Hi folks
I am trying to learn some c/c++ programming and I thought I would like to
try some different algorithms for CW recoding (weighted averaging etc)
what routines can I use to do the following:
a)
time the key-down period of (eg) the space bar so that I can test the
code using the keyboard for input.
b)
use the sound card to measure the length of time a single tone is heard.
This measurement would then be used to determine dit-length etc
Thanx for any pointers, references etc you can give me.
cheers 73 de VK6PEC
