RE: [AVR-Chat] clock speed

2007-06-24 by larry barello

Many AVR chips come factory programmed with internal 1mhz rc oscillator
enabled.  Those require an ISP frequency of 250khz or less to program.

You find the ISP frequency on the "board" tab of the STK500 dialog.

Once you get the ISP frequency correct, you can reprogram various fuses for
higher frequency oscillator options.

OK. I am  new to development kits/systems.  I have my STK-500 set up 
with power (beibng stolen from a disk drive power connector in my PC) 
and the serial connection.   When I try to program in the switches and 
LED sample program, it fails, and the tip suggests checking clock 
frequency setting.  WHERE am I supposed to check that, and where do I 
set it?
