tttapa·10mo ago·August 19, 2025**Added support for version 3.3.0 of the [arduino-esp32](https://github.com/espressif/arduino-esp32) core**: The Bluedroid-based Bluetooth stacks for all boards except the original ESP32 have been replaced by NimBLE-based stacks. For these configurations, Control Surface now automatically switches to the `ESP32NimBLEBackend` for [MIDI over BLE](https://tttapa.github.io/Control-Surface/Doxygen/db/d99/md_pages_MIDI-over-BLE.html). More details about the migration from Bluedroid to NimBLE can be found in https://github.com/espressif/arduino-esp32/discussions/10991. **Full Changelog**: https://github.com/tttapa/Control-Surface/compare/2.0.0...2.1.0
tttapa·1y ago·April 27, 2025💥 Breaking changes w.r.t. version 1.2.0
- ([7bd5268](https://github.com/tttapa/Control-Surface/commit/7bd5268fe8906ba4fbd01024fbddc8598ffd9eb3))
- The `pin_t` type is now a distinct type rather than an alias to an integer.
- This improves type safety, because `pin_t` is no longer implicitly
- convertible to an integer (although integers are still convertible to
- `pin_t`), and it is no longer possible to accidentally use incorrect
- constructs such as `mux.digitalRead(mux.pin(0))`. A new type, `pin_int_t`,
- was added to represent sizes and offsets of pins (e.g. “the sixth pin of this
- multiplexer)”, and the argument types of the member functions of the

📋 Other significant changes
- MIDI parser and pipe staller overhaul (63d51ef).
- ESP32 3.0.0 compatibility and updates (806beca, 48c87ad, e9c06a2, 34334518, 6e2c3585).
- Full BLE MIDI support across multiple backends:
- ESP32 NimBLE and Bluedroid backend support, with security, privacy, async send improvements (59ac8ef, 7419b6c, 7209429, dc72207).
- BLE MIDI support for Raspberry Pi Pico W (e910569, 99c98cc, 01620b0, d7a4e69).
- Cleaner BLE backend abstraction and thread-safe ring buffers (6851687, 8aa7d3c).
- USB MIDI multi-cable support (up to 16 cables) on RP2040 (5f492cf).

tttapa·6y ago·January 15, 2020📋 Changes
- Shorter filenames for examples (Windows limitation)
- Small bug fixes and improvements
- Documentation improvements
- More examples
tttapa·6y ago·November 30, 2019This version adds support for Arduino Due and Arduino Nano 33. The directory structure has been improved, and some parts of the library have been moved to a separate repository, [Arduino Helpers](https://github.com/tttapa/Arduino-Helpers).
tttapa·6y ago·November 30, 2019This is the last version before changing the structure to use the [Arduino Helpers](https://github.com/tttapa/Arduino-Helpers) library.
