Hi;
I had been trying to write a slave LPCXpresso using A13 w/ WIFI. It always failed. I can't write on any i2c bus. It's always "Writing error" or "Communication error".
LPCXpresso is supposed to be set as Device (Slave) but no matter what I did, it didn't work.
I connected UEXT 5th and 6th pins (SCL & SDA) to use i2c and although I can use LPCXpresso from my PC, I cannot use through my A13 w/ WIFI.
I'm using Deabian prebuilt image from here: https://www.olimex.com/wiki/A13-OLinuXino#Linux
I don't think there could be a compatibility issue as I use correct pins.
Any help?
