Hi Pierrick! Have you tried libpruio <http://github.com/dtjf/libpruio> yet? It makes one PRU fetching samples from the internal ADC. Parameters are controled from the ARM side. Everything can get configured in user space (sampling rate, active channels, avaraging, and more). Device tree action is only necessary once in the install process. This make programming and testing much more easy.
For the ADC, my future application is going to be time critical, by this I > mean that I want to sample data at around 5khz to 10khz. Is the IIO driver > able to execute real-time data acquisition while the ARM is processing the > data? In such a case I'll start with ADC input by libpruio and a controller loop on the ARM. When real-time requirements cannot get fulfilled, the controller loop can get shifted to the second PRU later in the development process.
