IDS peak 2.8.0 / uEye+ firmware 3.33
|
This function is supported by the following models: U3 models •PCB version uEye+ LE USB 3.1 Rev. 1.2 (requires USB3 Vision firmware 3.2 or higher) •uEye+ LE USB 3.1 Rev. 1.2 AF (requires USB3 Vision firmware 3.2 or higher) •USB 3 uEye+ ACP GV models •GigE uEye+ ACP UI models •PCB version uEye LE USB 3.1 Gen 1 •PCB version USB 3 uEye LE •PCB version USB uEye LE •GigE uEye LE |
Returns the I2C mode. The I2C mode determines the speed grade of I2C communication.

Values description
•FastMode: I2C fast mode with 400 kHz clock frequency.
•FastModePlus: I2C Fast-mode plus with 1000 kHz clock frequency (requires Vision firmware 3.20 or higher). This feature is only supported by uEye+ cameras (GV and U3 models).
•StandardMode: I2C standard mode with 100 kHz clock frequency (requires Vision firmware 3.20 or higher). This feature is only supported by uEye+ cameras (GV and U3 models).
|
Note for GigE uEye+ ACP To use the increased transmission rate of the I2C of 1000 kHz (Fast-mode plus - requires Vision firmware 3.20 or higher), you must connect external pull-ups of 3k3 to 6k3 (1.5 mA to 2.0 mA) to both I2C signals. |
