thomo / Sandbox Anleitung.md
Created April 25, 2016 12:36
Anleitung für die Einrichtung einer "Terraforming Sandbox" entsprechend http://idav.ucdavis.edu/~okreylos/ResDev/SARndbox/

  • Terminal Fenster öffnen (Symbol ">_")

  • "./start_sandbox.sh" eingeben -> enter

  • es erscheint ein Fenster "RawKinectViewer"

    • links: "Tiefenbild" der Kinect (eher blau)

    • rechts: Kamarabild der Kinect

    • Ausschnitt des Tiefenbilds vergößern, so dass Sandbox möglichst groß zu sehen ist

DHT22 example (Lua 5.4.1, NodeMCU SDK 1.4.0)
-- pin = 3 -- GPIO0
pin = 4 -- GPIO2
FLOAT_FIRMWARE = (1/3) > 0
function readDht()
status, temp, humi, temp_dec, humi_dec = dht.read(pin)
if status == dht.OK then
if FLOAT_FIRMWARE then
-- Float firmware using this example

Created December 22, 2012 14:29
Patched tcpip.cpp file from avr-netino (http://code.google.com/p/avr-netino/) version avr-netino-19Jan2012.zip - add support of receiving udp packets
// IP, Arp, UDP and TCP functions.
// Author: Guido Socher
// Copyright: GPL V2
//
// The TCP implementation uses some size optimisations which are valid
// only if all data can be sent in one single packet. This is however
// not a big limitation for a microcontroller as you will anyhow use
// small web-pages. The web server must send the entire web page in one
// packet. The client "web browser" as implemented here can also receive
// large pages.
