Bob, Being that I'm one of those 2,000plus readers I've paid attention to this and previous mentions of the newer/more-enhanced PIC16F628. I'm a believer in the addages "If the spoke is broke fix it" and "if it's not broken, don't fix it". This saying meaning sometimes it's better to replace the entire wheel than to fix the spoke, but if it's not broken in the first place.... Anyways, I've been gearing up for quite some time on a project that will use a digital frequency readout. I've seen alot of existing plans/code for frequency counters with displays that use pre-scalers. One, in particular uses a $3 digikey prescaler chip (cant remember the chip right now) and is claimed to work up to 2.4ghz. I would not need to go anywhere near that high as a counter for this project. With this in mind, I wonder what code exists as "freeware" to use as a counter with the newer PIC16F628 or if the older F84 code will work on these newer chips? I'm guessing the code won't because of the differences in the clock speed. My display will consist of 4 digit LiteOn LED's that were origionally intended for clock diplays as there is a colon in the middle of the display. It can easily be used as a simple 4digit LED just the same. Reason for these LED's is that I've got over 650 of them to use up. I'd rather not have to write code for this project at my present level of PIC expertise. 73, Mike Kendall ke6cvh@the-i.net ----- Original Message ----- From: "Bob Ammerman" To: Sent: Thursday, August 09, 2001 6:01 PM Subject: Re: [PIC]: Building a Servo > Herbert, > > You are certainly welcome to use the F84 for your project (and it should > work just fine).
