Testing SBUS & PPM Signals on DIY STM32 RC Transmitter

Introduction

Welcome to DIY TECH DEEPLY! In this comprehensive guide, we'll delve into the intricacies of building and testing SBUS and PPM signals on a DIY STM32-based RC transmitter and receiver system. From understanding the underlying concepts to practical implementation and testing, this guide will equip you with the knowledge and skills to optimize your remote control setup for precision and reliability.

How It Works:

Before diving into the technical details, let's understand how SBUS and PPM signals work. SBUS (Serial Bus) is a digital protocol used for transmitting control signals between RC transmitters and receivers. It offers high resolution and low latency, making it ideal for demanding applications such as drone racing. PPM (Pulse Position Modulation), on the other hand, is an analog protocol that encodes multiple channels within a single signal by varying the position of pulses. While PPM is simpler than SBUS, it's still widely used in RC applications.
