I would like to use the AD9837 with an ATtiny1634. I'm not sure were to start with it or setting up the SPI link between the ICs.
Can anyone offer any advice or C code examples for how to use this?
Are you going to
(1) use the AD9837 evaluation board but using a different microcontroller, or
(2) are you going to design your own board?
If (1), just take note of the test points SCLK, SDATA and FSYNC in the eval board. The board has the option to be used for SDP-B boards, but can also be used as stand-alone daughter board using external microcontroller. You just tap on the data line test points provided.
If (2), I suggest you make eval schematic as reference but having data lines connected to your ATtiny1634 SPI data lines. Also, kindly give careful consideration on the layout esp on grounding, and digital and analog isolation. You can refer to the datasheet for more info. About the code, the algorithm is very straightforward. Your reference for this will be: AN-1070
