I'm having a new issue with my sampler pedal project. Previously, it would work fine (though with some noise, which is a whole other issue) when connected by USB to my laptop, but wouldn't launch when connected to a separate USB power supply. I narrowed it down to it failing at:
It has the same issue with the example code. Now, it fails even when connected to my laptop. I tried re-formatting (FAT32) and reloading the SD card, but it simply won't launch. Is there a chance there's a hardware issue with one board or the other, or with the soldering job (looks fine, but I haven't tested continuity yet)? The SD card works fine when plugged into any other device.
Code:
if (!(SD.begin(SDCARD_CS_PIN))) {
while (1) {
// Serial.println("Unable to access the SD card");
displayE();
delay(500);
}
displayZero();
}
