ESP32 Forum

I tried the sample spi code in ESP32, there i created one .cpp file extra and called the spi operations in that new .cpp file, i added spi.h with that file so spi functions are working, like that i need to add gpio and uart part in new .cpp file, for that which header file i need to add, with out any header file it is showing error

This seems to be an Arduino issue, I moved it to the appropriate subforum.
