Was testing SdFat_Usage to see how to use the SdFat bytesPerSector() function and received this compile error:
Went back to TD1.56 release and the sketch compiled without error.
Tested with clean install of Arduino 1.8.19 and TD1.57B1 to 1.57B3 Ubuntu 20.04.
Has anybody else run into this?
Code:
SdFat_Usage: In function 'void setup()':
SdFat_Usage:122: error: call of overloaded 'write(char)' is ambiguous
myfile.write('\0'); // add a null byte to mark end of string
