无线键盘、鼠标、接收器电路和源程序 全套文件设计及代码
CY4672 PRoC LP KBM RDK v1.00
The CD contains a self-extracting installer at the root of the CD:
"Install_CY4672_RDK.exe"
The CD also contains individual copies of all of the files contained in the installer.
It is recommended that the installer is used instead of copying files from the CD.
The installer performs the following functions:
-Installs a copy of the CD files to a specified location on the user s
hard drive.
-Creates a CY4672 RDK Program Group
-Creates shortcuts to the WirelessUSB.exe Software Application
One benefit of the installer is that all of the files are installed with read/write
permission, which is required for some files when attempting to build the
software and firmware projects. Files that are manually copied by the user from
the CD to their hard drive have read-only attributes by default.
