IN AM3517 datasheet ,the UART3 CIR Features is describled as below:
The CIR (UART3 only) includes the following key features to provide CIR support for remote control
applications:
• Transmit mode only (receive mode is not supported)
• Free data format (supports any remote-control private standards)
• Selectable bit rate
• Configurable carrier frequency
• 1/2, 5/12, 1/3, or 1/4 carrier duty cycle
thebig problem is : CIR don't support receive mode,
it is a very strange feture.
In most remote control applications,what we need is to receive signal from IR device,
so WHY? and how to solve it?
thanks.
