DAC8742HEVM: How to configure the EVM to communicate with SPI

Part Number: DAC8742HEVM
Other Parts Discussed in Thread: USB2ANY

Hi,

I wanted to communicate to the DAC8742HEVM with another microcontroller through SPI interface, and at the same time wanted to still have it connected to the USB2ANY interface so i can observe the transactions on the PC.  Is this even possible, and if so, would you please indicate which jumpers to connect to?  I was reading through SLAU700a documentation but could not find any reference on how such configuration can be carried out.  Thanks in advance for any inputs!

Regards,

Jay

    Hi,

    Thanks for reaching us.  i will help you on this request.

    1. Use can use (1) J6 connector to connect your own micro controller SPI signals and use JP4 jumper position (1-2) to disable the USB2ANY interface then drive from your MCU.

    2. Want to use USB2ANY interface, disable chip select from micro controller and enable JP4 jumper postion (2-3) and use USB2ANY interface.

    make sure IOVDD should be same for both interface 

    Thanks .
