Thanks for the suggestion. I'll keep that in mind if I need higher sampling
rates. However, I did find a way to read ADC through IIO so that it doesn't
hang.
First set up the channels and the buffer through sysfs:
echo 1 > /sys/bus/iio/devices/iio\:device0/scan_elements/in_voltage0_en
echo 256
Hi,
I enabled tscadc in the dts-file and then tried to read the ADC from
command line:
ubuntu@arm:/sys/bus/iio/devices/iio:device0$ cat in_voltage*
3961
3581
3933
2233
2272
3400
3187
3816
ubuntu@arm:/sys/bus/iio/devices/iio:device0$ cat in_voltage*
3960
3588
3936
2454
2500
2891
and here it hang

Hi,
I have a simple C program which writes something to a serial port and then
reads an answer, every 5 ms or so. I'm using an FTDI USB-to-RS232 adapter
connected to BBB at 115200 bps. In 3.8.13-bone63 this works fine, but there
are some reasons I need to use a later kernel. I upgraded to the
