ho acquistato una Mega per superare le ristrettezze della Uno in flash e Ram, ma pensavo si collegasse alla usb come la Uno.
Davvero devo usare una Uno per caricare la Mega ?
Non c'è un diverso driver da scaricare ?
I thought to simple connect the usb to the new board (the previous was Uno.3) and load the program, but no COM with the Mega.
Really I have to use an Arduino Uno as an AVR ISP ?
The "Arduino MEGA" uses an FTDI chip for USB-to-Serial. You need to install the FTDI drivers.
Here is the website I used to install the FTDI Drivers. It works for me.
I used it with the Mega and Nano.
the new hardware doesn't find any driver in the unzipped folder (jpg).
Perhaps you should try the "setup executable" instead:
