Keepin' It Real-Time
Before starting on a new embedded electronics project, one of the first decisions you'll need to make is choosing between a microcontroller and a single-board computer. To determine what you need, you’ll have to ask yourself a few questions. Do you need a full operating system, perhaps with multitasking and a desktop interface? What are the power constraints for the project? Do you need real-time precision?
The choice is usually clear, but sometimes the answer falls somewhere between the two options. If you need a multitasking operating system and real-time code execution, things get more complicated. Fortunately, Redditor Machinehum just built something that makes this situation easier to deal with. It is a Raspberry Pi HAT named RPI RTShield. It adds an RP2350 microcontroller and a few other goodies to a Raspberry Pi. It is something like an Arduino UNO Q for the Raspberry Pi ecosystem.
You've got perfect timing
