Detailed Description

ADC10 sensors reading.

Reading of ADC10 sensors is done regularly and can be retrieved any time. The last registered value will be returned.

Function Documentation

void ADC10_ISR

(

)

ADC10 Interrupt Service Request.

The value read from the ADC10 is stored on a variable depending on the adc_currentState, and the corresponding flag of reading done is set. If adc_currentState is not a reading state, the ISR is ignored

Here is the caller graph for this function:

void adc_init

(

)

This function initializes the ADC variables.

The value of luminance sensor feed is set to 1, so it is turned on/off by the direction of the bit, in or out. All values and time stamps of readings are set to 0.

Here is the caller graph for this function:

UInt16 adc_proccess

(

)

This function processes the tasks of the ADC.

The tasks are based on the value of adc_currentState variable. On ech state a check is done, if state have to change, actions are executed and the state changes. The actions of each task on changing to the next are:

• ADC_S_IDLE: Charge ADC for temperature reading, set state to ADC_S_CHARGING_T;
• ADC_S_CHARGING_T: Enable conversion for temperature;
• ADC_S_READING_T: If temperature was read, charge ADC for Voltage, set state to ADC_S_CHARGING_V;
• ADC_S_CHARGING_V: Enable conversion for voltage;
• ADC_S_READING_V: If voltage was read, charge ADC for Voltage, set state to ADC_S_CHARGING_L;
• ADC_S_CHARGING_L: Enable conversion for luminescence;
• ADC_S_READING_L: If luminescence was read, charge ADC for Voltage, set state to ADC_S_IDLE.

The return value depends on current state, when state changes to charging for any sensor, the return value is 10ms, when it goes to IDLE, the return value is 955ms, all others are 5ms this gives 1s for each measurement cycle if no delay occurs and ADC10 stays read under 5ms after the reading is requested.

Returns

Time to run again (ms); 0 means 65536ms.
