- Sun Nov 22, 2015 2:31 pm #34699 A bit of my mistake this time doing a typo : simply remove the ampersand in front of fs_info.

- Sun Nov 22, 2015 2:33 pm #34700 Removed the & symbol:

- Sun Nov 22, 2015 2:48 pm #34701 Maybe you should show your latest piece of code, because I don't understand where this "GetMeThatVar(String)::FSInfo" comes from. Is your "FSInfo fs_info;" a local variable ?

- Sun Nov 22, 2015 4:02 pm #34707 Finally figured it out.

What you said about it being local got me thinking.

Thank for bearing with me. Still trying to figure this stuff out.

Had to put

Code: Select all FSInfo fs_info;

at the top. Not inside the function.

Code: Select all#include "spiffs/spiffs.h"
#include <FS.h>


 FSInfo fs_info;


void setup() {
  // put your setup code here, to run once:
  SPIFFS.begin();
  Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:
  Serial.println(GetMeTheRemainingSpace());
  delay(1000);
}


String GetMeTheRemainingSpace()
{
  String MyOut;
  struct FSInfo {
    size_t totalBytes;
    size_t usedBytes;
    size_t blockSize;
    size_t pageSize;
    size_t maxOpenFiles;
    size_t maxPathLength;
  };



 
  SPIFFS.info(fs_info);
  int Flashfree = fs_info.totalBytes - fs_info.usedBytes;
  MyOut = String(Flashfree );
  return MyOut;
}
