All;
Thanks for the help in advance, and thanks for providing such a coherent community around the Teensy boards.
So, I've been trying to make I2C work across two Teensy 3.2 boards. I've had sufficient trouble that I currently have it set up ONLY for I2C and will worry about the rest of the hardware when I've solved this roadblock.
Between the boards:
GND -> GND
18 -> 18 -> 3.9k ohm -> 3v3
19 -> 19 -> 3.9k ohm -> 3v3
I'm running the example code from both the stock Wire library and the Teensy specific one and can't get any communications between the boards. A few days ago I could get the examples to work, now not even that. In bone stock config.
The Teensys will happily blink their LEDs and accept firmware flashes. USB serial SEEMS to work fine, so far.
Thoughts on this? Has anyone experienced anything similar?
Many thanks
alex
