Hi all,
Can any one help explain how to set CGAMMAWD GWDI?
I have a 10-bit sensor link from LSB CIN0(B17) to MSB YIN1(D14). (RAW0~RAW9)
in order to make sure the raw is correct, I do the following test.
step 1. control sensor to OVER EXPOSURE via i2c, then the sensor output will always be 1023.
step 2. set CGAMMAWD[4-1] as 4
step 3. save raw data in VIDEO_captureTskRunIsifIn() API
step 4. open raw data to check the value is 1023.
step 5. repeat step 2 ~ step 4 from 4 to 6
Finally, I need to set CGAMMAWD[4-1] as 4, thus i can get raw value is 1023
(if set as 5 ->raw is 2046, 6->4092)
However, described in the dm36x_vpfe_nda_sprugu5b.pdf, CGAMMAWD[4-1] 4 looks like input sensor is 11 bit ?
(My device list: OV2710(10-bits OV sensor), DM368 IPNC_v5.0)
