Re: MLX90640 not found when running MLX90640_simpletest

Post by alixdujardin »

Hello, I follwed this protocol instead to try to connect the waveshare camera to the pybadge adafruit: https://learn.adafruit.com/adafruit-mlx ... mal-camera

One of the lines in the example code is "i2c = busio.I2C(board.SCL, board.SDA, frequency=800000)" but I am not using pins. Do you know what can I use to replace it?
thanks

Is that because these need to be connected?

board.SCL and board.SDA are the pins on the STEMMA connector:

Oh I see, do you have any idea why the code doesn't recognize the connectors then?

Not sure what's meant by not recognizing the connector. If it's an issue talking to the MLX90640, then it may be something else? Same as with the Arduino library, it may not work with that breakout.

Well I tried to run circuitpython_I2C_Scan, and I have a problem with the SCL and SDA connector it's said, "verify your wires," but it is solder so I am not sure what the problem is

Does that breakout include pull up resistors on the SCL/SDA lines?
