back to summary

The BlinkenLEDs Plus is a multiplexed display consisting of 144 standard LEDs (Blinkenlights resolution and aspect ratio) that can play movies from the ATMega16's flash memory or an RS232 MCUF stream, support for playing BLM- and BML-files as well as Blinkström Advanced BS2.BIN files from an SD card is planned.

Hardware

The hardware is built on two stacked veroboards (160x100 mm). The upper board contains only the LED matrix, wired in two planes on the solder side: the rows are connected directly on the board as usual while the columns' wiring stands out a few millimetres from the board. Wires connect it to the lower board which contains everything else (controller, row driver transistors, RS232 port, SD card etc.). I used an edge connector glued flat to the board for an SD card slot.

  • Schematic (you can leave out the SD card or the SD card if not needed)

Software

The software for the ATMega16 controller is written in assembly language and can be downloaded here. A perl-script that converts BLM files to assembly code (movies stored in the ATMega16's flash) is included.enthalten.
