Procédures et fonctions

Instantiate a tm1638 module specifying the display state, the starting intensity (0-7) data, clock and stobe pins.

TM1638(byte dataPin, byte clockPin, byte strobePin, boolean activateDisplay = true, byte intensity = 7);

Set the display to a unsigned hexadecimal number (with or without leading zeros)

void setDisplayToHexNumber(unsigned long number, byte dots,boolean leadingZeros = true, const byte numberFont[] = NUMBER_FONT);

Set the display to a unsigned decimal number (with or without leading zeros)

void setDisplayToDecNumber(unsigned long number, byte dots,boolean leadingZeros = true,const byte numberFont[] = NUMBER_FONT);

Set the display to a signed decimal number (with or without leading zeros)

void setDisplayToSignedDecNumber(signed long number, byte dots,boolean leadingZeros = true, const byte numberFont[] = NUMBER_FONT);

Set the display to a unsigned binary number

void setDisplayToBinNumber(byte number, byte dots,const byte numberFont[] = NUMBER_FONT);

Set the LED at pos to color (TM1638_COLOR_RED, TM1638_COLOR_GREEN or both)

virtual void setLED(byte color, byte pos);

Set the LEDs. MSB byte for the green LEDs, LSB for the red LEDs

void setLEDs(word led);

Returns the pressed buttons as a bit set (left to right).

virtual byte getButtons();

Set the display (segments and LEDs) active or off and intensity (range from 0-7).

virtual void setupDisplay(boolean active, byte intensity);

Set a single display at pos (starting at 0) to a digit (left to right)

virtual void setDisplayDigit(byte digit, byte pos, boolean dot,const byte numberFont[] = NUMBER_FONT);

Set the display to an error message

virtual void setDisplayToError();

Clear a single display at pos (starting at 0, left to right)

void clearDisplayDigit(byte pos, boolean dot);

Set the display to the values (left to right)

virtual void setDisplay(const byte values[], unsigned int length = 8);

Clear the display

virtual void clearDisplay();

Set the display to the string (defaults to built in font)

virtual void setDisplayToString(const char* string, const word dots =0,const byte pos = 0, const byte font[] = FONT_DEFAULT);

Set the display to the String (defaults to built in font)

virtual void setDisplayToString(String string, const word dots = 0, const byte pos = 0,const byte font[] = FONT_DEFAULT);
