Hardware Features

  1. The data path of Camera and Mic is connected to FPGA and the output stored in SRAM. This is done infinitely from Monocle Bootup till monocle sleeps.

  2. If any Touch event is detected, MCU commands FPGA to freeze the Frame buffer and Audio buffer stored in SRAM and queries the Frame to Transfer through BLE and/or Display the image to OLED.
