IO pin's status send to USB (need sample code...)

Sorry for my english.

Controller - cy7c6801 - 56pins.

From the examples I do not understand how you can easily convey the state of input-output ports on the usb in my application. If not hard - give a simple example for learning (very desirable in the C language).
Thanks in advance!

Hi,

The part number that you had mentioned is incomplete. I believe you are using FX2LP (CY7C68013). If so, for using the various IO pins as GPIOs, you can refer section 11.9 in the EZ-USB Technical reference manual, which you can find at " \Cypress\USB\doc\FX2LP " after installing FX2LP DVK (http://www.cypress.com/?rID=14321)

Regards,

Gayathri

Thank you - good example..

Yes controller cy7c68013 - 56 Pins
With the transfer of data from the ports figured out.

I can not find an example of software implementation of SPI interface - specifically found only AN14558 document but there is no source projects, and the realization I did not like.

Help? :)

I wrote a pilot project based on third-party sources - - such as working fine:)
