Arduino timer

-

how access timer?  is there handle?

i verify time required compute calculation.

more i'm computing position acceleration , need time calculate integral.

thanks!

if milliseconds precise enough, can use millis() returns number of milliseconds since last reset. stick current value of millis() in variable, execute task, call millis() again , substract previous value number of elapsed milliseconds.

if worried millis() taking time , messing accuracy, can test replacing task delay(10) , seeing if 10 elapsed ms. try different values , if error (if any) consistent, can substract error results in final sketch.

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
