ProMini with Adafruit 10DOF board problem

Projects Programming
1

Hi all,

I was running this sketch on my Uno with no problem, but I've switched to the ProMini as the next part of my project and when I view the serial output, it just keeps outputting "AdafruAdafruAdafruAdafru", wondering if I should have modified anything to get this sketch working on the ProMini or perhaps I've damaged the 10DOF board? Thoughts?

Thanks!

Sounds like your sketch is crashing repeatedly. Perhaps there is a power problem? How are the memory statistics? How much free SRAM is available?

Thanks John,

I'm powering via the FTDI, which is essentially 3 devices running off USB power (FTDI, mini, 10DOF). Doesn't seem like it should be too much of a load?

How would i check how much SRAM is free? I found this function, but I'm still quite uninitiated to programming and don't quite know how to use it:

int freeRam () 
{
  extern int __heap_start, *__brkval; 
  int v; 
  return (int) &v - (__brkval == 0 ? (int) &__heap_start : (int) __brkval); 
}

Is there a better (easier) way?

Thanks!

Figured it out. And I feel stupid.
The holes are labeled a little bit funky on the ProMini and I had power and ground wires soldered in the wrong holes. Amazingly it still functioned somewhat (lit up) and provided some serial data and I didn't fry it!

thx
