On another topic has anyone used the 12C? LCD in the sketch as it only needs 4 wires with a built in pot as well. I used the 12C LCD in a sketch on my mill feed but the sketch was preconfigured? by someone else. I had a dabble with trying experimentally to introduced the LCD 12c in an earlier RELS sketch but it came up with errors
Leslie,
Re your question, the I2C pins on the ATMega 2560 are pins 20 and 21. These are already used in the RELS to read the pulses from the encoder and are not available for communication with an I2C display. If the pins were available, the sketch would need to be changed to accommodate the different communications method.
