Problems powering raspi + peripherals - Raspberry Pi Forums

-

i posting here it's more useful ripping hair out in fustration :d
powering model b pi off normal htc mobile charger. the september 2012 image of raspbian wheezy, ok keyboard , mouse alone (both bog-standard hp kit) not d-link powered 4-port usb hub (looks http://i01.twenga.com/computers/hub/d-l ... 1448vb.jpg) nothing plugged it. thought fine, i'll use more recent version of raspbian wheezy, may 2013. pi boots fine, not respond it's keyboard or mouse. when boots, noted treats devices not connected error -110 , nither respond device nor plugged in instead of later. sure must problem power, when did hub working, red pwr led on pi flickered power led on hub flickered, , plugging in hub when pi has booted causes reboot. i've tried powering pi through pc , through hub connected pc, similar results.
buggs me had set before, same usb hub , keyborad/mouse , htc phone charger on different pi (an earlier model b) no problems whatsoever.
ideas causing this? i'm stumped!

hmm, wonder if hub powering pi.
usb hubs there "uplink" cable used connect hub host computer/pi.
can test have pi powered up, usb hub connected , powered on... unplug charger powering pi...

pi stay on? if hub powering pi. wonder if causing problem.
if happening can prevent cutting red (+5v) wire inside uplink cable.

may want tests without usb hub @ all, verify okay pi , keyboard alone.

ATmega2560-Arduino Pin Mapping

hi community, in last days working on project using arduino mega 2560. on planning pin using found bugs in atmega2560-arduino pin mapping . if right there labels (such pwm) in 'mapped pin name' @ wrong row ( mixed pin numbers right one...) in attachment openoffice calc , pdf file corrected table. ( hope ;-) ) i post here tab separated table : code: [select] arduino mega 2560 pin mapping table atmega 2560 pin out arduino mega function nr name function function function mapped pin name function function datasheet 1 pg5 oc0b digital pin 04 pwm 2 pe0 rxd0 pcint8 digital pin 00 rx0 (usart0 receive pin, programming data input or pin change interrupt 8) 3 pe1 txd0 digital pin 01 tx0 (usart0 transmit pin or programming data output) 4 pe2 xck0 ain0 (usart0 external clock  input/output) 5 pe3 oc3a ain1 digital pin 05 pwm 6 pe4 ...

Crossfader Arduino Tutorial

-
hello i'm super newb please don't bash me much. i'm using led's , i've connected them correctly (finally) , wondering why program here ( http://www.arduino.cc/en/tutorial/colorcrossfader ) doesn't work? say's haven't declared crossfade. read directions on top , said crossfade needs used list order of colors. isn't declared in main part (void loop() )? or need declared before? nevermind void on bottom , needed before voidloop. lol anyways playing rgb led's wondering if has specific way of making them fade in , out different colors? (brightness , color mixing) code: [select] /* * code cross-fading 3 leds, red, green , blue (rgb) * create fades, need 2 things: *  1. describe colors want displayed *  2. list order want them fade in * * describing color: * color array of 3 percentages, 0-100, *  controlling red, green , blue leds * * red red led @ full, blue , green off *   int red = { 100, 0, 0 } * dim white 3 l...
