Hack of the day: scrolling text
I did a quick hack today and wrote a scrolling text app for an Adafruit 8×8 LED display I had lying about:
The app is written in C++ using the Intel
mraa I/O library (which looks pretty good) and running on a WRTNODE MIPS dev board with OpenWrt. The interesting bit is the text rendering: I started with a 6×8 bitmap font then added automatic width detection, blitting for rendering to the buffer, and blitting for rendering a scrolling window on the buffer to the display.
The next step is to add a web app so you can post messages from the Internet. What could go wrong?
