Also try to start from a consistent baseline with a freshly formatted SD card, ensuring that it’s formatted using the FAT32 file system. Have a range of cards on hand, and don’t be afraid to try something new like rolling your own adapter made out of a standard adapter and some header pins. With that in mind, stay flexible and be patient. This varied between adapters and card types. I’ll be the first to admit that I haven’t exactly got a large amount of experience in using SD card adapters, but while going the through the process of testing different adapters and cards, I came across a few inconsistencies. As a gesture of improving international relations (or perhaps it’s just a personal weakness) I will spell it both ways, although I tend to lean towards adapter. Let’s not get hung up on the semantics of language usage. Whether you spell it adapter or adaptor, it means the same thing. SD card adapter or adaptor.įirst the elephant in the room. I've written this short explanation as part of the much larger book ' Raspberry Pi Pico Tips and Tricks'. SPI mode is perfect if we’re writing short amounts of data to a file (e.g. We can use SD cards in Serial Peripheral (SPI) mode which allows us to rely on easy to use SPI peripherals and libraries for communication. SD cards are great for storing logging and data from microcontroller projects that can then be read on a computer. To make this function practical we can use an SD card for expanding storage via an adapter. This is a useful function when using the Pico for tasks such as data logging. The Raspberry Pi Pico is a very capable device, but it lacks the ability to store sizeable amounts of data on the board.
