I was having a Raspberry Pi Zero sitting on my desk for a long time, searching for something to do with it. I also wanted to to learm STM32, mainly DMA and interrups. As the caculator is powered by an STM32F412, why not put them together ?
The idea was to add an application on the calculator, which will display the output of the Raspberry Pi, and send keystroke from the keyboard to it.
I have already used fbtft on a Raspberry Pi to drive a display over SPI, and the NumWorks has some pads exposing an SPI bus, so this should be easy !

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
