Adafruit HUZZAH32 compatible with ESP32 IDF?

[PaulELong]

I'm building a project using the ESP32-IDF (not Arduino). It's working on a Hiletgo ESP32S driving an OLED screen and communicating via BLE. The advice on Adafruit's website seems to indicate it's tested for Arduino IDE and says "with a USB interface that lets you quickly use it with the Arduino IDE or the low-level ESP32 IDF". I like the integrated battery of Adafruit, so I want to know if it should be easy to run my app on the HUZZAH32 hardware with my current project that doesn't use Arduino? Besides, isn't Arduino just C++ behind the scenes, so what could be different?

Anybody have advice?

Thanks, Paul

You certainly CAN use the Huzzah32 as a platform for native ESP-IDF programs. You have to pay attention to I/O pin definitions, since you don't have a definition for them within the IDF itself. You can grab them from the Arduino code, or just use the pinout diagrams from the Adafruit site (https://learn.adafruit.com/adafruit-huz ... er/pinouts). For example, you'll need to set BLINK_GPIO to 13 to use on-board LED in the blink example program. That's an option to change in via 'idf.py menuconfig'.

Easy-peasy. I've been using these with various IDF versions for over a year now. No problems at all, since Arduino is really just a thin layer atop the IDF.

Thank David, that's great to hear. Suppose the info on their site might be old or incorrect so it's good to see somebody has it working sucessfully.
