logic shifter use case - Raspberry Pi Forums

-

hi all,

electronics noob here. quick question. can give me 'use case' want use logic shifter used raspberry pi gpio pins?

lets this: http://www.ebay.co.uk/itm/mini-logic-le ... 4aba0064b7

i'm curious on sort of applications people use these?

thanks

from pi (3.3v) 5v wouldn't need (low @ 3.3v still recognised low @ 5v, , high @ 3.3v still recognized high @ 5v).

5v pi might cause problem. logic 1 5v device if 5v damage pi. in case converter protect pi lowering signal 3.3v.

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
