Maqueen Plus V1.0 I2C initialization issue
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
I am running a Maqueen Plus V1.0 with Micro_bit rev 2.21 (firmware vers. 256 or 257) and getting some trouble communicating with the hardware.
After a little troubleshooting with the debugger, it appear the block “Initialize I2C until success” systematically returns an “X” sign on the micro:bit display. It seems to be incapable of opening up the I2C communication line.
We have used these robots for nearly a year and never faced this situation before. We tried multiple computers, multiple micro:bit boards (all vers 2.2 or newer) and unfortunately this is a systematic error.
We also tried to upload different programs on the same micro:bits and they all work flawlessly. Only the “initialize I2C until success” block seems to be causing an issue.
For your reference, here is the makecode version we used:
makecode.microbit.org version: 6.0.8
Microsoft MakeCode version: 9.0.6
microbit runtime version: v2.2.0-rc6
codal-microbit-v2 runtime version: v0.2.55
Did anyone else face this situation?
Thanks
It's might be you are using the wrong library.
