 I need to implement the USBUART functionality for a project of mine and since I've never used it before I decided to try the USB_UART example project provided with psoc creator. I'm not sure what the program is supposed to be doing but I can not figure out step 4:

   

4. Install drivers for the device manually. In Windows 7, open "Device Manager", find the "USBUART" device in the "Other devices" branch of the tree. Open the context menu and select "Update Driver Software". Browse to USBUART_1_cdc.inf file from the project generated sources directory as a driver.

   

There is no branch labeled "Other devices" when psoc is plugged in so I am not sure where to update the drivers. I've also read about these drivers here http://www.cypress.com/?app=forum&id=2232&rID=89607 but I don't quite understand it. Where can I get those drivers and what does he mean when he says "the device is bound to CypressUsbAndBus.inf file"? Any help will be appreciated

   

Thanks!

Note, there are two USB connections on your Kit-001. The first one is for programming and debugging the board, while the second is connected to the PSoC directly supporting the USBUART.

   

Are you using a Kit-001 or a Kit-050?

Cypress has an SDK kit for USB development, which has the current

   

drivers. These drivers are for the windows side that allow win  to talk

   

to a USB device with a specific set of properties and ID.

When in .cydwr view to assign the pins there will be only one combination offered, probably P15_6 and p15_7.

   

There are no Rx and Tx pins in a USBUART component, it is a USB interface and on the PC side the UART com-port is emulated.

   

There are two USB connectors on your board, one is for programming the chip and debugging, the other is the USB interface of your PSoC5. You will need to connect both of them.
