B4R Question ESP8266 PROGMEM error

[Mostez]

Hello,
I tried to upload this code example to ESP8266, but I got that error message below, is it about a missing file or is there another method for ESP to include arrays into progmem.

Thanks

PROGMEM is explained here: https://www.b4x.com/android/forum/threads/using-progmem-to-save-memory.71114/#content

This is an Arduino feature.

You can remove it quite easily.

1. Remove the #include line.
2. Remove the PROGMEM work.
3. Change the getData implementation:

#if C
B4R::Object beo1;
B4R::Object* getdata(B4R::Object* o) {
   return beo1.wrapNumber(data[o->toLong()]);
}
#end if

Thanks so much, worked OK. Sorry if it's a stupid question, data array stored in program memory or RAM?

Both. It is loaded into RAM when the program starts.

PROGMEM is useful when programming smaller Arduino boards that only have 2k or less RAM.
