having updated pi use new iot released around 25th june, xbox controller not longer recognised. else having problems or other hid devices? oak hi all, in update post, we've upgraded windows 10 iot core release version , xbox 360 controller still no longer detected. got little robot kit build conference year , have gradually been adding functionality, we're kind of @ standstill now. plug xbox controller in, ring round xbox button on controller lights 1 1/2 seconds , goes out. there's no indication of in connected devices. on fault finding front i've tried: tried on 2 different raspberry pi's, 2 different memory cards, 2 different iot downloads, 2 different power supplies (and cables), 2 different xbox controllers. we've tried using powered usb hub in case controller attempting draw more current pi usbs can provide. else have similar problems? else have xbox controller working windows 10 iot release? raspberrypi

i have project requires alarm once day.  accuracy not critical, thought i'd test out arduino duemilanove  , see how close 24 hours long delay.  ran following command, hoping delay 24 hours: delay(86400000); that's 24 hours * 60 minutes * 60 seconds * 1000 milliseconds. after 24 hours, arduino less 1 second off.  that's amazing, considering there isn't real time clock.  basic operations high precision not necessary, length of delay works well.  thought i'd pass along else considering long delays. thats great, no 1 uses delays. experienced programmer tell never use delays throughout code, instead use millis() or micros() function keep track of time. edit: find.

hallo zusammen, ich habe mein erstes programm in assembler geschrieben auf meinem arduino uno um laufen gebracht und etwas merkwürdiges festgestellt. habe alle 8 pins von portd auf 1 gesetzt und möchte damit den pins 0-7 eine rote led mit 220 ohm widerstand schalten. das funktioniert auch soweit einwandfrei. aus interersse habe ich den strom mal den jeweiligen pins gemessen und habe folgendes ergebnis: wenn nur eine led angeklemmt ist, habe ich dem jeweiligen pin 69ma gemessen. wenn zwei leds angeklemmt sind, habe ich den jeweiligen pins 59ma gemessen. wenn drei leds angeklemmt sind, messe ich 55ma und mit vier leds 48ma usw. wieso sinkt der strom allen pins, je mehr leds ich anklemme??? 40ma sollte ja auch das absolute maximum pro pin sein und 200ma ganzen controller. lg ben du hast offensichtlich nicht 220 ohm als vorwiderstand genommen (rot rot braun) sondern viel weniger - mit 220 ohm müssten etwa 15ma durch die led fließen. du ziehst viel strom aus d...
