	I was merrily compiling along when, out of the blue my code stopped uploading. I changed USP ports several times, I tested with a different board. I tried a completely different program. I rebooted my computer. Same failure persists. If it isn't the board or my code, what could it be and how do I fix it? The build output is attached.

	This is the command to upload. Your can try it from a .bat file or cmd prompt Code D:\Arduino\hardware\tools\avr\bin\avrdude "-CD:\Arduino\hardware\tools\avr/etc/avrdude.conf" -v -patmega2560 -cwiring "-PCOM28" -b115200 -D anoBot.ino.hex:i" Check windows device manager to see which usb driver is installed.

	Thanks, but when I run that command, here's what I get: Code C:\Users\rhjon>D:\Arduino\hardware\tools\avr\bin\avrdude "-CD:\Arduino\hardware\tools\avr/etc/avrdude.conf" -v -patmega2560 -cwiring "-PCOM28" -b115200 -D anoBot.ino.hex:i" avrdude: Version 6.3-20171130 Copyright (c) 2000-2005 Brian Dean, http://www.bdmicro.com/ Copyright (c) 2007-2014 Joerg Wunsch System wide configuration file is "D:\Arduino\hardware\tools\avr/etc/avrdude.conf" Using Port : COM28 Using Programmer : wiring Overriding Baud Rate : 115200 avrdude: ser_open(): can't open device "\\.\COM28": Access is denied. avrdude: ser_drain(): read error: The handle is invalid. avrdude: ser_send(): write error: sorry no info avail avrdude: stk500_send(): failed to send command to serial port avrdude: ser_recv(): read error: The handle is invalid. avrdude: stk500v2_ReceiveMessage(): timeout avrdude: ser_send(): write error: sorry no info avail avrdude: stk500_send(): failed to send command to serial port avrdude: ser_recv(): read error: The handle is invalid. avrdude: stk500v2_ReceiveMessage(): timeout avrdude: ser_send(): write error: sorry no info avail avrdude: stk500_send(): failed to send command to serial port avrdude: ser_recv(): read error: The handle is invalid. avrdude: stk500v2_ReceiveMessage(): timeout avrdude: ser_send(): write error: sorry no info avail avrdude: stk500_send(): failed to send command to serial port avrdude: ser_recv(): read error: The handle is invalid. avrdude: stk500v2_ReceiveMessage(): timeout avrdude: ser_send(): write error: sorry no info avail avrdude: stk500_send(): failed to send command to serial port avrdude: ser_recv(): read error: The handle is invalid. avrdude: stk500v2_ReceiveMessage(): timeout avrdude: ser_send(): write error: sorry no info avail avrdude: stk500_send(): failed to send command to serial port avrdude: ser_recv(): read error: The handle is invalid. avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_getsync(): timeout communicating with programmer avrdude done. Thank you. C:\Users\rhjon> I checked Device Manager output and it lists Arduino Mega (COM28) and says "This device is working properly"

	You are outside of Visual Micro when you run the command so can find help in more technical places for your toolchain. The access denied error you are getting normally suggests the port is open in a serial monitor. You should also check windows task manager to ensure the avrdude.exe process is not locked and hogging the port. It you see an avrdude process you should terminate it.
