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.

IF I try to send cmds toclear,home, display 1 line , gotoline 2, displayfaster than 2 Hz the display hangs the i2c bus randomly.Is that expected?T

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.
