Arduino Alvik API
Para acceder a las funciones de Arduino Alvik API tenemos que ejecutar las instrucciones:
alvik = ArduinoAlvik()
alvik.begin()Entonces ya podemos usar las siguientes:
| FUNCION con sus Inputs | Outputs |
| stop() | para todas las funciones Alvik |
| is_on() | true si esta encendido false si esta apagado |
| is_target_reached() | true si ha enviado M o R en el mensaje |
| get_ack() | last_ack: el valor del último mensaje |
| stop() | para todas las funciones Alvik |
| get_orientation() | r: valor de balanceo p: valor de cabeceo y: valor de guiñada |

| get_imu() | las 6 anteriores |
| get_line_sensors() |

| brake() | Frena el robot |
| get_battery_charge() | battery_soc: el % de la batería |
| get_touch_any() | touch_any es true si se ha apretado cualquier botón |
| get_touch_ok() get_touch_cancel() get_touch_center() get_touch_up() get_touch_left() get_touch_down() get_touch_right() |
touch_ok es true si se ha apretado ok etc... |

|
rgb2hsv(r: float, g: float, b: float) |
h: hue value s: saturation value v: brightness value |
|
get_color(color_format: str = 'rgb') |
r or h g or s b or v |
|
hsv2label(h, s, v) |
color label: like "BLACK" or "GREEN", if possible, otherwise return "UNDEFINED" |
|
get_distance(unit: str = 'cm') |
lee la distancia del sensor TOF: ver ejemplo en https://libros.catedu.es/books/arduino-alvik/page/evita-obstaculos left_tof: 45° to the left object distance center_left_tof: 22° to the left object distance center_tof: center object distance center_right_tof: 22° to the right object distance right_tof: 45° to the right object distance |
|
get_distance_top(unit: str = 'cm') |
top_tof: 45° to the top object distance |
|
get_distance_bottom(unit: str = 'cm') |
bottom_tof: 45° to the bottom object distance |

Unidades
- m: centimeters
mm: millimeters
m: meters
inch: inch, 2.54 cm
in: inch, 2.54 cm - deg: degrees, example: 1.0 as reference for the other unit. 1 degree is 1/360 of a circle.
rad: radiant, example: 1 radiant is 180/pi deg.
rev: revolution, example: 1 rev is 360 deg.
revolution: same as rev
perc: percentage, example 1 perc is 3.6 deg.
%: same as perc - 'cm/s': centimeters per second
'mm/s': millimeters per second
'm/s': meters per second
'inch/s': inch per second
'in/s': inch per second - 'rpm': revolutions per minute, example: 1.0 as reference for the other unit.
'deg/s': degrees per second, example: 1.0 deg/s is 60.0 deg/min that is 1/6 rpm.
'rad/s': radiant per second, example: 1.0 rad/s is 60.0 rad/min that is 9.55 rpm.
'rev/s': revolution per second, example: 1.0 rev/s is 60.0 rev/min that is 60.0 rpm.
¿Qué es eso de bloking?
Por ejemplo en rotate(angle: float, unit: str = 'deg', blocking: bool = True)
Si es true, todos los eventos no influyen, es decir el microprocesador esta centrado en esa instrucción
Si es falso, el microprocesador es libre de hacer otra cosa a la vez
Utiliza true si quieres precisión o no quieres que nada interaccione con la acción que estas ejecutando
