Display GIF

[Leoirmin1]

It's possible to display a GIF in the GC9A01 using the library

did you find out how?

I used an inefficient way to display a GIF.

1.- First, you need convert the GIF into frames.
2.- Each frame of your GIF must be procesed with the image_converter script.
3.- Save the mpy modules in your microcontroller.
4.- I use this code to load and display the GIF

def display_image(folder_name,tft):
  """
  Load and display the images from the SD into the TFT.

  Parameters:
  folder_name(str): Name of the folder where the GIF frames were found.
  tft (object): TFT display object.
  """
  try:
    sys.path.append(f"/sd/{folder_name}")
    print("Folder added to sys.path")
  except:
    print("Can't add folder to sys.path")
  images = os.listdir(f"/sd/{folder_name}")
  images = [img.replace('.mpy', '') for img in images if img.endswith('.mpy')]
  images = sorted(images)
  print(len(images))

  show_images = []
  for i in range(len(images)):
    # Import the modules of the image
    module = __import__(f"{images[i]}")
    show_images.append(module)
    if ((i % 100 == 0) and i != 0) or (i == len(images) - 1):
      for img in show_images:
        tft.bitmap(img,0,0)
        # Delated the load images
      for img in show_images:
        del img  # Delete reference
      ver_imagenes = []  # Restart the list
      # Remove imported modules from sys.modules to allow freeing memory
      for module in images:
        if module in sys.modules:
          del sys.modules[module]
      gc.collect() 
  if f"/sd/{folder_name}" in sys.path:
    sys.path.remove(f"/sd/{folder_name}")
    gc.collect()

The code will crash if it has too many GIF frames due to the microcontroller memory being full.
