Hi Zubair, I have here am335x-evm board. The output of voltage4 (via `cat /sys/bus/iio/devices/iio\:device0/in_voltage4_raw´) returns values in the range 570…580. I tested the continuous sampling mdoe by executing the following commands:
|echo 1 > /sys/bus/iio/devices/iio\:device0/scan_elements/in_voltage4_en |echo 25 > /sys/bus/iio/devices/iio\:device0/buffer/length |echo 1 > /sys/bus/iio/devices/iio\:device0/buffer/enable |sleep 1 |echo 0 > /sys/bus/iio/devices/iio\:device0/buffer/enable |cat /dev/iio\:device0 > iio |hexdump -C iio and the output is: |00000000 37 02 92 02 1f 07 0a 06 20 06 31 06 2f 07 2a 07 |00000010 2b 07 2d 07 2c 07 28 07 2c 07 2b 07 2b 07 0c 06 |00000020 21 06 32 06 2e 07 2c 07 2a 07 2a 07 2c 07 2b 07 |00000030 29 07 27 07 28 07 29 07 2a 07 0d 06 21 06 35 06 The first entry is in the range that I would expect. The second is slitghly higher. The third and following entries are out of range. Have you observed something like that? Is my testing close to what you have done or did I make an mistake here?
