Compile error - Arduino IDE - DaisySeed - Undefined reference

[Koemetstippen]

Hi, I'm a noob and like messing around with microcontrollers and music and would like to get the organ running on my DaisySeed. I'm using Arduino IDE with a DaisySeed. I read and applied the advice regarding compiler.libraries.ldflags=. This is is far as I got, errors of "undefined references" :

For example, in the main program there's DaisySeed_Setup() which is defined in the audio_module.h (and more like Audio_Setup, etc.). The errors are concerning the linking between both. I hoped the ldflags advice would bring solution but apparently not in this case.

My errormessage...

Do you know if one of these defines where active?
#if (defined ARDUINO_DAISY_SEED) || (defined STM32H7xx)
Usually, there are set by the Arduino IDE when compiling a specific board.
Which board library did you use? I think there are two different supporting the Daisy Seed.

[Koemetstippen]

The "ADUINO_DAISY_SEED" defines were probably not active. I messed around with your code and got it eventually solved when I deleted all #if (defined ARDUINO_DAISY_SEED) || (defined STM32H7xx) lines and also #define ML_SYNTH_INLINE_DECLARATION and #ifdef ML_SYNTH_INLINE_DEFINITION.

Then I continued deleting all lines that were not related to DaisySeed to make it easier for me.

I'm using the board library "STM32 MCU based board", and tried both the last one 2.8.1 and the 2.1.0. In the boards list I selected Generic STM32H7 series. Which library should I use ?

Some additional info....
I'm using a Daisy Pod from Electrosmith. It has a "normal" trs midi out. To make this midi work I added these lines...

#include <MIDI.h>
static DaisyHardware hw;
static size_t num_channels;
MIDI_CREATE_DEFAULT_INSTANCE();

void handleNoteOn(byte inChannel, byte inNote, byte inVelocity) {
Organ_NoteOn(0, inNote, 127);
Organ_SetLeslCtrl(127);
Organ_PercussionSet(CTRL_ROTARY_ACTIVE);
Organ_PercussionSet(CTRL_ROTARY_ACTIVE);
}

void handleNoteOff(byte inChannel, byte inNote, byte inVelocity) {
Organ_NoteOff(0, inNote);
}

Off course it's just note on/off, nothing more, but to me this is a great achieval. I'll continue trying adding stuff like pitch, reverb etc. Not easy for me but I got this far so...

I mainly use the standard midi connection in stead off the midi-USB. At this point I did not try or have experience with connection the DaisyPod via midi-USB. I'm going to but first I have to find my USB-host adapter.

I am very happy to hear about the progress. It might be possible that a define like ARDUINO_DAISY_POD might be set. This can be seen in the verbose output if it is activated.

I retried the original organ_example on my daisy_seed and it worked without changing anything. GREAT So no longer undefined references. I just added #define REVERB_ENABLE to get the reverb working. I also got the drawbars working by following one of your explanations on youtube. GREAT.............
I felt lucky so I continued trying the EPIANO. Here I got the "undefined reference" to ml_epiano.h I just felt letting you know this. I just read an issue about the epiano under #51

Thanks for everything out there.

Thank you very much for your feedback. I am very happy to hear that it works as intended. It is not so easy to maintain all projects with their complexity but its great when it works =)
