Controlling ADC SPI devices

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

my name's Anthony & I need some help with the following:

Reading ADC values from mcp3208 on the spi bus within my custom made kernel module.

I'm able to read spi values thru /sys/bus/iio/devices/iio:device0 no problems but I need access it from within my drivers.

I've tried using dev_to_iio_dev(dev) but can't seem to claim the *dev allocated for the spi device.

How can I get a ref * to the device?

How can I tackle this using iio method?

Thanks i advanced!


Anthony
