Yes, in my opinion this is exactly what this group is about: helping
each other while offering information and support to the area
community.<br>
<br>
Along these lines I'm thinking the upcoming meeting ought to double
back to a theme we've covered periodically, which is how to get off
square one with some of the common single board computer systems and
bare chip setups. We could think of this as an "install fest" where
by "install" we actually mean "getting my lights to blink on my
board X" and "lights" might be LEDs, a turning motor, sensor
samples, etc, and "board X" might be a standard Arduino, a Raspberry
Pi, Beagle Board, etc, or standalone chip scenario.<br>
<br>
Perhaps we could start with a series of lightning talks to
introduce/demonstrate one of the above combos/scenarios and then
after the lightning talks we could break up into sessions where
folks can get more demos and hands on opportunities relevant to
their needs.<br>

<div>Great, this is what I think I needed to know. So from what
you said I can just write my specific SPI code and not worry
about it interfering with the programmer when I'm uploading a
revised HEX file. I have noticed that programmers don't use
the SS pin which I will need for my own code. So if the
programmer never pulls down the SS pin then my code is not
going to see any action on the SPI bus. Why I didn't see this
before I don't now, but that why we have this group.</div>

<div bgcolor="#FFFFFF" text="#000000"> No sweat, Carl. I do
this very frequently, assuming we're talking about Atmel
chips. For programming purposes the reset line is yanked
in specific ways that invokes the chip's low level
programming protocol, while for SPI devices there is a
specific chip select line for each device that avoids
interference with either the programming scenario or some
other SPI peripheral.<span class="HOEnZb"><font

<div>Is it possible to use the SPI pins on a
mircorcontroller for two purposes? For example
used to burn the hex image and when not burning
the image then in normal running mode used to
control motor speed, etc. or something similar.
My guess is yes, but I haven't figured out how
to do it.</div>
