A simple Arduino / FIGnition communication demo follows:
Arduino Slave
#include <SPI.h>
void setup (void)
{
Serial.begin (115200); // debugging
pinMode(MISO, OUTPUT); // MISO
SPCR |= _BV(SPE); // Slave Mode
} // end of setup
// main loop
void loop (void)
{
if(SPSR&SPIF) { //
print(SPDR);
}
} // end of loop
The arduino code is written as a standard sketch. Sketches always have a setup function
which performs initializations and a loop function which is executed repeatedly. Here,
setup simply activates the arduino's serial port; sets up the MISO pin to be an output (be-
cause we want it to operate in Slave Out mode) and finally enables slave mode. The ardu-
