I am using servoblaster from https://github.com/srcshelton/servoblaster
Is it possible to implement some sort of easing algorithm in python?
Example: The following will full speed move servo_x to 1125 at full speed and then back to starting position @ 2500...
servo_x=0
servo_x=(1,125.693)
ServoBlaster.write('P1-11=' + str(servo_x) + 'us' + '\n')
ServoBlaster.flush()
time.sleep(5)
servo_x=(2500)
ServoBlaster.write('P1-11=' + str(servo_x) + 'us' + '\n')
ServoBlaster.flush()
time.sleep(5)
Is there an equivalent to this arduino example?

Here he says: "To do this in Arduino/C code, a new intermediate position for the servo is specified for each main loop until it reaches the final position. The intermediate value is the sum of 95% of the current position, and 5% of the target position. This gives the effect of the natural motion described above. The ratios can be changed to suit the desired speed."
@5:16 in the video he adds a few variables into a loop:
void loop () {
switch1=digitalread(12)
switch1smoothed (switch1 * .05) + (switch1previous * .95)
switch1previous = switch1smoothed
}
I feel like the equivalent in the previous terms would be something like:
servo_x=0
servo_x2=0
servo_x3=0
servo_x=(1,125.693)
servo_x2=(servo_x*.05) + (servo_x3*.95)
servo_x3=(servo_x2)
ServoBlaster.write('P1-11=' + str(servo_3) + 'us' + '\n')
ServoBlaster.flush()
time.sleep(5)
but this does not work... I just end up sending one signal and would like to send a signal that trails off at the end smoothly. Is servoblaster capable of doing this or is this not possible?
