Description:
These registers store the most recent temperature sensor measurement.
Temperature measurements are written to these registers at the Sample Rate as defined in Register
25.
These temperature measurement registers, along with the accelerometer measurement registers,
gyroscope measurement registers, and external sensor data registers, are composed of two sets of
registers: an internal register set and a user-facing read register set.
The data within the temperature sensor’s internal register set is always updated at the Sample Rate.
Meanwhile, the user-facing read register set duplicates the internal register set’s data values
whenever the serial interface is idle. This guarantees that a burst read of sensor registers will read
measurements from the same sampling instant. Note that if burst reads are not used, the user is
responsible for ensuring a set of single byte reads correspond to a single sampling instant by
checking the Data Ready interrupt.
The scale factor and offset for the temperature sensor are found in the Electrical Specifications table
(Section 6.4 of the MPU-6000/MPU-6050 Product Specification document).
The temperature in degrees C for a given register value may be computed as:
Temperature in degrees C = (TEMP_OUT Register Value as a signed quantity)/340 + 36.53
Please note that the math in the above equation is in decimal.
Parameters:
TEMP_OUT 16-bit signed value.
Stores the most recent temperature sensor measurement.
