Brad Ormand - ARM 0.5mm pin pitch soldered and tested

11.22.2014 – Potluck & ARM Cortex

The day before yesterday was a social day.  I made Pico de Gallo from scratch for a Potluck I went to.  And, the conversations were flowing.  We talked about all kinds of stuff and ate, and, went back for more.  It was with a lot of people from work, and it was great to be able to just chill out and talk about our personal stuff for a while.  So, lots going on that day.  Didn’t work on projects much that day, but had a lot of needed social fun.

The Pico de Gallo was amazing and I want to make it again for Thanksgiving, if possible.  And, it was fun to make.  I have a slight tweak in the recipe that I want to try.  I guess I treat cooking creation just like I would do any other project.  Iteratively refining.  🙂

And in other news, I did end up soldering that ARM chip in juuust fine.  Oh my god, though – it was a big challenge!  Yeah, please excuse my amazement if you are a veteran eyelash-pin-pitch solderer, but I had a bit of trouble starting up.  I had never gone *that* small before!

Ok, enough of the drama…  I did it.  It’s done.  I checked the continuity of every inner lead and outer lead (board connectors) individually, and it’s fine 🙂  I’m getting the development  toolchain ready to go, and I’ll be on my way to (finally) doing some more coding again, and to hop back on that FFT testing with my wonderful array of displays.  Love it!

So, it’ll take me a few days to get all of this going.  Also, there are a lot of port names I have to learn, and the pinout of the chip has to be mapped to JTAG and so on.  I have to do the ground work.  Yeah, I could buy a ready-made development board, but nah – that’s not what I’m doing this game for.  I want to learn how to build around a chip in my projects.  There’s a chip – it’s pinouts are like this, and its inputs require filtering and it gets x-and-x regulated power and outputs to this other stage that I need to amplify, etc, etc.  That’s the fun part. 🙂  And, plus, I have specific space-sensitive applications for this development and I want to make applications that actually embed tightly in cases…  So, the getting used to devving with the dev boards is convenient, and you don’t have to (or maybe don’t *get* to) reinforce those skills and practicalities of like soldering the chip, pinning out the JTAG, etc, but that’s where the product space is at.

Anyway, so that’s the direction I want to keep going in.
