Is there any way to export data from a vexcode program into a file (like an array into csv file)? If so, how would you do so and what would that code look like?

Please, see these related topics for examples of saving files to SD Card from the program running on V5 brain:
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…
Not sure what you did there, only std::ofstream ofs; needs to be global
I just tried this in VCS and it works.
#include "robot-config.h"
#include <cstdio>
#include <iostream>
#include <iomanip>
#include <fstream>
std::ofstream ofs;
int main() {
if( Brain.SDcard.isInserted() ) {
// create a file with long filename
ofs.open("a_long_filename_debug.txt", std::ofstream::out);
ofs << "lorem ipsum\r\n";
ofs << "this was a test of a file with long file name\r\n";
o…
I’m currently working on using the SD Card in PROS and was wondering if there is a command that returns a boolean for if the SD-Card is connected. Similar to the vex:
The last example is for PROS, not VEXcode, but it has some useful information.
