The arduino_timer
file provides a soft timer witch is used by quite all devices.
Message
timer < timer_start(delay : Int16)
: Start a timer for delay
milliseconds.timer < timer_cancel()
: Cancel the current timer.timer > timer_timeout()
: The timer is over.There are three ways to use digital input. All of them use same messages.
Messages
DigitalInput < read_digital_input()
: Request the value.DigitalInput > digital_input_value(value : DigitalState)
: The digital sate of the component.The digital state is send only when it is requested.
Configuration
In addition to send the result when it is requested, the digital state is send periodically every refresh_rate
milliseconds.
Configuration
In addition to send the result when it is requested, the digital state is send at every change.
Configuration
Enables to set a digital state on a pin.
Messages
DigitalOutput < set_digital_output(value : DigitalState)
: Set value
as the digital state.Configuration
Three types of analog input can be used. All of them use same messages but keep in mind that some properties can differ.
Messages
AnalogInput < read_analog_input()
: Request the analog value.AnalogInput > analog_input_value(value : Int16)
: The analog value.The value of the analog pin is send only when it is requested.
Configuration
In addition to send the result when it is requested, the value is send periodically every refresh_rate
milliseconds.
Configuration
In addition to send the result when it is requested, the value state is send when a change is detected. To avoid too many messages the value is checked every 20 milliseconds by default (refresh_rate
). Moreover to prevent fake changes there is a value_precision
property which enables to fix the threshold which determine if the value has changed. The default value is 1. Keep in mind a value of 1 imply that the analog value has to vary at least of 2 to get refreshed.
Configuration
Enables to set a PWM value between 0 and 255 on a pin.
Messages
Pwm < set_pwm_value(value : UInt8)
: Set value
as PWM value.Configuration
