Shield Shield I2C #28

Closed technobly closed 9 years ago

technobly commented 10 years ago

I2C pins are not available where they are needed for Arduino Shields, and new Arduinos have an extended pin set also not supported by the current Shield Shield. There's probably a lot that can be done here for a more usable v2.0 Shield Shield.

Currently

Arduino   Spark Core  Shield Shield
A4 (SDA)  D0 (SDA)    D3
A5 (SCL)  D1 (SCL)    D5

* Arduino Leonardo also has dedicated SDA, SCL pins now

Also, we should consider changing the Logic converter that allows the use of I2C.

Another point is to map the I2C to the correct pins corresponding to the Arduino Uno.

dedicated mosfets for I2C FTW
