CCS/TMS320F28379D: How use example MonoMtrServo_377s_v1_00_00_00 with Launchpad f28379D and boostxl-DRV8305?

Tool/software: Code Composer Studio

I am working with the example MonoMtrServo_377s_v1_00_00_00 Available in Control suite, but I'm using launchpad f28379D and boostxl-DRV8305. I'm already changed configuration of pins. My question is, Must I import another library for working with these elements? Because the files inside the example folder are named f2837XS, this can cause errors? Also, I'm having trouble with conditional structs, it seems the code is not identifying the launchPad, because it isn't going into this struct.

#ifdef LaunchPad379D //Sanmesh same PPB number of different ADC modules used
AdccRegs.ADCPPB1OFFREF = motor1.offset_shntA*4096.0; // set shunt Iu1 offset
AdcbRegs.ADCPPB1OFFREF = motor1.offset_shntB*4096.0; // set shunt Iv1 offset
AdcaRegs.ADCPPB3OFFREF = motor1.offset_shntC*4096.0;

Can Someone help me ? Thanks

You can switch the header files to the F2837xD ones if you want (the devices are similar enough that you probably won't run into any build errors), but the F2837xS includes should work okay for now. The main difference between the two is the extra CPU which shouldn't matter here.

Are you saying your #ifdefs aren't working? You added them yourself when you were updating the pin configurations (I don't see them in the original), right? Where are you defining "LaunchPad379D"?

I'm understand. About #ifdefs, I'm have found in this code: https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/171/MonoMtrServo.c , I'm used that code for adjust 379D pins.

That code doesn't actually define LaunchPad379D anywhere. You should either #define it at the top of that file or put it in your compiler options as a predefined symbol.

I'm understand.Thanks Whitney.

So,do you recommend do that in original file of MonoMtrServo_377s_v1_00_00_00? How can I define that using "#define" like you say? After define this, there is some function wich I have to use, for enable the DVR8305, or all I need it's already contain in that code ?

You just need to put a line like "#define LaunchPad379D" somewhere in your code before any of the #ifdefs. You could consider putting the line in MonoMtrServo-Settings.h with the other #defines or at the top of the MonoMtrServo.c file.

To use the DRV8305, I think you need to modify the MOTOR1_DRV #define in MonoMtrServo-Settings.h to set its value from DRV8301 to DRV8305 if it is not set already.

I set Motor1_drv in MonoMtrServo-Settings.h, like below:

#define MOTOR1_DRV DRV8305

Even this, the code are still not identifying the DRV8305, because the expression "MOTOR1_EN_GATE_GPIO" it's defined unknown,so the DRV8305 can not be enable.

Beside that, the code it isn't going intro in conditional struct in line 1046 to verify DRV8305.

Is there a program required to enable drv? In the datasheet of DRV8305 is enabled through a tool called Instaspin.

I'm not following what issue you're seeing. I've rebuilt the example with MOTOR1_DRV defined as DRV8305 and could see MOTOR1_EN_GATE_GPIO being defined as 72. I don't see anything wrong with C1() either except for the value of tmp2 never being used which isn't necessarily an issue. Are you not able to build the code? Or is it not executing correctly when you run it? Can you elaborate?

The F28379D doesn't support InstaSPIN.

The code is not executing correctly, because when code is running, MOTOR1_EN_GATE_GPIO isn't being defined as 72.

0 Whitney Dewey over 6 years ago in reply to Mateus Lopes

TI__Guru 54625 points

How are you determining it's incorrect? Are you stepping into the call to GPIO_WritePin() that uses it and seeing the wrong pin being set?

When the code is running, the variable MOTOR1_EN_GATE_GPIO is unknown and its value is "identifier not found".

It's a #define, not a variable. It just gets used at compile time as a constant. It's not actually allocated space in memory, so you can't view it in the expressions window like you would an actual variable.
