The 2021 version introduced a layered driver model:
Application (User) → GenICam API → Sky32VI_Driver.dll (User-mode)
→ Sky32VI_KMD.sys (Kernel-mode, WDM) → PCIe/CXP Controller → Sensor
Key improvements in 2021:
| Issue | Description |
|-------|-------------|
| No public datasheet | Must reverse engineer registers or use sniffed I2C/SPI traces. |
| Broken vendor driver | Only works on old kernel (e.g., 4.x) and fails on 5.x/6.x. |
| Custom UVC or non-standard USB | Requires modifying uvcvideo or writing a libusb backend. |
| FPGA-based | Driver must load bitstream, configure AXI bridges, handle interrupts. |
| Power sequencing | Deep driver needed to bring up multiple voltage rails and clocks. | sky 32 vi driver 2021
It is worth noting a slight alternative to the above. A device named Sky Share was marketed by Globalwin. The 2021 version introduced a layered driver model:
