Hello,
How would I use the additional I2C busses on the Teensy 4.0, without something like the i2c_t3 library I'd been using with the T3.6? I don't know how to avoid being limited to SCA/SDL 0. The T4.0 has several sets of I2C, is it possible to use them at this point?
Worst case, I will have to try running everything off 1 I2C bus and use a multiplexer if I run into overlapping addresses. Was hoping not to though, I've got a couple of sensors that probably each utilize most of the bandwidth of a bus on their own and I've (foolishly) done a complete rebuild of a huge project using the 4.0... kicking myself for not having checked up on compatibility first, whoops...
