Library Description
Library initializes and defines GPIO driver and performs control of device voltage.
For more details check the documentation.
Key functions:
- void rs485_writeByte(uint8_t input) - Write Single Byte.
- uint8_t rs485_readByte() - Read Single Byte.
- uint8_t ras485_byteReady() - Check for new byte received.
Example description
The application is composed of three sections:
- System Initialization - Initializes UART module.
- Application Initialization - Driver intialization.
- Application Task - (code snippet) - Checks if new data byte has been received in the RX buffer (ready for reading), and if it has then it reads one byte from the RX buffer. Otherwise, the application task writes the message data via UART.
void applicationTask()
{
char tmp;
uint8_t rdyFlag;
// RECEIVER - UART polling
rdyFlag = rs485_byteReady();
if (1 == rdyFlag)
{
tmp = rs485_readByte();
mikrobus_logWrite( &tmp, _LOG_BYTE );
}
// TRANSMITER - TX each 2 sec
/*
for (tmp = 0; tmp < 9; tmp++)
{
rs485_writeByte( MESSAGE_DATA[tmp] );
mikrobus_logWrite( "MESSAGE SENT", _LOG_LINE );
}
Delay_ms(2000);
*/
}

Additional notes and information
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.
