The PicoMite is a Raspberry Pi Pico running the free MMBasic interpreter.
MMBasic is a modern Microsoft BASIC compatible implementation of the BASIC language with floating point, integer and string variables, arrays, long variable names, a built in program editor and many other features.
Using MMBasic you can use communications protocols such as I2C or SPI to get data from a variety of sensors. You can save data to an SD card, display information on color LCD displays, measure voltages, detect digital inputs and drive output pins to turn on lights, relays, etc. All from inside this low cost microcontroller.
This is a port of the BASIC that’s used on the Maximite virtual retro computer platform, which means that there are many working examples out there for you to crib from, and even a forum. Add in the incredibly nice user manual and tutorial (PDF), and you’ve got the perfect weekend afternoon.
The PicoMite firmware is totally free to download and use.
