    Apologies if I have mis-understood the code. I am interested in using GET to read the characters codes back from a 2/4 line LCD display. Reading the source code I think I understand that this hasn't been implemented for LCD_IO type 10/12. I guess there may be some problem with setting the 8574 to read without resetting the LCD. Am I reading this correctly or should it be possible even if by directly writing I2C rather than GET? I have started to look at this route but woudl like to save the time if ithas already been done.

    Many Thanks for any help

    Regards

    Your assumption is correct.   The GET was simply not implemented during the implementation of the I2C driver. I see no reason why this cannot be implemented. There was no reset issues.

    If you are planning to adapt the existing library, which would be great, I strongly recommend we get you the very latest build to ensure your baseline is the latest release level.

    Send me personal message with your email so I can send you a link to the latest release.
