Setting the Read/Write Bit in I2C Message
i need send ad hoc message sensor tell wake , measure, requires communication contains slave address , write bit (0) sent the
master. can standard data fetch.
i've spent hours looking on , can't see how send transmission only, have missed something?
tried variants of begintransmission, write etc. no avail.
so need send:
start, 7bit address, write(0), slave ack, stop
have tried begintransmission followed endtransmission? (dunno if work without write give shot).
the read or write bit set wire library.
