Why do I "NEED" a SD card?

Hello all,

A project I am doing on the side is redesigning my USB Propeller Dongle. But I keep having an argument with myself. I can not figure out exactly why I need a SD card, when this project is just to allow me to program, and somewhat test code anywhere.

So I ask you for some help, Do you think a SD card is necessary for what I want to do?

Thanks
TC

    We are not telepathic. We don't know what you want to do. So we cannot answer.

    What code to you want to test anywhere? If it needs and SD then so does you dongle!

    Yea, didn't think about that, that my question was a little vague.

    Then let me ask this, What do you (or anyone) use a SD card for? Excluding data logging.

    Sometimes it's a microSD but besides logging I use this in my Forth systems for serving up web pages and files such as text, images, pdfs etc. I can also load and run code from the card but the big use for it is for audio files as I have several projects which use it for this purpose.

    Even if you don't have an immediate use, it is a good thing to have put in the time to get a good working knowledge of file creation/reading/writing/logging etc. Adding audio playback can open up a lot of opportunities.

    See this is why I ask. I would've never thought of those examples. Thanks, I am going to keep the SD card.

    Keep the SD card. How else are you going to get the floppy disk emulation going on the Z80 emulators? !

    I use mine to run various programs stored on it. I've also done some simple data manipulation using SPIN, but it was a fun lark.

    When a project needs binary data, it is nice to be able to get it from the SD card, and if you use a filesystem, not just blocks, the data can be updated on the card easy with a PC.
