felezjoo PI(the best pulse induction metal detector that I made until now)

[jladre]

Hello again. My PI md works, after setting correct fuse bits .It works well with all my coils of previous projects. But there is a new problem, count of starts is not reset after reprogramming atmega 328p .It is against the following-At the end of 300 times,with a programming can be re-used again and again to set up the system. Doesthissoftware solution ?

Set resetvfuse bits. I forgot the reset fuse.

You missed to read all the posts from the beginning, i explained that earlier.
Variables which are set and further changed by working code are stored in internal Atmega's eeprom (1kb).
So, to overcome that problem; you must erase eeprom content.
Simple reprogramming Atmega with hex code will not overcome the problem.
Erase internal eeprom.

OK.Thank you. With AVR Studio 4 was able to do everything. Programmer MKII. What size of the coil is recommended? I have several 20 cm , working well for now.1.6 om - 330 mkh

any size will do!

can I get the ".sch" and ".brd" files for the project please?

by the way how sensitive is this detector? I read somewhere that Pulse Induction detectors are not too sensity, and good only for big items.

Low Fuse: F7 High Fuse: D9 Extended Fuse:FC

Ask me anything about AVR top secrets... and i'll be glad not to answer you!

After transfering all parts to my new easy open waterproof box my lcd seems damage. Can anyone tell what would be the problem? I had already check the wirings and it is good and correct. Lcd display photo is below.

Either is broken either you swapped wires.
Also check paths from Atmega to LCD.
Check all over again.

Most probably it detached from its base. There are rubber-like contact ribbons that provide contact between a LCD base and a LCD glass, and those are notoriously flimsy. That's one of the reasons I hate LCDs for terrain use. You may try to fix it, but your better choice is to simply replace a whole LCD and avoid hours of frustration.

Ive check everything and i really suspect that lcd is the problem.. I going to replace a new one.

Now i have to run my machine without lcd.https://m.youtube.com/watch?v=gG0qjZm0m58
