Does anyone have a copy of these?
Thanks, Ian

First post, there is a zip file
No there isn't. They're all dead links.

thanks for the reply.

Adafruit has developed libraries for the printer, these libraries are just wrappers for Comand Esc / Pos
( ... al/A2-user% 20manual-1.pdf)
So it is not important to the wrapper code, but the commands Esc \ Pos I have to send through a sequence of bytes, which should allow you to align the bitmap.
thanks anyway.
Is it Esc / Pos or Esc \ Pos? Maybe that's where your problems are.

Is this a microwave oven? Can you give details of the make and model? And perhaps a diagram of the wiring you are referring to?

If it is a microwave oven, I'd tell him to steer well clear of any idea of playing with it, unless he want's his brain cooked.

For the project, the wire has to be able to be strung through very small holes by the user and then connected to the actual board/dip/connector.
I've looked all over and there don't seem to be any out there. That I can find anyways, which lead me to ask here.
Would a ZIF socket work with your thin wire? I don't know how small you can get them.

In the "old days", one would use a uniselector.  The original multiplexer.
I've one of them somewhere in my attic. Old PO telephones Strowger gear that worked on 48V DC.

How come for digital pins, the pin has to be initialized in the SetUp()? Ex. pinMode(13, INPUT) or Ex. pinMode(7, OUTPUT)
But for Analog pins, you don't have to write a command to tell the Arduino whether or not you are reading or writing on the analog pin in SetUp()? In fact, you dont have to even mention the Anolog pins in the set up at all and can simply call Analog functions such as analogRead() at will in your loop functions.
I was just curious as to why this was.
The analog pins are only analog inputs, so there's no need to declare them as such. They can't be used as analog outputs. They can be used as digital pins, when they have to be declared as either an input or an output, exactly as the other digital pins are. The only "analog" outputs are the PWM pins. They can output a 5V square wave with a variable mark - space ratio, which is a pseudo analog output.

wish list item smiley-wink

Connects e.g.  sensors to a phone over the speaker connector. Imagine a shield that does the same..
If it does SPI, you won't need a shield.

Just ignore them if you find yourself wasting time on unprepared minds. Maybe a later time the same person comes better prepared, or just disappear.
A killfile/bozo bin would be useful for that.

Now i see. I didn't scroll down.  Sorry bout that.  That's starting to make sense. 
If I spend my time writing code that does what you want and you don't even look at it, I think I'm wasting my time with you. Goodbye!

But, unless you're on your hands and knees, you'll only see the cables.
I cant attach it under the table either. Too visible there. I mean this table is in living room smiley-razz
But it will be easily removable. Just slide it into place, like attaching a flash gun to a camera. When not in use, just slide it out of the hanger and put it away. The hanger will be about 3mm below the underside of the table and invisible to anyone standing nearby, when not in use.

Go to Halfords. Buy a can of spray paint that matches your d├ęcor and spray the PSU's case!
131  Using Arduino / Project Guidance / Re: Detecting common interests in a meeting on: June 03, 2014, 03:52:30 pm
In a crowded room, there is the likelihood of several 'couples' matching at the same time, for different interests. The only way to tell if the person next to you is flashing because he has your interest, and not someone else's interest, is to ask them. This negates the purpose of the badge. Why not just ask people what their interests are, without using the badge?
If you've only 3 different interests, you can 'draw' a Venn diagram on the floor and get people to sit or stand in the area that matches their interests. You can use 3 different (primary) coloured spotlights for this.
132  Using Arduino / Project Guidance / Re: What heating? on: June 03, 2014, 03:01:33 pm
How about a heat exchanger. Pass hot water slowly through a coil inside the box. If the water is 50o at the input and 50o at the output, then the inside of your box will be at 50o. The inside of your box will never be hotter than the water temperature.

Hmmm I've been digging a basement under my house for years ... Didn't find any elves....... I probably live on the wrong place..........Should I move??????

You haven't dug deep enough...   smiley
134  Community / Bar Sport / Re: How do you say? on: June 02, 2014, 11:48:21 pm
Yep. I spent 30 minutes writing a piece of code for someone, to do exactly what they wanted. I got back "Very nice, but how do I do what I wanted?" Duh!   smiley-yell 
Maybe there could be a special flag to denote postings by morons, so that we can avoid them?
I've got it!
A sticky with stepwise instructions of how to wrap up their Arduino and post it back to the supplier.   smiley smiley

There is no such thing as a stupid question but there are a lot of inquisitive idiots.
There are??   smiley
