i've read rpi works xbmc before started thought i'd ask drawbacks or gotchas might not anticipating. if want use pi media center, you'll want run 1 of distros dedicated this, i.e. raspbmc, xbian or openelec. make sure have power supply - lot of problems caused running pi under-spec psu. if use usb peripherals, connect them powered hub. if use hdd format ext4 [not ntfs]. if play content on network share, nfs performs better smb. playing hd content on wifi marginal - use wired ethernet if can. choose xbmc skin recommended pi. skins resource hungry. raspberrypi

is possible attach led 3.3 gpio pin using 220 ohm resistor instead of 330 ohm resistor? v=1.3 r=220 ohm i=0.006 a damage raspberry or led? no. 220 ohm resistor , led forward voltage of 1.3 volt means led current 3.3-1.3 = 2.0v / 220 ohm = 9ma max current per port pi can deliver 15ma, 9ma safe. doubt forward voltage of led 1.3v, more around 2.0v, led current 3.3 - 2.0 = 1.3v / 220 = 0.005909090 or 6ma, safer. seems more logical second scenario described. raspberrypi

ghp asked i18n support asap classes; sadly i'm not able make work yet. wait! there encouraging news. it's important subject i've left side until because, well, it's complicated , not think of lot of fun. (wrongly) had impression support had been pretty cut out of pi version of scratch due problems non-latin character rendering didn't seem urgent issue. ghp's prompting i've spent time looking again , got wrong end of stick somewhere - original system *does* in fact deal non-latin character sets on pi. sigh. bad news getting relevant vm plugin work newer vm non-trivial because working on build process , .. oh, never mind, it's annoying. news *can* minor experimenting by a) running nscratchb5.image on older installed vm (which works ok maybe ⅔rd performance of new vm) b) escaping development environment c) fiddling unicodeplugin class' "testing" methods force conversion of relevant strings utf8 strings ... , presto! can nice results ...

hi, this first post, , in traditional noob fashion cry help!! i have built filter wheel 9 positions, driven smal stepper motor on rim, , controlled arduino nano 3.0 , easydriver. it requires 22366 steps complete 1 complete revolution, , has mechanical switch act home position. i controlling arduino via the  serial monitor inputing filter number , wheel turnes position. changing position working correctly, code using set wheel home not. have been trying different things several days can't crack it. time admit defeat , ask help! here code; code: [select] int home_pin = 0;  // interrupt 0 on digital pin 2! int step_pin = 5;  //easydrver step pin. int current_position = 0; int new_position = 0; volatile int state = low;  // input state toggle // interupt state change, (if switch state changes, stop stepper , delay). void statechange() {   state = !state;   digitalwrite(step_pin, low);   delay(50000);   current_position=1;   serial....

i have written script uses pigpio library , sort of automates confidence test of gpios. script should run nothing connected gpios. each (user) gpio tested follows. 1) current mode , level read. 2) gpio set output , checked see if can written high , low. 3) gpio set input , checked see if internal pull-ups/downs can pull gpio high , low. pull-down test skipped i2c gpios have more powerful external pull-ups. 4) original mode , level restored. internal pull-ups switched off. script ends giving test summary. i've tested using rev.1 board. code: select all soft ~ $ /code/gpiotest program checks pi's (user) gpios. program reads , writes gpios. make sure nothing connected gpios during test. program uses pigpio daemon must running. start daemon use command sudo pigpiod. press enter key continue or ctrl-c abort... testing... skipped non-user gpios: 2 3 5 6 12 13 16 19 20 26 27 28 29 30 31 tested user gpios: 0 1 4 7 8 9 10 11 14 15 17 18 21 22 23 24 25 failed user ...
