burning firmware onto an ST-Link to burn firmware onto anything else
7 days ago • 0 comments

at least I'm trying to find that out. The clones from aliexpress are supposed to be only able to program st chips. But I want to use it to program some SAMD-21 chips. Never done that as well. So this is a link drop first. Figuring it out for MAC OS.

install open-OCD via homebrew

for unlocking the stm for new firmware go here

https://hackaday.io/project/162597-st-link-clone-repurposing/log/156668-programming

install new firmware called cmsis-dap

https://mvdlande.wordpress.com/2015/10/05/cmsis-dap-on-a-cheap-st-link-v2-mini-adapter/

get this file

https://raw.githubusercontent.com/x893/CMSIS-DAP/master/Firmware/STM32/hex/CMSIS-DAP-STLINK21.hex

install with this line
```
openocd -f interface/stlink.cfg -f target/stm32f1x.cfg -c "init" -c "halt" \

    -c "flash write_image ./CMSIS-DAP-STLINK21.hex" -c "shutdown"
```
doing this to flash arturos latest keyboard firmware, had to install arm gcc first. Brew doesn't work as it's not trusted. Downloading here helped.

2019 Bigger Projects
- #Club Matrix
  Array of 10 8x8 WS2812B LED matrices, controlled by a Raspberry PI through a DMA library. Images can be send as UDP packages to the matrix, if you happen to know the IP address.
- SX-64 inspired Raspberry PI case
  Inspired by portable computers from the 80ies, I started to build a case around a Raspberry PI with 10mm extrusion profiles and lasercut panels to mount stuff to. https://www.youtube.com/watch?v=vXGr7-_U_tY
- #400 LED XY oscilloscope
  For another video done for "elemen14presents", I cobbled together schematics out of Forrest Mims III's engineers notebook to make an LED oscilloscope that has 20 x 20 10mm LEDs.
- #LED handheld
  This monster pixel game uses some tricks like charlieplexing, soldering LEDs upside-down to shine through the PCBs and hours of sanding on a 3D printed case.
- plenty other projects for element14presents
  Here's a list of all my appearances as a video host for element14presents, plus some extra episodes of livestreams of the makercast - podcast that me and some other youtubers started.

SX-64 inspired Raspberry PI 4 thing
11/26/2019 at 15:50 • 0 comments

So I've made this thing for element14 presents, never really had a set and forget PI to work on. I do like the optics of the SX-64 very much and all the other "portables" from the 80ies. I went with makerbeams 10x10mm aluminium extrusions for the frame and some lasercut MDF to hold everything together. Still needs an enclosure, but I'm pretty happy with it.

I tried to make the 2K display work, but it was too flickery and I couldn't get it to work properly, so I switched to the official display.

Things I've Built

Tampermonkey scripts for hackaday.io

Some annoying things like the feedback button and design stuff. https://gist.github.com/davedarko/f6ef86c89c4d1df4cd36

Batman LED caps

Put a cap on a strawhat LED and you will get a small batman projector.

IKEA Expedit LED plug

Throw in some WS2812 LEDs and snap it on the crossings.

PiMac

3D printed case for the raspberry pi in a not so common but very known shape. Inspired by http://hackaday.com/2014/01/16/hackintosh-mac-pro-replica-using-a-trash-can/

Fubarino Contest: Game Boy Printer

A little library for the gameboy printer for an easy intergation into arduino sketches. Cross the serial streams (watchout Egon) on startup, it will print the had url. http://hackaday.com/2013/12/17/fubarino-contest-game-boy-printer/
