Programming C2000 for shift register74HC595 to control the relays thru SPI

Expert 1800 points

Greetings,

I wish to programme my 2812 DSC to control relays thru SPI and 74HC595 shift register.  I have CCS 3.3. 

The logic is to switch on the relays sequentially, one every second.  Connected the ser, rclk and serclk to the SPISIMO, GPIO and SPICLK ports of 2812 processor.

Any application notes or a sample programme would be of great help to me.  Please let me know if you need any more info.

thx & rgds
