Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi Grog,

where can i find the I2C pins on your board?

The Microchip manual shows pin 36 for SDA1
and pin 37 for SCL1, but i can't find this pin numbers on the silkscreen.

I2C - pins 43(SDA) and 44(SCL).

Manual, page 11 for pinout of the E64.

EDIT: First Jim, now YOU beat me too it!

Well done. Yeah, I think the pin assignments changed around a bit in the early alpha versions - not sure if you were involved in that or not. The PDF manual in the download from Geoff's site lists the correct current pinouts.Edited by Grogster 2015-08-19

Smoke makes things work. When the smoke gets out, it stops!
