Well, indeed zynthian dependency of WiringPi is not so big. Most complex code is user-space i2c stuff for managing MCP23017. We could move to kernel’s i2c-dev library quite easily. For the native GPIO stuff, moving to libgpiod seems to be the way.
Yes. I also found some of this LV2 plugins and i suspect the number will go up, so yes, we need to support this “LV2-parameters”. Do you know, @riban, if the “grouping” mechanism is also implemented for “LV2-parameters”? I couldn’t found any info about it. Well, indeed, the documentation about “parameters” is also scarce and too-cryptic. As someone told me, LV2 docs are clear after you understand the subject of the documentation
