drumminhands Downloaded the files. I saved a copy of local.pd to _main.pd and loaded to an empty project.
Even once you fix the config-pin commands as above, this won't work: as you have some .cpp file in the project, it won't automatically load _main.pd
unless that .cpp file tells it to (and it doesn't in this case). See the last paragraph of the README:
You should test O2L (and any of the above mods and electronics) by running a Pd or Sc patch such as the enclosed ones on the host, while running this program on the board from the IDE. Once that setup is tested and works fine, in order to run a regular Bela program for audio/sensor processing alongside O2L, you will need to run the O2L program as a service on the board. See here for details on that.
Emphasize: "Once that setup is tested and works fine".
If you really want to test it without running anything on the board, in the setup() function in main.cpp, after
if(gLeds.setup("/dev/spidev2.1"))
return 1;
add:
for(size_t n = 0; n < gRgb.size(); n += 3)
gRgb[n] = 255; // all red. Use [n + 1] for green or [n + 2] for blue
gLeds.send(gRgb);
and all LEDs should turn red until you receive an OSC message.
