Uploading an object to a SDCard

[trontech569]

This is what’s known as serialization (and deserialization to pull the object back off the SD Card).

There is, as far as I and a quick Google can tell you, no way to do this without a little working using just the C++ standard library, but you can probably figure something out, even if not especially efficient, using an std::ios::binary fstream or you could probably also just find some code online to do the same thing.

How much programming knowledge do you have? This is either a relatively trivial task or a pretty daunting one depending on how well you know C++.

Whoa, hang on a second. You’re overcomplicating the problem a bit. It definitely is not the simplest problem though, I agree with you on that.

Because the OP placed his thread in the VexCode V5 Text Support, this is actually more simple than it might sound.

VexCode has SD Card commands that can be used to write to the SD Card.

This is the VexCode API that has an index of the commands.

And this is an example from JPearman

SD Card Help

Here’s a simple example showing how to use the VCS SD card save and load file API. This saves some information into a file called “test.h” on the SD card and then reads it back again. #include "robot-config.h" // storage for some information to save uint8_t myTestData[ 100 ]; uint8_t myReadBuffer[ 1000 ]; int main() { // set the test data to something detectable for(int i=0;i<100;i++) { myTestData* = i * 2; } // write test data to SD Card int nWritten…

Together, these should help the OP figure out how to do what they want.

Edit:
But this is not a beginner project for C++. If you aren’t very confident in C++, this probably isn’t the best thing to be working on.
