[TC-440] Blink_Nicla.ino compiles for Nicla Sense, but not Nicla Vision

[aliphys]

Background info

According to arduino/arduino-examples#47 there is a special Blink.ino for the Nicle Sense ME, which according to https://docs.arduino.cc/software/ide-v1/tutorials/getting-started/cores/arduino-mbed_nicla also applies to the Nicla Vision. This is called Blink_Nicla.ino.

It can be found in this repo here: https://github.com/arduino/ArduinoCore-mbed/blob/master/libraries/Nicla_System/examples/Blink_Nicla/Blink_Nicla.ino

Expected behaviour
I can compile the Blink_Nicla.ino sketch to both the Nicla Sense ME as well as the Nicla Vision

Current Behaviour
When the Nicla Sense ME is selected, IDE 2 compiles without error.

However, when compiling for the Nicla Vision, it fails to compile.

Error message is as below

Nicla Vision doesn't have the LED on external I2C controller, so it can use the normal blink. Best thing we can do is adding an #error directive when compiling Nicla_System library for Nicla Vision, so the error is more precise.

@facchinm So something like this?

#ifdef ARDUINO_NICLA_VISION
  #error "Run the standard Blink.ino sketch for the Nicla Vision"

[facchinm]

yup

What do you mean by it can you the normal Blink?
Q: It's there any reason why compiling is very slow for Vision? [using the latest Arduino IDE]
