We are using the ad5274 device to control an LCD contrast pin. I have successfully instantiated the ad5274 linux driver. The driver exposes a couple of files in /sys/bus/i2c/devices/000-02c. The files of note are rdac0, otp0en, and otp0. I can't find any documentation that talks explains how someone is to use these files to program the ad5274 device. Any help?
I would recommend starting a thread at the Linux and Microcontroller Device Drivers page on Engineer Zone for Linux driver related queries & documentation. They may not get an alert to check the query on the precision DAC section.
Will do. Thanks.
