I’m pretty excited because I managed to get an SD card working with the Pico. It is, shall we say, “hacky”. But it actually seems to work, so I’m happy. SD cards are a fussy old things, so getting it to work was rather labourious.
SD card raw example
Read SD cards on Pico. Compatible with Maker Pico out of the box.
Use spi interface ("spi1") as follows:
SCK GP10
MOSI GP11
MISO GP12
CS GP15
Limitations:
- file systems not supported, only raw data
- read, but not write, blocks
- single-block read, not multiblock
- version 2 cards supported, not version 1
- hard-coded spi pins
