Pinout for feather rp2040 and micro sd breakout

Post by Tom_d »

Can someone confirm the ideal pinout for max speed IO for the new rp2040 feather and the micro sd breakout for circuitpython?

In the walkthrough for aruidino is really comprehensive and the explanations pretty good in the tutorial but I just want to make 100% sure I'm fully optimizing the IO for data transfer.

Appreciate you all.

Are you having getting SDCARDIO (the faster way) going with the RP2040?

https://learn.adafruit.com/adafruit-mic ... io-3119669

You can try this example code from the CircuitPython github issues. It can help specific Feather RP2040 pinouts.

Code: Select all

import board
import busio
import sdcardio
import storage

print("Files on SD Card:")

sd = sdcardio.SDCard(busio.SPI(board.GP6,board.GP7,board.GP4), board.GP9)
vfs = storage.VfsFat(sd)
storage.mount(vfs, '/sd')
print(os.listdir('/sd'))
