not really a bug but documentation has missing pages

[benwadub]

hello, while looking for information on midi callback I saw that some pages are missing, by exemple here

• https://tttapa.github.io/Control-Surface/Doxygen//home/runner/work/Control-Surface/Control-Surface/examples/examples.dox#custom-note-led-input-element-callback-fastled]
  here too
• https://tttapa.github.io/Control-Surface/Doxygen//home/runner/work/Control-Surface/Control-Surface/examples/examples.dox#autotoc_md10note-fastled-colormapper

Thanks for the report! This seems to be a bug in https://github.com/doxygen/doxygen. I didn't immediately find a workaround: no matter what I try, absolute or relative paths, the resulting path in the Doxygen search is corrupt for some reason.
I'm quite busy at the moment, but I'll try to open a bug report at some point.

no problem, I have lot of pain to understand how I can use the midi callback I manage to receive to be able to make my neopixels strip act as a led ring
here is the code to call midi data but after I don t know how to use it with fastled if you can point me in the direction to learn?
the goal is to have my 16 encoders of another sketch to be coupled with neopixels rings

#include <Control_Surface.h> // Include the Control Surface library
// Define the array of leds.
Array<CRGB, 8> leds {};
// The data pin with the strip connected.
constexpr uint8_t ledpin = 2;

// The MIDI over USB interface to use
USBMIDI_Interface midi;
 

// Custom MIDI callback that prints incoming messages.
struct MyMIDI_Callbacks : FineGrainedMIDI_Callbacks<MyMIDI_Callbacks> {
  // Note how this ^ name is identical to the argument used here ^
 
  void onControlChange(Channel channel, uint8_t controller, uint8_t value,
                       Cable cable) {
    Serial << "Control Change: " << channel << ", controller " << controller
           << ", value " << value << ", " << cable << endl;
  }
  void onProgramChange(Channel channel, uint8_t program, Cable cable) {
    Serial << "Program Change: " << channel << ", program " << program << ", "
           << cable << endl;
  }

  void onSystemExclusive(SysExMessage se) {
    Serial << F("System Exclusive: [") << se.length << "] "
           << AH::HexDump(se.data, se.length) << ", " << se.cable << endl;
  }
  void onTimeCodeQuarterFrame(uint8_t data, Cable cable) {
    Serial << "MTC Quarter Frame: " << data << ", " << cable << endl;
  }
  void onSongPosition(uint16_t beats, Cable cable) {
    Serial << "Song Position Pointer: " << beats << ", " << cable << endl;
  }
  void onSongSelect(uint8_t songnumber, Cable cable) {
    Serial << "Song Select: " << songnumber << ", " << cable << endl;
  }
 
  void onClock(Cable cable) { Serial << "Timing Clock: " << cable << endl; }
  void onStart(Cable cable) { Serial << "Start: " << cable << endl; }
  void onContinue(Cable cable) { Serial << "Continue: " << cable << endl; }
  void onStop(Cable cable) { Serial << "Stop: " << cable << endl; }
  void onActiveSensing(Cable cable) {
    Serial << "Active Sensing: " << cable << endl;
  }
  void onSystemReset(Cable cable) {
    Serial << "System Reset: " << cable << endl;
  }
 
} callback;
 
void setup() {
 
 
  
  Serial.begin(115200);        // For printing the messages
  midi.begin();                // Initialize the MIDI interface
  midi.setCallbacks(callback); // Attach the custom callback
}
 
void loop() {
   Control_Surface.loop();
  midi.update(); // Continuously handle MIDI input
