Description

Hello,

I'm using the Wire library.

I try to communicate between the arduino due and the VEML6030 of sparkfun via the pins SDA 20 and SCL 21. But when I write Wire.begin() and try to communicate in I2C via SDA 20 and SCL 21 between the VEML6030 and the arduino due I can't. The connections are fine and the VEML6030 and the arduino due are well powered.

Maybe there is an issue on the library for the arduino due to use SDA 20 and SCL 21.

Thanks for the help.

Research direction

Start at the Wire library's Wire.begin() entry point and trace how the Arduino Due selects SDA 20 and SCL 21. The report names no source files or tests, so first reproduce the VEML6030 communication failure and verify the pin initialization path. Done means confirming whether the library is responsible and, if so, adding a focused fix and regression coverage.
