Topic: Firmata + servo + pulseMin et pulseMax (Read 519 times) previous topic - next topic



je tente la question aussi sur le forum arduino.

Je voudrais piloter un servo avec processing via firmata.
dans la dernière version du protocole, servo a été implémenté mais je trouve pas d'exemple pour piloter correctement un servo via les messages...comme décrit sur la page de firmata.

une idée ?
(google trouve pas grand chose de récent et correcte)

la page firmata

Code: [Select]
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.
/* servo config
* --------------------
* 0  START_SYSEX (0xF0)
* 1  SERVO_CONFIG (0x70)
* 2  pin number (0-127)
* 3  minPulse LSB (0-6)
* 4  minPulse MSB (7-13)
* 5  maxPulse LSB (0-6)
* 6  maxPulse MSB (7-13)
* 7  angle LSB (0-6)
* 8  angle MSB (7-13)
* 9  END_SYSEX (0xF7)

comment fait-on un config ?
moi bête stupide ;)

merci d'avance

(et bonne année. :% c'est fait)
