🚀 My First AI-Coauthored Blog with ChatGPT


Author: Shafeeque Olassery Kunnikkal | Category: Cyber Security, IoT, Penetration Testing, STM32F411 | 2 Comments

This post is the result of my first deep, hands-on experience generating a full technical article using ChatGPT!Together, we explored how to implement a challenge-response system on STM32, refine C code, modularize functions, fix compiler warnings, and prepare polished documentation. Along the way, I encountered not just technical hurdles (like sandbox download issues, expired file…..
