SRF08 interfacing, how to send raw data via VISA (serial)

[Daan_v]

Hello,

I want to interface a SRF08 ultrasonic range finder via serial communication (VISA in LabView). The problem is that I can only send strings to the USB-I2C controller with VISA and I want to send raw data with VISA, because the USB-I2C controller only works with raw data (0x00 to 0xFF).

Who can help me with my problem?

You have several solutions. You can create a U8 array and convert this to string. See the string functions palette. You can also change the display mode of the string. Experiment with  '\' Codes display and Hex display. You find the setting by right clicking on the item. This is valid for both string constant and the control/indicator. Just a warring. I have wasted several hours of debugging. Because I did not check which mode I used on the string control or constant.

Hope this helps. Also always use the same number format as the documentation. If the documentation use hex format use the same format then coding

Thanks, it's working now. I've used the hex display of the string and now I can enter the hex commands and send it via the USB-I2C converter to the SRF08 sensor.
