Reads temperature from high accuracy temperature diode.
This function reads the temperature from the high-accuracy temperature diode The returned result contains 4 fractional bits. For example: 0x00000200 = +32.0000 degC 0x0000020C = +32.7500 degC 0xFFFFFEC3 = -19.8125 degC
- Warning
- This function uses the SoC ADC to measure the temperature. This function must not be called while the ADC driver is active, or the SoC ADC is open.
-
This function uses the internal test-bus (ATEST) to measure the temperature. The test-bus must not be used when calling this function.
- Note
- Due to long and repeated ADC sampling, this function takes roughly 8 milliseconds to execute.
- Returns
- Ambient temperature in degrees Celcius, with 4 fractional bits
