Python Bindings
The Python bindings allow to modify the computer lights by using other programs signals. Some applications can be to modify the colors when receiving an email, when monitoring things like the weather or the CPU temperature.
Examples
Testing all the commands
This is the example that I use to test the bindings. It should be clear enough to explain all the commands !
#!/usr/bin/python3
#
import time
from AKBL.Bindings import Bindings
AKBLConnection=Bindings()
lights_test=True
profiles_test=True
colors_test=True
speed_test=True
colors_multiple_test=True
if not AKBLConnection.ping():
print("The connection with the daemon is off")
exit()
"""
Each command is called as:
print( <command_name>, <command> )
To check if the commands succeed. You don't
really need to do this in your code!
"""
if lights_test:
print('lights off', AKBLConnection.set_lights(False))
time.sleep(2)
print('lights on', AKBLConnection.set_lights(True))
time.sleep(2)
print('switch lights', AKBLConnection.switch_lights())
if profiles_test:
for profile_name in AKBLConnection.get_profile_names():
print('set profile:', profile_name, AKBLConnection.set_profile(profile_name))
time.sleep(5)
color1='#F7F200'
color2='#0018FF'
if colors_test:
print('set_colors blink', AKBLConnection.set_colors('blink', 100, color2))
time.sleep(5)
print('set_colors fixed', AKBLConnection.set_colors('fixed', 100, color1))
time.sleep(5)
print('set_colors morph', AKBLConnection.set_colors('morph', 100, color1, color2))
if speed_test:
print('set_colors blink', AKBLConnection.set_colors('blink', 1, color2))
time.sleep(5)
print('set_colors blink', AKBLConnection.set_colors('blink', 100, color2))
time.sleep(5)
print('set_colors blink', AKBLConnection.set_colors('blink', 256, color2))
time.sleep(5)
if colors_multiple_test:
colors1='#0600FF'
colors2='#FF00E5'
print('set_colors multiple blink', AKBLConnection.set_colors('blink', 100, colors2))
time.sleep(5)
print('set_colors multiple morph', AKBLConnection.set_colors('morph', 100, colors1, colors2))
time.sleep(5)
print('set_colors mutlple fixed', AKBLConnection.set_colors('fixed', 100, colors1))
Changing the keyboard colors by checking the CPU Temperature
The following script will change the keyboard colors by checking the CPU Temperature. Before using the script, you should
check in a terminal if you have the command sensors
#!/usr/bin/python3
#
import os
import time
from AKBL.Bindings import Bindings
def get_max_temp():
"""
Get the maximum temperature of the CPU by
using the bash commands "sensors"
"""
output=os.popen('''sensors''')
lines= output.readlines()
max_temperature=0
for line in lines:
if '°C' in line:
temp = line.split('+')[1]
temp = temp.split('°')[0]
temp = float(temp)
if temp > max_temperature:
max_temperature=temp
return max_temperature
if __name__ == '__main__':
akbl=Bindings()
if not akbl.ping():
print("The akbl daemon is off.")
else:
while True:
max_temperature=get_max_temp()
print("The maximum temperature is", max_temperature)
if max_temperature <= 0:
akbl.set_colors('fixed', 100, '#000000') # black
elif max_temperature <= 20:
akbl.set_colors('fixed', 100, '#02EDFF') # cyan
elif max_temperature <= 55:
akbl.set_colors('fixed', 100, '#0000FF') # blue
elif max_temperature <= 70:
akbl.set_colors('fixed', 100, '#FFE900') # yellow
elif max_temperature <= 85:
akbl.set_colors('fixed', 100, '#FF7800') # orange
elif max_temperature <= 95:
akbl.set_colors('fixed', 100, '#FF0014') # red
else:
akbl.set_colors('blink', 100, '#FF0014') # red
time.sleep(5) # seconds
Note that if you want to test the code, you can just create a fake temperature:
else:
max_temperature=0
while True:
#max_temperature=get_max_temp()
.
.
.
max_temperature+=10
time.sleep(5)
Changing the keyboard colors by checking the weather
I was curious to find if there was command line weather program, and it seems that inxi works fine :)
#!/usr/bin/python3
#
import os
import time
from AKBL.Bindings import Bindings
def get_max_temp():
"""
Get weather temperature and make a linear
scale: 40°C <==> 100
(The linear scale is only to adapt this function
to the previous script)
"""
# get the temperature
output=os.popen('''inxi -w''')
line=output.read()
try:
temp_str=line.split(' C')[0].split('(')[1]
max_temperature=float(temp_str)
except Exception as e:
print(e)
max_temperature=0
# adapt it
max_temperature=(max_temperature*10)/4
return max_temperature
if __name__ == '__main__':
akbl=Bindings()
if not akbl.ping():
print("The akbl daemon is off.")
else:
while True:
max_temperature=get_max_temp()
print("The maximum temperature is", max_temperature)
if max_temperature <= 0:
akbl.set_colors('fixed', 100, '#000000') # black
elif max_temperature <= 20:
akbl.set_colors('fixed', 100, '#02EDFF') # cyan
elif max_temperature <= 55:
akbl.set_colors('fixed', 100, '#0000FF') # blue
elif max_temperature <= 70:
akbl.set_colors('fixed', 100, '#FFE900') # yellow
elif max_temperature <= 85:
akbl.set_colors('fixed', 100, '#FF7800') # orange
elif max_temperature <= 95:
akbl.set_colors('fixed', 100, '#FF0014') # red
else:
akbl.set_colors('blink', 100, '#FF0014') # red
time.sleep(5) # seconds
