(...) The PICkit comes with a little PC board with a 16F690 on it. I don't know how that compares to the 16F88, but it does have a synchronous serial port. (18 years ago, 31-May-07, to lugnet.robotics)

(...) We actually worked a lot with the 16F88, which is a really great chip, something like a combination of the 16F628 and 16F819. But we didn't play with the I2C module on it yet. So that must obviously be our next challenge. (18 years ago, 31-May-07, to lugnet.robotics)

Hi, SetBrickDataName(str) seems to be able to only change the name of the nxt temporarily. Once the nxt is started, it loses the name assigned thru the SetBrickDataName earlier. Idea? --Elizabeth (18 years ago, 31-May-07, to lugnet.robotics.nxt)

Great timing. I just bought a PICkit2 to play with the other day. Any chance you already have the I2C slave interface for the NXT for the PIC? That way I can only concentrate on the specific code for a custom input/output device. (18 years ago, 30-May-07, to lugnet.robotics)

Hand crank it alone should be find. As a matter of fact, that's how we demonstrate to kids a generator.
