bool b_temperature_init ( void  )
eExecStatus e_temperature_get_config ( signed portCHAR **  ppcStringReply)

Get the temperature sensor config.

Parameters
ppcStringReplyInput/Output. The response string. NEVER NULL AS INPUT. A malloc for the response string is performed here; the caller must free this string.
Returns
the status of the command execution.

Set the sensor config.

Parameters
ppcStringReplyInput/Output. The response string. NEVER NULL AS INPUT.
acInput. Number of args
avInput. pointer to args
Returns
the status of the command execution.

The following table give the correspondance between the ADC code and the temperature Each elements of the table corresponds to an ADC code value.

The index in the table give the corresponding temperature (inC) with the following formula : Tempeature=index-20. table[O] corresponds to -20C temperature code The following table gives the ADC code for VCC=3.3V and Aref=AVcc
