Hi,
I made a small project using the ExpressVI's of the Digital Outputs of the myRIO.
Everytime I want to execute the program ( send it from my laptop to the myRIO) all the DO's are set. Is there a way to make it standard that all the DO's are false when the myRIO does a start-up?
thanks

When a bitfile is sent to the FPGA, all of the lines are tri-stated. If you want the lines to read false, I would recommend using a pull-down resistor on those lines. That way, when the lines are tri-stated, the DO lines get pulled to a '0'.
Best,

For more specific info check out the myRIO Specifications.
On the MXP ports DIO 0-13 have a 40K pull up resistor to 3.3v. DIO 14 and 15 have 2.2K pull ups resistors to 3.3v.
On the MXP port all DIO lines have a 40K pull down to ground.

What would the circuit diagram for that look like?

In your program add a intilize case for Set all the DO states false. So when you run the Code all the DO.s From my RIO Should Be in OFF state

Hi Kristoff,
I want to pull up my MXP port A and B. Can I do it programmatically? if not then what else I can do?
