Trait spark_ser7seg::SevenSegInterface [−][src]
Associated Types
type InterfaceError
[src]
A single error type used by the interface
Required methods
fn send(&mut self, data: &[u8]) -> Result<(), Error<Self::InterfaceError>>
[src]
Sending commands to the interface
Provided methods
fn set_cursor(&mut self, col: u8) -> Result<(), Error<Self::InterfaceError>>
[src]
Set the digit cursor to a particular location
col
may be 0..=3, from left to right.
fn set_brightness(
&mut self,
bright: u8
) -> Result<(), Error<Self::InterfaceError>>
[src]
&mut self,
bright: u8
) -> Result<(), Error<Self::InterfaceError>>
Set the brightness for the display. The datasheet says that 100 is the brightest, however my device gets brighter with values above 100 (up to 255). Your mileage may vary.
fn clear(&mut self) -> Result<(), Error<Self::InterfaceError>>
[src]
Completely clear the display
fn write_digit(&mut self, digit: u8) -> Result<(), Error<Self::InterfaceError>>
[src]
Write a digit to the curent cursor position. This also increments the cursor position
fn write_punctuation(
&mut self,
punct_flags: PunctuationFlags
) -> Result<(), Error<Self::InterfaceError>>
[src]
&mut self,
punct_flags: PunctuationFlags
) -> Result<(), Error<Self::InterfaceError>>
Write the requested punctuation to the display. This does not take
the current state into account, so any unset flags in punct_flags
will turn the corresponding LEDs off.
fn write_digits(
&mut self,
digits: &[u8]
) -> Result<(), Error<Self::InterfaceError>>
[src]
&mut self,
digits: &[u8]
) -> Result<(), Error<Self::InterfaceError>>
Write the requested digits to the display, starting at the current cursor position. Each digit must be in the range 0x0..=0xF, and up to 4 digits may be updated at once. The cursor is incremented after each digit
fn set_num(&mut self, num: u16) -> Result<(), Error<Self::InterfaceError>>
[src]
Write the number to the display. The number will be left-filled with zeroes if necessary. After this function, the cursor will be at position 0.
