I2C display

Hi,
I came across a 1602 display IIC / I2C serie lcd 1602 modul display for (for arduino) bought on ebay, but no documentation except adr 0x27.
Anyone who has tried using something like that with picaxe? Is there a I2C standard for display commands and data?

These have been used with PICAXE many times and you can find code on the forum, but these modules are only an i2c port expander connected to a parallel LCD in 4-bit mode, so are more difficult to use than normal serial or parallel LCDs.

Have you tried searching?

The 0x27 Address is a 7-bit address. The actual 8-bit address is 0x4E and is the address you should use with Picaxe I2C.

Thanks a lot for very useful info! I will try the code posted by Rick100.
