PIC18F45K80 runs way to fast.

[bmoe79]

Hi.

Im using the PIC18F45K80 for the very first time and use a 64MHz external clock source.
To test the new hardware, and to see that it's alive, I just blinks en LED.
The example blinks the LED way to fast, I just can se a flicker, but if I increse the pause to 5000, then it blinks 36 times in one minute.
Anyone got an idea why this happens?


while 1
high portd.7
pause 500
low portd.7
pause 500
wend



Here is my complete code:

I haven't looked at your CONFIGs and I've never run a PIC with a direct clock signal but the first thing that pops is

define osc 64
defines are case sensitive, osc and OSC are not the same.
It absolutely MUST be define OSC 64.

Thank you very much, now it works.

[HenrikOlsson]

Great, and remember that it applies to the other defines you've got in there as well.
