关于epwm_deadband这个例程

例程就是这样配置的下面是我的文档中关于这个例程的说明。

4.14 ePWM Deadband Generation (epwm_deadband)
This example configures ePWM1, ePWM2 and ePWM3 for:
• Count up/down
• Deadband 3 Examples are included:
• ePWM1: Active low PWMs
• ePWM2: Active low complementary PWMs
• ePWM3: Active high complementary PWMs
Each ePWM is configured to interrupt on the 3rd zero event when this happens the deadband
is modified such that 0 <= DB <= DB_MAX. That is, the deadband will move up and down
between 0 and the maximum value.
External Connections
• EPWM1A is on GPIO0
• EPWM1B is on GPIO1
• EPWM2A is on GPIO2
• EPWM2B is on GPIO3
• EPWM3A is on GPIO4
• EPWM3B is on GPIO5

hongyue,

这个例程主要是诠释piccolo的死区模块的设置的灵活性，你可以通过查看epwm 模块的user guide中的Dead-band sub-module的说明。

即下图，信号经过死区后，输出多种模式active high complementary, active low complementary, active high, acitve low等。
