    • Issue Reading GPIO 1146 (Pin 6 on J10) on VOXL2

      Hi,

      I'm trying to read values from GPIO 1146 (Pin 6 on J10), but the value always remains the same regardless of whether I connect it to 3.3V (high) or 0V (low).

      I successfully changed the direction to output and verified using a multimeter that writing '0' or '1' correctly changes the voltage.

      However, when I switch the GPIO to input mode, reading /sys/class/gpio/gpio1146/value always returns the same value, regardless of the external voltage applied.

      It seems that the value read from /sys/class/gpio/gpio1146/value is actually determined by the contents of active_low, rather than the actual pin state.

      voxl2:/sys/class/gpio/gpio1146$ cat /sys/class/gpio/gpio1146/direction
      in
      voxl2:/sys/class/gpio/gpio1146$ cat /sys/class/gpio/gpio1146/value
      0

      Is there a known issue with reading input values on this GPIO? Do I need to configure anything else (e.g., pull-up/down settings) to get correct readings?

      Thanks!

    • Voxl-mapper realtime cpu usage

      Hello,
      On this video: https://www.youtube.com/watch?v=gqlSKRP8prc
      you've showed the voxl-mapper service on a drone equipped with VOXL.
      I assume the mapper is running at real time and do not need to be run as a post process?
      I was wondering if you can elaborate at the CPU usage this service takes in order to create a map as in the video.
      If you can share this data, both on the VOXL and VOXL2, that would be great!

      Thanks!
