Pull-up On I/o Pin

Question

Bye everyone,

I'm a beginner on Altera software development tool.

Can you show me the procedure to set a pull-up on I/O pin,

on the documentation i found:

"In the Assignment Editor, set the weak pull-up assignment to ON to enable the on-chip pull-up resistor for the pin."

but it isn't usefull for me.

I'm working with a device of CycloneII, EP2C8F256C7 and Quartus II 8.0sp1 as development tool.

Tanks in advance, i'm looking forward for your answer.

Bye

Giordano

Why, did you try? The procedure generally works.

You also can enable weak pull-ups in Pin Planner, after showing the respective column through customize menu.
