I am having troubles with setting the internal oscillator for the 18f2220 to it's maximum value of 8Mhz. When I run the program, it runs very slowly. I am using flowcode which has a config screen. It has no option for setting the speed.

Is there a certian config word I can use to set this value?


Thanks in advance...
Cameron

OSCCON = 0x72 makes osc start up full speed if not in code it will run at 31khz read page 28 of the data sheet

It also depends on what languish your using to but is not a configuration word

You should added it before you set up your ports

OSCCON = 0x72
TRISA = 0xFF ///don't use this it just here for clarity
