Piccolo 28069

Hi Chris,

I've tried the projects in the DRV8312-C2-KIT, but they won't build for F28069

Do you then have a similar project that is targeted only for F28069 (TMDX28069USB?) ?

Thanks 

Kind Regards,

Oscar

Hi Chris,

now it builds fine : )

thanks

I reinstalled controlSUITE, and restarted CCS

there was an unrelated error (w/c escapes me at the moment) on the first build

next question: will this suffice for incremental build level 1 ?

Kind Regards,

Oscar 

Oscar,

are you talking about the red text that scrolls by before it completes build? That happens because there are files it is trying to delete/clean from the release directory that aren't there if you have never built the program before. Once you have built once you won't see those.

I built build level 1 and 7 without issue.

Hi Chris,

indeed, those texts plus something else

and yes, build level 1 is functional, except that I only got 3 PWM channels, despite another CCS issue (probably another newbie error)

EPWM3A - Active, EPWM3B - Low

EPWM2A - Active, EPWM2B - Low

EPWM1A - Active, EPWM1B - Low

is TI releasing project versions of;

HVACI_Scalar

HVACI_Sensored

HVACI_Sensorless

for F28069, in the coming weeks ?

thanks

Kind Regards,

Oscar

Oscar,

you only see 3 pwms because the DRV8312 only needs high side PWM, it creates the lowside itself.

For 6 PWM look at the DRV830x examples. That PM_Sensorless project is also dual built for F28069 and runs fine.

We don't have plans for F28069 on the HVKit at this time.  There is support for the F28335 which is very similar. It would not be difficult to port one of those projects to F28069.

Hi Chris,

The DRV830x PM_Sensorless project indeed works

It outputs a smooth 50 Hz AC, from 10kHz PWM

However I could only run it properly (per one time run) by cleaning the project folder & workspace everytime... probably due to a different code present on flash

Therefore, does the project have an entirely separate flash build configuration ?  

Thanks

Kind Regards,

Oscar

ps> unfortunately, I couldn't even imagine how to port F28335 ACI code to F28069, but I'm open to further wikis : )

No there isn't, but you can follow the appnotes on how to move from a RAM project to Flash. You will need to learn these things to progress in a project.

Hi Chris,

Thanks for the inputs.  I could successfully run the level 1 code with F28069 kit.  However I wanted to migrate to sensored PMSM 3_1 then realised that a lot needs to be changed to use with power boards built similar to DMC1500.  For normal mortals like me it would take a lot of time.

I checked at the development kits path in controlsuite directory and found codes for BLDC sensored, BLDC sensorless and PMSM sensorless.  But there is no code for PMSM sensored wonder why TI has not considered this application.  I would suggest TI to take up this application also and thus help many more who would like to develop applications based on PMSM3_1.

Pl review and suggest.

thx & rgds

PM Sensored High Voltage (like DMC1500) available through F28035 and HVKit

C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v1.6\HVPM_Sensored

Thanks Chris for the info.  Could I replace / copy relevant HVPM_Sensored.c into PM_Sensorless.c and start trying the code?. 

Do you suggest I need to change any other files / settings?.

Pl advice.

thx & rgds

Hi Chris,

I figure this "HVACI-F28069" project would work except for the "SVGEN_MACRO(svgen_dq1)" issue... please see "CCS view" below

Would you know a straightforward fix for this "build error" ?

Thanks

Kind Regards,

Oscar

1. I assume you created your own F2806x motor_control/drivers ?

2. The error is that IQdiv2 and IQmpy2 aren't defined.

Where are you using these?  They were never used in any project in the HVMTR Kit.

This is strange though, they are defined in IQMath library.

maybe something to do with the improper memory location of the ROM table it uses?

__IQdiv2 and __IQmpy2 are macros defined in IQMathLib.h. if its included in HVACI_Sensorless.h it should work fine. The fact that the linker thinks its a callable function seems to indicate that it hasnt been included.....

IQmathLib.h is included in HVACI_Sensorless.c along with HVACI_Sensorless.h (true for all HV & DRV projects)... placing it in HVACI_Sensorless.h yields a different set of errors

The location of the IQ tables in ROM is similar to that of DRV830x - PM_Sensorless project

IQdiv2 & IQmpy2, I understand, are used in all FOC projects, via SVGEN

The motor control drivers, on the other hand, are adapted from the F2833x set (or F2803x set)   

this attempt is difficult it feels like REM's losing my religion : )

perhaps only TI can make HVACI-F28069 work
