配合X-BAR部分的介绍可知,ePWM的外部同步输入信号与输入X-BAR的INPUT5和INPUT6相连,此次我们选择EXTSYNCIN1作为ePWM模块的同步输入信号,因此需要将DSP上接收FPGA发送的中断触发信号的IO口配置到输入X-BAR上。 voidGPIO_SetupEXTSYNCIN1Gpio(Uint16pin){EALLOW;InputXbarRegs.INPUT5SELECT=pin;//Set XINT5 source t...

你好,我配置了TZ如下: InputxbarRegs.INPUT1SELECT =21;//把GPIO21 连接到TZ1 Epwm1Regs.TZSEL.bit.OSHT1=1;// TZ1作为Epwm1的中断触发事件 Epwm1Regs.TZEINT.bit.OST1=1;// 使能Epwm1的TZ中断
你好，你这里本来用于驱动电机的PWM波是如何生成的？
Configuring the comparators is different on F28075 as we have xbars of the device. So have a look at it to understand how to take the comparator trip to the PWM module and trip it in one shot manner. To modify it to CBC operation , i will suggest ...
