To excite Resolver, MCU should provide "sine wave" to resolver.
I could find out "SWG(sine wave generator)" in MCU at MCU of competitor .
Unfortunately I did not find out this module in TMS570.
How to implement this funtion at TMS570 ?
If you want to generate an analogue output signal you will need to use an external device. The TMS570 comes with lots of SPI interfaces so I would recommend using a DAC with an SPI interface provided that you don't need too high a frequency.
Page 3 of the MDK I/O development board schematic shows an example of hooking up the processor to a DAC. Schematics for the MDK development board can be downloaded from here: http://processors.wiki.ti.com/index.php/TMS570_MDK_Kit#MDK_Board_Schematic.
Obviously you will need to write the code to periodically send SPI signals to the DAC.
I hope this helps.
