Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE, CONTROLSUITE

Dear Sir,

I am new for TI processors, usually familiar with NXP before.

I want to make the Motor Control Unit with MATLAB/Simulink via Code Generation Process.

In my experience, I usually write the *.c *.h files for peripheral devices like EEPROM, Watchdog, SBC, etc.

Which it requires access to hardware resource via low level function like SPI send, SPI recieve, GPIOs, etc.

Now, I migrate to TI processor, Could anyone give me start point project for this purpose ?

How does I get these low level function resources and header files?

How does the hardware support package of TI in Simulink work in this senario?

Finally how should I flash this project into board ?

(I have the XDS110 debug prove in hand)

Best Regards,

Narudol T.

Hi,

You can go through C2000 Academy to get started with C2000 devices.

https://dev.ti.com/tirex/explore/node?node=AOpze8ebskysmgASY3VKSA__jEBbtmC__LATEST

C2000 Academy requires C2000Ware installed. The SDK includes lot of examples for all peripherals.

Here is link to started with MathWorks Simulink for C2000 devices

https://www.mathworks.com/help/supportpkg/texasinstrumentsc2000/ug/getting-started-example.html

Let me know if you need further assistance in getting started.

Dear SanTosh,

Thank you for your quick reply. I think I do not explain it well.

I do have experience on the simulink and customed code before with NXP product.

Now, my problem is that I do not know the "function" which I should call for the purpose like blink LED.

By the way after I look into code generation files, I saw included *.c as below

Generated Code

[-]

Main file

ert_main.c

[-]

Model files

devkit_F28069_TICK.c

devkit_F28069_TICK.h

devkit_F28069_TICK_private.h

devkit_F28069_TICK_types.h

[-]

Utility files

rtwtypes.h

[-]

Interface files

rtmodel.h

I think this file should contain my needed function, right ?

Most of them located in C:\ti\controlSUITE\device_support\(Target Device)\....

But I cannot find the MW_c28xGPIO.c and others MW_xxxx at all.

However, as MATLAB allow me to read this files, I saw that this c code.

Inside the MW_c28xGPIO.c there are GPIO relates function like "GPIO_WritePin".

So, CAn I just call-out this function in my custom c-code to use it ?

/*Set the GPyDAT register bit for the specified pin.*/
void GPIO_WritePin(Uint16 pin, Uint16 outVal)
{
volatile Uint32 *gpioDataReg;
Uint32 pinMask;

#ifdef MW_PIL_TIC2000_CONCERTO
if (pin >= 128)
{
#ifdef F28M36x_DEVICE_H
if (pin <= 135)
{
gpioDataReg = (Uint32 *)&GpioDataRegs + (0x40/2);
}
else if (pin >=192 && pin <= 199)
{
gpioDataReg = (Uint32 *)&GpioDataRegs + (0x10C0/2);
}
#endif //End of F28M36x_DEVICE_H
#ifdef F28M35x_DEVICE_H
if (pin <= 135)
{
gpioDataReg = (Uint32 *)&GpioDataRegs + (0x1000/2);
}
#endif //End of F28M35x_DEVICE_H
}
else
{
#ifdef F28M36x_DEVICE_H
gpioDataReg = (Uint32 *)&GpioDataRegs + (0xC0/2) + (pin/32)*GPY_DATA_OFFSET;
#endif //End of F28M36x_DEVICE_H
#ifdef F28M35x_DEVICE_H
gpioDataReg = (Uint32 *)&GpioDataRegs + (pin/32)*GPY_DATA_OFFSET;
#endif //End of F28M35x_DEVICE_H
}
#else
gpioDataReg = (volatile Uint32 *)&GpioDataRegs + (pin/32)*GPY_DATA_OFFSET;
#endif // End of MW_PIL_TIC2000_CONCERTO
pinMask = 1UL << (pin % 32);

if (outVal == 0)
gpioDataReg[GPYCLEAR] = pinMask;
else
gpioDataReg[GPYSET] = pinMask;
}

Hi,

Looks like you are using a wrong device. My understanding from the subject is you are looking for Simulink model on F28379D device, but looks like you have F2806x .h/.c files.

There is YouTube Video which walks through the steps needed to

Please take a look, if it helps you.
