Hello all. First, i introduce myself. Olivier, having basic programming language.
I bought a Beaglebone Black. My goal is: * Use OpenBSD and nothing else, no matter how is difficult, i will use what is available * Learn how to program the BBB. (I am aware that C libraries for this platform are not really distributed) * Make home automation (I also play with arduino uno) Status: For the moment, I manage to light via GPIOCTL, a LED on the pin 23 header P9. $ doas gpioctl gpio1 17 on my /etc/rc.securelevel: # Digital Output: gpioctl gpio1 17 set out pinH9_23 gpioctl gpio3 21 set out pinH9_25 gpioctl gpio3 25 set out pinH9_27 Question : in this way (I am not an expert in programming): _ Should I create a tree (directory) to turn on my LED in C language ? _ Should I instead use the physical addresses to turn on my LED in C language ? _ Regarding analog inputs, are they recognized by the kernel as GPIO ? _ Do you have some interesting link to documentations, to help me ? Thanks in advance. Olivier.
