Hi,

I do some very simple stuff with the 8 pin pics - the 508a, specificaly. I got tired of having to UV erase chips and picked up some 675's.

After trying to program one, it performed erractically and I realized there were some things I missed. I've looked at back messages on the PicList and have managed to get myself hopelessly confused regarding osscal values, how to use the internal clock, etc.

So....

Could someone do a quick handholding walkthrough with me?

I've got a brand new, virgin 675 on my desk. I want to use the internal clock. All I want to do is blink LEDs on GPIO.0 and GPIO.1

I do not want to use the AC/DC comparators.

What Defines do I need at the beginning?

Do I need to read a value for OSSCAL, write it down, and re-enter that each time for each individual chip like I had to do on the UV eraseable ones? Or is there an easier way?

I know this is pretty basic, but I have managed to get myself throughly confused.

Thanks,

Mike Tennent


PS - I'm using PicBasic Pro
