WipperSnapper 1.0.0 Alpha 74 Pre-Release is Live!

Adafruit.io WipperSnapper 1.0.0 Alpha 74 is now live as a pre-release on GitHub!

Why are we releasing this as a pre-release before publishing next week?

This is a special release for those using ESP32-Sx devices with WipperSnapper. We’ve updated WipperSnapper to be built off the absolute latest version of the Arduino ESP32 core -V3.0. However, the official Arduino ESP32 version 3.0.0 is currently an alpha and includes potentially breaking changes.

We’d like to get this into the hands of people who actively use WipperSnapper and want the absolute latest firmware version. Internally, our WipperSnapper team will also be using this pre-release for their projects and builds.

What does this include?

For ESP32-x devices, WipperSnapper is now based on ESP-IDF v5.1 (release notes). At the time of writing, Espressif has released two versions of the Arduino ESP32 Core alpha v3.0.0 – alpha 1 and alpha 2. We’ve migrated our firmware to match the core API changes and updates for these alpha releases.

Breaking Changes in Alpha

  • Adafruit FunHouse ESP32-S2: The process for installing Alpha 74 on the FunHouse is different than the other boards since we’ve made the partition for WipperSnapper larger, and removed a partition for an OTA binary in the process.  The installation is currently for advanced users only. It will be the usual drag/drop install process for the beta release.
    • You will need to install the latest arduino-esp32 core from GitHub. In Arduino IDE, select “TinyUF2 No OTA” in the partition scheme menu and upload any sketch to the FunHouse.
    • Then, drag and drop the alpha 74 UF2 file to the HOUSEBOOT volume

How do I upgrade my firmware?

Visit the pre-release link for Adafruit WipperSnapper Alpha 74, find the UF2 file for your WipperSnapper Device, and drag/drop the UF2 file to your device’s DEVICEBOOT volume.

I found a bug! How do I report this to the Adafruit IO WipperSnapper Team?
