[stamp9G20] I2C pins assignment

Submitted by ffiquet on Wed, 08/18/2010 - 09:23

Hello,

I'd like to change i2c pin assignment on my board (because I need to use ETX2 and ETX3 for MII interfacing).
I guess I only need to modify '.sda_pin' and '.slc_pin' in 'at91sam9260_devices.c' file.
- Someone can confirm ?
- Are they any precautions or considerations I have to take to care before doing it ?

Many thanks

Frederic

Yes, this is correct. Changing the assignment of these two pins is all you need to do. The only precautions you have to take care of are that you do not use the new pins otherwise.
