Retcode_T LightSensor_configureThresholdInterrupt (LightSensor_HandlePtr_T handle, uint32_t upperThreshold, uint32_t lowerThreshold, uint32_t thresholdTimer)
 function responsible to set interrupt conditions, that means, threshold boundaries and threshold timer for lightsensor interrupt. Interrupt will be fired if the light intensity is crossed threshold boundaries for a window period defined in threshold timer.User must register the callback before calling configuring interrupt More...
Retcode_T LightSensor_deInit (LightSensor_HandlePtr_T handle)
 DeInitializes the light sensor referenced by the passed handle. More...
Retcode_T LightSensor_disableInterrupt (LightSensor_HandlePtr_T handle)
 Disable Interrupt type on the handle. More...
Retcode_T LightSensor_getInterruptStatus (LightSensor_HandlePtr_T handle, LightSensor_ConfigInterruptPtr_T interruptStatus)
 function to read light sensor interrupt status register More...
Retcode_T LightSensor_init (LightSensor_HandlePtr_T handle)
 Initializes the LightSensor referenced by the passed handle. More...
Retcode_T LightSensor_readLuxData (LightSensor_HandlePtr_T handle, uint32_t *luxData)
 function to read sensor data in milli lux. More...
Retcode_T LightSensor_readRawData (LightSensor_HandlePtr_T handle, uint16_t *luxData)
 Reads raw sensor data from light sensor referenced by the passed handle. More...
Retcode_T LightSensor_registerDeferredCallback (LightSensor_HandlePtr_T handle, deferredInterruptCallback deferredCallback)
 function responsible to register deferred interrupt handler for light sensor. When user registers deferred callback their callback will be executed in timer daemon context, where there is no restriction of using delay functions and/or APIs related to bus access. More...
Retcode_T LightSensor_registerRealTimeCallback (LightSensor_HandlePtr_T handle, interruptCallback realTimeCallback)
 function responsible to register real time interrupt handler for light sensor. When user registers real time callback their callback will be executed in ISR context. User must not use any delay functions or bus access in ISR context. More...
Retcode_T LightSensor_setBrightness (LightSensor_HandlePtr_T handle, LightSensor_ConfigBrightness_T brightness)
 function to set brightness to low or high for light sensor More...
Retcode_T LightSensor_setContinuousMode (LightSensor_HandlePtr_T handle, LightSensor_ConfigMode_T manualMode)
 Function to enable/disable the Continuous mode for the light sensor referenced by the passed handle. More...
Retcode_T LightSensor_setIntegrationTime (LightSensor_HandlePtr_T handle, LightSensor_IntegrationTime_T integrationTime)
 function to configure integration time of light sensor. More...
Retcode_T LightSensor_setManualMode (LightSensor_HandlePtr_T handle, LightSensor_ConfigMode_T manualMode)
 Function to enable/disable the Manual mode for the light sensor referenced by the passed handle. More...

static void maxIsrCallback (uint32_t channel, uint32_t edge)
 MAX44009 driver callback function that will be called during ISR. More...
