- LW-H2F register controlled R-G-B gain.
- Simple CMOS debayer
- Loop-back to HDMI via FPGA2SDRAM
- I2C control and adjust via HPS2FPGA fabric.
- Reset\Power control pin via HPS to FPGA fabric IO.
- ToDo VCM auto focus control via IIC.
To control the VCM, user must power on via reg 0x00.
Then setup the below registers settings.
For 10-bit DAC registers are 0x02, 0x03.
DAC 10bit <- Near focus higher value, far focus low value.
$ sudo i2cget -y 3 0x0c 0x01
0x0c
$ sudo i2cget -y 3 0x0c 0x02
0x01
$ sudo i2cget -y 3 0x0c 0x03
0x90
$ sudo i2cget -y 3 0x0c 0x04
0x33
$ sudo i2cget -y 3 0x0c 0x05
0x60
$ sudo i2cget -y 3 0x0c 0x10
0x00
- Very simple no V4L2 driver is used and no Linux control layer is supported.
- No frame buffering, current design can easily use more SDRAM space to hold CMOS capture frame.
