Other Parts Discussed in Thread: TIDM-02014
Tool/software:
Dear TI Team:
When I use Infineon,I use DSADC Module to get sinθ and cosθ value through the process in below picture.However,I don't find any usage of DAC and SDFM module in TI sofware resolver decoding refernence design in such as TIDM-02014.It seems we need to devote more efforts to builing software codes instead of relying hardware module.In Infineon,I just pay attentaion to DSADC register configuration,after the initiation of DSADC module,I just only need to get sinθ and cosθ periodly without any other too much software process.So it will not cause too much burden to software running process.
Therefore,I am curious that why TI use "Discrete Resolver Front-End" solution without any usge of DAC and SDFM module which is similar as DSADC Module in Infineon.And I also see description such as"The sigma delta filter module (SDFM) is a four-channel digital filter designed specifically for current measurement and resolver position decoding in motor control applications."in SDFM chapter of user mannual.
why does TI software resolver decoding has no usage of DAC and SDFM module?
