Library Description

Library caries functions for sending and receiving data bytes, also for checking if the data byte is ready for reading.

void ata663254_enable(uint8_t state) - Function enables and disables click

void ata663254_writeByte(uint8_t input) - Function writes (sends) one byte in the RX buffer

uint8_t ata663254_readByte() - Function reads (receives) one byte from the RX buffer

uint8_t ata663254_ready() - Function checks is new data placed in the RX buffer

uint8_t ata663254_getRstState() - Function checks RST pin if undervoltage detection happens

Examples Description

• System Initialization - Initializes peripherals and pins
• Application Initialization - Initializes click driver
• The receiver part of the task logs each received byte to the UART bus, used for data logging. Transmitter part of the task sends a message every two seconds.

void applicationTask()
{
// RECEIVER
#ifdef __RX__
   if(ata663254_ready())
   {
       tmp = ata663254_readByte();
       mikrobus_logWrite(&tmp, _LOG_BYTE);
   }
#endif

// TRANSMITER
#ifdef __TX__
   uint8_t cnt;
   for (cnt = 0; cnt < 9; cnt++)
   {
       ata663254_writeByte(MESSAGE_DATA[cnt]);
   }
   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.
