Hello, i'm confused.
i would like to control a servo with processing interface.
I saw firmata and the last version that add servo support.
i'm interesting by the pulseMin and pulseMax fonction...
in the firmata page
and the sentences
This is the current proposal for adding Servo support based on feedback from Bjoern Hartmann, Shigeru Kobayashi, and Erik Sjodin. The core idea is to just add a "config" message, then use the SET_PIN_MODE message to attach/detach Servo support to a pin. This is how hardware PWM is currently handled. This would save space in the protocol by reusing the SET_PIN_MODE message, but the host software implementation could have a different interface, e.g. Arduino's attach() and detach().
minPulse, maxPulse, and angle are all 14-bit unsigned integers. Angle is in degrees. The SERVO_CONFIG can be sent at any time to change the settings.
sorry i don't understand (my english understanding 
) what i have to do to send an analogic message to the arduino...
any helps will be greats
regards
