Library description
The library contains functions that perform UART reading, writing and UART rx buffer checking.
Key functions:
void irda3_writeByte(uint8_t input); - Function writes (sends) one byte to the UART RX buffer
uint8_t irda3_readByte(); - Function reads (receives) one byte from the UART RX buffer
uint8_t irda3_byteReady(); - Function checks state of the RX buffer (new data is placed in)
void irda3_reset(); - Function resets the and sets back in normal operating mode
Example description
void applicationTask() { uint8_t tmp; uint8_t rdyFlag; // RECEIVER - UART polling #ifdef __RX__ rdyFlag = irda3_byteReady(); if (1 == rdyFlag) { tmp = irda3_readByte(); mikrobus_logWrite( &tmp, _LOG_BYTE ); } #endif // TRANSMITER - TX each 2 sec #ifdef __TX__ for (tmp = 0; tmp < 9; tmp++) { irda3_writeByte( MESSAGE_DATA[tmp] ); mikrobus_logWrite( "MESSAGE SENT", _LOG_LINE ); } Delay_ms(2000); #endif }
Additional notes and information
Depending on the development board you are using, you may need USB UART click, USB UART 2 clickor 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.
