我使用的是demo是levelsense，我想把adc采样数据补0然后做fft。adc采样点我修改了64点，我补0到512点，然后对其进行FFT，我想着只需要修改其twiddle，就可以。我将附上没有修改前的代码和我修改后的代码，还有consolo报错日志。
1.修改前的代码：（twiddle初始化+使用FFT函数）
handle->twiddle = (float *)radarOsal_memAlloc((uint8_t) RADARMEMOSAL_HEAPTYPE_LL2, 0, 2 * handle->fft1DSize * sizeof(float), 8);
if (handle->twiddle == NULL)
{
*errorCode = RADARDEMO_HIGHACCURANGEPROC_FAIL_ALLOCATE_LOCALINSTMEM;
return (handle);
}
tw_gen_float(handle->twiddle, handle->fft1DSize);
void RADARDEMO_highAccuRangeProc_rangeEst(
IN RADARDEMO_highAccuRangeProc_handle *highAccuRangeHandle,
OUT float * estRange,
OUT float * estRange1,
OUT float * estRange2,
OUT float * deltaPhaseEst,
OUT float * estLinearSNR)
{

double freqFineEst, fdelta, interpIndx;
float currP, prevP, maxPrevP, maxNextP;
j = 30 - _norm(highAccuRangeHandle->fft1DSize);
if ((j & 1) == 0)
rad1D = 4;
else
rad1D = 2;
/* copy to scratch is needed because FFT function will corrupt the input. We need to preserve if for zoom-in FFT */
inputPtr = (__float2_t *) highAccuRangeHandle->inputSig;
inputPtr1 = (__float2_t *) &highAccuRangeHandle->scratchPad[2 * highAccuRangeHandle->fft1DSize];
for (i = 0; i < (int32_t)highAccuRangeHandle->fft1DSize; i++ )
{
f2input = _amem8_f2(inputPtr);
_amem8_f2(inputPtr1++) = f2input;
_amem8_f2(inputPtr) = _ftof2(_lof2(f2input), _hif2(f2input));
inputPtr++;
}
/* Do 1D FFT*/

2.修改后的代码：（twiddle初始化+使用FFT函数）
