Anyone working on support for the new Raspberry Pi Pico?


#1

Seems like a nice platform for running ulisp :)


#2

It’s an M0, so presumably it’ll be easy enough to add as soon as someone makes an Arduino core for it.

It looks purpose-built for UF2 and MicroPython, though.


#3

arduino themselves are already working on porting the arduino core to the rp2040 chip :) https://blog.arduino.cc/2021/01/20/welcome-raspberry-pi-to-the-world-of-microcontrollers/


#4

Lukas Rusak is independently developing an Arduino core for the Raspberry Pi Pico:

However, it doesn’t yet seem to be developed enough to serve as the basis for porting uLisp.


#5

Adafruit’s Feather-style Raspberry Pi Pico is now in stock:

As well as being compatible with Feather add-ons, the main advantages over the Raspberry Pi Pico are:

  • Pin legends you can read from the top of the board.
  • 8 MB SPI flash, which uLisp should be able to make use of.
  • An RGB NeoPixel (yawn).
  • A STEMMA QT connector for easy connection to suitable I2C sensors.
  • A USB C connector.
  • A LiPo battery connector.

Not for long, I suspect.

#8

Looks pretty good. Assuming Arduino are also working on a core to support their RP2040 board, does this mean that there will soon be two alternative cores?


#9

I’m not sure how long hobby development will continue on these BSPs once Arduino release their official one :D


#10

BSP meaning?


#11

I assume ‘board support package’, which is essentially the same as what Arduino calls ‘cores’. That term is used by most of the manufacturers.
