| Abstract: | A method for interfacing single chip computer 8031and 3-line serial bus devices is presented in this paper based on analysis of the timing sequences of a typical device MAX 531 (12-bit DAC). As an example, an intelligent temperature instrument for molten metal measurement composed of MAX 531 is described. The input digital quantity formula is also given. |
