Apologies if this has been covered before - a quick search drew a blank.
Here's what I'm trying to achieve:
A simple breakout board for a TLC5947. I have a pair working great on a breadboard, and now need to upscale to lots of them, each on it's own board. On the basis of me having to do the soldering, it would be the HTSSOP-32 package, rather than the QFN.
Also on the board will be two caps and a resistor. That's pretty much all you need for basic 5947 operation. (Surprisingly, none of the public domain board designs that I've found so far has placement for those bare bones components - hence wanting to do my own)
Signals will manifest either as big row of pads at the edge, or also be drilled and have 0.1" headers in them.
All of this is doable in two layers (possible even just one!).
Two issues so far:
1. The UI on the two packages I've tried (Eagle first, then Sunstone) leaves a bit to be desired. Are they all fairly arcane, or is there one out there that's a bit more intuitive than the rest? If they're all a bit odd, I'll just have to plough through the tutorials I guess.
2. Do any of them have a TLC5947 already in their library? I tried fashioning my own in Sunstone, but after a promising start it started telling me I couldn't save it. Or if they don't have a TLC5947, at least an HTSSOP32 generic.
Feeling *very* frustrated at the moment. Perhaps I just need to suck up doing the tutorials - if everyone else can learn Eagle, maybe I should too.

[update: I realised I'd not tried DipTrace... just fired it up and first impressions are good. No TLC5947 in the TI library, but I'll have a crack at creating one in the component editor.]
