Redefinition of the F() macro

[cpm64]

Hi there,

I would like to know what is the reason of redefining the F() and __FlashStringHelper macros in DIO2.h (non AVR branch)?

In some cases this will break the compilation:

myFunc(const __FlashStringHelper*, ...)

Cheers

Hi,
You are right, this is probably a legacy of old Arduino non AVR platforms I have used at that time. Probably not necessary anymore. Does it work if you remove the lines in your case ?

Hi,
Yep, working on both ESP32 and 8266, just removed the 'offending' lines:

#ifdef F
#undef F
#endif

#define F(str)	str
#define __FlashStringHelper		char

Removed #include <Arduino.h> as well, however in my case I include this in another header.
