What Device on the I2C bus of the Cyclone V SX SoC development board uses address 0x17?

Hi,

I'm having some problems with the I2C bus-0 on the Cyclone V SX SC SoC development board.

I use this I2C bus for my capacitive touchscreen (address 0x40), what is working but after a some time the entire I2C bus-0 is stuck, because of one device keeping the SDA grounded. Which resolves in to this error:Only way to get rid of this error is by cold rebooting the development board.

On the I2C bus are 10 devices. 9 of these are known to me but the device with address 0x17 is unknown to me.

I did like to know what device is using address 0x17, because I think this is the device that is causing my problems.

Thanks,

Peter
