i2c scan error
Posted: Tue Dec 21, 2010 2:42 am
Hello,
I connected a sub-20 board to a Maxim MAX9526 Eva kit which has 3 i2c slave devices. However, I can only scan 1 of the devices. When using another USB-I2C board, I can successfully scan all 3 devices.
Is there a limitation on the number of devices supported for I2C mode?
By the way, I tried doing the scan using my linux workstation and my windows laptop and obtained the same result. It always return 1 device address.
Thanks.
