<DIV>Hey Jeff, Thanks</DIV>
<DIV> </DIV>
<DIV>Thinking on PWMing motors</DIV>
<DIV> </DIV>
<DIV>I guess my tiny13 won't be driving the beasties.</DIV>
<DIV>Maybe Tiny26 -- Dale mentioned that part drives 40 mA per pin - so I looked
it up</DIV>
<DIV>200 mA for total part -- so reasonable. So I assume could tie 3
pins and pretty much drive motor.</DIV>
<DIV> </DIV>
<DIV>Of course would lose out on direct PWM output, but PWM gen can generate
soft interrupts which could </DIV>
<DIV>be used to twiddle bits on multiple pins.</DIV>
<DIV> </DIV>
<DIV>Tiny26 will run at 3 volts -- could always current limit motors just a tad
with series resistance.</DIV>
<DIV>I assume motors would not kill Tiny's pins with flyback spikes. Oh well, $2
down the drain if they do.</DIV>
<DIV> </DIV>
<DIV>I really like the idea of not having to involve an h-bridge or driver
transistors/fets -- too much complexity</DIV>
<DIV> </DIV>
<DIV>I know connecting 24 volts to an AVR pin will blow it.</DIV>
<DIV>Did get away with driving one on a Mega128 to almost dead short (8 ohm
speaker) for some time and it survived. The chip was running real hot -- then I
discovered a series resistor was shorted.</DIV>
