<font face="Arial">Since eBay and other places are currently flooded
with STM32 evaluation/demo boards in the $2-$3 range I figured I'd
look into them for quick projects where I'm not doing a dedicated
PC board.<br>
<br>
Well, aside from a small pain getting started programming them
bare metal (their documentation could be better) I got a
surprise...the STM32F0xx and STM32F1xx lines do NOT have
comparators. They have 12 bit AD converters and they have digital
comparators on the output of the converter (what, you can't
compare numbers in software?) but no voltage comparators. Odd
since that's so simple once you have the AD hardware.<br>
<br>
Well *grump*. Have to hang a comparator chip off the board, means
a trip into the "junk box".<br>
<br>
Wish I could still get the Zero boards with NXP processors, they
were nice and low cost.<br>
