i use the interrupt with the button pio like that:

# include <cyg/hal/io.h> // for iowr and iord

unsigned char ledpio;

cyg_interrupt int_pio;

cyg_handle_t int_pio_handle;

:

<div align='right'><{post_snapback}> (index.php?act=findpost&pid=12562)

Thank you, All.

Especially GLecordier, thank you for showing your code.

Now I can use interrupt as I expect.

The reasons are

(1) I tried to use printf in ISR.

(2) I didn&#39;t unmask the interrupt.

Thank you, very much.
