use Nodemcu to program Attiny85 I have a dev board for my attiny85.
when connecting it to the computer I get &quot;unknown USB device(device descriptor request failed)&quot;
although I have the needed drivers, so I thought of trying using my nodemcu.
Tried connecting the SPI (to the nodemcu hmiso;hmosi;hcslk;hcs)and upload using &quot;arduino as ISP&quot; and compitable settings(https://www.hackster.io/arjun/programming-attiny85-with-arduino-uno-afb829).
pressing &quot;burn bootloadre&quot; using this way gives me errors:
&quot;avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x03
......
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x03
Error while burning bootloader.&quot;
***EDIT:
After changing a line(#define USE_OLD_STYLE_WIRING) in ArduinoISP (from example)
the error code changed a bit and it shows up much faster:
&quot;Arduino: 1.8.13 (Windows Store 1.8.42.0) (Windows 10), Board: &quot;ATtiny25/45/85, ATtiny85, Internal 8 MHz&quot;

Any help on how to use nodemcu to program attiny85 will be great
thanks
Modifications to the ArduinoISP.ino sketch
I made the following changes to the ArduinoISP.ino file it exists in IDE version 1.8.13, and uploaded it to the NodeMCU board.
In short, I commented out (by way of #if 0) the heartbeat, err, etc LED related stuff.  Not doing this causes the board to reset for reasons that would probably be apparent if I researched it, but I haven't and since I don't plan on using the LEDs and that you may not, I figured I would get this to you sooner.
I changed RESET to be SS which on NodeMCU is D8.
Why LED related code causes resets
... Out of curiosity I just went and looked at the ESP-12F and ESP8266EX datasheets.  GPIO7, GPIO8, GPIO9 all go to the ESP-12F's SPI flash (program storage), so ostensibly monkeying with them interferes with the modules ability to keep executing from the SPI flash.  They're not routed to NodeMCU pins, probably for that reason.  So there's the answer to that.

NodeMCU to ATTiny85 ISP Wiring
The board is wired to the ATTiny85 as follows:
NODEMCU 3.3V -&gt; ATTINY85 PIN 8
NODEMCU GND  -&gt; ATTINY85 PIN 4
NODEMCU D5   -&gt; ATTINY85 PIN 7
NODEMCU D6   -&gt; ATTINY85 PIN 6
NODEMCU D7   -&gt; ATTINY85 PIN 5
NODEMCU D8   -&gt; ATTINY85 PIN 1

On the NodeMCU you'll find all 6 of these together on the right.

avrdude: Device signature = 0x1e930b (probably t85)

avrdude: safemode: Fuses OK (E:FF, H:DF, L:71)

avrdude done.  Thank you.

I've been playing with this chip, so don't be surprised that I don't have the same fuse values you have.
