TMS320F28069M: Description for architecture of motorware in C

Rasool Haghi

Part Number: TMS320F28069M
Other Parts Discussed in Thread: MOTORWARE, DRV8301

Tool/software:

Hello, Are there any document or descriptions around architecture of the C code that in provided for Motoroware?

I am looking for documents which clearly describe every sub function for the code. F.ex. HAL_HANDLE following that how it can configure MCU pins ...

Thanks in Advance.

You may take a look at InstaSPIN-FOC and InstaSPIN-MOTION User's Guide ( https://www.ti.com/lit/spruhj1)

Thanks for reply. I already saw that description. But problem is the very complex body of the MotorWare Code. plenty of pointers are using that is confusing.

For instnase, I would like to know what is the intention of below code:

typedef struct _HAL_Obj_ *HAL_Handle;

Is "HAL_Handle" defined as pointer wich is points to _HAL_Obj_?

If yes, what is the founction of "typedef struct" at the beginig? If you look on to the code, there are another "typedef struct" which is defined a couple of line before.

So there is two "typedef struct _HAL_Obj_" in one code.

typedef struct _HAL_Obj_

{

ADC_Handle adcHandle; //!< the ADC handle

CLK_Handle clkHandle; //!< the clock handle

CPU_Handle cpuHandle; //!< the CPU handle

FLASH_Handle flashHandle; //!< the flash handle

GPIO_Handle gpioHandle; //!< the GPIO handle

OFFSET_Handle offsetHandle_I[3]; //!< the handles for the current offset estimators

OFFSET_Obj offset_I[3]; //!< the current offset objects

OFFSET_Handle offsetHandle_V[3]; //!< the handles for the voltage offset estimators

OFFSET_Obj offset_V[3]; //!< the voltage offset objects

OSC_Handle oscHandle; //!< the oscillator handle

PIE_Handle pieHandle; //<! the PIE handle

PLL_Handle pllHandle; //!< the PLL handle

PWM_Handle pwmHandle[3]; //<! the PWM handles

PWMDAC_Handle pwmDacHandle[3]; //<! the PWMDAC handles

PWR_Handle pwrHandle; //<! the power handle

TIMER_Handle timerHandle[3]; //<! the timer handles

WDOG_Handle wdogHandle; //!< the watchdog handle

HAL_AdcData_t adcBias; //!< the ADC bias

_iq current_sf; //!< the current scale factor, amps_pu/cnt

_iq voltage_sf; //!< the voltage scale factor, volts_pu/cnt

uint_least8_t numCurrentSensors; //!< the number of current sensors

uint_least8_t numVoltageSensors; //!< the number of voltage sensors

SPI_Handle spiAHandle; //!< the SPI handle

SPI_Handle spiBHandle; //!< the SPI handle

DRV8301_Handle drv8301Handle; //!< the drv8301 interface handle

DRV8301_Obj drv8301; //!< the drv8301 interface object

#ifdef QEP

QEP_Handle qepHandle[2]; //!< the QEP handles

#endif

} HAL_Obj;

Yes as the source code that could be clear to link the object.

Just for the same one as the typical definition a struct object. You may find the detailed description about this in a C language textbook.
