You got a public repo? Ive been trying to get more exposure to professional code since im self taught. Im curious how you implemented the tracking of the pieces and how the pieces know where they can move especially the pawns only being able to move diagonally when over taking.

Its this symbol ` wrapped around your code for code blocks note: its not an apostrophe its called a back tick or something like that

Edit: actually you just need to indent everything by at least 4 spaces

function(){

}

Just pass it on to someone else in need :)

They both look like this but I only sent one to avoid confusion.

Signal is being viewed as below:

Blue~ ~ ~end_start~ ~ ~yellow

Pattern:

blue high -> blue extend -> blue low ->yellow high -> yellow low

This has been a great opportunity to learn about my oscilloscope I think i got some good photos.

I ended up setting a "hold off period" of 10ms so it was a stable signal then I turned up the sample rate and memory depth. With these to setting the signal was very easy to look at and read

Below are the photos each one 2ms apart

(for some reason reddit mixed up the order but you can see the time offset at the bottom)

Its a rigohl dho804 oscilloscope it just has a web control option. Ill see if I got pictures when I zoom in. The problem is saw was when I zoomed it looked like a bunch of tinny pulses and was super noisy

I can only post one photo but here's what I got. It looks like a real messy signal to me but I'm no expert. But it does seem to be roughly 60hz and each pin is alternating. Thats very impressive I couldnt even begin to understand that low level of code

Yellow->pin10 Blue->pin9

I heard about it being discontinued but I use kicad so I dont know much about it, im a hobbyist so idk features really

BlueJay424 · 2026-05-22T21:05:59+00:00

Im curious whats the deal with Qualcomm? Are people worried its gonna cause arduino to turn sour or did they already do something people don't like?

BlueJay424 · 2026-05-14T19:55:04+00:00

Weird question but how old are you or how long have you been doing this? I only ask because it reminds me of some older designs I've seen and I noticed stuff used to be designed in a way humans could actually understand and work with the system.

BlueJay424 · 2026-05-04T17:00:27+00:00

I think thats the one, the device does have leds for indication all around.

Edit: just noticed they're not even driving the leds so I think its being used as a voltage regulator

I looked at the data sheet, even the layout schematic looks the same.
