Connect an SD Card to your Raspberry Pi Pico Microcontroller Board using SPI 

Thank you! Finally I found a really simple explanation of how it all works. This video is great for hardware beginners like me. 👍🏻

Great explanation! I was confused on what adapter to get but this answered my questions.

I was just thinking that i needed to get sdcard support working on my pico last week. What a happy coincidence

*GARY!!!* Good morning Professor! Good morning fellow classmates! Stay safe out there everyone!

nice, expands the options for a pico webserver, much more local data available, could even have more than 1 sd card reader attached, just need a specific CS pin for each, the other wires are shared.

You can solder pin headers directly on top of a (full-sized) SD card, because the pitches are just correct. I often solder pin headers on Micro SD-to-SD adapters to make poor man's Micro SD card slots for my dev boards.

this was very helpful, thank you!

Brilliant now i can store more images for animations on a display

Great explanation, I have been into arduino but wanted to use arm for microcontroller. This is great stuff. Looking for adafruit kind of community build around your channel although I am also from software background but these things are fascinating to work on.

とても役立ちました。ありがとう！

How do you determine optimal spi frequency?

can i connect it with jumper wires straight to the raspberry pi pico?

Great Video! Worked perfectly. Thanks for sharing.

Yeah did exactly what you told to, but get this error: OSError: no SD card

On the pinout diagram, there are pins that are labelled equally (eg. 2 and 7, 4 and 9). Why is that and how do I choose the right combination (or does this not matter)?

Interesting! 🙌🏼🤔 Could the Raspberry Pi Pico be programmed to work like a Ch341a to flash bios to a laptop? Would you be able to make a video on how to do it if it’s even possible at all?

Thank you, this made it really easy

Good video! Do you try use the MMBasic to do this?

For the benefit of those of you still watching this in the 1980s, MOSI = Master Out - Slave In, and MISO = Master In - Slave Out. Slave is not a racist word, it's just a word.

I have 5 different SD cards and it does not work with 32 MB, 128 MB or 64 MB (MMC). I get the following error: `OSError: timeout waiting for v1 card` Although it does work with a 32 GB SD card

hi, maybe an obvious question, but what is the maximum capacity that the pico can support with de sd card?

thank you mr garyy

I see that your SD module is v1.1. I have a bunch of the 1.0 modules...Do you know what the difference is? Did they fix the issue of running MISO through the level shifter?

Got a bit of a tan there Gary 😂

What kind of speed will this offer? Can i store a movie clip and get a decent frame rate putting it to an ILI9486 TFT screen? 1 frame = w*h*bits per pixel = 340*480*2 (16bits per pixel) = 307,200 bytes per frame. So i need about 15MBps for 50fps 9.2 MBps for 30fps. Or am I just asking to turn my PICO into a tiny little cinder?

Is it possible to add a pen drive usb stick as a storage medium?

Could this be implemented to create a simple MP3 player?

One thing I find annoying about these SD interfaces is that they do not provide an interrupt when the SD card is inserted so you pretty much have to boot your board with the card inserted, which is annoying if you want to do quick debugging

Hey I would love if u would answer this question, my dad bought me a cheap piano a while ago, now it's OS has failed and I wanted to make a whole new hardware for it from raspberry pi pico, I was wondering if this will be possible, the piano has 54 keynotes which will require multiplexing based input (not analog), two speakers which should be driven by an amplifier and many customizable buttons. Please help me understand if I can implement the pico here

the pi foundation needs *milk-giving parent boards* that are fool-proof.

Hi, thank you for the great video! Do we need to mount the sd card everytime we turn on the pico? and do we have tou mount it just once? because if I run the code at min 12:29 more than once I get a "timeout waiting for response" error

me sd card has 3.3 input which does makes things a bit easier but I don't have many SD cards spare

hi can you connect it to a raspberry pi camera module 3?

What happened to the Speed Test G channel, Sir?

so we can write to a file, and read it back under the same name, but how do we get a directory of available files?

I'm new to the Pico. If I don't like soldering, can I plug a (USB stick) to an (OTG USB-A to micro USB adapter), and plug that into the Pico's USB port? Is there a library that will let the Pico to read / write to it?

Is the Speed Test G channel officially dead now?

Gary? This is mostly Off-topic, but I'd like your opinion on what, realistically, is keeping ARM from being more commonplace in the desktop space. I'm pretty sure the abundance of existing software built around x86 is a big part of it, but all the major operating systems in the desktop space will run on ARM now - or have versions which will, in the case of Windows. But the real big deal, I think, is more to do with hardware. As you go up in skill level, PC users are used to upgrading their storage, their GPU and RAM, and, eventually, their CPUs. Most ARM systems don't support this, and the ones that do are usually purpose-built for the server space. Systems that meet these qualifications and have an ATX-compatible form factor seem to just not exist. It can't be JUST the software that's keeping the corpse, the decaying husk, the veritable flesh-rotten zombie of a CPU instruction set architecture that is x86 around... can it?

I tried it but got the error "OSError: timeout waiting for v2 card" after creating the sdcard object with CS = machine.Pin(9, machine.Pin.OUT) spi = machine.SPI(1,baudrate=1000000,polarity=0,phase=0,bits=8,firstbit=machine.SPI.MSB,sck=machine.Pin(10),mosi=machine.Pin(11),miso=machine.Pin(8)) sd = sdcard.SDCard(spi,CS) # here the error occurs after some seconds Any ideas what's going wrong?

Why are you using VCC as VBUS instead of 3V3 (out) ?

What I did was grab a SD to mSD adapter, and soldered the wires directly onto the contacts. Popped in a mSD card, Presto

can i add a emmc in the sdcard place

Is there any error handling?

Something about programming a microcontroller in python just feels horridly wrong.

изза твоей программы мой esp32 безвозвратно завис и мне пришлось прошивать его заново

Will this work with a zero? my zero's reader has died

Where did you get this sdcard module? The github repo has been deleted

7:17 _"MOSI: main In, secondary/subnode In"_ In other documents you might find Master Out, Slave In.....

What will they think of next ?

Always enjoy your videos but was into this video to the point where you describe the SPI pins, where I thought “that is not what I’ve learned MOSI/MISO stand for.” What’s that, you say, you’re not wrong, just not done (explaining)? So, good on you for alluding to the prior words that ‘M’ and ‘S’ indicated and that Main and Secondary are the preferred, evolved terms. As someone in technology, I have observed some absolutely mental shouting matches through all communication channels when the C-level said “we ARE changing our terms to be more inclusive.” Acronyms are a huge pet peeve of mine especially when they can mean multiple things even within the same company, but the fact is they are all-wait for it-arbitrary and often time-specific. By that, I mean that it doesn’t matter WHAT we call something, only that at any given point in time we agree upon common terms to describe the same thing(s) for the purposes of articulating thoughts and ideas and to collaborate/compete across known landscapes. If at a point in time someone points out “hey, there is a better way to say X,” then that is just some of the change we are all promised to see throughout our careers and I am all for it as long as the messages of the change are widely disseminated and regarded, so that we can continue to communicate, collaborate, and compete. That some want to hold on to old ideas, words, acronyms, and backronyms, well those are issues for them to sort out while the rest of us continue forward.

M=Master and S=Slave; otherwise, very good job!

No more "Master/Slave" what a world. LOL.

The fact that comments appear about a tiny part of the video shows how controversial the master/slave main/secondary issue is. So rather than go with the new way which has loads of woke connotations, the best thing is to stick to the old fashioned way. Just because some shouty minority is saying something is the new and right way to say/do something doesn't make it the right way to say/do something. If Gary had stuck with master/slave no one would have said anything, no one would've noticed, and no one would've commented. Ahhhhhhh, I just worked it out, Gary deliberately said it to gain comments to help promote the video in RU-vid's AI. 🤣

MOSI / MISO forever. Damn the wokeness.

10 minutes wasted because we can;t be clear with MASTER OUT -SLAVE IN and vise versa. What a waiste of time
