Happy Pi Day!!

13 Mar 2022

It's hard to believe that another year has gone by...

Happy Pi Day to the community. Hope that you can all find some moments of hope in the midst of the terrible events happening in the world.

I really don't have much time, but thought I should do something to celebrate Pi Day. I just got my latest RP2040 board - SparkFun RP2040 mikroBUS Development Board. A really nice RP2040 variant for datalogging sensors. It has a Mikroe Click socket, QWIIC interface, uSD card slot, LiPo battery support, plus 16MB of QSPI Flash.

There's a NeoPixel LED on the board, so I thought that it would be appropriate to run a "Blinky" as my first program on the board. So, here it is - using the Adafruit NeoPixel library and the Arduino IDE.

Not sure what type of requirements that you have, but for simplicity in life I normally use 32GB or less and the SPI interface. Most libraries will use FAT32 and Windows doesn't like to format FAT32 cards larger than 32GB. I don't usually have logging requirements that large.

The board looks like it was configured for 4-bit SDIO, but the one RP2040 library (using PIO) that I've seen will do 4-bit read and 1-bit write. I also don't currently have a requirement for high data rate logging, so I'm sticking with SPI which will limit the read/write speed. Hopefully, someone will get SDIO all working cleanly before I need it.

Nice little data logging board.

I am curious as to the SD card size and write rates.

Happy Pi Day to all!

I have an Arduino Nano RP2040 that I will be exploring some more in the near future.
