Other Parts Discussed in Thread: OMAP3530

hi,
I know that the omap3530 have 6 GPIO module. and in my design, I want connect 4 extern INT to omap3530 GPIO pin. Can I use the 4 pins in the same GPIO module? such as GPIO10,GPIO11,GPIO12,GPIO14, all of those pins in the GPIO module 1. whether any of the pin is changed, the GPIO module 1 interrupt request will to the MPU or DSP?

Chen,

You can use all these pins depending on your hardware requirements and muxing. Each GPIO interrupt will be treated as separate interrupts by the GPIO interrupt handler in the operating system. Are you using Linux?

Renjith,

Thank you for your reply.

Yes, i am using Linux.

Youlin,

Linux will treat the GPIOs as separate interrupts,so you don't have to worry on how to handle different use cases. Can you mark this post as answered, I you think so?
