Firsts steps in the Arduino sonar! A friend of mine sent me some days ago the link of one of those prebuilt, but it's funnier to do it by myself!!
Getting used to the SC-SRO4 ultrasonic sensor by measuring the distance of an object and classifying it in 3 categories.
Next step: show the distance on an LCD screen.

Mein neues Lieblingsthema #meshtastic 😁

Was ich mich frage:
Die Nodes laufen ja alle auf bekannten Mikrocontrollern, z. B. dem #esp32 und wir können sie programmieren, z. B. über die #arduino IDE oder #platformio
Können wir dann auch eigene Programme schreiben, die auf die Meshtastic-Funktionen (senden, empfangen usw.) zugreifen?
Gibt es dafür #libraries ?

Würde da gerne etwas im Zusammenhang mit #geocaching programmieren.

Weiß jemand was? Habe bisher im Internet nichts zu dem Thema finden können, außer der Library „Meshtastic-arduino“
https://github.com/meshtastic/Meshtastic-arduino

Die dient aber nur dazu, Meshtastic-Nodes über #serial oder #bluetooth zu steuern, also nicht direkt das, was ich suche.

Кубик мысли: простой проект, который говорит вместо тебя

Предупреждение для читателя: Эта статья — не гайд, не туториал, и уж точно не техноблог. Я не инженер, не блогер и не эксперт по микроконтроллерам. Просто человек, который в один вечер решил разобраться с ESP32 и внезапно собрал «Кубик мысли». В этой статье я расскажу, как появился мой Кубик. Что он делает, из чего собран, как работает и зачем вообще нужен. Если вы ищете сложную электронику или гайды уровня “с нуля в продакшн” — тут не об этом. Зато, может быть, вы вдохновитесь и сделаете что-то своё. А это уже будет значить, что статья не зря.

Is the Teensy 4 still the speed queen of hobby micro controller boards? It's 7 years old (approx); shouldn't something faster have come out?

Yes, the title of this article sounds pretty crazy. But not only is it entirely possible through the lens of physics, but it is also practical to achieve in the real world using affordable parts. Jon Bumstead pulled it off with an Arduino, a photoresistor, and an inexpensive portable projector. Today’s digital camera sensors are […]

Ok, starting to get a little silly now, but I thought I'd try to use the AY-3-8910 as a 4-bit DAC for Mozzi synthesis...

Hey #FediHire , meet @Dominicd3213

He's an embedded systems and #fullstack #developer who loves making machines move and websites work. By day, he wires up #Robots with ROS 2, #arduino and LIDAR; by night, he wrangles #react #TypeScript and #MongoDB into sleek, responsive interfaces. Built #AI chat tools, and co-founded a trading platform.

He lives where code meets circuits, and believes great tech should be powerful and weird.

Anyone need a bright young guy like this?

Let's make sure we absolutely have the right pin.

A good sanity check is that VSS connects to at thick ground copper, and M/IO connects to a via, that we can trace out going to the correct header pin.

*sweating*

OK, without any clock source this thing should barely draw any power.

Half a watt seems about right. Much more reassuring than the 286 was!

Show threadgloriouscowJun 21

This is a 3V capable CPU though, so we'll run the board at 3V. It draws 0.1 W at 3.3V which is even better.

Still wondering what happened to my 80C286. Wish I had a system I could throw it in to see if it was actually dead or if I'm just a bonehead.

Show threadgloriouscowJun 21

here's what i have to patch over to the Arduino

50% chance i have one or both of the address headers backwards lol

Show threadgloriouscowJun 21
This should be it! It's the same gpio pinout as the 286 basically. The 386EX actually only has two more address lines. I guess 64MB of RAM is plenty for embedded applications...
Show threadgloriouscowJun 21
Lucky that this header just happens to have CLK on it.
Show threadgloriouscowJun 21
Conspicuously absent on the 386 is an ALE pin. I guess timings are now tight enough that you only concern yourself with the address when a read or write signal is asserted.
Show threadgloriouscowJun 21
No bus status, no ALE pin... I guess I know the CPU has reset if it just reads something.
Show threadgloriouscowJun 22

And I thought the 286 took a long time to reset.

450 cycles!

Show threadgloriouscowJun 22

So far no response from the 386EX.

Time to do a sanity check to determine whether the RESET and CLK signals are really reaching the CPU.

Show threadgloriouscowJun 22
The header provides a tie to /RST, that is an inverted RESET signal. This is one of the signals that passes through the inverter IC, a 74HC14D. I should check that the inverter is still receiving power after my board surgery, and that a positive RESET signal is coming out the other end of it.
Show threadgloriouscowJun 22
Well, this is unfortunate. The holes in the board i assumed were for mounting posts actually seem to be connected to each plane and by putting screws in I have shorted the board.
Show threadgloriouscowJun 22

The EX datasheet doesn't mention the particulars, but the SX datasheet has this to say:

I'm not sure how this board ties the busy pin. If it isn't low we're gonna be waiting a million cycles for it to reset.

Show threadgloriouscowJun 22
BUSY is multiplexed with TMRGATE2 on Pin 92. It looks like this runs through a resistor network with a pulldown to ground (figures) but does go to a header pin curiously claled TMRCLK2. Typo perhaps? I hope so.

@gloriouscow Maybe they replaced it with a BEER pin?

@ozzelot I remember one of the early xbox mod chips had a tiny ass little wire like this you had to solder. and of course once I installed mine all my friends wanted me to do theirs.
