Newbie question: driving leds

Hello again!

Ok, I found the design files. Sorry.

Yes, that's also what I did, I opened the cycloneIII_3c25_NiosII_standard file.

Beside this I'm sure the program works. The original program just says

"hello world", and the pdf tutorial sows the code to be added to blink one led.

I added the code, recompiled and could verify that the led blinks.

Now, replacing count & 0x01 by count & 0x0F and recompiling has no effect.

What I did is exactly what is explained in the tutorial for NIOS. So there is no

FPGA design. The FPGA design file (which is ready to use for this tutorial) is loaded

and then the program is compiled and run.

Now I checked the pin planner. Indeed, the led[1] is on T1. So I changed it to P12.

Now something I don't understand:

Why are there 2 nodes on the same pin ? I mean top_led and top_out_port_from_the_led_pio.

Thans,

Pascal

PS: Now it's late here, I will continue tomorrow.
