Performance Evaluation of C/C++, MicroPython, Rust and TinyGo Programming Languages on ESP32 Microcontroller

The rapid growth of the Internet Things (IoT) and its applications requires high computational efficiency, low-cost, low-power solutions for various IoT devices. These include a wide range microcontrollers that are used to collect, process, transmit data. ESP32 is microcontroller with built-in wireless connectivity, suitable applications. chip gaining more popularity, both in academia developer community, supported by number software libraries programming languages. While low- middle-level languages, such as C/C++ Rust, believed be most efficient, TinyGo MicroPython developer-friendly low-complexity beginners allowing coding. This paper evaluates efficiency available namely C/C++, MicroPython, TinyGo, comparing their execution performance. Several popular data signal processing algorithms were implemented these times compared: Fast Fourier Transform (FFT), Cyclic Redundancy Check (CRC), Secure Hash Algorithm (SHA), Infinite Impulse Response (IIR), Finite (FIR) filters. results show implementations fastest cases, closely followed while programs many slower than other Therefore, Rust languages when response time key factors, Python can less strict system requirements, enabling faster complicated development process.
