i'm developing a software for a testbench.
(the hardware was developed in the past by another person, and i have to use this hardware now)
i have to read some digital data with a ni usb 6501.
i've measured the voltage levels on the pins and realized that for logical 1 I get about 4,7V, for logical 0 about 3,5V (which after converting into digital is still 1).
Do you have any idea how could I solve this problem?
I was thinking that if I could get somehow the analog voltage value on the pin, the problem would be solved, but I don' know if that's possible.
Thanks in advance.
Go to Solution.
on 6501 input low voltage (logical false) is up to 0.8V and input high voltag is in the range of 2.0V to 5.8V. You have to use a electrical circuit in or a device with a analog input order to solve this issue.
What do you think about a "Schmitt Trigger"
