Even a blind hen sometimes finds a grain of corn. I'm not a programming expert, but I've a ton of hands-on experience in developing realtime closed loop controllers. > I'm on tablet forgive my laziness where are the ADC examples located in c > language if possible > See https://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/ChaExamples.html C examples including ADC: 1.c, io_input.c, rb_file.c Since I don't know how to generate graphical screen output in C (or Python), I didn't transform the further ADC examples (ie MM mode). They're FreeBASIC only. (Feel free to help out here.)
