Hi, I connected the debug DAC8771. I connected a milliammeter to J7 to OUT and GND. With the help of the your program DAC8771EVM I try to adjust the output to 4-20mA. At the output, I always get 0. You can give step-by-step instructions (set JP) to get 4 mA at the output.
Hi Kost,
The default jumper positions can be found in Section 2.3 of the the EVM user's guide. The guide also explains how to operate the EVM:

Did you connect a 12-36V power supply to PVDD/AVDD?
In the EVM GUI enable the reference, set the power-off condition to High-Z, enable the buck-boost converter, select the current range, and click output enable. Then you should be able to write to the DAC data register and set the current output.
Thanks,
Garrett
