<Shameless self promotion>

We have designed a very cool expandable display based on Arduino.  The ClockTHREEjr (8x16 mono) boards can be stacked side-by-side to make long LED displays, each one can display two 6" characters.  Please have a look at or just launched KickStarter project.  We need $2500 to purchase the min quantity of kits.

3  Using Arduino / Installation & Troubleshooting / Re: pre-compiler directive not functioning as expected on: January 15, 2012, 12:27:22 pm
MarkT,

Indeed you are correct.  I should have simplified my example to the bare essentials.  I see now that the Arduino envirnment is ignoring the pre-compiler directives and thus tries to find "NewSoftSerial.h".  I was wondering what the standard work-around is to maintain backward compatibility.

Justin

Code:
// Arduino 1.0 compatibility
#if defined(ARDUINO) && ARDUINO >= 100
#include "SoftwareSerial.h"
#else
#include "NewSoftSerial.h"
#endif

Mark,

The code snippet is from the Arduino .pde file.

5  Using Arduino / Installation & Troubleshooting / pre-compiler directive not functioning as expected on: January 14, 2012, 11:03:58 am
I am migrating to Arduino 1.0 and am having issues with maintaining backward compatibility.
The following code does not compile on Arduino 1.0 unless the "#include NewSoftSerial.h" is commented out, even though this part of the code should have already been skipped by the pre-compiler.

Any workaround that that will allow me to compile in both Arduino 1.0 and older versions without modifying the source will be most welcome!

Thanks!

Code:
// Arduino 1.0 compatibility
#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"
#define WIRE_READ Wire.read();
#include "SoftwareSerial.h"
#else
#include "WProgram.h"
#define WIRE_READ Wire.receive()
#include "NewSoftSerial.h"
#endif

Here is the compiler message that goes away when the NewSoftSerial line is commented out with //
Code:
/home/justin/Documents/Arduino/clockthree/libraries/NewSoftSerial/NewSoftSerial.cpp:39:24: fatal error: WConstants.h: No such file or directory
compilation terminated.

Nice catch @Rugged!  I was able to recover the basic MEGA function but not the SD function.  I guess I've burned out the LS125A.

I also had a chance to look up your Yellow Jacket Wifi 'diono.  Very cool and great price. 

Thanks again for the help.

Thanks @Rugged!  I will look into this.  It looks like you've pinpointed the problem.  I'll let you know.


Thanks again!

MMCP42,

Not sure if this will help, but this is the code that was running fine before the failure.

Thanks,
Justin

Code:
void setup(){
  pinMode(2, OUTPUT);
  pinMode(3, OUTPUT);
}
void loop(){
  digitalWrite(3, LOW);
  digitalWrite(2, HIGH);
  delay(1000);
  digitalWrite(3, HIGH);
  digitalWrite(2, LOW);
  delay(1000);

}

Wow, you people are fast.  Thanks for helping me!

Sorry, but I uploaded the wrong version.  I've uploaded the current version here:

Well submit code in next post.

Thanks again!

12  Development / Other Hardware Development / ATMEGA328 TQFP Issue? on: July 04, 2011, 01:04:43 pm
We are building up an Arduino compatible with the ATMEGA328 in the TQFP package for the first time.  Now we have built two two prototypes and they both seem to be experiencing the same failure.  They both worked well to start with.  They accepted the boot loader and could be programmed from an FTDI cable.  The SD card interface even worked.

Then, after about an hour of running a version of blink (alternating two leds), one LED starts blinking rapidly.  It is like it is being reset very quickly. 

I can still upload programs via the ISP interface and can swap the initial LED in which case that is the LED that blinks rapidly.  I can reinstall the bootloader, but no longer will it accept programs from the FTDI interface.

We have built several boards in using the DIP version of the ATMEGA328 and just copied the schematic for this design.  Has anyone else experienced issued using the TQFP?

I have uploaded the schematic, and provided a link below.

Thanks,
Justin

Use I2C (also known as TWI) available thought the Wire.h.  Use one master ardiuno to connect to the PC via the usb cable.

FlorinC has gotten large font to work on the open Source WiseClock3.  Use his code as a reference.
