CC2511 Dongle
6.3 Wireless WinAmp remote control
This application example is a wireless remote control for WinAmp media player. It is a two-
way remote, which display the song information of the song played on the LCD screen on the
SmartRF04EB.
The communication between the CC2511 Dongle and WinAmp is handled by a custom
WinAmp plug-in. Hence this remote control will work with WinAmp only.
This application example uses the USB framework found in the CC2511 firmware library to
setup the USB on the CC2511 Dongle and to handle all USB standard requests. In addition it
demonstrates the use of Vendor requests in the USB framework. On the PC the CUDAL
library is used to create a custom driver (see chapter 7.2 Windows USB driver framework).
The radio communication between CC2510EM and CC2511 Dongle is done using the RF part
of the CC2511 firmware library.
The application example also uses the buffer module in the library to handle data buffering
and the timer4 manager module for timing.
