WEBENCH® Tools/DAC8742HEVM: DAC8742HEVM H/W setting about HART and GUI read/write

Part Number: DAC8742HEVM

Tool/software: WEBENCH® Design Tools

Hello,

I'm using DAC8742HEVM with SPI & HART interface. I set H/W and GUI program for HART with UART.(blew picture)

It does not work like I think. By accident when I set same the picture, HART read data. But when I reset GUI program, it does not read data again.

I would really appreciate some additional documentation of the tool or some valid working examples.

Best regards

Hi Mayikol,

I am not sure I exactly understand your issue. What do you mean when you reset it does not read data again?

Do you have MODIN and MODOUT tied together? You can test the read by connecting MODIN to MODOUT, enabling full-duplex, and clicking 'generate read' after 'generate write'. Also, you should enable the internal bandpass filter.

Thanks,
Garrett
