Don’t we just have egg on our face!
Yes within PiicoDev_Unified.py we were using the default I2C initialiser as found in the Raspberry Pi Pico MicroPython SDK document:
I’ve updated PiicoDev_Unified.py to set the I2C parameters explicitly and all appears to work well with Pico W. (commit 34940db)
Thanks for setting us on the right path @jimmo
