So, I'm liking #𝚙𝚒𝚐𝚙𝚒𝚘 for some of its capabilities, but not so much other aspects. Like the bits of incorrect #documentation (𝘦.𝘨., a #dutycycle is a 𝗽𝗲𝗿𝗰𝗲𝗻𝘁𝗮𝗴𝗲, not a range), the lack of examples, and (most of all) the apparent inability to have multiple concurrent C/API processes accessing the #GPIO because #𝚐𝚙𝚒𝚘𝙸𝚗𝚒𝚝𝚒𝚊𝚕𝚒𝚜𝚎() starts the #𝚙𝚒𝚐𝚙𝚒𝚘𝚍 dæmon and fails if it's already running.

Where can a n00b #Pi GPIO hacker ask about these things?

I've spent quite a while searching online for a simple answer to this question, but no luck so far. I'm developing a #software #music #synthesiser, and I'd like to generate #pulseWaves of a given #dutyCycle, #frequency and #amplitude. What's the most #programmer friendly equation for this?

In case you're wondering, my synth is, of course, written in #Rust, using #PortAudio, and entirely for fun.
