Anschluss eines ESP8266 an einen Arduino Due mit TFT

hallo leute, ich bin neu hier und habe letzte jahr angefangen etwas mit arduinos zu experimentieren. jetzt habe ich mein erstes projekt fertig und es läuft  . und zwar hab ich ein wetterstation projekt mit einem arduino due und einem tft-display nachgebaut: http://educ8s.tv/arduino-wireless-weather-station/#comment-598 jetzt möchte ich das projekt erweitern um einen co2-sensor und ein wlan-modul (esp8266). das problem ich jetzt habe ist, dass ich nicht weiß wie ich das wlan-modul anschließen soll weil das display alle digitalen pins belegt. das display mit der pinbelegung ist dieses: http://www.banggood.com/3_0-inch-320-x-480-tft-lcd-display-module-support-arduino-mega2560-p-963573.html?rmmds=search so wie ich das verstanden habe brauche ich für das esp8266 den digitalen pin 53 due wie hier: http://arduino-er.blogspot.de/2015/04/connect-esp8266-wifi-module-to-arduino.html wie bekomme ich das esp8266 modul trotzdem angeschlossen? vg, masterkey2 beim d...

Thread: Is there a backup program for Ubuntu?

hi have laptop windows xp , ubuntu 9.10 dual-boot, on 2 partitions. in community told me need backup ubuntu because linux people make new version of every 6 months , need reinstall ubuntu. wanted confirm , ask means didn't understand completely. if have backup ubuntu, know if there special program can me adding small partition on computer save backup. similiar thing exists windows, called "rescue , recovery". save me having burn cds. there quite few programs can use backup system on linux, depends on how want backup, , want backup. far backing up, boil down personal preference, although people on here can give suggestions.. use dropbox backup documents , such. yes, ubuntu put out new version every 6 months; in april , october. can either reinstall upgrade, or there option upgrade system without fresh install... once again, boils down personal preference. hope helps some.. ...
