Struct sensehat::SenseHat [−][src]
pub struct SenseHat<'a> { /* fields omitted */ }Represents the Sense HAT itself.
Methods
impl<'a> SenseHat<'a>[src]
impl<'a> SenseHat<'a>pub fn new() -> SenseHatResult<SenseHat<'a>>[src]
pub fn new() -> SenseHatResult<SenseHat<'a>>Try and create a new SenseHat object.
Will open the relevant I2C devices and then attempt to initialise the chips on the Sense HAT.
pub fn get_temperature_from_pressure(&mut self) -> SenseHatResult<Temperature>[src]
pub fn get_temperature_from_pressure(&mut self) -> SenseHatResult<Temperature>Returns a Temperature reading from the barometer. It's less accurate than the barometer (+/- 2 degrees C), but over a wider range.
pub fn get_pressure(&mut self) -> SenseHatResult<Pressure>[src]
pub fn get_pressure(&mut self) -> SenseHatResult<Pressure>Returns a Pressure value from the barometer
pub fn get_temperature_from_humidity(&mut self) -> SenseHatResult<Temperature>[src]
pub fn get_temperature_from_humidity(&mut self) -> SenseHatResult<Temperature>Returns a Temperature reading from the humidity sensor. It's more accurate than the barometer (+/- 0.5 degrees C), but over a smaller range.
pub fn get_humidity(&mut self) -> SenseHatResult<RelativeHumidity>[src]
pub fn get_humidity(&mut self) -> SenseHatResult<RelativeHumidity>Returns a RelativeHumidity value in percent between 0 and 100
pub fn get_orientation(&mut self) -> SenseHatResult<Orientation>[src]
pub fn get_orientation(&mut self) -> SenseHatResult<Orientation>Returns a vector representing the current orientation, using all three sensors.
pub fn get_compass(&mut self) -> SenseHatResult<Angle>[src]
pub fn get_compass(&mut self) -> SenseHatResult<Angle>Get the compass heading (ignoring gyro and magnetometer)
pub fn get_gyro(&mut self) -> SenseHatResult<Orientation>[src]
pub fn get_gyro(&mut self) -> SenseHatResult<Orientation>Returns a vector representing the current orientation using only the gyroscope.
pub fn get_accel(&mut self) -> SenseHatResult<Orientation>[src]
pub fn get_accel(&mut self) -> SenseHatResult<Orientation>Returns a vector representing the current orientation using only the accelerometer.
pub fn get_accel_raw(&mut self) -> SenseHatResult<Vector3D>[src]
pub fn get_accel_raw(&mut self) -> SenseHatResult<Vector3D>Returns a vector representing the current acceleration in Gs.
pub fn show_message<INT, FG, BG>(
&mut self,
message: &str,
interval: INT,
fg: FG,
bg: BG
) -> SenseHatResult<()> where
INT: Into<Duration>,
FG: Into<Colour>,
BG: Into<Colour>, [src]
pub fn show_message<INT, FG, BG>(
&mut self,
message: &str,
interval: INT,
fg: FG,
bg: BG
) -> SenseHatResult<()> where
INT: Into<Duration>,
FG: Into<Colour>,
BG: Into<Colour>, Displays a scrolling message on the LED matrix. Blocks until the entire message has scrolled past.
The interval can be a std::time::Duration or an Fps (frames per
second).
The fg and bg values set the foreground and background colours.
You can either specify:
- a constant colour like
Colour::WHITE, - a string from the W3C basic keywords like
"white"or"purple", or - an RGB 8-bit triple like
(0, 0xFF, 0).
pub fn text<FG, BG>(
&mut self,
message: &str,
fg: FG,
bg: BG
) -> SenseHatResult<()> where
FG: Into<Colour>,
BG: Into<Colour>, [src]
pub fn text<FG, BG>(
&mut self,
message: &str,
fg: FG,
bg: BG
) -> SenseHatResult<()> where
FG: Into<Colour>,
BG: Into<Colour>, Displays a scrolling message on the LED matrix. Blocks until the entire message has scrolled past. Scrolls at a fixed 10 frames per second.
The fg and bg values set the foreground and background colours.
You can either specify:
- a constant colour like
Colour::WHITE, - a string from the W3C basic keywords like
"white"or"purple", or - an RGB 8-bit triple like
(0, 0xFF, 0).
pub fn clear(&mut self) -> SenseHatResult<()>[src]
pub fn clear(&mut self) -> SenseHatResult<()>Clears the LED matrix
