    I'm not sure what else to suggest. Other displays I've used generally scale with transmit speed (but they were graphical, so I2C was the bottleneck for moving frame data). Perhaps that display has a processor that...

    It's an interesting idea, but I suspect it is a bit more complex than it seems. On the Slave end, the code would run as part of the ISR. The code you show has elements that seem right, but overall it seems off. It...

    Thanks for the feedback. I'll probably investigate it, but I have no idea when I could get something out.

    I don't quite follow your question. On Master-side the resetBus function will take I2C off the pins for a moment, manually send some clocks down SCL to release any stuck slaves, and then reconnect I2C. In this case...

    You'll have to supply a link to your library you are using. Other than that it is guessing. Using google I can see a DigoleSerial.h lib at: https://github.com/phalpern/Thermostat/blob/master/DigoleSerial.h That...

    It depends. Mostly any speedup will depend on the slave device and if it will respond well to faster than normal I2C speeds. I've gotten faster than normal communication working on something like a SSD1306 I2C display...

    Also to anyone following this thread - in regards to Teensy4: I was offered a T4 beta board back when it started, but I could not accept as I did not have the requisite time to work on a library port. I have now...

    This thread is still correct for problems involving this library. I am unfamiliar with DigoleSerialDisp library. It may work by simply swapping the include line: #include <i2c_t3.h> instead of #include...
