Reset 8u2 on Arduino Mega 2560


Another question along with this one.


The guide I've been following says that after you reset the 8u2 by connecting the two pins shown below, the board should be undetectable by the Arduino IDE. I have successfully done so, but the board is still using COM22 as an Arduino Mega in the device manager. This other guide I found shows the board becoming a LibUSB-Win32 device. Anyone know what's going on?


Pins to connect



Answer



Apparently, my mega did not have the 10k resistor built in for whatever reason. Adding the resistor on let it enter DFU mode without a hitch.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
