In the actual state of the project, there is a demo application (screen/sterioscopic) that shows two different image on the screen flipping in every vblank event (screen refreshing), one is a big circle and the other a big rectangle with an other small rectangle in the corner. The small rectangle of the corner is a token for a photodiode stick on that corner, this photodiode connected to the ADC pin of the RISC-V microcontroller is acting as a flip image sensor.

The RISC-V microcontroller is cleaning the photodiode signal and sending digital synchronization signal to the FPGA throw the RF Transmitter.

The FPGA is getting the sync signal and opening right or left lens.
