This is the third or fourth in this series. I paused for a while and just picked it back up again. As I eat my soup and write this, it occurs to me that I've given each post a different name so if anyone actually wants to follow my progress, I've made it quite difficult to do so. I'll recap first and then later, try to be more consistent with post titles.
- It all started at the ESC show back in Boston with this post called "Easy Zigbee" about some ZigBee modules I found in the Microchip booth. You'll note that I'm using Microchip components in this series, but my sister company, MEC Innovation, uses a lot of Atmel chips. We like both company's chips here. Especially with good salsa.
- Next, I wrote about my plan in "ZigBee, Part two".
- The most recent post in this series was "PCB123 QFN Footprint". That's where I started with the CAD package and I got stalled with the parts library.
From now on, I'll identify this series as "PCB123 ZigBee Robots, Part X".
Anyway, enough of that rubbish. I've picked it up again and this morning created the library part for the QFN28 PIC18F2321 microcontroller. I'm lousy at building footprints so I consider that a major accomplishment.
I have a couple more footprints to make - a DFN8 regulator and a CSP BGA RS232 chip. I muddled through the microcontroller but after I do those other two chips, I should be clear enough to able to post some hints on how to make your library components in PCB123.
Later - I'm going to finish my soup now.
