DRV8312-69M-KIT: Sensor (Resolver) connection to the Boosterpack
Part Number: TMS320F28379D
I have resolver for sensing speed and LaunchPad TMS320F28379D for PMSM control.
As resolver can't be connected to QEP module as former is analog and later is digital. so, how to connect resolver to Launchpad.
I read in the manual about "Sigma Delta Filter Module" but i ended up being more confused, that "Do i have to use this for resolver or it is only for current sensing? "
Any help will be appreciated.
Thank you in advance.
SDFM is alternate way of getting analog signal values brought into digital domain, a parallel to ADC. They are not limited to just current sensing.
SDFM is a filter module that filters the bit stream coming out of the modulator (that converts analog signals into digital) and the filtered output represents the converted data. There is more literature on it available in the web fyi.
To use resolver along with the launch pad, there is a booster pack available http://www.ti.com/tool/BOOSTXL-POSMGR. This can interface to various encoders including resolver.
There is no software available just for this platform, but can be ported over from example projects available at
Hope it helps.
