Video pattern generator for use with an Oscilloscope in mode X/Y/Z axis
Using a PIC24 @140MHz and its PWM channels for simple DACs
128x128 pixels @2bpp , 25 frames per second (can be extended of course)
Now added another version that can create Lissajous curves!
Further extension: PIC16 with real DACs added (though RAM is way too little to have "patterns" :) )
