• Description:
In another video we wrote firmware for the ESP8266 that allowed us to upload files to the Flash File System (SPIFFS) over HTTP reducing the time taken by this process (youtu.be/QLGwI5tC9yk). To upload the files we used the command-line utility *curl* to do so.
In this video, we modify the index file that is served, so that it accepts drag-and-drop files and uploads them to the Flash File System. This allows us to use a browser instead of *curl* for uploading the files. After these changes we upload JPEG images, connect a 16×16 WS2812/NeoPixel matrix to the ESP8266, and write firmware that allows the chip to display them.
