pgmspace.h: No such file or directory for Raspberry Pi Pico

[ghost]

• Arduino board: Raspberry Pi Pico
• Arduino IDE version: 2.0.3
• Using Arduino Mbed OS RP2040 Boards (installed from Arduino's board manager) to program the Pico

The error I get when trying to compile the example file "ssd1306_128x64_12c" is the following:

Adafruit_SSD1306.cpp:42:10: fatal error: pgmspace.h: No such file or directory

Lines 39-42 of such cpp file looks like this:

ifdef AVR

include <avr/pgmspace.h>

elif defined(ESP8266) || defined(ESP32) || defined(ARDUINO_ARCH_RP2040)

include

If I modify line 42 like this:

include <avr/pgmspace.h>

then the sketch compiles and works as expected.

So it seems that the Pico uses the avr pgmspace, maybe this can be modified in the cpp file Thanks!

It works fine if you use version 2.5.1 fwiw:

lib_deps = 
    adafruit/Adafruit SSD1306@2.5.1

(Don't use the ^ symbol after the @ sign or it will use "a version compatible with 2.5.1" and it thinks that 2.5.2 and above are "compatible".)

Seems like https://github.com/adafruit/Adafruit_SSD1306/commit/3fb7221784be255fae7b4eba219039e398aed442 is at fault; they added support for the RP2040 Feather and somehow broke the RP2040 pico in the process.

Switching to 2.5.1 (from 2.5.7) worked for me to get things building, I feel lucky this was my first search result!

Hi Same issue for Arduino Nano ESP32 "Compilation error: avr/pgmspace.h: No such file or directory" Any workaround? Thanks
