Hi,

   

I have a temperature sensor LM74. It has 3-wire spi. I want to communicate it with PSOC.

   

It would be very nice if you can guide me, how i can do this.

   

Looking forward to hearing from you.

   

Regards

Check out this related thread: http://www.cypress.com/forum/psoc-4-ble/3-wire-spi-bidirectional-half-duplex-issue

   

​It works similar to a regular SPI interface, except there is only one data line.

   

Here is assistance on using the SPI interface: http://www.cypress.com/documentation/component-datasheets/serial-peripheral-interface-spi-master

   

​I would suggest doing some example SPI interfaces before switching straight to 3-wire so that you understand what the component is doing.
