we use a DS8500 as a HART modem in our transmitter.
we receive a extra 00 byte on FSK_OUT(DS8500) when RTSpin(DS8500)high to low.
String put on Din(DS8500): 12 11 AB 45 22 8A
receive string on FSK_OUT(DS8500):00 12 11 AB 45 22 8A
first extra 00 byte receive at the start of frame
we discard that byte or what can we do?
