</div>Ah, nice. Suspected it was the case but asked to be sure.<br>

</div>And a very nice platform for experimenting with multi-touch panel<br>
readings and boundaries.<br>
<div class="HOEnZb"><div class="h5"><br></div></div></blockquote><div><br>yes! you wouldn't believe the cost i've found (10k volumes). a company in HK, recommended off of ST's web site, they are doing such high volumes that even the 100-pin STM32F106RVT6 is just under $2.50. stunning. they sell in lots of i think it's 850, they come in packs, they just ship them straight out, no splitting packs, nothing.<br>
<br>it's... mad. absolutely mad. _so_ no need for any of these 8052-based ICs, one for camera, one for audio, one for this, one for that. i had absolutely no idea that there were so many processors in a single tablet. adding it up, there must be what... *eight* separate processors, even as many as 10 or 11 if it's got 3G and GPS.<br>
