Library Description

Library contains functions for getting states of INT and AN pins Library contains functions for register read and write Library contains functions for setting temperature high and low interrupt thresholds for internal diode and external diodes Library contains functions getting temperature readings on internal diode and external diodes Library contains function for setting temperature range Library contains function for basic device configuration.

Key functions:

• uint8_t remotetemp_setRange( uint8_t range_setting ) - sets temperature range (( from 0 to 127 ) or ( from (-64) to 191 )).
• float remotetemp_getInternalDiode(void) - reads internal diode registers and calculates temperature value.
• float remotetemp_getExternalDiode( uint8_t diode ) - reads external diode registers and calculates temperature value.

Examples description

The application is composed of three sections :

• System Initialization - Initializes INT, AND pins, I2C and LOG
• Application Initialization - Initializes I2C driver, sets range, configures device and sets threshold values
• Application Task - Executes all 'remotetemp_aux_getXxx()' functions

void applicationTask( )
{
    remotetemp_aux_getFault( );
    remotetemp_aux_getHighLimitStatus( );
    remotetemp_aux_getLowLimitStatus( );
    remotetemp_aux_getThermLimitStatus( );
    remotetemp_aux_getHottestStatus( );
    Delay_ms(500);
}

Additional Functions :

• remotetemp_aux_getFault( ) - Reads external diode fault register, parses data to get which external diode is in fault and logs that diode
• remotetemp_aux_getHighLimitStatus( ) - Reads high limit status register, parses data to get which diode crossed high threshold and logs that diode temperature
• remotetemp_aux_getLowLimitStatus( ) - Reads low limit status register, parses data to get which diode crossed low threshold and logs that diode temperature
• remotetemp_aux_getThermLimitStatus( ) - Reads therm limit status register, parses data to get which diode crossed therm threshold and logs that diode temperature
• remotetemp_aux_getHottestStatus( ) - Reads hottest status register, parses data to get hottest diode and logs hottest diode temperature

• I2C
• UART
• Conversions

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.
