Part Number:DAC8742HEVM
Hello,
I'm using DAC8742HEVM with SPI & HART interface and I would like to generate master request to my sensor (SEM315 MKII with PT100) - preferably sending HART command 0 using the board & GUI. The problem is that DAC8742HEVM GUI is insufficiently documented and creating valid HART frame seems to be a problem. There is no information on how HART frame is created via GUI. I've tried sending data on multiple ways - starting from preambles, delimimiter etc. Seems that 'raw' frame should be correct (from preambles to the check byte), but unfortunatelly sensor could not respond to that.
I can observe message on the oscilloscope and it looks like that after HART frame there are added a lot of ones, could that be the problem?
I would really appreciate some additional documentation of the tool or some valid working examples.
Best regards
