[Elecraft] W1 Programming???

[kevinr]

I just wrote a little code using Posix standards under Ubuntu with g++ 
for my compiler.  Looks like USB is treated as a normal stream of 
characters.  The most difficult part was finding my USB thumb drive in 
the file system.  Under Ubuntu it is in the /media folder.  Once I 
located it I was able to read from it, and write to it, using 
straightforward code.  The W1 wattmeter should react the same way.  
Write a trap to catch the data packet then a little code to parse it 
however you like.  I did not know it would be so simple: open(), read(), 
write(), close().

Since Macs are running Linux, with enhancements, writing code to catch 
the wattmeter's data stream should not be difficult.  I assume you can 
send it commands too.  You will need to determine how a data packet is 
formed but that is part of the fun.

    73 and GL,

I use a Mac and a Raspberry Pi and do not have VB on either, nor do I want to. I’m fairly proficient in several other programming languages and am thinking that I might “roll my own”, starting on the Mac.
