Dev_Temp_Get_ADC_Sample()

void Dev_Temp_Get_ADC_Sample

(

)

Returns

void

This function gets the temperature ADC sample and adds it to the temperature buffer for averaging use.

< store last 128 values and then average

< flag to monitor if full then do averaging.

Dev_Temp_Get_Temperature_Celcius()

int8_t Dev_Temp_Get_Temperature_Celcius

(

void

)

Returns

void

This function takes in the current adc values and get the closest high temperature value in the lookup table. i.e. if the averaged value is 3195, it will return the temperature value corresponding to 3079 i.e. 65. This value is offset by 40 degrees to avoid working with negative.
