Help troubleshoot EE Treasure Hunter

[arjoca mihai]

Hi,


Thanks a lot for help, I make the corrections
In the diagram, now VR1 Has effect on the output tone,
But I’m still in trouble with the code (pi84.asm) I studied
a little the code and the set of instructions for PIC 16f84,
and I’m aware that I have to do some changes I’m not sure yet,
I try to put a oscilloscope onto microcontroller pins, TR4 (the mosfet) gets
a little hot when I connect the search coil.
Best Regards,
Arjoca Mihai
