quick help - linux Industrial IO Hardware Triggers
Hi List, Thanks in advance. In the existing IIO drivers (linux-3.16), my understanding is that Hardware Triggers are just used to copy sampled data from the ADC to the Kernel buffer. I think none of the hardware triggers are really configuring ADC to Start the analog to digital conversion. I have a Hardware Counter on my Board. I am planning to configure my Counter overflow interrupt as an IIO Hardware Trigger. In my IIO ADC driver probe function I am planning to start my Counter for the first time. Once the counter overflow interrupted is generated, inside the counter ISR, I am planning to configure ADC to start analog to digital conversion on all the channels (4 of them), one sample on each channel and once the Conversion is completed, I am planning to copy the Sampled data to Kernel buffer associated with the Trigger. I will program the Counter again and wait for interrupt and repeat the steps above. I am planning to continue this approach indefinitely. Does this approach satisfy the principles of IIO Subsystem ? Am I missing anything here in understanding the IIO Subsystem properly ? Thanks in advance, Sricharan, Pune (India). ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
