    The 5us high/low is correct for 100kHz rate. 4.7k is a good value. It really looks like Slave clock stretching, but that is quite a long duration. I'm not sure why it would not respond to some commands. If you have...

    Those delays should not be caused by the Master. Ignoring the SCL delay, when the bytes transmit, what is the SCL toggle speed? That would be the Master-side clock. I'm not sure why the hold times with SCL low...

    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...
