Make Your own a Retro traditional Computer Using Only STM32F103C8T6 Arduino Like | VIDEO PART 2
A complete #BASIC_interpreter for the #STM32DUINO, using a PS/2 keyboard, and SPI #TFT_Screen. The BASIC supports almost all the usual features, with float and string variables, multi-dimensional arrays, FOR-NEXT, GOSUB-RETURN, etc. Saving and Loading from EEPROM is supported, as well as auto-running a program on power-up. You can also read and write from the analog and digital pins.
There's about 64 KB of RAM available for your BASIC programs and variables, so its roughly equivalent to first computer ( ZX81). The other 20 KB of RAM (on an #Stm32duino) is used for the keyboard and screen buffers, with a small bit of room left for the CPU stack. That works out quite well, since there's a 64 KB EEPROM on the STM32F103C8 so if your program fits in the basic environment, it will fit when saved to EEPROM!
