Interrupt pin on the RP2040 Connect

Official Hardware Nano Family Nano RP2040 Connect

I need an IMU for a project I am working on. Initially tried to use the built-in IMU in the RP2040 connect. That works but the API seems too primitive for my needs. Consequently, I am thinking of using an external IMU, the MPU6050, which is an I2C device.

See this example: Build a Digital Level with MPU-6050 and Arduino | DroneBot Workshop

In order to use the MPU6050, I notice from sample code that the MPU6050 uses the INTERRUPT_PIN (ie digital pin 2) to indicate that data is ready. I would like to confirm that D2 is also the interrupt pin on the RP2040 Connect - thanks!

Ok, I think I have a more precise wording of my question after some more reading on the topic of interrupts for the RP2040 board.

I don't see the RP2040 Connect mentioned in the documentation for attachInterrupt(): attachInterrupt() - Arduino Reference

However, based on the similarities with the Nano 33 BLE, I assume that all pins can be used for interrupts so I will give it a try.

Hi,

Maybe Arduino recently updated this page but it is listed now based on the link you provided:

Nano RP2040 Connect all pins except A6/A7

Hope this helps-Brian

Thanks - As it happens, I did indeed try it out and it worked fine. But in any case, I'm glad the documentation has been updated.
