Day 2 - Researched SD card reading on the Arduino platform. This one took waayyyy too long - once I realized the native arduino SD library doesn’t support my >32GB exFAT microSD I spent the entire day looking into and testing various libraries.. turns out it was a hardware problem. I was using custom pins for SPI instead of the standard ESP32 VSPI pins and assumed it would work the same. Guess I chose a bad pin?
