Hi,

is it possible to add the definitions for the:

• Attiny 2313a
• Attiny 4313

to the main-programm?

This both devices support HVPP and I would like to use avr-hv2 with this MCU.
The datasheet can be found here:
https://ww1.microchip.com/downloads/en/DeviceDoc/doc8246.pdf

Thank you.

Hello
I programmer a atmega644p and set fuse cksel[3-0]=0001
And my arduino as isp can't detect chip again by avrdude
So can avr-hv2 solve problem or not ?
Thank you 😊 for your help

Thank you for publishing this project, I am close to ordering one of this. I just want to know how to use this, I am new to HVPP and would appreciate a guide similar to this can be created https://www.instructables.com/AVR-HVPP-Configurator/

I have a bricked ATMega32U4 (Arduino Pro Micro), I get this classic error:

avrdude: error: program enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

I am hoping I could fix it with this. I know this would take your time, I willing to pay for this service.

(no, this isn't really an "issue.")

It happens that I have some ATtiny28 chips that I want to program.
These are only programmable via HVPP, and my STK500 doesn't seem to be working, so I looked around for something else that might be able to program it, and found your avr-hv2 project.

I based the hardware (built on a protoboard) on your project, plus the datasheet, plus some other HV programmers, and started with your firmware. I don't think that much of it is left - the ATtiny28 works somewhat differently, I didn't try to make it more general, I used an ATmega4809 board as the programmer, and I implemented a more user-oriented communications protocol, but I wanted to thank you for publishing your project, since it was definitely easier to start working with it than to start from nothing...

Should you need to program a very old HVPP chip, it might be useful to look at. It's here: https://github.com/WestfW/Duino-hacks/tree/master/hvTiny28prog

Thanks!

In Windows OS, is it enough to type for example COM7 or specific path should be entered.
If specific path should be entered, how to get that path?
