Defines
- #define MPL115A2_NUM_VARIABLES = 2
- Sensor::
_numReturnedValues; the MPL115A2 can report 2 values. - #define MPL115A2_INC_CALC_VARIABLES = 0
- Sensor::
_incCalcValues; we don't calculate any additional values.
Sensor Timing
The sensor timing for a Freescale MPL115A2
- #define MPL115A2_WARM_UP_TIME_MS = 6
- Sensor::
_warmUpTime_ms; the MPL115A2 takes about 6 ms to respond. - #define MPL115A2_STABILIZATION_TIME_MS = 0
- Sensor::
_stabilizationTime_ms; the MPL115A2 is stable as soon as it warms up (0ms stabilization). - #define MPL115A2_MEASUREMENT_TIME_MS = 3
- Sensor::
_measurementTime_ms; the MPL115A2 takes 3ms to complete a measurement.
Temperature
The temperature variable from a Freescale MPL115A2
- Range is -20°C to 85°C
- Accuracy is not specified on the sensor datasheet
Construct a new FreescaleMPL115A2_
FreescaleMPL115A2_Temp(FreescaleMPL115A2* parentSense,
const char* uuid = "",
const char* varCode = MPL115A2_
Parameters
parentSense
The parent FreescaleMPL115A2 providing the result values.
uuid
A universally unique identifier (UUID or GUID) for the variable; optional with the default value of an empty string.
varCode
A short code to help identify the variable in files; optional with a default value of "FreescaleMPL115A2_Temp".
- #define MPL115A2_TEMP_RESOLUTION = 2
