Abstract

PURPOSE:To make data communication bidirectionally and asynchronously with a simple constitution, by inserting a flip-flop between control lines, in a bidirectional data communication using two signal lines in addition to a power source and a ground line. CONSTITUTION:Microcomputers 11 and 12 are mutually connected with a data line 14 and a clock line 15 and a flip-flop 13 is inserted in the clock line 15. In transmitting and receiving data, a control signal is outputted from the microcomputer 11 to invert the flip-flop and the microcomputer 12 is switched to an input mode for data communication. The transmission/reception of data can bidirectionally be made by making this control alternately.
