I bought a Barton LCD controller by a STE2004S used in I2C mode. (extended instruction set)
I just can't get the thing to display a thing.
Voltage is ok, fuses and such ok, I2C code works as I can talk to an eeprom and RTC.
The doc is really messy, sometimes they talk about 2 bytes command words, then three bytes...
Has someone ever managed to display something with that beast ?
Thanks.
Chris.
