Tool/software: Linux

Hi Team,

Do you have Linux driver for this module?

If it's not, Could you please suggest the best approach like

1) Write kernel space ADC driver as already written some driver in "drivers/iio/adc/" directory in Linux kernel

2) Use spidev to write user space driver.

if any other method, please suggest.

Thanks,

Hardik

Hardik,

If this is for the ADC54J20EVM, you can use the FTDI's D2xx driver on Linux to program the ADC board.

The FTDI device on the ADC EVM can be configured in bit bang mode to do the SPI configuration. We haven't prototyped this so far but we know FTDI driver API works on a Linux machine.

Regards,

Jim

Hi Jim,

Initially we tested EVM and now we are using SPI/JESD lines connected with processor.

I want to access adc device using "/sys/bus/iio/devices/iio:deviceX" files in Linux.
And for that we need Linux iio driver similar to https://elixir.bootlin.com/linux/latest/source/drivers/iio/adc

Is there any driver available or any driver close match to this adc ?

Thanks,
Hardik
