Actually, there is no background process running on the Arduino; the Arduino is put back into program (boot-loader) mode by pulsing the DTR line from the host computer, which does a hardware reset of AVR. There is a timer interrupt at 1 kHz, but that uses very little CPU (less than 1%); the PWM outputs are also done using timers, but via hardware on the chip, so no instructions are executed. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
