Hi all, first time poster here so please forgive any protocol lapses.
I'm using a Tiny AVR Programmer to program a bare ATMega328P. I've been using the following site:
Started using Arduino 2.3.0 but switched to 1.8.19.
From Nick Gammon's site, I successfully uploaded the Board_Detector sketch and Board_ Programmer. I never saw the Serial Monitor window however. When I selected that from the Tools menu, I get the following error:
Error opening serial port 'COM6'. (Port busy).
Note: when I tried this with 2.3.0, I received a similar error:
Timeout: The IDE has not received the 'success' message from the monitor after successfully connecting to it. Could not connect to COM6 serial port.
I selected Board: "Arduino Uno:", Port: "COM6", and Programmer: "USBTinyISP". I have one line of code to send to my MCU but I think I need the Serial Monitor to do it.
Any thoughts?
