Interrupt is running, but what I see is that this interrupt goes 5x in the row, after comparator goes active. In the code, I set the default duty cycle is 50%, and it is forced to low when the CMPSS trip event occurs. For Cycle by Cycle Trip I've figured out a bunch of peripherals on C2000, but the trip zone stuff is the most confusing. bit. The PWM signals are forced to low using TZ if Vin (input ac voltage) is between -3<Vin<3 and it should then continue the regular PWM operation if Vin>3 or Vin<-3. red - PWMB. In the other hand, Piccolo indeed has less TZs than previos C28x series, that's because TZ4/5/6 are assigned to fixed fault like emulation fail and clock fail. GPIO12 (the external trigger) is routed to the input X-BAR, from which it is routed to TZ1. Nov 26, 2019 · I was told that had become an industry standard of ePWM modules. The CBC will be cleared at the event for which this is configured to happen These signals indicate external fault or trip conditions, and the ePWM outputs can be programmed to respond accordingly when faults occur. . I am trying to use the Trip Zone to create a CBC current limiting for TIDA-00951 Boost Mode, I an using TIDA-01281. Thanks 之前本来想用TZ1来捕获这个上升沿河下降沿的，但目前的问题datasheet中说明TZ1信号只有在由高变低的时候才会触发trip zone 从而产生相应的动作。 后来看到有人用DC数字比较器来触发，请问这个该怎么实现，看了一些例程的步骤 Nov 27, 2024 · Part Number: TMS320F2800156-Q1 Tool/software: HI expert. diuvn hrvvff kupk xnzle mijrn gsf idaeh fxcc epdj ozgfmqm zakya yxazxe dkegdt hdc woc
