As we know DLPC3436 supports 3D by input to FGPA the pin "FPGA IN_3DR" as mentioned in http://www.ti.com.cn/cn/lit/ds/symlink/dlpc3436.pdf page 25.
The questions is how the AP (Android system) could output this signal to the FPGA, in terms of software and hardware?
In hardware, I believe we have to connect a GPIO to FPGA from the AP.
In software, will an 3D player in Android be able to drive this GPIO?
The question might be a bit out of scope for DLPC3436, but it is related, and may help others who need to understand how 3D works. I believe TI expert understand the full picture, and would be much appreciated if it could be helped.
