Support for RP2040

[vanbwodonk]

Hi, I'm using this for ESP32 and it works great!!

Just want to ask, is this library support arduino core for RP2040 ? (https://github.com/earlephilhower/arduino-pico)

Hi, I just compiled the example countPowerCycles against the arduino-pico on Arduino IDE without errors and with minimal changes to the EEWL library. I have no RP2040 boards, so I must stop here for now.

Thanks @fabriziop, i can help you to test, with my raspberry pi pico.

Ok, if you want to test, you need to edit file .../EEWL/src/eewl.h: add || defined(__arm__) at the end of the line marked with double asterisks as follows. Remember to compile with Arduino-pico.

` / macros /

ifdef EEWL_RAM

#define EE_WRITE( addr , val ) (buffer[(int)( addr )] = val)
#define EE_READ( addr ) (buffer[(int)( addr )])

else

#ifdef __AVR__
  #define EE_WRITE( addr , val ) (EEPROM[ (int)( addr )  ].update( val ))

**#elif defined(ESP8266) || defined(ESP32) || defined(arm)

define EE_WRITE( addr , val ) (EEPROM.write((int)( addr ),( val )))

#else
  #error ERROR: unsupported architecture 
#endif
#ifdef ESP32
  #define EE_READ( addr ) (EEPROM.read((int)( addr )))
#else
  #define EE_READ( addr ) (EEPROM[ (int)( addr ) ])
#endif
#include <EEPROM.h>

endif

try edit and compile with arduino-pico core, got this error
