I2C2 now working on pico?

I actually have had problems doing this in the past with the BMP180 specifically; almost identical configuration actually, doublebuffered display and BMP180 on same I2C bus; sometimes the BMP180 just seemed to get pissed off and start holding the bus low. I kept thinking it was wiring - and sometimes it reacted as if it was - but there was also behavior I couldn't reconcile with a hardware explanation. Plus I didn't get accurate data from it when it was inside my device, while it worked fine on the bench. I eventually gave up and have it disconnected. Never did figure out why it would go off the rails like that, but it failed with 3 different BMP180's, but they'd all work fine when I tried to test on the bench, and it failed with three different wiring setups as well (2 home-made PCB's and before that with wires)
