Working with multiple STEVAL-EVK-U0I boards

[oaa3wf]

Hi, 

I'm curious to see if it is possible to connect more than one STEVAL-EVK-U0I boards to a computer and read images of all of them? The SDK has  an init function that allows you give a board id, but it is unclear what the board id means or if it will give the desired effect. Any help is appreciated. 

Thanks

Hi @oaa3wf ,

It is indeed possible to use simultaneously more than one STEVAL-EVK-U0I boards. An id (starting from 0) is automatically attributed when more than one board is detected. You just have to define two sensor_dll object in the python script:

# # Init the board
first_sensor_dll = SensorDll(LIB_NAME, decode_frame)
first_sensor_dll.init_board(board_id=0)
second_sensor_dll = SensorDll(LIB_NAME, decode_frame)
second_sensor_dll.init_board(board_id=1)

 Best regards,

Jean

Thanks @Jean_Poire . I'll give it a try.

So I gave this a try and got the following:

Loading st_brightsense_sdk_vdx6gx.dll
IMG platform version 305 loaded :)
Boards connected: (0,P4405C-00A#0306) (1,P4405C-00A#0310)
Board ID selected : 0
Initiating CCI communication at address 32
Sensor detected on interface 0

Boards connected: (0,P4405C-00A#0306) (1,P4405C-00A#0310)
Board ID selected : 1

IMG_PLAT error (1): Error: Wait8, could not reach value 0 for register 513 last read: 1;(Failed to acknowledge command)

Still debugging, but going to but it up here in case someone has run into this before.
