Bug with HALL_TIMx_CC_IRQHandler()
file: hall_speed_pos_fdbk.c

There maybe a bug within this code:
if(pHandle->OVFCounter != 0U)
{
if(pHandle->RatioInc)
wCaptBuf = wCaptBuf * (hPrscBuf + 1)
...
else
wCaptBuf = wCaptBuf * (hPrscBuf + 1)
...
}
else
{
if(pHandle->RatioDec)
wCaptBuf = wCaptBuf * (hPrscBuf + 2)
...
else
wCaptBuf = wCaptBuf * (hPrscBuf + 1)
...
}
Consider the following code:
if(pHandle->OVFCounter != 0U)
{
if(pHandle->RatioDec)
wCaptBuf = wCaptBuf * (hPrscBuf + 1) + 0x10000UL
...
else if(pHandle->RatioInc)
wCaptBuf = wCaptBuf * (hPrscBuf + 1) - 0x10000UL
...
else
wCaptBuf = wCaptBuf * (hPrscBuf + 1)
...
}
else
{
if(pHandle->RatioInc)
wCaptBuf = wCaptBuf * (hPrscBuf)
...
else if(pHandle->RatioDec)
wCaptBuf = wCaptBuf * (hPrscBuf + 2)
...
else
wCaptBuf = wCaptBuf * (hPrscBuf + 1)
...
}
