ATTiny84 PWM flickers on pins 4 and 5

GoogleCodeExporter commented 8 years ago

What steps will reproduce the problem?
1. Set pins 4 or 5 to output
2. analogWrite() to the pin (flicker is most noticeable at lower values)
3.

What is the expected output? What do you see instead?
Pins 2 and 3 work perfectly and output a steady light.  A digital write HIGH 
does not flicker on either pin.

What version of the product are you using? On what operating system?
OSX, Arduino 1.0.1.  Using Arduino Uno as ISP

Please provide any additional information below.

Processor speed?

And that is it.  I was using 8MHz board but hadn't burned the 8MHz bootloader.  
Tried it with both 8 MHz and 1MHz speeds after burning the appropriate 
bootloader and it is working perfectly now.  Thanks, and sorry for the trouble.
