Version 2.0.1: Examples do not work any more (i2c) #73

Closed moeskerv closed 4 years ago

moeskerv commented 4 years ago

Recent changes in the initialization of the sensor object results in non working examples:

If I get it right, the latest changed in the begin() method make the I2C addr and the wire object mandatory. As the examples do not provide them the connection to the BME280 will not get set up without further modification of the example.

bool Adafruit_BME280::begin(uint8_t addr, TwoWire *theWire)

BR, Volker

It was caused by this commit: https://github.com/adafruit/Adafruit_BME280_Library/commit/2a23df09f35986d1fb06a40f107051907ee53fcc

The parameters are not required. Defaults are provided in the header file: https://github.com/adafruit/Adafruit_BME280_Library/blob/master/Adafruit_BME280.h#L218

I just ran the bme280test example and it ran fine. What sketch are you running and how is the board wired?

moeskerv commented 4 years ago

Oh, yes. I have my BME280 wired to 0x76, the default is 0x77 so that is the reason. Thanks a lot for the feedback and sorry for the confusion!

So, all is fine! Have a good weekend.
