Arduino as ISP
This comes up every now and then, placing it here for reference.
Here is results from burning a Sketch two different ways:
The sketch simply makes pin 12 of an Arduino Pro Mini go HIGH at power on time.
void setup()
{
pinMode(12, OUTPUT);
digitalWrite(12, HIGH);
}
void loop()
{
}
- Sketch uploaded using the Boot Loader
- Sketch uploaded using the Arduino as Programmer
That's 1,460ms versus 64ms difference.
i.e. ~23 times faster.
