Raw segments can also be displayed. In addition, it is also possible to set brightness (8 levels), clear the display, scroll text, display a rudimentary bar graph, and a Clock (12 hr and 24 hr). To use, compile Tasmota with USE_DISPLAY and USE_DISPLAY_TM1637, or build the tasmota-display env. For TM1637: Connect the TM1637 display module's pins to any free GPIOs of the ESP8266 module and assign the pins as follows from Tasmota's GUI: DIO hardware pin --> "TM1637 DIO" CLK hardware pin --> "TM1637 CLK" For TM1638: Connect the TM1638 display module's pins to any free GPIOs of the ESP8266 module and assign the pins as follows from Tasmota's GUI: DIO hardware pin --> "TM1638 DIO" CLK hardware pin --> "TM1638 CLK" STB hardware pin --> "TM1638 STB" For MAX7219: Connect the MAX7219 display module's pins to any free GPIOs of the ESP8266 module and assign the pins as follows from Tasmota's GUI: DIN hardware pin --> "MAX7219 DIN" CS hardware pin --> "MAX7219 CS" CLK hardware pin --> "MAX7219 CLK" Once the GPIO configuration is saved and the ESP8266/ESP32 module restarts, set the Display Model to 15 and Display Mode to 0 using the command "Backlog DisplayModel 15 ; DisplayMode 0" If your display is a TM1637 with 6 digits, set Display Width to the number of digits your display has, using the command "DisplayWidth 6". After the ESP8266/ESP32 module restarts again, turn ON the display with the command "Power 1" Now, the following "Display" commands can be used: DisplayClear Clears the display, command: "DisplayClear" DisplayNumber num [,position {0-(Settings->display_width-1))} [,leading_zeros {0|1} [,length {1 to Settings->display_width}]]] Clears and then displays number without decimal. command e.g., "DisplayNumber 1234" Control 'leading zeros', 'length' and 'position' with "DisplayNumber 1234, , , " 'leading zeros' can be 1 or 0 (default), 'length' can be 1 to Settings->display_width, 'position' can be 0 (left-most) to Settings->display_width (right-most). See function description below for more details. DisplayNumberNC num [,position {0-(Settings->display_width-1))} [,leading_zeros {0|1} [,length {1 to Settings->display_width}]]] Display integer number as above, but without clearing first. e.g., "DisplayNumberNC 1234". Usage is same as above. DisplayFloat num [,position {0-(Settings->display_width-1)} [,precision {0-Settings->display_width} [,length {1 to Settings->display_width}]]] Clears and then displays float (with decimal point) command e.g., "DisplayFloat 12.34" See function description below for more details. DisplayFloatNC num [,position {0-(Settings->display_width-1)} [,precision {0-Settings->display_width} [,length {1 to Settings->display_width}]]] Displays float (with decimal point) as above, but without clearing first. command e.g., "DisplayFloatNC 12.34" See function description below for more details. DisplayRaw position {0-(Settings->display_width-1)},length {1 to Settings->display_width}, num1 [, num2[, num3[, num4[, ...upto Settings->display_width numbers]]]]] Takes upto Settings->display_width comma-separated integers (0-255) and displays raw segments. Each number represents a 7-segment digit. Each 8-bit number represents individual segments of a digit. For example, the command "DisplayRaw 0, 4, 255, 255, 255, 255" would display "[8.8.8.8.]" DisplayText text [, position {0-(Settings->display_width-1)} [,length {1 to Settings->display_width}]] Clears and then displays basic text. command e.g., "DisplayText ajith vasudevan" Control 'length' and 'position' with "DisplayText , , " 'length' can be 1 to Settings->display_width, 'position' can be 0 (left-most) to Settings->display_width-1 (right-most) A caret(^) symbol in the text input is dispayed as the degrees(°) symbol. This is useful for displaying Temperature! For example, the command "DisplayText 22.5^" will display "22.5°". DisplayTextNC text [, position {0-Settings->display_width-1} [,length {1 to Settings->display_width}]] Clears first, then displays text. Usage is same as above. DisplayScrollText text Displays scrolling text. DisplayScrollDelay delay {0-15} // default = 4 Sets the speed of text scroll. Smaller delay = faster scrolling. DisplayLevel num {0-100} Display a horizontal bar graph (0-100) command e.g., "DisplayLevel 50" will display [|||| ] DisplayClock 1|2|0 Displays a clock. Commands "DisplayClock 1" // 12 hr format "DisplayClock 2" // 24 hr format "DisplayClock 0" // turn off clock In addition, setting DisplayMode to 1 shows the time, setting it to 2 shows the date and setting it to 3 alternates between time and date. \*********************************************************************************************/ #define XDSP_15 15 #define CMD_MAX_LEN 55 #define LEVEL_MIN 0 #define LEVEL_MAX 100 #define SCROLL_MAX_LEN 50 #define POSITION_MIN 0 #define POSITION_MAX 8 #define LED_MIN 0 #define LED_MAX 255 #define MAX7219_ADDR 0 #include "SevenSegmentTM1637.h" #include #include SevenSegmentTM1637 *tm1637display;
