Error compiling Firmata for board Arduino Nano Every about arduino

[pgrawehr]

Hi @ThorPrez

Please do the following: In the Arduino IDE, go to File->Preferences and enable verbose mode for compiling. Then run a build and copy the whole build output to a file. Attach this file here. The build output will contain the exact name of the preprocessor definition that is to be used.

Thanks for your feedback.
Where exactly can I see the right name for the board ?
Here are some examples of the output;

Arduino: 1.8.19 (Windows 10), Board: "Arduino Nano Every, None (ATMEGA4809)"

Using board 'nona4809' from platform in folder: C:\Users\Arbeitszimmer\AppData\Local\Arduino15\packages\arduino\hardware\megaavr\1.8.7
Using core 'arduino' from platform in folder: C:\Users\Arbeitszimmer\AppData\Local\Arduino15\packages\arduino\hardware\megaavr\1.8.7

Detecting libraries used...
.... mmcu=atmega4809 -DF_CPU=16000000L -DARDUINO=10819 -DARDUINO_AVR_NANO_EVERY -DARDUINO_ARCH_MEGAAVR ....

And here´s my edit:

// Arduino Nano Every
elif defined(AVR_NANO_EVERY) || elif defined(ARDUINO_NANO_EVERY)
#define TOTAL_ANALOG_PINS 8
#define TOTAL_PINS 24 // 14 digital + 8 analog + 2 i2c
#define IS_PIN_DIGITAL(p) ((p) >= 2 && (p) <= 21) // TBD if pins 0 and 1 are usable
#define IS_PIN_ANALOG(p) ((p) >= 14 && (p) < 14 + TOTAL_ANALOG_PINS)
#define IS_PIN_PWM(p) digitalPinHasPWM(p)
#define IS_PIN_SERVO(p) (IS_PIN_DIGITAL(p) && (p) < MAX_SERVOS) // deprecated since v2.4
#define IS_PIN_I2C(p) ((p) == PIN_WIRE_SDA || (p) == PIN_WIRE_SCL) // SDA = 22, SCL = 23
#define IS_PIN_SPI(p) ((p) == SS || (p) == MOSI || (p) == MISO || (p) == SCK)
#define PIN_TO_DIGITAL(p) (p)
#define PIN_TO_ANALOG(p) ((p) - 14)
#define PIN_TO_PWM(p) PIN_TO_DIGITAL(p)
#define PIN_TO_SERVO(p) (p) // deprecated since v2.4

It's the parameters prefixed with "-D" (excluding the D itself). So try

#elif defined(AVR_NANO_EVERY) || defined(ARDUINO_NANO_EVERY) || defined(ARDUINO_AVR_NANO_EVERY)

[pgrawehr]

Make sure you don't miss the # before elif

[ThorPrez]

With # before Elif I'm having more faults

[pgrawehr]

Then you probably have a syntax error. Try the line exactly as I specified above.

[ThorPrez]

#elif defined(AVR_NANO_EVERY) || defined(ARDUINO_NANO_EVERY) || defined(ARDUINO_AVR_NANO_EVERY)

It works, thanks.
Now I can try to communicate with Pi and Arduino. But it seems, that Node-Red cannot communicate with the Nano Every. Serial node is working, Arduino node not.

I have updated the source and after fixing the typo this works, so closing the issue.
