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.

@op8 sorry for the late reply, thank you very much, i still love it to watch the price on it. The M5 core is the regular black framed M5-core and the bottom is the M5GO/FIRE Battery Bottom Charging Base SKU:A014 from this M5-Stack-Shop (do not forget to buy the chargning base plate as i did, these are 2 seperate items to buy) It has the rgb-led strip built-in but it is only barely used in my code.. My Intention was to show major price movements with red/green flashing lights (and sounds) for example. Unfortunately i did not implement more functions since then.
A little problem i have experienced is the wake-up behavour on usb-cable because with the battery base it behaves different as it is with standart battery back. But this can be solved in the code if you change the settings at //Power Settings
