Arduino-Pico

I just discovered that there has been a port to use the RP2040 in the Arduino IDE. Not official Arduino release...

https://arduino-pico.readthedocs.io/en/latest/

https://github.com/earlephilhower/arduino-pico

I've installed the Board configuration

I'm going to try to see if the examples work with the Pico and my SparkFun boards. Probably get to it later this week.

Thought others might want to try it out.

Hi Ralph, I don’t have a Pico yet but it looks like there is an official Arduino release in github now based on mbed: https://github.com/arduino/ArduinoCore-mbed/releases/tag/2.0.0 https://twitter.com…

Hi Ralph - that looks exciting! I'll be looking at it soon Neil

Yeah, I posted this link in another post, but I found the instructions from Tom's Hardware work quite nicely programming the Pico from the Arduino IDE. https://www.tomshardware.com/how-to/program-raspberry…

With what Ralph shows here and the Tom's Hardware link, I was able to get the Grove RGB LCD examples to work with the Pico:
https://www.seeedstudio.com/blog/2020/01/20/how-to-use-16x2-lcd-with-arduino-grove-lcd-rgb-backlight/

There is an issue with the 'pico-sdk' where it will not pick up the Text i2c address from the Grove LCD so I attempted to use the i2c bus_scan example from the 'pico-sdk' but that hangs if the Grove LCD is connected and powered on. I have filed an issue for this.

However I was able to use the Grove RGB LCD with the Pico using both MicroPython and the Arduino IDE. I'm sure there will be some limitations, but thus far it seems to be working fine.

Jon,

If you can usefully use the Pico from Arduino then I'm interested. All I need now is a Pico.

That's a great feature of Arduino-Pico - automatically going into storage mode when you upload. Although I do have that Reset button on my breadboard so I don't have to unplug and replug it when I use other methods like the Mbed library.

The nice thing is that you do not have to set Pico in storage mode and do not have to unplug and plug it back in. It does seem to this in the background though.

I tested this from a Raspberry Pi 4 to Raspberry Pi Pico with a Grove LCD via i2c.

I added it to my Arduino IDE last night. I hope to play with it soon. Thanks for the "heads up", ralphjy
