Arduino processing capacity

-

i'm trying run several motors , servos, connected arduino via h-bridge, using joystick connected pc , sending serial data arduino. i've got arduino receiving joystick data, need 1 byte each motor direction, i've ended using arduino write 8 bytes of data 8 pwm pins. i've noticed appreciable delay in arduino's response time , have had add several slow-downs in programming @ both ends in order reduce mixed signals, , yet i'm still getting lot of improper pin firing. reaching limit of arduino's processing power or doing wrong?

do have mega, standard arduino has 6 pwm pins. perhaps if have connected easier advise

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
