GoldPic code Again

[johnandles]

Hello Goldfinder
see Stuarts micro PI...http://www.geotech1.com/cgi-bin/page...art2/index.dat
The circuit and asm. file there also,but for 16c not 16f84a.
Maybe you can port it to a 16f84a?
This detector is very similar to goldpic but has no lcd.
Cheers

I built a GoldPic 3. though the detector works well for beach combing I need to reduce the sample delay from the programmed 30uS to around 10-15uS. Since the code is locked on the chip I bought I can't do it so anyone having a code that would be adjustable would be great. TIA

This is only thinking out loud..maybe there is an adjustable analogue method of delaying the sample pulse that is generated by the PIC, so it falls just behind the next TX pulse?.
Therefore achieving an adjustable sample time.
Any thoughts?
Cheers

I have the Goldpic code somewhere as i built it quite a long time ago ( 6-7 years +) I can't remember where I saved it but anywhay it's a not more than a toy, there are better projects to build.

Hello

I find this Hex code on http://www.detector-planet.com/ for gold pic 3.01 from Trover R. Hill

Thanks. I'll give it a shot!

Hi you all! Goldpic, is as someone said, seems to be a toy! The code can easily written in picbasic! Assembly is not necessary since this is very basic stuff and can be done easily so I suggest to use a "simple" high level language (and not deal with assembly unless you have a lot of free time!) Picbasic pro is more than adequate!
