| Abstract: | Using the resolver-to-digital converter AD2S82A,design a multi channel angle measuring system.Introduced the principle of this angel measuring system first. Then discussed the interface circuit between the AD2S82A and the DSP controller in detail.At last,gave a multi channel and high speed interface circuit which is composed of 3-state latches and monostable multivibratores. |
