I'm using Arduino Uno and Adafruit Wave Shield, with the WaveRP library. I was able to run the example programs of the waveRP library, but I try to connect a mic to the shield, didn't go well, so I returned to one of the examples to verify if the shield was working well and now is showing me this error message. I damaged the shield?

    No, you didn't break the shield. That is a software error - a problem in your sketch. If it's an unmodified example maybe you need to reinstall the library. – Majenko Jul 6 '17 at 21:46

    @Majenko I reinstalled both libraries the SdFat one and the WaveRP, but it keeps saying the same – Egm Jul 7 '17 at 0:33
