Programming ATtiny85 using UNO R3 (By Ashish Choudary Dec 2020)

Submitted by David on Sat, 11/05/2022 - 22:39

First may I thank Ashish Choudary for a very good, clear, set of instructions for programming the ATtiny85. I have followed them, the ArduinoISP loaded without any errors, the ATtiny85 Support was installed. However when it came to upload the "Blink" sketch (having made sure that the ATtiny85 board was selected) the upload failed with the mesages:-

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x03
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0xe0
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00
Problem uploading to board.  See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

I have looked at the suggested web site and have performed a loop-back test, passed; have checked that the correct board was selected (ATtiny85) and COM 3 (Arduino UNO) were correct. I have also checked that the UNO runs the Blink sketch without ant problems.

As a novice in these matters I don't know what else to do - o help please!

 

Thanks in advance
