1  Using Arduino / Installation & Troubleshooting / IDE startup time on: November 11, 2013, 04:40:06 am
Hello,

the startup of my Arduino IDE 1.5.4 on OpenSuse needs about 16 seconds to come up.
Is this a normal time or is there a way to improve this ?

thank you for this info !
now it works smiley
3  Using Arduino / General Electronics / MCP3421 pinouts ? on: November 01, 2013, 02:13:08 am
Hello,

on my very little MCP3421 (SOT23-6) is no orientation mark or text visible.
Is there a way to find the pinouts with some simple measurements ?

Is there any working Arduino code available to drive this ADC ?

4  Using Arduino / Programming Questions / Re: output preprocessor variables on: September 21, 2013, 02:49:25 am
output as a Warning or whatever in the console area of the IDE when hit 'verify'.
I just want to see the variable contents during preprocessor runs.
5  Using Arduino / Programming Questions / output preprocessor variables on: September 21, 2013, 01:43:47 am
Hello,

how can i get the values hold in preprocessor variables ?
e.g.:
Code:
#if defined(ARDUINO) && ARDUINO >= 100
  #include "Arduino.h"
  #include "SoftwareSerial.h"
  SoftwareSerial port(12,13);
#else // Arduino 0022 - use modified NewSoftSerial
  #include "WProgram.h"
  #include "NewSoftSerial.h"
  NewSoftSerial port(12,13);
#endif

i want to output the content of "ARDUINO" during compilation

6  Using Arduino / Microcontrollers / Atmega32u4 Breakout and IDE1.5.4 on: September 19, 2013, 07:34:07 am
Hello,

i want to program an "Atmega32u4 Breakout Board+" using ArduinoIDE 1.5.4.
http://ladyada.net/products/atmega32u4breakout/
Is this possible out of the box ?
Is it generally possible ?
Where can i find infos to get it work ?

thanks for help

7  Using Arduino / Networking, Protocols, and Devices / Arduino as a GPIB Controller 2013 on: August 04, 2013, 01:35:33 am
Hello,

i wanted to add a post to this thread but seems to be closed (?)
http://forum.arduino.cc/index.php?topic=21821.0

I found this project and want to ask here, if anyone used this successfully.

https://github.com/tibal/agipibi

The author does not answer to emails and i did not find any more info
as this github page. I would like to see a session log or some other
examples how to use in detail. Any hint highly welcome,

8  Using Arduino / Programming Questions / Re: serialEvent() with the Esplora,Leo, Micro on: July 17, 2013, 03:02:18 pm
what does this mean : ?
NB : Currently, serialEvent() is not compatible with the Esplora, Leonardo, or Micro

AWOL,

for my understanding this skeleton does nothing except looping.

Let's say, i want to switch LED13 ON when something received on serial port.
10  Using Arduino / Programming Questions / Re: serialEvent() with the Esplora,Leo, Micro on: July 17, 2013, 02:43:10 pm
AWOL,

can you provide a complete sketch which demonstrates it, please ?
thx
11  Using Arduino / Programming Questions / Re: serialEvent() with the Esplora,Leo, Micro on: July 17, 2013, 02:38:42 am
Nick,

yes, sure, this is the polling approach but is not very efficient.
The event driven approach has also advantages dependent on task.
An answer is still highly welcome.

12  Using Arduino / Programming Questions / serialEvent() with the Esplora,Leo, Micro on: July 17, 2013, 01:27:13 am
Hello,

is this limitation just a question of patience and wait for implementation or is it a permanently hardware problem ?

yes, capital extension "S" did it smiley

Thank you very much for the explaination.

Still have problems, but i think it's a simple path problem:
Code:
> avr-gcc -mmcu=atmega328p -nostartfiles ./blink2.s
./blink2.s: Assembler messages:
./blink2.s:9: Error: constant value required
./blink2.s:13: Error: constant value required
./blink2.s:16: Error: constant value required

15  Using Arduino / Programming Questions / Assembler Blink example on: April 10, 2013, 01:06:07 am
Hello,

is there an assembler example (e.g. blink.s) with command line build and
upload instructions available for Duemilanove ?
I found the following code example, but do not really know how to use it.
Got errors when try to compile
> avr-as ./blink.s
and i do not have "delay_n_ms.h" 


 
Code:
; Assembly Code:

.include   "m328Pdef.inc"

start:     

         SBI      DDRB,5


blink:              LDI      r20,250
         CALL       delay_n_ms
         SBI      PORTB,5
         LDI      r20,250
         CALL       delay_n_ms
         CBI      PORTB,5
         JMP       blink

.include   "delay_n_ms.h"

thanks wally
