external clock input to RC0/T1CKI on pic18f252 troubles

[HenrikOlsson]

Hi,
This forum isn't really about discussing issues with compilers/languages other than PBP but a quick glance at your code shows

T0CON = 0x87;
// configure Timer 0 - select 16-bit mode,
// internal clock source, enable 1:256 prescaler

The value of 0x87 seems to correspond with the comment which probably isn't what you want to do if using an external clock source connected to T0CKI.

oh is it i didn't know the forum wasn't a generic one.

oh thats fine its timer1 that is configured for ext clk. timer 0 still needs internal to give my 1 second delay. thanks for the reply though!

Argh, I read the thread title several times and STILL T0CKI.... Must have made a mixup with RC0....
Sorry about the confusion, good luck!
