Readme.txt |
This is the Readme file for hid-mouse, an example of a USB mouse device. In order to have as little dependencies on hardware and architecture as possible, mouse movements are computed internally so that the mouse pointer moves in a circle. WHAT IS DEMONSTRATED? ===================== This example demonstrates how HID class devices are implemented. The example is kept as simple as possible, except the report descriptor which is taken from a real-world mouse. It does NOT include a host side driver because all modern operating systems include one. It does NOT implement USBRQ_HID_SET_REPORT and report-IDs. See the "hid-data" example for this topic. It does NOT implement any special features such as suspend mode etc. PREREQUISITES ============= Target hardware: You need an AVR based circuit based on one of the examples (see the "circuits" directory at the top level of this package), e.g. the metaboard (http://www.obdev.at/goto.php?t=metaboard). AVR development environment: You need the gcc tool chain for the AVR, see the Prerequisites section in the top level Readme file for how to obtain it. BUILDING THE FIRMWARE ===================== Change to the "firmware" directory and modify Makefile according to your architecture (CPU clock, target device, fuse values) and ISP programmer. Then edit usbconfig.h according to your pin assignments for D+ and D-. The default settings are for the metaboard hardware. Type "make hex" to build main.hex, then "make flash" to upload the firmware to the device. Don't forget to run "make fuse" once to program the fuses. If you use a prototyping board with boot loader, follow the instructions of the boot loader instead. Please note that the first "make hex" copies the driver from the top level into the firmware directory. If you use a different build system than our Makefile, you must copy the driver by hand. ---------------------------------------------------------------------------- (c) 2008 by OBJECTIVE DEVELOPMENT Software GmbH. http://www.obdev.at/
