Software handshaking for USB-6009 in DO

[mihalis]

Hello!

I need help!

I use USB-6009 with my device. The USB-6009 out 8 bit parallel data to device 3 time per second. How a can do software handshaking, in order to USB-6009  tell to my device, thats byte is true on USB-6009  port ? Or how my device know, that data value has been write out at USB-6009 port ?

Thank you!

Hello Voltage V… !

My USB-6009 interfacing whith microcontroller system,  therefore it support any asynchronous protocols. I programming microcontroller myself.

I know, that I want use an additional line on 6009 as a "data ready" signal, bat a do not know, how it make by LabVIEW. I use write dig port.vi for didgital data out. How i can modify myLabVIEW vi for software handshaking ? Is example ?
