I would like to program the AD9914 eval board over SPI with a microcontroller.
I don't understand why it doesn't work, because my SPI interpreter decodes any good values.
I have attached a screenshot of my SPI diagrams (DAC calibration).
Thanks for your help,
I have started to work on your suggestions,
If you're trying to program the AD9914 evaluation board externally, I would first try something simple like program the AD9914 to disable…
have you managed to control AD9914 with SPI? I am currently facing the same problems and have exactly the same questions. Could you please share with your experience?
Thanks in advance!
If you're trying to program the AD9914 evaluation board externally, I would first try something simple like program the AD9914 to disable the SYNC_CLK at SMA connector J100 . That way, you could simply monitor the SYNC_CLK SMA connector for ON/OFF operation. The SYNC_CLK defaults to enable. To disable the SYNC_CLK write to register 0x01 register bit 11."
I have managed via a simple SPI library in the ARDUINO to output an address of 0x01 the value 0b11 (see picture attached)
regarding point 1) Practically does it mean that I put the jumpers of P205=Enable, P203=Disable, P204=Enable?
Where do I connect onto the Evaluation board the SCLK, SDIO. Currently it is on the MPI01 and MPI02 Header. Is this correct?
Do I use the IOUPDATE input as it is mention on the evaluation board Header?
What do I do with the other jumper, do I keep them as default on the two Headers?
Many thanks in advance
