

    read_data = thermo17_read_temp( THERMO17_TEMPERATURE_REMOTE );
    FloatToStr( read_data, txt_out );
    mikrobus_logWrite( " - REMOTE: ", _LOG_TEXT );
    mikrobus_logWrite( txt_out, _LOG_LINE );
    
    Delay_ms( 100 );
    mikrobus_logWrite( " ******************** ", _LOG_LINE );
    Delay_ms( 1000 );
}

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.
