Forum Post: RE: Using TI 2A to control gain only

Hi Rajat,

I am using IPNC RDK 3.5

Our application requires manual exposure control. When this option is picked, I wish that only gain will be automatically controlled by 2A algorithm.

I am familiar with the following file:

Source/ti_tools/iss_03_80_00_00/packages/ti/psp/iss/drivers/alg/2A/src/issdrv_algTIaewb.c

is this the source code you're referring to?

Another option I thought about is setting both of the following parameters:

gTi2aControlParams.minExposure
gTi2aControlParams.maxExposure

to the manually chosen exposure value when manual exposure control is used. I will try implementing this and see if it causes any problems.
