hallo
meine wetterstation sammelt laufend Daten die auf einer SDkarte gespeichert werden.
Nun möchte ich die Datei periodisch via FTP auf meinen Rechner pushen.
Auslösen will ich das nicht mit einem Taster sondern mit einer IR-Fernbedienung.
Ich habe nun einen Versuchsaufbau gemacht, der aus einem Duemillanove, einem Ethernet shield und dem IR-Empfänger (Typ 1883) besteht.
Dazu hab ich zwei Programme, den FTP-Client und die IR-Steuerung separat ausgetestet und die tun was sie sollen ...

FTP: bei Eingabe von "f" wird die Datei "test.txt" von der SDkarte auf den FTPserver geschickt. (mit "r" wird sie auf dem Serial Monitor gedumpt)

/* CHANGED 20141225
for IR Car-mp3 remote control
shows only pressed button

RGB Remote Control
by: Jim Lindblom
SparkFun Electronics
date: October 1, 2013

This sketch uses Ken Shirriff's *awesome* IRremote library:
https://github.com/shirriff/Arduino-IRremote

RGB Remote Control uses a combination of SparkFun's
IR Remote (https://www.sparkfun.com/products/11759) and an
IR receiver diode (https://www.sparkfun.com/products/10266) to
control an RGB LED.

The IR Remote's power button turns the LED on or off. The A, B,
and C buttons select a channel (red, green, or blue). The up
and down arrows increment or decrement the LED brightness on that channel.
The left and right arrows turn a channel to min or max, and
circle set it to the middle.

Hardware setup:
* The output of an IR Receiver Diode (38 kHz demodulating
version) should be connected to the Arduino's pin 11.
* The IR Receiver diode should also be powered off the
Arduino's 5V and GND rails.
* A common cathode RGB LED is connected to Arduino's pins
5, 9, and 6 (red, green, and blue pins).

// pin 6 : as 2

// pin 10 could not be used; reserved for SDselect
// pin 11 : original setup nothing works; neither keyboard nor IRremote (SD open fail) <------------------ !!!
// pin 12 : only 'r' works, but displays unrecognized code at the end
// ----------------------------------------------------------------------------

code snippet (ganzer code ist am Ende angehängt!!)


...
case BUTTON_32:
Serial.println("+");
Serial.println("Uebermittlung startet ...");
if(doFTP()) Serial.println(F("FTP OK"));
else Serial.println(F("FTP FAIL"));

...

von "+" geht's zur FTP routine, die als erstes die SD karte lesen möchte
fh = SD.open(fileName,FILE_READ);
aber genau dasselbe passiert in der read&display-routine ... :mad::mad::mad:
und dort funktionierts


hier noch der SerialMonitor für IR an PIN_11 resp an PIN_2 (alle Ergebnisse: siehe oben)
-----------------------------------------------------------------------------
PIN_11:
Ready. press 'f' or 'r' on keyboard or with IRremote use CH , + for transmit
CH
Bitte FTPserver starten und + druecken zum Start der Uebermittlung...
+
Uebermittlung startet ...
SD open fail
FTP FAIL


PIN_2:
Ready. press 'f' or 'r' on keyboard or with IRremote use CH , + for transmit
CH
Bitte FTPserver starten und + druecken zum Start der Uebermittlung...
+
Uebermittlung startet ...
SD open fail
FTP FAIL

nun die "5" auf der IR gedrückt
5
Lorem ipsum dolor sit amet, ...

nun dasselbe durch Eingabe von "f"
Ready. press 'f' or 'r' on keyboard or with IRremote use CH , + for transmit
SD open fail
FTP FAIL

und nun von "r"
Lorem ipsum dolor sit amet, conset
-----------------------------------------------------------------------------

leider bin ich nicht in der Lage die libraries zu analysieren (oder ist der Fehler im code?) und hoffe auf hilfe aus der community
vielen dank und en guete rutsch iis 2015 ...
