Hi Stanley,

So I've got everything working.

This thread can be closed.

allright, After some patience and debugging, ive got something going on. I started with a clean sketch, added Wire.h to the project and issued a hello world on the I2C bus, then uploaded the sketch to the I2C adapter. -- On the other side, I used an Arduino UNO, started with a clean sketch as an I2C...

Also, are the unused IO pins pulled down or up or are they left floating? The kickstarter schematic does has the 644P, and from there it looks as if they are left floating. Any chance you can post the schematic for V2?

Any help is appreciated.

Thanks.

I can program it just fine, and have tried a multitude of sketches both using Codeblocks and Arduino builder and the ...

Hi, I've downloaded and compiled the sources for the adapters. However, I cant quiet tell the difference within the source between the two versions. I'm quiet sure that my I2C dongle is version 1. My questions are: What sort of config flags need to be declared to get the source code to work on the I...

Ive got the source loaded, compiled (untouched), and was having errors using the UNO as an ISP. After some tinkering, it seems that the sketch already loaded on the adapter stopped to func...
