Hey, I'm the author of the pico-setup-windows installer mentioned in this article (and in the RP2040/Pico Getting Started Guide.) Just dropping a note here to say that if anyone has issues with that installer, please open an issue on https://github.com/ndabas/pico-setup-windows, I might not see all of the comments on this page.
Thanks SparkFun, I've been a big fan over the years!
Note that the WS2812 Control Python script in the MicroPython Examples has the red and green reversed. I updated mine to: ar[j] = g << 16 | r << 8 | b and it works as expected.
Also thanks for a great little board!
Good catch... sorry, I must have been thinking RGB LED at the time. I just updated the example code to reflect the color sequence properly.
Usually, we can found a Graphical Datasheet in the Documents section (for example... Pro Micro - RP2040, Pro Micro - 5V/16MHz, ...) that is useful quick guide to locate the functionality of the external header pins, and also for internal devices routing too as for example the WS2812 RGB LED. I don't know why it has not been done for this board. The "RP2040 datasheet" is the base point but Sparkfun implements aditional functionalities that should be very clear with the typical Graphical Datasheet that we, the Spark funnies, are used to using. Plase, do it.
Currently, we haven't built one due to the fact that the Arduino IDE only supports the Raspberry Pi Pico in the board manager. We haven't been able to add our boards as of yet.
Can we get a pinout diagram of what each of the numbered GP pins are capable of? I.E. which pins can do SPI tasks, i2c tasks, uart, etc?
Please refer to the RP2040 datasheet; specifically, section 1.4.3. GPIO Function.
hello, i can't wait to get mine!
I have a question about the Power Control circuit, why use a MOSFET instead of a Schottky diode?
I don't see how that could work; however, if you can explain your design/thinking... I'd be happy to forward that information to the engineering team.
Update: Ahh... I think you might be referring to using a Schottky diode between the battery voltage and the input voltage to the LDO regulator (where the drain and source for the MOSFET are connected). Maybe the engineer can chime in on that design choice. My guess is that the MOSFET method absolutely prevents reverse current into the battery and possibly creating an over voltage/charge problem.
Can't wait to play with this, also you are awesome
