) |
Checks if a Si7013 is present on the I2C bus or not.
- Parameters
-
[in] i2c
The I2C peripheral to use (Not used). [in] addr
The I2C address to probe. [out] deviceId
Write device ID from SNB_3 if device responds. Pass in NULL to discard. Should be 0x0D for Si7013, 0x14 for Si7020 or 0x15 for Si7021
- Returns
- True if a Si70xx is detected, false otherwise.
