PIC10F pullups

[bittwidler]

I'm probably missing something basic here, but I can't seem to get the weak pullups enabled on the PIC10F206. I've tried the "port_x_pullups()" function, using everything I can think of for x( starting with b), but the compiler doesn't like it. I was going to do a #byte definition, but the OPTION register doesn't have an address.

Any ideas? Thanks for the help!

The 'option' register, is the register used to configure the watchdog prescaler, and pin change operation. Hence it is accessed through the 'setup_wdt', of 'setup_counters' operation. The pullups _default_ to 'on', if the bit is cleared, so there is only an option to disable them (look in the include file for the processor, and the data sheet). So:

setup_wdt(WDT_18MS);

Will also automatically enable the pull-ups. While:

setup_wdt(WDT_18MS|DISABLE_PULLUPS);

Will turn the pullups off.
Obviously choose your required timing for the watchdog.
