ScreenBuffer when compiling patches

OWL Magus
#1

I’m trying to write a patch which makes use of the screen on the Magus, but it looks like whatever is compiling doesn’t have the proper configuration of #define’s for ScreenBuffer:

Also, is there a way to build and deploy patches locally without going through the web portal?

#2

I’m not sure what’s current state of web UI (always build patches locally), but I’m pretty sure that device-specific features were not supported there. And not every Rebeltech device has a screen, obviously.

This is the repo for building patches: GitHub - pingdynasty/OwlProgram: Dynamically loaded OWL program . Setting it up for Linux is not too hard, I think Readme goes into sufficient details. You’ll need to have working GCC Arm toolchain and build FirmwareSender program for uploading them.

#3

The problem has been that we can’t compile both with and without screen support unless we use pre-processor defines, which have to be indicated to the build process. And the online compiler doesn’t support that. So atm you need to compile offline, as @antisvin says.
However I think it would be possible to change the way that screen support works so that the required code is only compiled in when needed. I will have a go at getting this to work.
