Запустил такой Recalbox на своём Raspberry Pi 3B+, решил запустить старую добрую Gran Turismo 2. Интро просто эпичное. Умели же раньше, а!

And I just made another #GitHub issue on #ToaruOS, this time requesting if I can merge my #RPi3 code changes.

I got #ToaruOS working on the #RPi3!!!

@blhue Had a recent experience where I ordered a #RaspberryPI3 from Amaxon and was sent an open box with a legacy #RaspberryPi2 inside. Guess someone got a FREE upgrade at #Amazon and my #TIME expense to return it back again.

Free Your Pi With This Bare Metal Programming Environment - [Rene Strange] has graced these fair pages a short while ago with a sweet Raspberr... - https://hackaday.com/2022/05/08/free-your-pi-with-this-bare-metal-programming-environment/ #raspberrypizero #raspberrypi2 #raspberrypi3 #raspberrypi4 #raspberrypi #programming #baremetal #c

Working on the WAvrVM firmware, today I finally got around to implement an op code parser for the serial protocol between the #raspberrypi3 and the #arduinonano via a HC-05 bluetooth module. The program already takes more than 50% of the available flash and SRAM.But I think everything will fit nicely.

After removing the adhesive side of the LED strips the other day, I put some solder on the pads. All in all I repeated this step for 270 pads.

I took the time to document the operations I implemented for my control software WAvrVM. That is a little VM that runs in an #arduino with an instruction set to calculate and set the pixel colors in an #neopixel #ws2812 RGB LED strip. Joined with the bluetooth module HC-05 a #raspberrypi3 or #raspberrypi3 can then upload new animations or just change the colors.

For the big LED panel project I finally found the time to cut the strip into 45 parts. Each 5 LEDs long. Also removed the adhesive pads of them, because it does not stick to 3D printed parts well. Going to use hot glue for this.

Soldered the LED panel circuit now. And it works like a charm! Next up on my list is working on the 30-40 LED panel version and finishing the "firmware".

I'm really out of practice soldering my own circuits on a perfboard. Don't know if a single circuit with a few traces justifies setting up a PCB etching station in my limited space here.

Designed an electrical circuit for the prototype perfboard I'm going to solder.KiCAD makes things easier if you know your way around in it. When I used it for the first time some years ago, it was kinda intimidating.But with version 5 KiCAD got more useable.

Next step in my LED panel project is soldering a more permanent board for the Arduino Nano and the Bluetooth module. Board layout is a hassle, I might look into KiCAD again tomorrow.

Currently I'm printing about 60 of my LED panels. With a black bottom to get rid of the light leakage of the bottom case and get a more defined shape of the lights once they are on the wall.

After my prototype was done,I printed more panels.I also added clips for cables on this revision,so I don't have to mess around with hot glue as much as before.Ask me if you want the blender/STL files, it might take some time before I prepare a post on thingiverse.

After some trial and error I finished the test of the software serial communication with the HC-05 bluetooth module. I also defined a fault tolerant serial protocol for writing new LED animations to the Arduino Nano.

#3dprint #3dprinting #rgbled #ws2812 #linux #diy #maker #programming #foss #floss #rustlang #rustprogramming #coding #raspberrypi2 #raspberrypi3 #raspberrypi #arduino #arduinouno #arduinonano #electronics

Eventually figured out the right baud rate.The problem was, that the HC-05 was documented with 38400bps for the AT commands, but the standard serial baudrate was 9600bps.And I did not know if the software serial was working correctly at all.Other issue was a wrong voltage splitter.

The Bluetooth serial module HC-05 seems to work fine. But I had trouble connecting it to the Arduino Nano (clone) via software serial. Good to have an oscilloscope to debug which pins the signal is actually being sent from and what baud rate is actually used (bad documentation).

I decided to go for a small Arduino Nano clone. I already bought many other original Arduinos over the years already. If you can deal with the downsides of the clones (bad driver support for instance, old bootloader), they are a cheap solution for eg. controlling a #ws2812 LED strip.

Don't want to spend more time than needed in C++ or the embedded world. So I decided to develop a little DSL with a byte code VM that is executed on the Arduino. It's fast enough to define interesting (animated) fades, and fill segmented parts of an LED strip.

Finally glued everything in place in my experimental small hexagonal LED panel setup. I still work on HexoSynth. But it's good and fun to take your mind onto something else for recreation. Once these lights decorate my living room/bed room, I can relax even better :-)
