Datasheet

Once it's loaded up, open up the REPL (and restart it with ^D if necessary) to get a printout of all the files included. We

recursively print out all files and also the filesize. This is a good demo to start with because you can at least tell if your

files exist!

import adafruit_sdcard

import busio

import digitalio

import board

import storage

import os

# Use any pin that is not taken by SPI

SD_CS = board.D0

# Connect to the card and mount the filesystem.

spi = busio.SPI(board.SCK, board.MOSI, board.MISO)

cs = digitalio.DigitalInOut(SD_CS)

sdcard = adafruit_sdcard.SDCard(spi, cs)

vfs = storage.VfsFat(sdcard)

storage.mount(vfs, "/sd")

# Use the filesystem as normal! Our files are under /sd

# This helper function will print the contents of the SD

for file in os.listdir(path):

stats = os.stat(path+"/"+file)

filesize = stats[6]

isdir = stats[0] & 0x4000

if filesize < 1000:

sizestr = str(filesize) + " by"

sizestr = "%0.1f MB" % (filesize/1000000)

print('{0:<40} Size: {1:>10}'.format(prettyprintname, sizestr))
