Today, I fetched some new waveforms at TXD1 and TXD2 of MCU( while not for AD5700) under (NONE/EVEN/ODD mode. as below:
I still get incorrect data from HART bus when I send one byte as path :MCU-AD5700-AD5421-LOOP, for exampe, when I send 0xA8 from MCU every second, I will get HART data(form 4-20mA LOOP) as: 0x28/0x68/0xA8
I still don't know how to solve this issue. can anyone tell me why? please.
