I graduated college about 3 years ago as a computer engineer. I have not worked on fpga board since then where I used a Sparten 3 board. I just order a Nexys-2 (Spartan 3e) to do some home projects. I am new to ucLinux but use linux. I think I will be able to setup the board following the instructions from petalinux.
However, I am unable to find how to send PWM signals out. The PWM signal will go through a NPN transitor and then drive a piece of biometal helix.
How would I measure the resistance of the biometal wire that is changing. Is there some kind of external device that I need to output a signal back to the fpga board or can the fpga handle this directly. How/which device in the /dev folder would I access the input.
Also there are some nice example programs in the petalinux distribution like gpio_test.c but I was wondering if there are some more simple examples like the ones from petalinux out there.
What is the best way to figure out what each device can do in the /dev folder and how to use them?
