Cypress reset-signal for initiations

[Josv]

Hi,

Im trying to download my firmware to a Cypress chip through Labview. But my problem is how I should do for sending the reset-signal which the chip requires. My device is USB RAW and I can read some basic thing from the chip through Labview.

Hi Josv!

Communicating with the USB RAW class is more complicated because each device may use its own communication protocol. Contact your device vendor for details about the communication protocol for your device.

I know how the protocol looks like I’m able to "reset"

the chip from a C++ program. But now I want to build

an equivalent program in Labview...

Any suggestion?

Thanks,

hi Josv!

I assume your device is detected by Windows and NI-VISA is assigned as the device driver (binding done by .inf file) and you can see the device in MAX.

if thats the case, two additional VISA functions for USB, viUsbControlIn and viUsbControlOut can be used. These functions give you access to the USB device's control pipe, which every USB device has by default. You can set up communication with the device using the VISA properties. Refer to the NI-VISA Programmer Reference Manual, linked below, for more information on the USB specific attributes.

Hi,

I have never before written code in NI-VISA. How can I connect

NI-VISA to the graphical appearance which I'm used to in Labview.
