LuckFox Pico Pro/Max Lab 9: RS232 Communication – Part 1: Hardware Conversion

In this first of two labs on RS232 communication, we explore the essential hardware aspects of serial signaling using the LuckFox Pico Pro/Max. This lab focuses on building and understanding BJT-based level-shifting circuits that convert between 3.3V UART and ±9V RS232 signal levels. These circuits are then tested by: ✅ Sending ASCII characters from the LuckFox to an oscilloscope to visualize proper RS232 signaling ✅ Running a loopback program where the LuckFox transmits messages to itself through the RS232 interface Understanding the hardware side of RS232 is critical for working with legacy instruments, industrial systems, and custom serial communication setups. This lab lays the foundation for software-level communication protocols, which we’ll cover in Part 2. 🔗 LuckFox Microcontroller Laboratory Course Page: https://www.darinulness.com/teaching/... 🔗 LuckFox Official Quick Start Guide: https://wiki.luckfox.com/Luckfox-Pico... 🔗 Fusion Automate: Setting up Ubuntu on the Pico Pro/Max    • Getting Started with LUCKFOX Pico Pro...   🔗 Lecture 1: Setting Up Python    • LuckFox Pico Pro/Max Lab 1: Setting u...   🔗 Introductory Overview to RS232 – RealPars    • What is RS232 and What is it Used for?   🔗 Introductory Overview to RS485 – RealPars    • What is RS485 and How it's used in In...   🔗 Overview of Communication Protocols – John S.
