| Several programming models for IoT script programming are available. Depending on the hardware model used (SoC or OS-based MCU), it may involve single script execution (e.g. Raspberry Pi Pico RP2040, Edge-class IoT) or multithreaded, parallel, multiple scripts, doing multiple tasks (e.g. Raspberry Pi 4, Fog-class IoT). The idea and model of the scripting programming for SoC class devices (edge) were presented in the chapter [[en:iot-open:introductiontoembeddedprogramming2|Script Programming with Middleware]].\\ In the case of far more powerful, Fog-class IoT devices that are OS-based devices, a variety of programming languages and, thus, scripting interpreters are available. | Several programming models for IoT script programming are available.
