Can't reset PIO edge capture using IOWR_ALTERA_AVALON_PIO_EDGE_CAP

Dear experts, I am Nios beginner. I wonder why I cannot reset the edge capture register using IOWR_ALTERA_AVALON_PIO_EDGE_CAP (to reset it inside my ISR)? //after first interrupt...

That's incredible! The same code with the same error is generated by Nios II SBT for Eclipse in the count_binary sample, that writes:

IOWR_ALTERA_AVALON_PIO_EDGE_CAP (BUTTON_PIO_BASE,0);

writting '0' instead '1'... I was one day looking for the error and debugging the program before coming to these fora, when I finally found the solution.

Why the sample code is wrong?

Additionally, I have problems writting the display with the code generated by the system... I will look again in the forum to see if this is due again to errors in it...

Regards,

Antonio
