LAUNCHXL-F28069M: How to connect Resolver with Launchpad and TMDSRSLVR C2000 Resolver Kit

Part Number: LAUNCHXL-F28069M
Other Parts Discussed in Thread: TMDSRSLVR


I am trying to connect a resolver to a Launchpad 28069M using a "TMDSRSLVR C2000 Resolver to Digital Conversion Kit". I followed the hardware connection proposed by Mathworks

which was also recommended  in

I am able to generate the exciation using ePWM via GPIO2 and to read in the COS/SIN feedback voltages using ADCIN1A/B. Though, I am facing the problem that the SIN/COS voltages are in the range of +/-0.5V (1Vpp). As the Launchpad ADC's input voltage range is 0-3V the digital signals are equal to zero when the voltages are negative. Can somebody help me out here?

The alternative would be to insert a CPU (F28335) in the resolver board, let it do the resolver evaluation, and send the result to the launchpad via SPI. I am failing to implement this solution as well, as there is no documentation on the SPI signal sent by the resolver evaluation software so I do not know how to configure the receive block in Simulink. 

Can anyone support me in either one of these approaches?

Many thanks in advance
