USB webcam issues - Raspberry Pi Forums

-

i've got rpi setup 2 logitech usb webcams, , small cronjob takes picture using fswebcam every minute, , uploads server ncftp.
script gracefully restarts rpi every night, clean things up.
( there details of how i've done here. http://rpicam.blogspot.co.uk/

it's been working fine, ( weeks untouched ), i've started see errors appearing on 1 of webcams after few hours usage.

limited logs have show when working..

code: select all

opening /dev/video1... trying source module v4l2... /dev/video1 opened. --- capturing frame... captured frame in 0.00 seconds. --- processing captured image... setting title "husbos south". writing jpeg image 'picam02_1.jpg'. picture taken thu_11/07/13_06:11 picam02_1.jpg:                                          81.22 kb   12.75 kb/s   picture picam02_1.jpg uploaded thu_11/07/13_06:11
after few hours, start see

code: select all

--- opening /dev/video1... trying source module v4l2... /dev/video1 opened. --- capturing frame... vidioc_dqbuf: no such device no frames captured.
, on, wont take more images until rpi rebooted.

have 2 different usb webcams running on rpi,

code: select all

bus 001 device 002: id 0424:9512 standard microsystems corp.  bus 001 device 001: id 1d6b:0002 linux foundation 2.0 root hub bus 001 device 003: id 0424:ec00 standard microsystems corp.  bus 001 device 004: id 046d:081b logitech, inc. webcam c310 bus 001 device 005: id 046d:0825 logitech, inc. webcam c270 /dev/video0 /dev/video1
, 1 giving issues c270, on video1. c310 working faultlessly.

ideas whats causing vidioc_dqbuf error ? or heat getting webcam ?
cameras , rpi mounted outdoors in proper cctv enclosures, in sun day, , have had 'summer' here in uk week.. ( when problems started )

no solution, same issue me. c310 no more detected rpi after months of work...

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...
