Two emulators are featured here, the first takes all images in a folder and shows them in sequence, as they would look on the spinning poi:
The second program receives RGB values from serial connected poi chip and displays on screen. This is showing what is actually being sent out to the LED strip, useful for testing – I was getting a bit tired of spinning the poi whilst programming them and the Android transmitter app at the same time.
The image below is of the computer generated default offline patterns, but if wifi sent images are available it looks somewhat similar to the above. Colour is not yet optimized.
For the serial sending to work on the poi, a fairly large change in code is needed. The serial necessarily slows everything down drastically, so it’s for testing only.
