The following list indicates what microcontrollers are compatible with this demo.
The following table gives a rundown of the USB utilization of this demo.
USB Mode: | Device |
USB Class: | Communications Device Class (CDC) |
USB Subclass: | Abstract Control Model (ACM) |
Relevant Standards: | USBIF CDC Class Standard |
Usable Speeds: | Full Speed Mode |
This bootloader enumerates to the host as a CDC Class device (virtual serial port), allowing for AVR109 protocol compatible programming software to load firmware onto the AVR.
Out of the box this bootloader builds for the USB1287, and will fit into 4KB of bootloader space. If you wish to enlarge this space and/or change the AVR model, you will need to edit the BOOT_START and MCU values in the accompanying makefile.
This bootloader is compatible with the open source application AVRDUDE, or Atmel's AVRPROG.
After running this bootloader for the first time on a new computer, you will need to supply the .INF file located in this bootloader project's directory as the device's driver when running under Windows. This will enable Windows to use its inbuilt CDC drivers, negating the need for custom drivers for the device. Other Operating Systems should automatically use their own inbuilt CDC-ACM drivers.
The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
