The ATmega32U4 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). The 32U4 also allows for serial (CDC) communication over USB and appears as a virtual com port to software on the computer. The chip also acts as a full speed USB device, using standard USB COM drivers. Mar 12, · Do you mean you're using an Atmega32U4 in DFU (Device firmware update) mode? If this is the case you must realise that the chip itself has a usb component but not an internal usb driver. As such, you either have to write one or get a USB library, upload the hex to the device, then use their windows driver to talk to their atmega usb ted Reading Time: 6 mins. May 06, · Hello everyone A friend of mine has made a board with an atmega32u4. It is a simple board, more or less just the chip, a 16mhz crystal with 22pF caps, 10kO resistor for pullup of RST line, USB connector. All pins are connected simply to pinheaders and have no other things attached. I thought that when I plugin the board, it should automatically try to install the driver on my windows XP (32bit.

Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. When this is done, Windows 10 if the proper drivers are installed recognizes the device as ATmega32U4 chip.
But that hardware pretty much just does the electronics, it doesn't control what data is sent or received. And data must be sent and received to identify the device and enumerate. If there is no software on the chip, no data is sent, and the chip will not enumerate at all. Windows will probably report that "one of the USB devices connected to this computer has malfunctioned", but it might not even detect it at all. But the chips usually come from the factory with a DFU bootloader on them though completely blank and differently programmed chips are also available.
So windows loads that driver, and the driver tells windows that it is a ATmega32u4. Presumably, you want to do something else with the chip in the long run. So you'll need to program it with your own application. You can't and wouldn't want to run the bootloader and your application at the same time.
But you can leave them both on the chip, and switch back and forth with some special code, fuse settings, or by pulling a pin to ground during reset. This is great for development, because that bootloader can be used to upload a new copy of your application. It's also handy if you want to let customers do firmware upgrades in the future. But while your application is running, the bootloader is not. Instead, your application will have to do all that.https://alltheurl.com/hdpvrcapture-download-v3/
And it's complicated. But the good news is that there are libraries which do most of it for you. The most common is called LUFA. So, on microcontrollers, you have to write firmware that handles USB, and that includes reacting to packets from the host that ask for things like vendor and product IDs.
So, there's software running on your microcontroller that talks to your PC according to the USB standard. Chances are, that yes, this is bootloader firmware that came pre-flashed by atmel - the reason is simply to allow you to build a device and then program it quickly.
Super handy for production! Whether or not that bootloader resides in user-writable memory and under which circumstances it is run at start depends very much. Your devices data sheet and user guides will have details on that. Sign up to join this community. The best answers are voted up and rise to the top.

Is it software shipped by Atmel which is stored in flash? Because then what would happen when I rewrite the flash memory? Would it then no longer be recognizable by Windows?

How could I re activate the bootloader so that Windows detects the chip again and thus I could again flash another program to it? If that's ticked, the bootloader gets erased, if not then it doesn't. If you program with the bootloader, it won't delete itself.https://alltheurl.com/casio-cw-100-2/
See atmel. The bootloader is in a protected set of pages and you have to use an ICSP to clear the protection fuses. The DFU documentation is updated, see here: atmel.
