how can i check the High-nibbel and Low-nibbel?

-

hello,
sorry bad english.
i have byte e.g. 0x1a.
how can check high-nibbel , low-nibbel?

what arduino command highbyte() , lowbyte()?

can me?
thank you

you bitwise , (&) value 0x0f , 0xf0 pull high , low nibble; ie:

quote
byte high = (0x1a & 0xf0) >> 4; // bit-shift 4 places right value
byte low = 0x1a & 0x0f; // no bit-shifting needed


i think should work...

:)

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
