Programming LED functions with Python 3
The following example shows the programming of the LED functions with Python 3:
import sys
import time
# write red LEDs:
fw = open("/sys/class/leds/run_red/brightness", "w")
fw.write("1")
fw.close()
fw = open("/sys/class/leds/appl_red/brightness", "w")
fw.write("1")
fw.close()
fw = open("/sys/class/leds/err_red/brightness", "w")
fw.write("1")
fw.close()
# Wait for 5 seconds
time.sleep(5)
# write green LEDs:
fw = open("/sys/class/leds/appl_green/brightness", "w")
fw.write("1")
fw.close()
fw = open("/sys/class/leds/err_green/brightness", "w")
fw.write("1")
fw.close()
fw = open("/sys/class/leds/run_green/brightness", "w")
fw.write("1")
fw.close()
# Wait for 5 seconds
time.sleep(5)
