The SDK library implements the functionality required to build an application which controls and collects data from an AdHawk Eye Tracker.
There are sample board support packages (bsp) for Zephyr / ESP32 / FreeRTOS / Linux. These can be modified as needed. If your board is different they can be used as reference implementations.
To get up and running quickly refer to the examples folder. These implement a basic application as well as the required build infrastructure.
AdHawk's Wireless Mindlink hardware is useful for quickly testing and bringing up an eye tracking application. It can be easily connected to a devboard or hardware of your choice.
To connect the AdHawk eye tracking hardware to your devboard:
- Connect the SPI breakout board to the AdHawk board using the provided ribbon cable
- Connect the GND, CLK, MISO, MOSI, CS (SS) pins of the SPI breakout board to your devboard
- Connect the USB / Battery OR connect the PWR pin to power the AdHawk eye tracking hardware
There are two firmwares for the AdHawk's Wireless Mindlink hardware:
- The first (kakapo_v4) implements our wireless / usb product and can be used to test and configure the eye tracker
- The second (kakapo_v4_sdk) is for SDK development. This firmware simply powers the eye tracker and disables everything else
Currently an nRF programmer is required to switch between the two different firmwares.
