Because...even without setting config registers (I suppose depending on the programmer and any previous settings that might be 'locked in'), the '4550 will start up (as most newer PICs will) with a 1Mhz internal clock (depending on the PIC model), not perfect, but enough to get things up and running... especially the ol' "blinky led" type program.Originally Posted by mister_e
What the heck happen on this forum since few weeks/months? Guys, if you can't help, don't answer, don't waste your/our time and bandwidth. Even if this is a simple question, 18F4550 have tons of Configuration fuse to set. Can be enough to stop someone to use it. There's really a lot of a s s kicking to do here
And...You and I both know that the '628 blinky led program wasn't going to work as expected in the earlier post since there is no mention of the ADCON CMCON registers. This is all mentioned in the PBP manual under section 2.5, which is labeled I've Got Troubles, where it specifically mentions the comparator and the analog ports, not to mention the issues with RA4, all of which seem to plague SOOOO many people. But that assumes that the person has a copy of the book.
And as far as the pins being configured as inputs on reset, the HIGH and LOW statement for the 'blinky led' program should take care of that.
