How to control exposure time of KAI-29050 using GPO1 in AD9928

Question asked by alex_chen on May 22, 2018

hi everyone,We want to use GPO1 to control exposure time of kai-29050.

GPO1 can control SUB pin of kai-29050.

Sub pulse can be detected with an oscilloscope.

When we changed the GPO1 signal pulse position, the output image gray level did not change.

Here're some of our's register values (related to GPO1)

(0x07A,0x0FFFFDE),      

(0x071,0x0004000),      

(0x07C,0x000A001),      

(0x07D,0x0002000),      

(0x07E,0x0000007),      

(0x07F,0x000A002),      

(0x080,0x0004000),      

(0x081,0x0000008),      

(0x073,0x0000006),      

(0x070,0x0000010),      

Do we need any Settings for our AD9928 register?

Thanks!
