Does anyone know how I can publish images and files?

Thank you very much Qiaozhi.

Hi ionut_mtb, the video has helped me.
I want to make you a query; When I load the hex file and press the read button, the fuses appear automatically but they are incorrect according to what the creator proposes.
My question is: should I change it manually?
Here I leave you an image.

Thank you very much ionut_mtb.
I would like to know what the last hex file is for; Paloma gave me two files and I don't know what the difference is between the two.

I use v3.35, the last one, you ca find it here on the forum. To find answers to all your questions you can use “search thread” on top of the page. More clear info you can find diectly on felezjoo website on iranian forum, use google translate.

Ηι, who is the right way to calculate the damping resistor for coil ?
i find this : Rd= pi*L*circuit resonance

Here are another way - you can connect ten resistors all by 50 Ohm in series and chouse optimal resistance with 50 Ohm step manualy.

thanks, but how i know when to stop i dont have any special eguipment

In this circuit if you follow the exact schematic, pcb, value of conponents and coil construction you don’t need to modify dumping resistor

thanks, are you say that dont need resistor in coil is ready in pcb

[ionut_mtb]

Yes, RDump already on pcb

do you think it is possible to increase the working frequency beyond 999hz, perhaps using a frequency multiplier?
