KD8CEC's Memory Keyer for HAM
|
|
|
|
This source code is written for All amateur radio operator,
|
|
I have not had amateur radio communication for a long time. CW has been
|
|
around for a long time, and I do not know what kind of keyer and keying
|
|
software is fashionable. So I implemented the functions I need mainly.
|
|
|
|
To minimize the use of memory space, we used bitwise operations.
|
|
For the alphabet, I put Morsecode in 1 byte. The front 4Bit is the length
|
|
and the 4Bit is the Morse code. Because the number is fixed in length,
|
|
there is no separate length information. The 5Bit on the right side is
|
|
the Morse code.
|
|
|
|
I wrote this code myself, so there is no license restriction.
|
|
So this code allows anyone to write with confidence.
|
|
But keep it as long as the original author of the code.
|
