The older serial LCD 2x16 is not available and I need to change to this newer version. The website does not show any I2C documents. Does anyone know where the commands are posted?

Edit I see some notes about this LCD being used on the "I2C Device Bus Scanner Utility" Maybe some code examples are in that code I'll check it out.

Thanks

I'm assuming you're after P1 code... not sure why I did that

Search for "PCF8574" here : https://obex.parallax.com/obex/
P1, P2 and C drivers come up.

Thanks! I use a PCF8474 on my board, interesting it is used for the LCD also.
