DroneBot Workshop
@dronebotworkshopAbout
Welcome to the Workshop! The DroneBot Workshop is the place where I work with Arduino, Raspberry Pi, ESP32, and lots of other cool microcontrollers, components, and sensors. This is a channel for learning and understanding. While I do build projects, most episodes focus on showing you HOW things work, so you can use the information to bring your own designs to life. Every video has a corresponding article on my website at https://dronebotworkshop.com , along with the diagrams and code samples you’ll need to build your own creations. You can also participate in discussions on my Forum at https://forum.dronebotworkshop.com. Please note that I no longer do any sponsored videos, enquiries for these will be ignored! If you'd like to know more about me or the DroneBot Workshop you can read the FAQ at https://dronebotworkshop.com/about-dronebot-workshop/faq/ And if you have technical questions please ask them on the Forum. Welcome to the Workshop! I hope you enjoy your stay! Bill

ESP32 Boards Manager 3 for the Arduino IDE offers a wealth of improvements and new features, but it renders a lot of older code incompatible. Today, we’ll look at Boards Manager 3 and see the changes you’ll need to make to update your old sketches.

That was about the time that some of your older code, and a lot of the code I provided here in the DroneBot Workshop, started to fail to compile. Boards Manager 3 offers a wealth of improvements and new features, but it also has changed how many ESP32 APIs function. Some features have been removed and replaced with new features; some are the same but with different syntax or mandatory fields. This is not a minor update, and it coincides with the release of Espressif’s ESP-IDF Version 5.3, the “official” ESP32 development platform. Version 3 brings a lot of the power and capabilities of this complex development environment to the Arduino IDE. Version 3 also supports more hardware, including the ESP32-C6 and ESP32-H3 SOCs. Of course, I can’t cover all of these updates in one video, not even one that's 45 minutes long! Instead, I will focus on three major areas: I2S - The audio service supported by the ESP32. ESP-NOW - The ESP32 peer-to-peer networking service. LEDC - The LED Controller, also used as a PWM generator.
