Single-pixel images drawn on a 128x128 OLED by a 10-cent 32-bit RISC-V microcontroller.
Using a sine to binary 16 bit number generator I programmed those numbers into a pair of 2716 eproms to get the 16 bit wide sine number 'lookup table' or in this case 'conversion table'. It works incredibly well and my sine/cosine generator drives a large X/Y C.R.T. P.P.I. (Plan Position Indicator 'think radar'). The display has 64K of pixels and the memory storage has the feature of OR'ing old data with new data that will leave a trail behind any moving object. Best wishes on your project.
