Time-Base Counter Synchronization Scheme

Part Number: TMS320F28377D
Other Parts Discussed in Thread: C2000WARE

Hi,TI:

        According to the Figure 15-7. Time-Base Counter Synchronization Scheme on page 1876 of TMS320F28377D manual datasheet.

       In my project, PWM3 PWM4 PWM5 PWM6 are set to drive CLLLC ,how to configure the EPWM Time-Base Counter Synchronization?

THANK YOU!

                                                                     

  • 你好,可以参考TI提供的ePWM同步例程:epwm_ex3_synchronization,位置在:C:\ti\c2000\C2000Ware_3_04_00_00\driverlib\f2837xd\examples\cpu1\epwm

    需要注意的是,例程中是同步PWM1、2、3、4,根据TRM介绍,PWM1、2、3为一个同步源,同步源为PWM1。PWM4、5、6为一个同步源,同步源为PWM4

    所以,你的工程中需要注意的是,PWM3、4的同步源为PWM1,而PWM5、6的同步源为PWM4
