Normally, the * reprogramming of an AVR device must be performed using a special piece of programming hardware, through one of the * supported AVR programming protocols - ISP, HVSP, HVPP, JTAG or dW. This can be done through a custom programmer, * a third party programmer, or an official Atmel AVR tool - for more information, see the Atmel.com website. * * Alternatively, you can use the bootloader. From the Atmel factory, each USB AVR comes preloaded with the Atmel * DFU (Device Firmware Update) class bootloader, a small piece of AVR firmware which allows the remainder of the * AVR to be programmed through a non-standard interface such as the serial USART port, SPI, or (in this case) USB. * Bootloaders have the advantage of not requiring any special hardware for programming, and cannot usually be erased * or broken without an external programming device. They have disadvantages however; they cannot change the fuses of * the AVR (special configuration settings that control the operation of the chip itself) and a small portion of the * AVR's FLASH program memory must be reserved to contain the bootloader firmware, and thus cannot be used by the * loaded application. Atmel's DFU bootloader is either 4KB (for the smaller USB AVRs) or 8KB (for the larger USB AVRs). * * If you wish to use the DFU bootloader to program in your application, refer to your DFU programmer's documentation. * Atmel provides a free utility called FLIP which is USB AVR compatible, and an open source (Linux compatible) * alternative exists called "dfu-programmer". */Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
