No speed change between EC_IO and H4
PostPosted: Wed Aug 23, 2006 9:14 pm     Reply with quote
Hello,
In the code below I'm toggling pin D2 and measuring with a scope.
When I swap EC_IO for H4 I don't see a speed difference on D2.
It should be 4x quicker no? The config bits are changing in Mplab.

Thanks, Pete

10mhz TTL osc to osc1
Using ICD2 and Mplab

Code:


#include <18F452.h>
#fuses H4,NOWDT,NOPROTECT,NOLVP,PUT

void main(){

for(;;){
          output_high(pin_d2);
          output_low(pin_d2);
         }

}

Thanks for the quick help. I can go to bed now Smile
