This SmartMatrix Library example displays GIF animations loaded from a SD Card connected to the Teensy 3 using the SmartMatrix Shield
The example can be modified to drive displays other than SmartMatrix by replacing SmartMatrix Library calls in setup() and the *Callback() functions with calls to a different library
Wiring is on the default Teensy 3 SPI pins, and chip select can be on any GPIO (customize by defining SD_CS in the code). For Teensy 3.5/3.6 with the onboard SDIO, change SD_CS to BUILTIN_SDCARD
| Function | Pin |
|---|---|
| DOUT | 11 |
| DIN | 12 |
| CLK | 13 |
| CS (default) | 15 |
This code first looks for .gif files in the /gifs/ directory (you can customize this with the GIF_DIRECTORY definition) then plays random GIFs in the directory, looping each GIF for DISPLAY_TIME_SECONDS
This example is meant to give you an idea of how to add GIF playback to your own sketch. For a project that adds GIF playback with other features, take a look at Light Appliance and Aurora:
If you find any GIFs that won't play properly, please attach them to a new Issue post in the GitHub repo here:
