Hacking

On this February I decided to participate with a project to the SUSE Hackweek. ...

Natale si avvicina: mentre smanettavo su queste ottime PC Engines ALIX su cui ho installato una Debian modificata, ho scritto una comoda interfaccia per accendere/spegnere e far lampeggiare i led alla velocita’ desiderata… class Led #numero da 1 a 3 def initialize(ledno) ledno++ # passo 0 ma comando 1 ledno=1 if ledno<1 ledno=3 if ledno>3 @ledsyspath="/sys/devices/platform/leds_alix2/leds/alix:#{ledno}/" end def blink(millisec) File.open(@ledsyspath+'trigger','w') { |f| f.write('timer') } File.open(@ledsyspath+'delay_off','w') do |f| f.write(millisec.to_s) end File.open(@ledsyspath+'delay_on','w') do |f| f.write(millisec.to_s) end end def blink_slow! blink(500) end def blink_fast! blink(50) end def on! File.open(@ledsyspath+'trigger','w') { |f| f.write('default-on') } File.open(@ledsyspath+'brightness','w') do |f| f.write('1') end end def off! File.open(@ledsyspath+'trigger','w') { |f| f.write("none") } File.open(@ledsyspath+'brightness','w') do |f| f.write('0') end end end
