Array member in a struct -- how to instantiate

Projects Programming
1

Hey guys, I'm making stuff. Here's my struct code:

typedef struct {
  unsigned int raw[100];
  int time;
} myThing;

myThing myThings[100];

I'm trying to instantiate members through the following:

for (int i = 1; i < len; i++) { // len is arbitrary, but always < 100
    if (i % 2) {
      myThings[index].raw[i - 1] = results.rawbuf[i]; // where results.rawbuf[n] returns an unsigned int
    }
    else {
      myThings[index].raw[i - 1] = results.rawbuf[i];
    }
  }

It compiles no worries, but seems to freeze up my boards, both Arduino Uno and Mega. When changed from a struct to global variables it also works no problems, but that approach isn't practical for what I want. In C++, I'd probably do this as a 2D vector of unigned int array and int, but I'm not sure how to do that in Arduino land.

I've tried RTFM, but can't find things either things this specific, or things that I can absorb information from.

My question is, is there anything blatantly wrong that I'm doing, and if so what? Or, is there an alternate route I can take (for example a 2D array of arrays and ints)?

Thanks.

You haven't got that much RAM.

100 things, each with 100 ints in it - that's 100 * 100 * 2 (an int is 2 bytes) - that's 20,000 bytes, or just short of 20KB. Not counting the rest of the struct.

About 10 times as much memory as the Uno has...

Hahahah I'm so not used to these little things.

Good to know it's something simple, appreciate the help guys.
