I would like to sample N points of a waveform at a fixed frequency (more than 10KHz) using the internal ADC of VF61. Few days ago Sanchayan Maity added IIO buffer support for Hybrid ADC in linux kernel (linux-toradex.git - Linux kernel for Apalis and Colibri modules). I successfully build the kernel and flash it to Colibri VF61 board.
When I boot the board i can see the two adc (iio:device0 and iio:device1) in /sys/bus/iio/devices each one with several files and directories:
So I think that the driver is up and running properly. I would like to know what are the available triggers to start the sampling process.
