Program RPi Pico using Mbed library with Arduino IDE

I just did a deep dive and with some low level mods to the core Arduino pico libraries I got the 2 I2C ports working together via Wire and Wire1.

Just tested with 2 Wii nunchucks...

Once the two cores can be used via Arduino, this will be pretty cool as each core could handle one nunchuck.

Hmmm, I can feel a blog coming along to demo.

Very cool.

While trying to troubleshoot an issue with the pico-sdk and the Grove LCD, I ran into the Arduino IDE config for the Pico from the Tom's Hardware website.

There certainly is a push to get Arduino support with the Pico.

This is a very useful blog. Well done for solving.

I recall having similar type of mbed issues with the Arduino nano 33 BLE board simply because I did not understand the structure and syntax of mbed os. Once I got to grips with it, it became much easier.

It pays to read the documentation, in particular API reference (need to take note of OS version) https://os.mbed.com/docs/mbed-os/v6.9/introduction/index.html

Within the documentation there is a section "Program setup" which has a subsection "Advanced configuration". This will help customise settings for your Pico board - like change SDA/SCL pins etc.

Then apparently the technique to use multicore is to apply the "RPC - Remote Procedure Call" method. https://github.com/EmbeddedRPC/erpc/wiki#why-use-nxp-erpc-for-multicore-systems

Hi [mention:dc11ece8204f479e8dce2a47a33b20d3:e9ed411860ed4f2ba0265705b8793d05]

That's great that you figured out so much so quickly and thanks for posting. I think it would take me a lot longer. Hopefully Arduino will get the issues you found fixed and the documentation cleaned up soon. Nice that you got RTOS to work, that is something I want to get more familiar with as well.
