I made it and works perfectly. Title: Re: 50 MHz frequency counter Post by: bbarney on March 30, 2008, 01:52:36 13:52 I didn't find a hex file for the exlusive frequency counter that uses 2x16 line LCD,any chance you have it?
Title: Re: 50 MHz frequency counter Post by: pl4tonas on March 30, 2008, 05:52:01 17:52 I bought it as a kit.
I will try to read the PIC, if it is not copy protected I will upload the hex. Title: Re: 50 MHz frequency counter Post by: bbarney on March 30, 2008, 06:35:05 18:35 I'am keeping my fingers crossed ;D ;D

I already tried it and built it, and damn, it works... http://www.geocities.com/alibhernlem/Radio/freq.html You can find the source file on the PAGE Title: Re: 50 MHz frequency counter Post by: bxngoc on May 02, 2008, 07:51:16 07:51 How about 100Mhz one?

I'm not find a hex file for the exlusive frequency counter, please re upload. Title: Re: 50 MHz frequency counter Post by: fythsg on May 09, 2008, 05:36:19 17:36 what precision on it?

Checking the links listed i found this project. http://www.marc.org.au/marc_proj_lcmeter.html Using a PIC16F628 with a few parts and with hex files and code. I am interested in assembly it. Anyone did it? It´s work fine?

Hi, this is offtopic a little here, but look at this link: http://ironbark.bendigo.latrobe.edu.au/~rice/lc/index2.html Here you can download also the asm source for the LC meter (lc2.txt). This is an interesting project... No, I don't tried it yet, but I want (will) prepare a Proteus simulation to try it, and I'll upload it. zuisti Title: Re: 50 MHz frequency counter Post by: LinkSys on May 26, 2008, 01:02:19 01:02 Hi, Hi,this is offtopic a little here, but look at this link: http://ironbark.bendigo.latrobe.edu.au/~rice/lc/index2.html Here you can download also the asm source for the LC meter (lc2.txt).
