Reading data from USB based EEG device

[Vishwasd19]

Hello,

I have an EEG system that gives data via a USB endpoint, the device uses a cypress driver. I needed to read real-time data into MATLAB, I was wondering if we could do this using LabVIEW. If yes, can you tell me how?

So your devices uses a Cypress chip? Which one? Is it a virtual COMM device that simply installs in Windows as a serial port (if you have the correct driver installed)? For instance one of the CY7C652xx class?

If so then yes you can but there is a big but! Do you have the documentation for the command set of your device? Without that you could just as well try to talk to your fridge in your kitchen, it may or may not have some controller in it that can be communicated with.

Also note that the Cypress chips support other than UART mode such as I2C, SPI and GPIO. If your device uses one of these special purpose interfaces rather than the UART mode, things get more complicated as you can't just use VISA to talk to the serial interface but instead have to interface to the Cypress DLL to access the according interface functionality of the chip. (And the likelyhood to find proper documentation about the used protocol approaches usually 0% in that case).
