DAC8568 + MCP23S17 SPI project

Projects General Guidance
1

Hi,

I'm wanting to do a project with both a DAC8568 (8 output DAC) and MCP23S17 (16 output digital expander). They are both compatible with the SPI bus. I already have had success with the MCP23S17, however I'm struggling to work out how the DAC8568 connects up with the standard MOSI, MISO, SCK and SS pins.

I'd really appreciate any guidance from anyone experience with the DAC8568 (or generally good with SPI projects).

many thanks
Paul :slight_smile:

P.S. Here's the datasheets:

I've also found this sample code for the DAC8568: Arduino Code for DAC8568 · GitHub

Hi Paul

From the datasheet, it looks like Arduino MOSI goes to DAC Din, Arduino SCK to DAC SCLK and Arduino SS to DAC SYNC.

Fantastic thanks. Will give it a try. :smiley:
