Hi, can M5Stack UNIT-LIGHT U021 connected to GPIO port of stick be used as a trigger? I'm searching a way to do photography of lightnings.

Hello Frank, thank you for allowing me to experience this wonderful project.
First of all, please understand that I am not familiar with the documentation format on GitHub.

A7R4, photo stacking The number of times the big button was pressed was the same as the number of shots.

I thought that if you press it once, it will shoot continuously even if you release your hand after that, and then press it again to stop shooting, but that didn't work.

(I don't know if the toggle hold function has already been implemented, but it doesn't work on the A7R4.)

(The same is true for the 9-focus function. While the big button is held down, the shooting proceeds by moving through the 9 zones in turn. If the button is accidentally missed in the middle, it goes back to the beginning and starts shooting from the center zone.)

I would like to suggest the toggle hold function of the Big Button and the setting of the total number of stacking shots as ideas.

(It would be nice if the shooting interval could be set as short as possible, but I think it will be difficult because there is a physical difference in the focus motor for each lens.)

Is your feature request related to a problem? Please describe.
I'd like M5StickC Plus to start recording gyro data when video recording is triggered (and stop recording gyro data when video recording is stopped) so it can be used for post-process video stabilization using Gyroflow.

Describe the solution you'd like
Many newer Sony cameras such as Sony ZV-1, ZV-E10, Sony FX30, Sony α7 IV etc. can record gyro data which are later on used for post-process video stabilization using Sony's proprietary software Catalyst Browse. However there's similar open source software called Gyroflow that can load data from external source and use it for video stabilization in a similar way Sony's Catalyst Browse does it. It'd be awesome to have such a small device as M5StickC Plus is, attached to older Sony cameras (such as Sony a6400 in my case) to achieve similar results.

Describe alternatives you've considered
Older Sony a6xxx series cameras (a6000, a6300, a6500) run on Android system and are tweakable (f.e. using this ) so maybe it could be possible to implement android app that would capture camera's internal gyro sensor data. However as far as I know, this is not possible for newer but not entirely new models such as Sony a6400 or a6600.

There's one specific Sony IR remote control that includes a "timecode reset" button, which you can use in a multi-cam setup to simultaneously reset all of the Sony cameras to the same timecode, synchronizing them. Here's a video. I believe this would be a great addition to Alpha Fairy, and would also help people get this functionality long after Sony stops manufacturing RMT-845 remotes!

I followed the steps on the site to install, at the end of the installation process the message appears on the arduino display:
ERROR!!!
Image File Missing
Please use the Arduino IDE
to upload the missing file

in the "Arduino IDE" application at the bottom of the upload log a message appears to do a hard reset via pin, but I have no idea what the pins are and how to do the hard reset (I can't find manuals).

Thank you

PS
I understand that the problem is that maybe I can't use ESP32FS tools?!
I mean, I'm using Mac and I never found the menu voice "ESP32 Sketch Data Upload", I just have upload to deploy...but no the menu voice you indicate in the steps.
I tried to instal the java plug in in all places:
Inside Sketchbook dir (where I have "arduino_workspace", "libraries" and I create "tools/ESP32FS/esp32fs.jar"....nothing
I tried to create "Documents/Arduino/arduino-esp32fs-plugin-master/ESP32FS/tool/esp32fs.jar"...no way

I have no idea how to do that...

SOLVED....Arduino 2.xx is not compatible with ESP32FS tool, need to use 1.8.19

Sorry for time loosing and again thanks for your work!

I'm trying to create a cost effective timecode syncing solution for my A7IV and my gopro.

Describe the solution you'd like
Most of the sony alpha cameras offer adding timecode to video metadata. You can set the "Time Code Preset" setting and have the time code run on "Free Run" which lets you use the built in timecode functionality. GoPro offers timecode encoding as well using their qr code functionality in the gopro labs firmware. The new sony camera remote SDK does offer a way to set the timecode preset using the sdk, and they offer the sdk for ARM. Would that ARM SDK work on ESP32? Once the timecode functionality works, it's relatively trivial to port the GoPro QR generation code which is available on their GitHub. Essentially we'd generate a time code on the alpha-fairy remote, which sets the "Time Code Preset" on the sony camera, and show a QR code for the GoPro at the same time. The QR code will keep updating as the timecode runs on the alpha-fairy, and thus both cameras (or any number of sony and gopro cameras) can be synced together.

Describe alternatives you've considered
The only real alternatives are the paid $500 timecode solutions, and the limitation with them is that they don't use the sony camera's metadata functionality. Instead they store the timecode data in one of the audio tracks. I think this solution may not be perfect (might be off by a couple of frames due to latency, but it would be a really cool solution if it's possible to implement.

I started digging into the SDK compiled files, and found this function which might be relevant:

/* PTPProxy3_0::SetTimeCodePreset(sony_lajiao::LjDeviceProperty*) */

undefined4 __thiscall PTPProxy3_0::SetTimeCodePreset(PTPProxy3_0 *this,LjDeviceProperty *param_1)

{
  char cVar1;
  undefined4 uVar2;
  uint uVar3;
  long in_FS_OFFSET;
  uint local_2c;
  uint local_28;
  uint local_24;
  long local_20;
  
  uVar2 = 0x8401;
  local_20 = *(long *)(in_FS_OFFSET + 0x28);
  if (param_1 != (LjDeviceProperty *)0x0) {
    cVar1 = PTPProxy::GetPropertiesSetValues
                      ((PTPProxy *)this,*(LjDevicePropertyCode *)param_1,&local_2c,0xc);
    if (cVar1 == '\0') {
      uVar2 = 0x8402;
    }
    else {
      uVar3 = (int)*(ulong *)(param_1 + 0x10) -
              (int)((*(ulong *)(param_1 + 0x10) & 0xffffffff) % (ulong)local_24);
      if ((local_2c <= uVar3) && (uVar3 <= local_28)) {
        uVar2 = (**(code **)(*(long *)this + 0x58))(this,0xd0d3,3);
      }
    }
  }
  if (local_20 == *(long *)(in_FS_OFFSET + 0x28)) {
    return uVar2;
  }
                    /* WARNING: Subroutine does not return */
  __stack_chk_fail();
}

And this is a screen grab from their SDK documentation:

After entering the cameras password into the Alpha Fairy, the UI goes straight back to the menu. The following is seen in the logs (once they're enabled)

Hi Frank,

Thank you for developing this repository. I'm curious whether you have experimented with Plus2, an enhanced version of M5StickC Plus2, notably featuring an expanded battery and increased flash storage.

Following the steps outlined in INSTRUCTIONS.md, I successfully compiled and uploaded to Plus2 using PlatformIO. Despite this, the screen remains unlit and there's no response from the device. Could you advise on a suitable approach to begin troubleshooting this issue? I would assume the issue came from the new dependencies used in the Plus2 library, involving the M5Unified. Your assistance would be greatly appreciated.

Best regards,
Sark

Hi thanks for all the incredible work on this. I thought about attempting to write this myself but if I could pay you to implement that would be incredible.

My request seems simple but I need a way to set a series of shots up to 12 and be able to change the settings of iso, shutter, and aperture on each shot.

I’m using it for custom bracketing for a very specific process

please let me know if this is something you could help implement

Great to see that compiling with PlatformIO is supported!

Is your feature request related to a problem? Please describe.
After cloning the repo and compiling with PlatformIO, a lot of changed files appear in the Source Control.

Describe the solution you'd like
Add to the end of file .gitignore:

#PlatformIO
.pio

to avoid showing up multiple changed files in the source control.

Describe alternatives you've considered
None
