Code speed and execution time

[tenaja]

I don't have your list of PICs memorized, so you'll have to read the datasheets. Just search for "master" in the i2c section and make sure it is not implemented in firmware.

GIven your 50/60hz output, I'm guessing a dc/ac converter? Most dc/ac converters use a "modified sine wave" that only has two or three steps in each direction. You should be fine with a lookup table...you can probably squeeze in a decent curve in the same space the s/w i2c commands consume, and save the hassle of the eeprom.

OK, Checked all my PIC's and find that the 18F14K50 is listed in the data sheet as having a Master Sync Serial Port.

I have tried the I2Cread and I2Cwrite with this and never got it to work. Could this be because it is hardware and not software?

I shall continue and report back at the next hurdle!!
