Pinpointer with discrimination "Cat-FM" on ATMega328P

[void118]

thanks void118, the full firmware gladly accept it!
I am waiting for the new pcb to arrive, so at the moment I have no way to try it, but if you send it to me as soon as I'm ready I use it

Hi, just Install "USB Network gate" demo version to your PC https://www.eltima.com/products/usb-over-ethernet/ and let me know when you will be ready to upload full firmware please.
Full firmware will be uploaded remotely.

[void118]

are there any performance changes compared to the old firmware?

I hope now It's more stable and user friendly and I added some math to the main algorithm, assembler + math Is very powerfull tool!

Now I think about new pinpointer schematic, It will be very simple, sensitive and without any MCU, but I don't have enougth time to do this project, moreover I must create SMT layout for "Cat-FM" v2.0

I have dubious functions in remote programming, I use atmega328p barebones and as a programmer an arduino uno. Anyway we try

Look at this please, https://aliexpress.ru/item/33009024856.html only 2 Euro and all your troubles will be far away)

or https://aliexpress.ru/item/32686480247.html any color on your choice)

Great!

And may be I'll add on/off function to set button...

Dear void118,
I'm having trouble getting the 16MHz crystal. Can I use a 20 MHz crystal? Is it possible to change the source code to operate on this frequency?
Best regards!

Can you explain to me why you want to upload the firmware remotely?

Hi, It's not good Idea because In this case you must Increase your generator frequency to 25-30 kHz and this will lead to Increasing sensitivity to earth's magnetic field and we will see false alarms e.t.c
I can change my source code special for you but I'm sure order crystal from aliexpress will be much cheaper

Yes of course, until firmware on my PC It's In my area of responsibility and If I'll send few copies to my friends I'm sure that tomorrow mornig It will be shared on the Internet.
And It's not about mistrust, I don't want to offend anyone, I'm Just being Insured.
It's not a big problem to repeat "Cat-FM" design with yourown code, but I spent a lot of time and I don't want to share It for free.I published free 1.6.2 version and I think It's enougth for benefit.

I understand that it is a security issue, I am writing to you in private to explain something

If I use a 10MHz crystal. Will it have a frequency between 15- 20kHz?

For Brazil, AliExpress products arrive 2 months later!
Thank you!

Ouh), don't worry, my orders from aliexpress to Russia arrives within two month too). Now look, generator frequency dosn't depend on crystall frequency, 16MHz Is the base frequency for whole system (calculations, sound e.t.c) so If you will try to use 10MHz one I have no Idea what Is will be wrong. I can give you magic link to worlwide complonents store, you will receive your order within one week) https://lcsc.com
