TI 例程中 BLDC sensorless 怎么启动的,我运行例程电机怎么不转

是这段程序吗?没看明白,为什么pwm1.CmtnPointer只给0,有可能转不起来?

LOOP_CNT_MAX的初值是0,“ ”if (LoopCount != LOOP_CNT_MAX)  LoopCount++;  ” 这句好像永远也不会执行

// Initial Rotor Alignment Process
if (AlignFlag != 0)
{
mod1.Counter = 0;
pwm1.CmtnPointer = 0;
BLDCPWM_MACRO(1,2,3,pwm1)
if (VirtualTimer > 0x7FFE)
{ if (LoopCount != LOOP_CNT_MAX)
LoopCount++;
else 

AlignFlag = 0;
VirtualTimer = 0; 
VirtualTimer++;
VirtualTimer &= 0x00007FFF;
}
}
else
{
VirtualTimer++;
VirtualTimer &= 0x00007FFF;

}
else
{

// =============================== LEVEL 1 ======================================
// This Level describes the steps for a minimum system check-out which confirms 
// operation of system interrupts, some peripheral & target independent modules 
// and one peripheral dependent module. 
// ==============================================================================

#if (BUILDLEVEL==LEVEL1)

。。。。。。。。。。。。。。。。。。。

  • 先是电机开环转起来的 给固定的占空比

  • 我知道level1~level3都是开环转,但是 level1之前的那段程序,也就是前面我拷贝的那段程序是做什么用的?为什么我走Level1 电机也没转,需要改什么参数吗?EnableFlag已经置1,也能听到电流的声音,但电机不转.
