DAC8775EVM: DAV8775 EVM Frist startup problems / basic adjustments

Hi,

It should be fairly straight forward to to enable the current or voltage output on the EVM. Refer to Table 3 in the EVM user's guide. Ensure that all of the jumpers are at their default positions then follow the steps below. The default mode uses a single power supply input to PVDD then the internal buck-boost generates the other rails.

1. Connect the USB-DIG to the EVM.

2. Connect a 12V-36V power supply to PVDD.

3. Perform a hardware reset by clicking reset at the top of the GUI.

4. Enable the reference.

5. Enable the buck-boost for channel A.

6. Select the output range for channel A.

7. Type the desired code and press enter.

8. Check the box 'output enable'.

You should then be able to measure the output based on the range you selected and the code. The same process applies for other channels. The full details of the EVM are described here:

Hi Garret,

thanks for the fast Response.

I checked all twice but after GUI reset same behaviour of labview program - all error states are on.

The worst thing is that i can´t collect any error Messages.

Is there the pos. to receive raw labiew vi code for implementation on my labview Environment (Labview 2017 SP1)..?

Best regards

Michael

Hi Garret,

Forget all things i wrote - seems USB cable was defective..sorry for the circumstances..
By the way is it possible to get the raw labview vi´s for implementation here ?

Best regards

Michael
