Library Description

Library performs IR and temperature measurement. The sensor gets an IR picture of the detected object (body) and measures ambient temperature, compares that two measurements and shows the IR picture as a 16x4 matrix. For more details check the documentation.

Key functions:

• void usbuart3_writeByte(uint8_t input) - Write Single Byte.
• uint8_t usbuart3_readByte() - Read Single Byte.
• uint8_t usbuart3_byteReady() - Check for the 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 received in the RX buffer (ready for reading), and if ready than reads one byte from the RX buffer. In the second case, the application task writes the message data via UART.

void applicationTask()
{
 char tmp;
 uint8_t rdyFlag;

// RECEIVER - UART polling 

 rdyFlag = usbuart3_byteReady();

 if (1 == rdyFlag)
 {
 tmp = usbuart3_readByte();
 mikrobus_logWrite( &tmp, _LOG_BYTE );
 }

// TRANSMITER - TX each 2 sec

  for (tmp = 0; tmp < 9; tmp++)
 {
 usbuart3_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.
