Search - "esp32"
Well, I was Always into Computers and Games and stuff and at some point, I started wondering: "why does Computer Go brrr when I Hit this Button?".
It was WinAPI C++ and I was amazed by the tons of work the programmers must have put into all this.
13 year old me was Like: "I can make a Game, cant be too hard."
It was hard.
Turns out I grabbed a Unity Version and tried Things, followed a tutorial and Made a funny jet Fighter Game (which I sadly lost).
Then an article got me into checking out Linux based systems and pentesting.
*Promptly Burns persistent Kali Live to USB Stick"
"Wow zhis koohl".
Had Lots of fun with Metasploit.
More years pass, we annoy our teacher so long until he opens up an arduino course at school.
We built weather stations with an ESP32 and C++ via Arduino Software, literally build 3 quadrocopter drones with remote Control and RGB lighting.
Then, Cherry on the top of everything, we win the drone flying Contest everyone gets some nice stuff.
A couple weeks later my class teacher requests me and two of my friends to come along on one of their annual teacher meetings where there are a bunch of teachers from other schools and where they discuss new technology and stuff.
We are allowed to present 3D printing, some of our past programming and some of the tech we've built.
Teachers were amazed, I had huge amounts of fun answering their questions and explaining stuff to them.
Finally done with Realschulabschluss (Middle-grade-graduation) and High school Starts.
It's great, we finally have actual CS lessons, we lesen Java now.
It's fuckton of fun and I ace all of it.
Probably the best grades I ever had in any class.
Then, in my free time, I started writing some simple programs, firstvI extended our crappy Greenfoot Marsrover Project and gave it procedural Landscape Generation (sort of), added a Power system, reactors, Iron and uranium or, refineries, all kinds of cool stuff.
After teaching myself more Java, I start making some actual projects such as "Ranchu's bag of useful and not so useful stuff", namely my OnyxLib library on my GitHub.
More time passes, more Projects are finished, I get addicted to coding, literally.
My days were literally Eat, Code, sleep, repeat.
After breaking that unhealthy cycle I fixed it with Long Breaks and Others activities in between.
In conclusion I Always wanted to know what goes on beneath the beautiful front end of the computer, found out, and it was the most amazing thing ever.
I always had constant fun while coding (except for when you don't have fun) and really enjoyed it at most times.
I Just really love it.
About a year back now I noticed that I was really quite good at what I was doing and I wanted to continue learning and using my programming.
That's when I knew that shit was made for me.
...fuck that's a long read.5
How can I be so fucking stupid?
I was developing and testing a small webserver running on an ESP32.
3 fucking hours were wasted resolving connectivity problems because I did not realize the fucking VPN on my PC was still up thus hiding my ESP32's IP.
How fucking brainless...
I've cie ked everything. Dead flash, wrong offsets, compiler warnings, CPU freq. config...6
My ESP32 arrived today! I'm probably gonna be using it to make a programmable guitar pedal, but does anyone else have any ideas?10
i'm writing a custom web server for a project (esp32 based)
each 4 connections system crashes (cannot bind socket anymore)
i was so angry with espressif thinking that was their fault (bad implementation of posix sockets)
but is mine...
today i did another code review and I just discovered that i missed a fucking close() in the websockets handler
i wasted a month on this issue.1
Hey hardware hackers, just wanted to let you know that seeedstudio offers free PCB assembly. I got 5 pieces of the PCB in the picture for 30 USD manufactured, assembled and shipped (including BOM costs), the also included 5 additional empty PCBs. However I paid another 30$ for customs and DHL customs handling (I'm inside Europe) ... But still, for assembly it's a great price, took around 4 weeks. Just upload the BOM and you get an instant quote. If you are curious, it's a simple board for an ESP32 with some mosfet drivers and two DC-DC converters.
I’ve been trying to implement an alarm clock as an example for my physical computing lecture but the merge of my existing low power clock with my existing state machine based timer is driving me nuts. And I’m the lecturer of this course!2
*me discovering esp32*
Wow it's amazing!
i'll get one for my project.
*me working with esp32*
I ported my project to esp32, and.....
Wtf!?! after some time (unpredictable 1sec to N mins) i2c devices stops working. (i2c reset doesn't solve)
I lost several weeks trying to fix that
I felt so angry.
then I realized that it's not my fault
it is a bad implementation of i2c api by espressif.
at this point there is only one thing to do.
throw away the esp32!
(at least for some months waiting for espressif fix)
now i did a git revert and switched back to arduino.
now everything works and it's an awesome sensation!5
I just got an some ESP32 so I started playing with idf by espressif that it's released under apache 2.0.
So i thought "it's open source"
I spent 10 minutes searching for low level WiFi and BLE APIs on github.
Then I found an old issue
where an espressif dev says:
"The low level Bluetooth & WiFi implementations are proprietary"
they distribute Binary files in another repo also under apache 2.0.
-- (obviuosly) except reverse engineering.1
I lost the last few days trying to understand what's wrong with my esp32 project (i2c is unstable),
I felt so angry.
then i realized that it's not my fault.
but it's a bad implementation of i2c api by espressif.
Now i have to wait for their fix😴
Fucking finally something i can do while this corona crap is going on. ESP32's arrived today and i had to port entire project to them.
Luckily libraries support it so no problems there but the Bluetooth stuff is different kinda.
And oh fuck is it fucking faster. Oh yes. And as added bonus it fixed my main bug somehow.
The bug was that random stuff would show up in the Bluetooth log. Like random char's.
Anyways. That's fixed so now just add nice LED control to it so i know when I'm sending and receiving and then encryption.
Yes Yes i know project without using encryption and i send data trough it. Well if you want to help you can.
Sadly this ESP32 crap fucking broke Arduino support.
So yeah. Lets have fun while I'm sitting home.10
Does anybody here have experience with building a drone? Specifically with automatic controls?
I am working on one in a team of 2 (I'm on the software side, he's on the hardware side) for a school project.
I have an esp32 and a LSM9DS1 gyro/accelerometer, but I'm struggling with how I could implement an auto steering function.7
After messing around with an esp32 for hours I figured out it was the piece of shit router that was blocking all my traffic.
My data bill is not going to be pretty this month
Wtf is this ESP32 shit and it's hype?
I bought one because I thought JS on a microcontroller? That's gotta be fun!
I'm a hobbiest when it comes to MCUs and I do JS as a job, so I tought I'm made for this and I know at least as much as all the kids on the internet doing it.
Nothing makes sense with this shit. You have to flash wildly compiled modules of WHATEVERTHEFUCK with fucken python development-kits which have something to do with Lua to give you some kind of node-REPL which answers you with a bunch of strangely-looking errors starting with "stdin:x:".
If this NODE-MCU shit is made for JS why is there stuff about Lua everywhere you go with this, I don't get a single thing. Now I'm sitting on about 3 different git repos of sdks or what do I know and know less than before.
Oh and there is actually not a single tutorial really targetting the esp32. it's all about that 82xx-model.
Then I start googling around a bit more - It's not even ES6, it's just some ES3/5 shit. Why would you even do this. That's actually harder to manage than classic C/C++. You get no gain with it. Fuck me.
