no matching function for call to 'SDClass::open(StringSumHelper&, int)'

I created a new lib dir and put all your files in a new folder.

I set #include "SD.h" to #include "mySD.h". But now I get:

I try to use the TTGO T8 V1.7 with https://github.com/mvoss96/LED-PIXELART-MATRIX but the SD stuff causes problems here :(

Invalid. The src code, which is loaded, set the var types to String. The patched SD lib could not handle it. Using the default SD lib from esp32 and Arduino solved it.
