Part Number: TMDSRSLVR
I’d like to use the TMDSRSLVR kit for angular position sensing. Figure 2 of the following TI document indicates that it takes the R-Sin and the R-Cos signals as inputs, and the R-Excitation (R-Ex) as an output.www.ti.com/.../spry295.pdfBut my system’s angular resolver already generates the excitation signal by itself, so I don’t need the kit to output R-Ex. I wonder if the kit can measure my resolver’s R-Ex signal along with its R-Sin and R-Cos signals to measure the angular position and angular velocity.Best regards
Not a problem if you have another source for generating the excitation signal. Just use the Sine/Cos feedback signals. The challenge is to sync the ADC read of sine and cosine signals to the external carrier. The existing code does not support that right now, so you may have to come up with strategies for that.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to F.F:
If you had already installed controlsuite from TI, then you can see the example project supporting resolver using the resolver kit TMDSRSLVR at the following location
The core resolver algorithm is available as a library, where the library code takes care of generating exc signal as well as reading back the fbks and is internally synchronized. Source code is provided based on contacting us through the local TI sales.
