it11 Hello,
We only get 8bits data from 12bits mt9p031. Capture high 4 bit data from mt9p031 always is 0, the low 8 bit is okay. but the high 4 bits has data bits through oscillocope. ( This mode is CCDC_NO_COMPRESSION). and data bit11 of mt9p031 is connected to CDATA 11.
CCDCFG = 0.
MODESET = 0
CGAMMAWD = 0x1108
****************************************************************************************************************************************
If we use CCDC_ALAW, but the getting 8 bits data is very small. That is to day, the high 4 bit hasn't data.
How can we get correctly 12 bits data form mt9p031? That is to say, we can get high 4 bit data when use CCDC_NO_COMPRESSION.
When we use CCDC_NO_COMPORESSION, the sdram is set 16 bit pack(not 12 bit pack), is it correct?
waiting for your answers,
The folling is using by CCDC_ALAW, the registers of CCDC.
