I keep getting this error after compiling that wont download the code. does it on both mega mini and micro board, however computer recognizes the board on comm 4.
Arduino: 1.8.8 (Windows 10), Board: "Arduino Pro or Pro Mini, ATmega328P (5V, 16 MHz)"
Sketch uses 4756 bytes (15%) of program storage space. Maximum is 30720 bytes.
Global variables use 236 bytes (11%) of dynamic memory, leaving 1812 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't set com-state for "\\.\COM4"
An error occurred while uploading the sketch
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
Try restarting your computer. Sometimes the COM ports will get stuck in an unusable state and the restart will fix that.
That did not help, still getting the same error message.
