80 pin InstaSPIN Motion Chip TMS320F28069MPN

1. yes.

all mapping of peripherals is done in the hal.c / hal.h files

you can base your hal files for your inverter off of these

sw\modules\hal\boards\drv8312kit_revD\f28x\f2806x\src

I have a reply on another post about creating \solution\myinstaspin_foc that will be helpful to follow. You can either create your sw\modules\hal\boards\myboard or move the hal files into your solutions \src folder to keep all of your files that change in one location, making it easy to update the MotorWare drivers, modules, and any solutions files you want to re-use.

2. we wired this up for two reasons

a) the controlCARD interface supports multiple controlCARDs, and they all aren't identical with their layout.  We designed the DRV8312 EVM like 4 years ago...

b) in this case we were also setting it up so the evaluation board had some flexibility to use the 2-SH feature to grab different pairs of signals.  On the Piccolo devices you can only sample two signals simultaneously if they are on the same channel #, ex A1 and B1.  you can see in this case we made it so we could do

A1 + B1: Ia + Ib
A3 + B3: Ic + Ia
A5 + B5: Ic + Ib

this allows us to get any of the two best signal pairs when the third current isn't readable because the duty cycle is too low for the low side shunt.

HOWEVER - we aren't even using this for MotorWare InstaSPIN-FOC or -MOTION.  You will notice in HAL that we are simply taking all the currents, then voltages sequentially.  And we handle the determination of which of the currents to use outside the ADC sampling.

We have intention to update the ADC driver to use the 2SH feature....but as you can see, it isn't completely necessarily....it really only helps as frequencies get much faster and for higher short circuit motors (more current ripple)....if even then.

For your design, you just need to get the 2-3 currents, 3 phase and 1 bus voltage to the ADC pins, and then set-up your hal file appropriately.

The key thing is getting the values into pAdcData-> in the correct order (Iu, Iv, Iw, Vu, Vv, Vw, Vbus).

Thanks Chris. I identified one place that I believe should change in hal.c line 850

  return;
} // end of HAL_setupAdcs() function

Are there other places that require the change? Some ADC inputs are not available in the 80 pin version (A3,A7, B3, B7).  Are there any read commands for those that need to be disabled? I am new to hal.c and hal.h. Your input is highly appreciated.

Thanks,
Sina

yes, if just changing which pins are connected to Iu, Iv, Iw, Vu, Vw, Vw, Vbus you have the right section.
