ArduinoISP Serial Not Declared

iamhunterstone · April 16, 2021, 2:47am

Hello everyone, I just got a ATtiny85 and I'm trying to program it but I'm not even able to upload the ArduinoISP. I'm following the steps on https://create.arduino.cc/projecthub/arjun/programming-attiny85-with-arduino-uno-afb829 but have been getting an error with one of the first steps. This is what pops up when I try to upload the ArduinoISP from the examples.

Arduino: 1.8.13 (Windows Store 1.8.42.0) (Windows 10), Board: "ATtiny25/45/85, ATtiny85, External 8 MHz"

Would anyone have any reason why i'm having this issue? Like does this work well in the App Version? There's more to the code then what was posted but there's a limit to characters.

Hi @iamhunterstone. I can see your problem here:

You should be uploading the ArduinoISP sketch to the Uno you will be using as the "Arduino as ISP" programmer, but you have selected the "ATtiny25/45/85" board from the Arduino IDE's Tools > Board menu. You need to have Tools > Board > Arduino AVR Boards > Arduino Uno selected when you are compiling and uploading sketches to the Uno.

It's only once you have the "Arduino as ISP" programmer all prepared and are only using it as a programmer that you will switch the board selection to the ATtiny85.

iamhunterstone · April 16, 2021, 9:45am

Oh man thank you very much. Switch that back to Arduino and it worked right away.

pert · April 16, 2021, 12:58pm

You're welcome. I'm glad to hear it's working now. Enjoy!
