These examples are cute, but this isn't a comprehensive collection. Not even close. Given that PIO's most compelling use case is replacing legacy MCUs, I find it disappointing that they haven't provided PIO boilerplate for the peripherals that keep those archaic architectures relevant. Namely: Ethernet MII and CANbus. Also, if RP2xxx is ever going to play ball in the wireless space, then they need an out-of-box Bluetooth HCI implementation, and it needs sample code, and integration into Zephyr. I speak as someone living in this industry: the only reason Nordic has such a firm grip on BLE product dev is because they're the only company providing a bullshit-free Bluetooth stack out of the box. Everything else about nRF sucks. If I could strap a CYW4343 to an RP2350 with some example code as easily as I can get a BT stack up and running on an nRF52840, I'd dump Nordic overnight.

Just feed the boilerplate templates to Claude and ask it to "write a CANbus driver, use boiler plate as example" and done?

  I have never had even the slightest luck getting any of the AI services to generate something as specialized as embedded system drivers.

Just pick whatever fits best in your application. No µC is going to solve everything for everyone. RP2350 is about the best I can think of for interfacing with legacy protocols. Well, short of using FPGAs anyways.

Well open source CAN and MII implementations do exist. Perhaps you can help provide a pull request to the official repo that checks in appropriate versions of that code, or file an issue requesting them to do it. https://github.com/KevinOConnor/can2040 https://github.com/KevinOConnor/can2040 https://github.com/sandeepmistry/pico-rmii-ethernet https://github.com/sandeepmistry/pico-rmii-ethernet My biggest issue with their wireless implementation is that I get my boards made at JLCPCB and Raspberry Pi chose a specialty wireless chip for the Pico W which is not widely available, and is not available at JLCPCB.

How much do those Nordic controllers cost? Are the as affordable as the RP2350?
