USB Article in Nuts & Volts

This months Nuts & Volts magazine (June 2006) has an article I wrote on using the PIC 2455 (or siblings) for simple device control.  Firmware and PC appliction is all open source (GPL), available through: http://www.nutsvolts.com/toc_Pages/jun06toc.htm
 
Firmware built using SDCC compiler.  PC application in C#, using Visual Studio (the free Express edition works).
 
Hopefully this will help folks that are just starting with PIC USB chips and want a simple circuit and software to make it go.  Demonstrates: turning LED on/off (gotta start somewhere), moving a servo, motor speed control, and firing a solenoid.

    Wow!  That's very cool!  Congrats on being published.
     
    How did this come about?  Did they contact you, or did you submit an article?

    Thank for the GPL'ed formware and software.
    Could you, if you have the rights, publish the text of your article, for those who can't buy Nuts & Volts magazine (other countries). Maybe at the end of the month, when the magazine stop being sold by press?

    I'm in Australia and recieve my "digital" subscription copy each month in my email, and it's cheap too!
     
    Magazines and authors require income to write this stuff so I guess credit (and cash) where credit (and cash) is due! Smile
     
    Cheers,

    Hi Xander,

    Where do you get the sdcc port for PIC18F2455 and some other PIC18 devices, as I can see from the original SDCC package at sdcc.sourceforge.net only support for limited PIC18 devices?

    Did you compile it on your own? Where do you get the header and library? Is is possible to create the header and library for other PIC16 or PIC18 devices?

    Thank you,

    soliton

    Try the snapshot but I think I had problems to compile the code.

    Soliton,

    Sorry for delay, holiday & vacation...

    Nuts & Volts is supposed to be posting a version of SDCC & GPUtils along with the source for the article.  I'd post here, but am limited to 200K (the sdcc.exe alone is over 1.4M when compressed).
     
    For source code for GPUtils & SDCC, you can go to SourceForge.  Until SDCC has another public release, the nightly builds (or source tarballs) are the only way to go.

    Xander
