I’m just starting out with the BBB. I have been reading a fair bit but haven’t found a coherent message on low level I/O access on Angstrom, and on Ubuntu. My goal: openCV, python, I/O control.
-
Angstrom is touted as having better low level I/O access than other OS’s-- in what way is this true? DTS files are not needed to start out with non-javascript access, correct? If that’s the case then what advantage does angstrom have.
-
If I’d like to access I/O without bonescript, is that of equal difficulty in Angstrom vs. Ubuntu? If needing to remap pins, the DTS files would exist in both OSs, so that’s probably the same level of trickiness.
But it’s unclear how hard or easy it is to access I/O with say C or Python on the two OSs
Does anyone have an example of the simplest low-level non-javascript I/O access?
