TLV5614 interfacing with TMS570LS3137

Hi All,

I want to interface TLV5614 DAC with any of the MibSPIs of TMS570LS3137. Is it possible? How to connect FS pin to TMS570. Please provide me with an example block diagram and example code on how to ahieve this interfacing?

Thanks

    Pradeep,

    We do not have any sample code specifically prepared for the TLV5614 interfacing the TMS570LS3137. As far as the TMS570LS3137 is concerned, though, this is a pretty straight forward 16-bit SPI bus with clock polarity 0 and phase 1 (clock idles low and data is latched on the falling edge). I would suggest you post on the TMS570LS3137 forum and ask for sample code for using the TMS570LS3137 MibSPI peripheral in this fashion.

    Concerning the TLV5614 - FS can more or less behaves in the same way as the chip select signal from the TMS570LS3137. You can then use a GPIO to control the TLV5614 CS pin or just ground the TLV5614 CS pin depending on what your application looks like. The datasheet illustrates the GPIO case in Figure 18 with the TMS320C203.
