Pi Webserver Probleme, Hilfe! (Heimnetz) - Raspberry Pi Forums

guten tag, ich habe ein kleines problem. ich besitze seit kurzer zeit einen pi2 und kenne mich nur wenig mit rasbian aus. nun habe ich auf meinem rasberry einen webserver laufen, der schon mehrere tage ohne probleme läuft. doch nun bekomme ich in meinem eigenem heimnetz, egal welche url ich eingebe, nur die seite des pi´s die mir sagt das diese html datei nicht auf dem pi zu finden ist. hier eine dieser meldungen: not found requested url /de/x not found on server. apache/2.2.22 (debian) server @ x.org port 80 hat jemand eine idee wie ich das heimnetz wieder hin bekomme? rückfragen einfach in die antworten schreiben. mfg maxilo311 ps: ich habe 2 wlan netze vom gleichem router. das wlan indem der router ist funktioniert ohne probleme, es handelt sich um das 2. wlan. maxilo311.de raspberrypi

Como usar uma função

olá! por favor, alguém pode me dizer qual é maneira correta de chamar uma "friend class"  no código? esta é função que quero usar: https://github.com/ntruchsess/arduino_uip/blob/ext/uipclientext.cpp#l110 aqui o local onde quero inserir: https://github.com/fernandogarcia/feduino_with_webcontrol_beta/blob/master/feduino_with_webcontrol_beta/webserver.ino#l12 a intenção é limitar uma requisição para um determinado ip. eu tentei mover função "remoteip" para classe "uipclient" mas, função retorna um ip errado. grato. fernando garcia infelizmente não consigo ajudar. eu sou mais de c que de c++. sei o básico c++, mas "classe amiga", já me ultrapassa. ainda assim fui espreitar o código, e realmente, não vou lá. espero que consiga resolver o problema. cumprimentos.

Generating random numbers takes too long!

my led multiplexing code operates @ rate of 20-30 µs per column. want add random behavior, random() function takes as 130 µs per call. if try call while multiplexing, last column appears flash brighter. my temporary workaround generate large number of random ints array beforehand, during setup, limited paltry flash size. does know of quicker way generate random numbers on fly? maybe: http://sensorium.github.io/mozzi/doc/html/group__random.html#details quote these replace arduino random() slow stop audio. can used generate audio noise. i not know how granular library is, not know if there bloat issue... but, try it. ray Arduino Forum > Using Arduino > Project Guidance > Generating random numbers takes too long! arduino

Thread: Virtually mounting .ISO files?

the titles pretty explains it, running ubuntu 9.04, , need program allow me virtually mount iso file. since don't have dvd drive, pathetic little cd drive had since windows 2000 days , isn't mounting distros, iso files larger standard 700mb disk.. so have dvd iso on hard drive need mount drive? 1) create folder want mount it. personally, mount drives in home folder because eliminates permission issues. however, ubuntu defaults /media folder when automounting drives. it's you. i'm going write assuming use home directory code: mkdir desktop/mount can put somewhere else (besides desktop) , rename mount else, remember alter commands below if do. 2) mount iso code: sudo mount /path/to/iso desktop/mount -o loop the /path/to/iso part iso location. example, have xbmc linux iso, , here's command use sudo mount /home/justin/desktopxbmc_live.iso desktop/mount -o

LED RGB - Transición del espectro del arco iris

hola todos: en este post, explicaré todos los elementos necesarios, como conectarlos y el sketch para el correcto funcionamiento. el hardware necesario es el siguiente: placa arduino (en este caso due rev3) led rgb (5mm) 3 resistencias (el cálculo de valores lo explicare más adelante) 4 cables de conexión macho-macho placa de pruebas (donde se realizará el montaje) también es necesario conocer las especificaciones de todos los elementos utilizar, en este caso, sólo es necesario la hoja de especificaciones del led rgb. en esta hoja encontraremos los datos necesarios para el cálculo de las resistencias utilizar y para que se utiliza cada pin del led. en la imagen 140836.jpg, aparece rodeado de rojo el esquema con los pines. se trata de un led de ánodo común, esto quiere decir que, con un solo cable se alimentará los tres colores, y las resistencias se tienen que poner en los pines de los colores. para entenderlo simplemente hay que aplicar lógica inversa, cuando ponemos un valo

parallel port for cnc - Raspberry Pi Forums

hi every one, since time wish build own cnc. bought breakout board , drivers based in tb6550. nevertheless, based in parallel port many other options. emc2 in linuxcnc has parallel interface well. after many hours surfing in internet mind mess. starting point use rpi2. in order use breakout board here first question: has developed , interface convert gpio header in parallel port can comunicate breakout board emc2 ? of course need 3.3-5vots converter, conscient. second idea that, if stepper motor driver needs 4 gpios, rpi2 has enough several, so... why not avoid breakdown board , connect drivers directly header. has developed control motors directly emc2 through headers?. again 3.3-5vots converter. 3rd option interface parallel2serie can conect usb of rpi2 breakout board through usb2parallel converter wire. read re usb not adequate real time control. nevertheless people has developed like: http://forum.arduino.cc/index.php?topic=92561.new#new needs arduino , not more boards.

Servir un archivo al PC (como si fuera un pendrive)

buenas! acabo de empezar con arduino y me estoy embarcando en mi primer proyecto. en él necesito que la arduino genere un pequeño archivo (menos de 200 bytes) y este sea accesible por el pc. la idea es que el aparato vaya enchufado un usb y funcione como un pequeño pendrive en el que aparece este archivo si se cumplen una serie de condiciones y desaparece si no se cumplen. estado buscando pero no encuentro información clara sobre si se puede o no, en algunos foros leo que no se puede porque el usb de la placa es en realidad como un serial adaptado usb y en otros sitios que se puede, pero que como sería de un tamaño ínfimo no sería muy útil (aunque en mi caso por muy pequeño que sea me sirve...). mi idea es mantener el proyecto tan simple como sea posible, pero si tengo que añadirle algún módulo tampoco me importaría. ¿alguna sugerencia o indicación de por donde tirar? gracias ^^ hola: me parece que te estas metiendo en algo complicado. la parte de comunic

SSH for OSX

hi: i've been asked work in server w/o ftp server, ssh 1. can recommend ssh client graphical interface for osx? they're using ssh tectia client wich doesn't seem have mac version 2. ssh neccessary "normal" sites? because if is, guess of internet sites in danger tia, jdoe ssh secure terminal connection , nothing more. when someone says use ssh connect server, mean connect via terminal prompt (command line). there's no graphical tool this. now, if talking sftp (secure ftp) there number of options available you. dreamweaver's built-in ftp client connnect via sftp, panic's transmit ( http://www.panic.com/transmit/). transmit ftps (ftp on ssl). is ssh/sftp necessary? guess depends on ask , how secure they prefer networks be. lot of times it's preference on part of host. ssh , sftp connections encrypted, whereas telnet and ftp not. best regards, chris More discussions in Develop server-side applications in Dreamweaver
