or as an USB device which communicate using text based communication & use VISA VIs.
Please reply as soon as possible
Thanks & Regards
A quick search of USB 8451 turned up the following links:
The last one has a link to the programming manual at the bottom.
In one of our application I have to read the internal register values of the sensors. I am using NI 8451 card.
Pin Details of the sensors are-
My question is NI 8451 is having separate pins for SDO & SDI But sensor is having one pin for SDIO. How to connect them ,I have to read the register values & some registers are read/writable.??
Please reply as soon as possible, it is very urgent
How can we configure the spi frequency of operation for NI-USB-8451
I am developing a testing tool which requires the data to come from PC instead of a card reader which speaks to the testing device on spi.
however different card readers speak on different spi frequency and i need that to be configurable. Can this be done in lab view. And I need some more i/o signalling along with the spi. Is this possible.
The 8451 SPI frequency is set the "NI-845x SPI Script Clock Rate" VI. Check out Chapter 8 of the software manual.
In terms of "more I/O signaling" the 8451 has 8 general purpose digital I/O lines. This information is in the User Guide and Specifications.
