Forum Post: vsp01m01 capture and strobe signal parameter –frame number

hi,I use vsp01m01 for image capture,and get some problems:

Set reg  0x36[5:3]=0x7---frame trig

Set reg  0x36[2:0]=0x0----frame now

Step1: Set reg  0x21[5:0]=6’b011110

Set  0x22[5:0]=6’b000101

Set  0x20[5:0]=6’b000011

Step2:set  TRIG signal high

Step3:set  TRIG signal low

Step4: Set reg  0x21[5:0]=6’b000000

Set  0x22[5:0]=6’b000001

Set  0x20[5:0]=6’b000010

Q1: Capture a picture,my step is OK ?

Q2: About  frame number ,The red number is OK ?

Q3: Why I set strobe parameter frame number =7,the strobe signal is not synchronize with frame 2?It always synchronize with other frame ?

Expact you answer,Thank you.
