I've just started initial forays into the world of a Kerbal SimPit, and I'm quite excited by it all, especially after finding that the previous serialIO plugin was no longer supported, but that this one was in development - hurrah! I've poked around with arduinos before, but nothing of any great significance, and I suspect that is where I'm coming unstuck. I've hooked up a small OLED panel to display the altitude and apsides messages, and an 2812 LED bar to show the state of the action groups. Either on their own work fine, but if i have them both enabled then the arduino crashes, restarts, and never quite connects properly again. My first thought was a memory issue, but it seems to have enough spare. Second thought was a conflict between the OLED and the LED, but running them both on a separate sketch with no simpit seems to work, even with a serial write function.
Code is as follows:
#include <KerbalSimpit.h>
#include <Adafruit_NeoPixel.h>
#include <Adafruit_SSD1306.h>
#define OLED_RESET 4
Adafruit_SSD1306 display(OLED_RESET);
#if (SSD1306_LCDHEIGHT != 64)
#error("Height incorrect, please fix Adafruit_SSD1306.h!");
#endif
#define LEDPIN 6
Adafruit_NeoPixel strip = Adafruit_NeoPixel(16, LEDPIN, NEO_GRB + NEO_KHZ800);
int XPin = A0;
int YPin = A1;
int XValue = 0;
int YValue = 0;
int XGame, YGame;
int displayAltitude;
long displayApsides;
KerbalSimpit mySimpit(Serial);

Can anyone see something blindingly obvious that I'm doing stupidly (or rather, that would cause problems, no doubt there's lots of stupid stuff in there). Similarly if there is a better place to post queries please just shout
TIA!
