really the problem is getting it to respond to any kind of input while doing that. ESSPECIALY because analogread() takes so many cycles.

A picture could be worth a thousand words, but in my case it's 2000 characters.

Also, my code is more. I had to split the code. That's sad...

Also, also, cutting and pasting code sucks on mobile...

Arduino IDEでもCH32シリーズが使えるって聞いて一時期使ってみてたけど、analogReadがうまいこと動かなくて投げ捨てた記憶がある。

analogreadとかあの辺の基本的な共通API、何も考えなくても高速に動いて欲しい…プラットフォームごとにレジスタだったり専用api叩かなきゃやってられん

Feed: "Slope of Hope with Tim Knight"

Analog Waterlogged
FEEDYou’d think since I’ve been mixed up in tech since 1980 that I would know my way around the terminology, but until now I never really grasped what an “analog semiconductor” was. It sounds like an oxymoron. All this time, I figured TXN wasn’t much different than NVDA or any other semiconductor company. Wrong! AnalogRead More 0 Comments

i never did get it hooked up to an actual board, but playing around with functions is fun

function analogRead() {
// random noise
return lerp(0.14, 0.86, Math.random());

メモリーキーヤーにCH32V003使ったけどArduino IDEで使うならanalogReadが動かないって話見かけたし実際うまいこと動かなかったから諦めた。

MounRiver Studio使うなら動くんだろうけどなんも考えずに書けるArduino IDE使いたいし。

On, and I want to explore the random seed generation which is calling analogRead() on pins with short wires attached to them. I suspect it's not really THAT random. I want to explore better sources of randomness, or discover that this wire method actually works really well.
