https://www.lexaloffle.com/bbs/?uid=60375 <p>For some time now I have been thinking about making a large 128x128 LED Display for the PICO-8 and finally I did it.</p> <img style="margin-bottom:16px" border=0 src="/media/60375/led_screen.png" alt="" /> <p>What i used for this project:</p> <ul> <li>P2.5 RGB pixel panel HD display 128x128 (<a href="https://www.aliexpress.com/item/4000057689390.html">https://www.aliexpress.com/item/4000057689390.html</a>)</li> <li>Raspberry PI 4</li> <li>Analogue of Adafruit RGB Matrix HAT for connecting Raspberry with LED Matrix (<a href="https://www.amazon.com/Adafruit-RGB-Matrix-HAT-Raspberry/dp/B00SK69C6E/">https://www.amazon.com/Adafruit-RGB-Matrix-HAT-Raspberry/dp/B00SK69C6E/</a>)</li> <li>2.1mm Plug to Screw Terminal Block to connect the pixel panel power supply to the RGB Matrix HAT (<a href="https://www.amazon.com/Adafruit-Male-DC-Power-Adapter/dp/B00KAE41RE">https://www.amazon.com/Adafruit-Male-DC-Power-Adapter/dp/B00KAE41RE</a>)</li> <li>Additional longer hub75e 16pin cable to daisy-chain martrices inside pixel panel diagonally</li> </ul> <p>Selected pixel panel is well assembled, it is easy to arrange all Raspberry PI guts inside case, but:</p> <ul> <li>It has a pre-installed LED matrix controller, but it is not required for this project, so this is an extra cost</li> <li>16 pin cables too short to daisy chain 2 matrices for use with RGB Matrix HAT</li> <li>For now I don`t understand if its possible to draw enough power from pixel panel unit to drive Raspberry PI so I have to use a separate type-c power adapter for it</li> </ul> <p>For displaying PICO-8 on LED screen i wrote simple C++ program and couple bash scripts, you can find them on github: <a href="https://github.com/jenissimo/pico8-led">https://github.com/jenissimo/pico8-led</a></p> <p>If you want to make such a screen yourself - feel free to ask questions :)</p> https://www.lexaloffle.com/bbs/?tid=45501 https://www.lexaloffle.com/bbs/?tid=45501 Sun, 28 Nov 2021 14:23:36 UTC
