| Abstract: | Using the resolver-to-digital converter AD2S82A, designed a multi channel angle measuring system. The paper introduced the principled of this angel measuring system first, then discussed the interface circuit between AD2S82A and DSP controller in detail. At last, given a multi channel and high speed interface circuit which is composed of 3-state latches and monostable muhivibratores. |
