WindowsError(5, 'Access Denied.') - dampire - 05-24-2023
HI,
I can't run any code from arduino.
I run the ide with arduine on windows 10.
I installed the drivers that I read in a post for the usb port.
The error:
esptool.py v3.0-dev
Serial port COM3
Traceback (most recent call last):
File "esptool.py", line 3682, in <module>
