Windows Installers - Having it your way.

Despite being my blog about "software and electronics", I've been sparse on posts about what's historically been my bread and butter - the Windows Desktop platform, still the best thing to happen to computing since sliced bread ... and butter. It's just not as sexy as the exotic embedded stuff or the mobile platform du jour.

Aynways I've been meaning to compile and post a list of windows tools that I think rock. I'm always surprised when I find out someone whos been using windows for a long time doesn't knwo about some particular tool I've been using forever and think is essential, "what, you mean you've never heard of SciTE?".

7-zip is definitely a tool in that category. It can open just about anything considered an "archive" format, zip, gzip, tar, rar, iso, and one that I find handy when something's gone wrong: msi and cabs.

I recently got my atmel cpld JTAG programmer, and wanted to install the AtmelISP software. For some reason only known to my PC, the installer refused to complete, and performed a lat minute cancel/rollback at the end of the install.

While the fail dialog was up, I used Sysinterals procmon (another rockin tool, by the way) to find out the installer wrote some temp files that happened to be "msi" (Microsoft installer packages). I copied the msi files and opened with 7zip, which allowed me to extract the atmel isp software. This worked in this case becasue there were no critical scripts run by the installer other that to install ftdi drivers, which I already had installed.

ATDH1150USB mini tear down.

Last month I mentioned the ATDH1150USB Atmel CPLD JTAG programmer, and my efforts to home-brew my own programmer based on some ancient code I found on Atmel's website.

The escalating level of effort required to make my own programmer outweighed the $45 it cost to just buy the Atmel programmer. Slightly annoying, since I already own an Atmel branded JTAG device, the AVR Dragon.

There's scant information on the web about the 1150, unlike it's popular Altera cousin the "USB Blaster".

Here's the hardware that came in the box:

Box contents: mini USB cable, a loooong (I estimate 18") 2x5 JTAG ribbon cable,
and a 6" 'JTAG-X" 

The first thing I did was immediately void my warranty(does this thing even have one? I have no idea, I'm guessing that the folks at Atmel would be laid back if I ever ran into issues, this isn't a consumer device. )

CPLDs, and the importance of knowing when to quit.

As an engineer, I can have a natural tendency to become obsessed with problem solving. Every problem I come across is a personal test, "If this problem is solvable, I will be victorious, I will conquer it". I think the hard thing can be recognizing when the solution isn't worth the effort. The ability to spot this before others is what can make a great manager, that's not what this post is about, however.

Let me tell you a little story about CPLD's:

Now if you ask my wife, she'll tell you I'm the cheapest, stingiest man alive, if you ask my mother, well she'd probably agree, but if you asked me, I'd tell you I just take pride in being resourceful. I've always had a hard time paying someone to do something I could easily do myself.
