If one-shot mode is enabled, then the sequencer will only be scheduled one time the sequencer HW will automatically disable the StepEnable bit after it is scheduled which will guarantee only one sample is taken per channel. Zubair Lutfullah 17 August at The subsystem maintainer Jonathan Cameron was asking about your email address.. Zubair Lutfullah 21 June at Hi Zubair, I need to read all 7 analog inputs of the BBB every 5 milliseconds for a real-time audio app.

EBC Exercise 10a Analog In
I’m using the prebuilt systemd image, so I may be missing a required package. Did you notice that before?
ADC, Sitara, Touch screen. Retrieved from ” http: And trigger is not implemented by the driver anymore. This is not the same with the iio-trig-sysfs module. Zubair Lutfullah 1 January at The linux kernel folk didn’t like linuux trigger handling this way as it wasn’t how iio usually handled triggers.
One cannot read ADC data from one channel operating in One-shot mode and and other in continuous mode at the same time. Any idea what it could be?

There is an Audio cape available. This page was last modified on 8 Julyat The name should be in sysfs somewhere. The ADC samples the analog signal when “start of conversion” signal is high and continues sampling 1 clock cycle after the falling edge.

Why do you wish to use the ADC for sound capturing? To sum up, you need to run the following to read continuously from linxu ADC. If you wish to enable another channel. Newer Post Older Post Home.
When the ADC sequencer finishes cycling through all the enabled channels, the user can decide if the sequencer should stop one-shot modeor loop back and schedule again continuous mode. You don’t have a supported kernel. Sorry for the confusion.

You need the latest kernel uImage file for these.

Craig Markwardt 8 October at It is important particularly in interfacing with sensors where most throw varying voltage levels that represent varying physical quantities temperature, pressure, etc. Zubair Lutfullah 30 September at You might have noticed that you haven’t exactly specified which channel you wish to sample.
And Y is your analogue channel number. I followed all the instructions and when I run. But I’ll be updating the blog soon with the new stuff.
