#69942 Not sure if this is the right part of the forum ..but if not moderator please move Using the Node MCU and EPS BASIC to drive an LCD display down the I2C bus and it does not work...

The problem is if you look at the hardware it has an PCF 8574A which sits at address decimal 61..the BASIC LCD Print command will not send data to this address, nor does it let you declare a different address.

OK for displays driven by the PCF 8574..but remember to include " " in the print statement, that are not shown in the online manual.

Not trying to criticise just pass along the fruit of a lot of hours work.....Yes I have a fix too
