ESP32-S3 Box MIDI Pitch Bend Slider

The photo shows the ESP32-S3-Box with pitch bend slider connected to a MacBook. The MacBook is running receivemidi to show the MIDI pitch bend messages. The moire pattern and blue splotches are not visible to the naked eye. They are most likely caused by interference between the display and the camera.

Tested using Arduino IDE 1.8.19 and Espressif ESP32-BOX-S3-3

This is a simple example of using lvgl to create one slider on the ESP32-S3 Box display. Moving the slider sends MIDI pitch bend messages over USB. When the slider is released, the slider springs back to the center position.
