Try running two simultaneous instances of Arduino.

32  Using Arduino / Displays / Error with compile with 3.23"LCD/touchscreen on: June 10, 2013, 12:42:56 pm
I bought a LCD/touchscreen off ebay. The software provided only addresses the LCD, and works. I found a touchscreen example on the web,but it is an ino file and will compile but I have the wrong version of the board for the LCD portion and it wont work. I renamed as a pde file and changed it to use WProgram.h instead of Arduino.h. It gives one error on line 24, " ITDB32S was not declared in this scope". I searched Arduino.h but it is never declared there. I have no idea where it is declared, or what type it is. Sinceyou need the special liubrarys I put the wqhole thing up on my

I always liked the definition I was given by my high school calculus teacher!

A specialist learns more and more about less and less until he knows everything about nothing. A generalist learns less and less about more and more until he knows nothing about everything.

Thanks to both Nick and John. After seeing the schematic, I OHMed it out. Your both absolutely right!

35  Using Arduino / Project Guidance / Help with RTC on: February 25, 2013, 03:40:41 pm
Some time ago I bought this

After testing it, I put it in my parts bin for a planned project that never happened. Now I am thinking using it with my Raspberry Pi. It seems straight forward except for the pin labeled DS. I combed the net for a schematic with no result. I'm hoping you experts can shed some light on this.

Hopefully Jim

I working on a project where I need some (10, male pc  mount) of those 3pin connectors used to connect sensor "bricks" to shields. Does anyone know what part numbers they are and maybe a good supplier?

I recently got a Google Nexus 10. What a sweet machine! It has a beautiful screen. My youngest daughter said she wished she had one instead of her "fondlepad" (iPad), and she is so Apple she probably has the company logo on her unmentionables.

I have a project that needs a touchscreen. There are two on Ebay with very different prices. I wondering why.


39  Community / Bar Sport / Re: Where did you start with Micro controllers? on: December 26, 2012, 08:46:02 pm
In 1966 the company I worked( aerospace ) designed a package with a Rolm computer.The Rolm was a militarized Data General. I worked in the Calibration Lab and was sent to a school to learn to maintain the beasts. They had 4K of core memory and you load a bootstrap loader by hand and then loaded a tape with the system from the tape reader on a teletype. In class they would start the load and give a lecture while the teletype clunked on and on.

I havn't been to a Radioshack in probably 5 years. Last time I went in there I said I was looking for a BNC connector and the guy behind the register looked at me like I had two heads. Might have to stop by again.

That is strange, I live in a town of 2000 at 8000 ft in Colorado, and the RS is part of a fishing/hunting/tourist trap/Verison store. Every time I go in for some oddball part, the clerk goes right to it.

Man I remember getting a 4004 data sheet as a promo, I read it and couldn't for the life of me see how these microprocessors things could be useful for anything.

Wrong smiley

Still at least I didn't put all my money into buggy-whip shares.


That's nothing. I met the two Steve guys, Jobs and the Woz, in the mid 70s up in Rohnert Park. They were travelling around the Bay Area trying to sell/raise interest in their original Apple (1) populated PCB. They showed if off mounted is a homemade wood box, and a user had to supply their own keyboard and TV monitor. I looked it over and said this thing/these guys are going no where! Talking to him, I thought Woz was a real nice guy, a real nerd/hacker from the old school, but Jobs was even then was looking for something that would 'show me the money', that came through pretty clearly even back then.


I was at the Homebrew Computer Club meeting where the Steves first showed the Apple II. I worked at Stanford Linear Accelerator Center and the meetings were in our auditorium. I had an Altair. Those were heady days!!

42  Using Arduino / Networking, Protocols, and Devices / Need help understanding html forms on: October 20, 2012, 04:50:11 pm
I am trying to switch things (currently a led) from a web page. Thanks to zoomkat, I am well along. I could switch the led on/off with a ext field, now I am trying radio buttons. There are two problems
1) you seem to be able to have two buttons clicked at once
2) nothing gets back to the server
I am creating the buttons thusly
          client.write("<form>Led Off <input type=radio name=t value=Led Off>");
          client.write("Led On <input type=radio name=r value=Led On></form>");
The ino is much too big so I am attaching it as a zip

So, your problem, despite the thread title, has nothing to do with ethernet. Right?

Still, the behavior is not normal. You'll have to remove the randomness. That is, you'll need to determine what the pattern is. What other serial devices do you have? Are you running any kind of bluetooth software? Something that tries to connect to all the serial ports to see if there are bluetooth devices connected?
I have experienced this problem with the webserver, webclient, telnet client in the examples with the ethernet library, also with SDwebbrowse.ino from the Adafruit site. I have a Windows 7 PC, Arduino 1.0.1 IDE, Mega, Ethernet shield and a LCD. It happens both with and without the LCD attached and with and without the LCD required libraries. When the Ethernet shield is not attached it does not happen. The program I'm working now is an extension of the SDwebbrowse program. I can add something as insignificant as lcd.print statement, go to reload and it happens. I save the program, reboot and reload the program, it will recompile and download correctly. The attached libraries are:
#include <SPI.h>
#include <Ethernet.h>
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#include <SdFat.h>
#include <SdFatUtil.h>

Is this normal?

If you showed the code, and explained what "the message area" means, and what "the download symbol" you are talking about is, perhaps a longer version of "no" could be posted, instead.

Code has varied wildly as i run different examples. Message bar is the blue bar at the bottom which says "compiling" and then "downloading", just above the area where errors are displayed. The download symbol is the round symbol at top right that turns orange when you click it and starts the download process, just below the menu bar. Now you can post "no"!

I have the line            if(strncmp(pch,"=1",1) == 0)                in my code. pch is "Chapter 1, page 23". As I understand the if should return a 0.  It doesn't,why?
