A error about STM32F0xx_StdPeriph_Lib_V1.4.0 of TIM_6Steps???

Question asked by yongfei.liu on Feb 15, 2015
hello every body,
    I,recently,would like to implement 6 steps output with STM32F0xx_StdPeriph_Lib_V1.4.0/Projects/STM32F0xx_StdPeriph_Examples/TIM/TIM_6Steps, but the output waveforms corresponding to above souece code downloaded to  the stm32f0discovery development board seem to be incorrect,according to the control theory about BLDC. However, the waveforms measured by oscilloscope corresponding to STM32F10x_StdPeriph_Lib_V3.5.0/Project/STM32F10x_StdPeriph_Examples/TIM/6Steps is consistent with the  the control theory about BLDC.
    Dose  the  stm32f0discovery development  development board   occurres error or Is the  souece code in the  STM32F0xx_StdPeriph_Lib_V1.4.0 error????? 
    The waveform about STM32F0xx_StdPeriph_Lib_V1.4.0 and STM32F10x_StdPeriph_Lib_V3.5.0 is in the attachment.
                                                                            the best wishes with you!!!!!!!!!!!
