pwm中断

如图：

是有什么用的。

你要做什么

我想做一个spwm 初步想法是如果pwm每发生一个波形后触发中断改变一次占空比不知道是否可行

还有pwm他的中断是否就是每产生一次波形触发一次中断？

Interrupts
The Interrupts parameters allow you to configure the initial interrupt sources. These values are
ORed with any of the other Interrupt parameters to give a final group of events that can trigger
an interrupt. The software can re-configure this mode at any time as long as Interrupts were not
set to "None"; this parameter simply defines an initial configuration.
• None – No interrupts are set.
• Interrupt On Terminal Count Event –This option is always available; it is set to "false" by
default.
• Interrupt On Compare 1 Event – This option is set to "false" by default. It is always
shown.
• Interrupt On Compare 2 Event – This option is set to "false" by default. It is only
available when "UDB" is selected for Implementation and PWM Mode is set
appropriately.
• Interrupt On Kill Event – This option is set to "false" by default. It is only available when
"UDB" is selected for Implementation and PWM Mode is set appropriately.

pwm每发生一个波形后触发中断改变一次占空比 - 可行
还有pwm他的中断是否就是每产生一次波形触发一次中断？- 可以设置

谢谢了。不知道哪里可以找到中文文档。。对于上述问题，我已经解决了，用的是pwm中断后修改占空比实现了spwm波

你是说用户模块的是吗？打开其网页如PSoC Creator组件数据手册或PSoC Designer用户模块数据手册在后面的language里面选择中文就可以了，器件的datasheet也是一样

你说的可靠是指什么？你试验验证一下就知道了

这个中断是输入还是输出呢？

发表于 2012-7-21 17:44

是输出，用来产生一个中断信号，告诉CPU中断当前的执行，进入中断服务程序中要求执行的动作。

OK ，哈哈

那就先结贴了
