Pi project ideas: There's a huge list right here on this sub! It took me awhile to realize I had using the vectorized for loop ( i += 4 instead of i++) so it was skipping every 4 samples causing a ton of high frequency noise.Friendly reminder: Please don't just post pictures of unused pis - do a project!Ĭomplete r/raspberry_pi Rules Check the FAQ and Helpdesk here Slightly more related: Once I saw a bunch of strange noise coming out of my DSP code, despite being pretty simple. This caused me to index out of bounds on the vector which for whatever reason drastically increased memory usage. Eventually I checked the device memory / cpu page really quickly before it hung and saw the memory spike hard after deserialization.įollowing my tracks back I noticed that my lua indexes to C++ indexes had an off-by-one error, since lua starts at 1 and C++ at 0. Whenever the unit deserialized it would work fine for a few seconds and then the entire device would freeze.Īt first I thought there must be a problem with my vector resizing instructions, but nothing I changed caused any difference. Recently my deserialization code caused the device to completely hang, but worked fine in the emulator.

My approach has usually been to slow things down so it’s visible on the scope or record the output and zoom in on the waveform in the editor.īesides that, sometimes I’ll output simpler parts of the problem that I expect to be working and make sure they look good before mixing them back into the solution.įor timing mismatches though, idk if there’s much more you can do than just think really hard about it.Įdit: A small possibly unrelated anecdote. (meanwhile, i’ll be installing that prerequisite of Xcode command line tools…) (e.g.: is ‘brew’ the package manager on macos? just like ‘apt’ is on debian based linux distributions?) but it would also add more information for those who are not at all familiar with the concepts on macos. Of course, it would have the instructions that are already available in the readm.md. but i was wondering if it would be anything worth to begin a new thread that would have step by step instructions for a macos rookie. I’m sure i could bug you with my questions here in this thread. Little apple thingie sitting here (mainly for musical reasons) and i’d love to learn the apple way of things… I would feel rather confident to do all this on a linux machine. You have to have the Xcode command line tools installed beforehand, and after the “brew install…” command, you have to type “git clone ” which clones on your drive the actual emulator : do you think this information should be added to the again, as well as all the other macos people here:
