Hi Anthony,

"Greeting"

one of our team member already in discussion with you for trapezoidal hall based motor and i am working on encoder based motors..

we support for  port Instaspin with encoder or sensor less..

thanks in advance for support..

Hi Antony,

please find attachment our DRV8323 custom board...

Are you planning to build a custom board?

Yes we make break out board which will attach with LAUNCHXL TMS320F280049C...
that breakup board connect to our DRV8323 custom board.

Herewith attached Launchxlf280049c with drv8323Rs for your kind reference..

Hi Ajay, 

I double checked your connections based on the excel sheet and everything looks good except for ISENSA and ISENSC. ISENSA needs to be connected to PGA5_IN and ISENSC needs to be connected to PGA1_IN. Once that change is made then the C2000 team can help you with any changes that will be necessary in the software.

Anthony 

Hi.., Anthony,

we have changed  ISENSA and ISENSC connection in our break out board soldering....

kindly guide to start porting instaspin source code..

Hi Ajay,

I have looped in the C2000 team to this thread and they will help you with that.

Hi.. Lodi and Yanming,,

thanks sharing document ..we startinng porting HAL layers..

We want to port project Drv8323 with encoder instapin foc... not sensorless..

Dear Mr.Lodi..
with respect to document spruij3a.pdf... PGA1_IN    is ISENSA...
PGA5_IN is ISENSC....

But i am following as per reply... but kindky confirm i can follow hardware porting,  with respect to spruij3a.pdf..
only CAL and 

pins are difference  between DRV8320 and  DRV8323...

Ajay..

Hi.. Yanming Luo..

kindly guide us.. Instapsin encoder based program...

We plan to test upto13 lab program instaspin with our machine load.. including lab with  dual motor and Field Weakening and Maximum Torque per Ampere Control..

Because our end product load to motor is vary dynamically.. i cant share end product in open forum...

I already tested application delfino79d with ganfet and launchpad 49c with drv8320rs instaspin...

but based on trial for our load.. Instaspin is better in tunning for motor load and easy for us quick tp market as soon as.....but  positioning is one of our major requirement.. so that instaspin with encoder based..

when i was working  launchpad 49c with drv8320rs evm instaspin its sensorless means what is purpose of encoder lines in parameter???

we developed DRV8323rs custom board(trapezoidal) for another application. now we plan to use same custom  drv8323rs for  new application also..

Texas Instrument provide lauchpad69m with drv8323 in slvc705.zip...
 I can to use same project  for lauchpad49c.. what are files to be added and how i can test instaspin labs from 5a to 13...form lauchpad69m project file...

Hi Ajay, 

I apologize for the confusion, it looks like there is a mistake on the pinout table in spruij3a.pdf in regards to ISENC and ISENA. I have attached a document based on the schematic of the BOOSTXL DRV8320RS and the pinout of the LAUNCHXL F280049C to explain which pins are used to connect the ISENA and ISENC signals.

Anthony
