Currently, I am trying to get some data from WSN via SPI by running ADVisionSensorController,

 
but I can not access it.

 
After issuing Enable VOS from GUI,

 
via SPI,

 
First command) Issue 0x00000001

 
Next command) Issue 0x00000005

 
Next command) Issue 0x00000003

 
 

 
I am waiting for that response from BLIP2, but I can only read 0xFFFFFFFF.

 
 

 
Could you let me know what kind of setting is correct?

 
Below is the current setting.

 
SPI Master is an Arduino Uno.

 
SPI Configuration is LSB FIRST.

 
CLOCL_DIV is 4.

 
  

 
Firmware is using VOS_Outdoors_realtime_BLIP2.dxe.

 
And it is also GUI, In GeneralConfiguration.xml,

 
DebugMode : true

 
UnifiedGUI : true

 
BlobCoordinatesViaUSB : false

 
Thank you for your help as always.

 
Best regards,

 
Sofy

    Hi Sofy,
    
 
    Is the TRIGGER_WSN from the VOS Target handled by the Arduino UNO.
    
 
    Please have a look at the Figure 1.3.2 which is available in SPI_Communication_Protocol.pdf.
    
 
    So the correct sequence is - Send_BlobInfo_CMD
    
 
    Wait until Interrupt is received
    
 
    Then Send_Data_CMD
    
 
    Thank You & Regards,
    
 
    Sudheer

    Hello, Sudheer,
    
 
    Thank you very much for your response.
    
 
    The customer is following SPI_Communication_Protcol.pdf 1.3.1.
    
 
    But that interrupt doesn't come from BLIP after sending START_MONITOR via SPI.
    
 
    I will take a look more to the customer situation.
    
 
    and let you know at once.
    
 
    Best regards,
    
 
    Sofy

    Hello, Sudheer,
    
 
    Eventually, WSN_INT signal is toggled.
    
 
    It seems the reason is bus traffic or scheduling between GUI apps communication and SPI communication.
    
 
    Because when toggle "enable/disable VOS button" on GUI apps, asserting WSN_INT signal is happened.
    
 
    Thank you for your help as always.
    
 
    Best regards,
    
 
    Sofy
