Serial rx/tx port setting

-

hi all,

is there way change rx , tx ports used hardwareserial? effectively, have dte devices need talk each other - don't have null modem handy. figure if can arduino reverse these 2 pins (rx on 0, tx on 1), won't need it.

one option use softwareserial, in can allocate ports, i'd use built-in usart if possible..

is possible?

you can hook rx 1 side tx on other. devices need link , sort of ends have?

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
