Aka, a Simple Picture Frame for the M5Paper.
This project contains:
- The flip-pics M5paper firmware needed to iterate across the SDcard at regular interval
- A go app that performs resize, rotation and proper naming for the images. The firmware barely display images, with this application we perform all steps in order to render correctly. It also encodes image information in the filename that the firmware picks it up. Image names are encoded
basename_widthxheight_offsetXxoffsetY.ext.
Prepare a folder with all the images you want to display on the M5paper.
Use resizer.go to convert all those images to the appropriate format/size. You can use as output folder the SDcard directly.
$ cd resizer ; go run resizer.go -input ~/mypictures/ -output /media/sdcard/

This project is built for PlatformIO and can be deployed directly from the IDE by pressing Build and Upload from the PlatformIO tasks.
You can configure the refresh interval by modifying the
SLEEP_HOURSdefine.
NOTE when the cable is attached, the M5paper won't shutdown and you can iterate the images by pressing the side buttons.
