I picked up an LCD mounted on an I2C enabled backboard. I'd like to interface it with my Gumstix + Robostix combo. I've hooked up ATM_SCL and ATM_SDA as well as power and ground to it. I have a couple of questions:
1) How do I find out the address of this device? When I modprobed i2c-pxa, I was expecingt to see a list of all devices. Instead, I get nothing (I2C is working, as i2c-io works fine).
2) When I hook up the LCD, I can't seem to talk to my robostix anymore. Do devices change address? Why is the robostix referred to as device 0x0b in the first place? How is this all configured?
