Hi all,
I am running into some issues in getting a vl6180x time of flight sensor to work with teensy. I have tried both LC and 3.2, same non.result.
I have tried to use the i2c_t3 basic scanner, but it doesn't even get past the initialization phase - no serial output. The i2c scanner does work, but it cannot find any devices. I have hooked up another i2c device (i2c oled) and it correctly returns the address.
This leads me to think it is a connection issue with the vl6180x sensor. I haven't used pull-up resistors myself before, they were always onboard, and I think this is where my issue is at the moment. I have added a 2.2 kohm resistor between both sda and scl and 3.3v in my connection - similar to this diagram: https://www.google.fi/url?sa=i&rct=...aw2o_XKwQ4Wz59zaDxlNB619&ust=1535477121773010
I have tried 2 different vl6180x sensors, and with both I am running into the same issues so I don't think I have a faulty part.
Any idea where I need to look next?
Appreciate the help,
Bob
