Hi All,
I intend to start a project that uses a LCD display (2x16, parallel data
input), three switches for input, three digital outputs, that each generates
a pulse with a specific width. 
Pulse2 and pulse3 come after delay2 and delay3. I want to modify the delays
from 1us to 200us, with a resolution of 1us, as well as the widths of
pulse1, pulse2, pulse3.
For this operation, I think using three switches, as: "Select Next
Parameter/Set Value", "Up", "Down".

Now, I can use assembler or C (limited size code). I have limited experience
with both in the microcontrollers world and if possible, I prefer C. I don't
mind combining them two, if necessary.

I would like somebody with more experience than me to advise about the
structure of the program.
Should I use interrupts, timers, etc? How should I deal with the LCD? I only
need the LCD to view and set the parameters, so the LCD could come to life
only when I press on the "Select Next Parameter" Key.
The values set for pulse widths and delays should be stored into the EEprom.
In the past I tried using some libraries of "precise delays" in C, but the
delays I obtained were nowhere what I expected. I will give it another try
anyway.

Any advice appreciated.

Regards,
Nick
