GIF playback with the STM32F411 BlackPill about arduino_gfx HOT 6 CLOSED

I have not yet tried STM32F411, did it works well on PDQgraphicstest example? Can you share the figures?

from arduino_gfx.

I changed the board to STM32F411CEU Blackpill and kept the example unchanged.

These are the errors.

The above code is under this preprocessor directive:

#if defined(ARDUINO_ARCH_SAMD) || defined(ESP8266) || defined(ESP32)

and should not compiled for STM32F4...

Right, I noticed this in the source code when trying the GIF example. There are many conditional statements in the source to include certain methods depending on what particular boards is used. I can try to grind through this myself, but I think it would be quite valuable to add support in this library for the STM32F4 chips. They should have enough power to play gifs like the ESP32, and I want to add a micro SD card to my project to store all Gifs/and jpgs. The microcontroller itself can be bought for ~2 USD on Taobao, which makes it a really great option for a product BOM.

I have just updated the ImgViewerAnimatedGIF example, please check is it ok now.

Hello!

The PDQgraphicstest example is now working, the GIF example has trouble with accessing the SD card attached on SPI bus1.
I have yet to find a good example for using the Blackpill with an SD card which is unfortunate. Seems to be a bit more of a struggle compared to other arduino compatible boards.

Thanks for your quick action to improve the library, I'm still blown away at the quality of pictures and gifs I can run on my display (at least with the ESP32 w/DMA, having some speed issues when accessing the GIF from SD)
