So, I tried a 3rd attiny85, I uploaded the blink program twice successfully. Then, without touching any wires except for disconnecting the LED leg from pin 0, I uploaded the fade sketch, then got the same error. I can't load anymore sketches to the 85, so apparently something in the fade sketch is causing the error...I don't know enough about the actual behind the scenes stuff, does anything seem potentially fatal in this code? I've used it on my uno as is, just with a different pin number.
/*
Fade
This example shows how to fade an LED on pin 9
using the analogWrite() function.
This example code is in the public domain.
*/
int brightness = 0; // how bright the LED is
int fadeAmount = 5; // how many points to fade the LED by
void setup() {
// declare pin 9 to be an output:
pinMode(0, OUTPUT);
}
void loop() {
// set the brightness of pin 9:
analogWrite(0, brightness);
// change the brightness for next time through the loop:
brightness = brightness + fadeAmount;
// reverse the direction of the fading at the ends of the fade:
if (brightness == 0 || brightness == 255) {
fadeAmount = -fadeAmount ;
}
// wait for 30 milliseconds to see the dimming effect
delay(30);
}
