Once the 12bit color was implemented, the next step was to add more memory, so that the processor can do some useful work. But it turns out the easy to use SPI memory provided only bottlenecks. With a maximum of 80Mbits / second transfer rate, it would be faster to do any planned processing on a computer with webcams. This has steered the project to the inevitable end of custom hardware, which I was hoping to avoid. Never-the-less, the aim to make it to a budget still remains. So, expect hardware updates to come...
