    I added 4 mS delays after each and a longer one in the main loop.Only after adding a 300mS delay does the program get stable.Seems the display pulls the i2c bus low and never releases.

    How fast can the display respond to clear display cmd , home cmd, and fill 2 lines with text?

    I had tried 10K pullups but the signals did not look good.

    Interfacing to the display using i2c at 3.3V with 4.7K pullups.I have been able to send both lines multiple times butrandomly the i2c bus freezes. Seems as the data line is being pulled low.happens...
