Library Description
The library covers all the necessary functions to control RAQ Click board™. Library performs a standard I2C interface communication.
Key functions:
( uint8_t *cfg_data, uint8_t *prod_data, uint16_t *pid )
- Get sensor info function.( uint16_t *mox_lr, uint16_t *mox_er )
- Initialization of the sensor function.( float *rmox, uint16_t mox_lr, uint16_t mox_er )
- -.Examples description
The application is composed of three sections :
void application_task ( )
{
ret = raq_start_measurement( );
status_data = raq_get_status( );
Delay_ms( 10 );
while ( ( status_data & RAQ_STATUS_LAST_SEQ_STEP_MASK ) != RAQ_SUCCESS )
{
status_data = raq_get_status( );
Delay_ms( 10 );
}
ret = raq_read_rmox( &rmox, mox_lr, mox_er );
Delay_ms( 10 );
if ( ret == RAQ_SUCCESS )
{
FloatToStr( rmox / 1000, demo_log );
mikrobus_logWrite( " Rmox : ", _LOG_TEXT );
mikrobus_logWrite( demo_log, _LOG_TEXT );
mikrobus_logWrite( " kOhm", _LOG_LINE );
mikrobus_logWrite( "-------------------------", _LOG_LINE );
Delay_ms( 2000 );
}
else
{
display_error( );
}
}

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.
