I'm trying to build a wireless doorbell chime to use with my smart home setup and the first step is trying to get sound. I have a Wemos D1 mini v4 that I'm using as the base. I'm attempting to use the ESP8266Audio library for audio, and I'm attempting to use the example sketch to play an audio file from SPIFFS. I have the audio file in the /data folder, and the sketch compiles and uploads correctly to the D1 mini. When running though I get the following output:
You mention uploading the sketch, but don't say anything about uploading the filesystem. So, I'm guessing you didn't. The easiest way is to use the Arduino ESP8266 filesystem uploader.
