Convert Serial Bytes to Float in Embedded C with Unions and Endianness

This article explains how to reconstruct a 32‑bit floating‑point value from four serial bytes in embedded C by using a union or struct overlay, demonstrates the code, shows the resulting little‑endian byte order, and provides a simple function to detect system endianness.
