/*********************************************************************************************\
This driver enables the display of the current time, numbers (both integers and floats) and
basic text on the IoTTimer clock.
Template {"NAME":"IoTTimer Lo","GPIO":[32,33,0,34,3872,1312,0,0,10944,10912,640,480,608,4768],"FLAG":0,"BASE":18}
In addition, it is possible to set brightness (seven levels plus off) and clear the display.
To use, compile Tasmota with USE_DISPLAY, USE_DISPLAY_TM1640 and USE_IOTTIMER, or build the tasmota-display
firmware.
Either use following template:
Template {"NAME":"IoTTimer Lo","GPIO":[32,33,0,34,3872,1312,0,0,10944,10912,640,480,608,4768],"FLAG":0,"BASE":18}
or configure manually:
For the IoTTimer clock assign the pins as follows from Tasmota's GUI:
GPIO12 --> "TM1640 DIN"
GPIO13 --> "TM1640 CLK"
Once the GPIO configuration is saved and the ESP8266/ESP32 module restarts, set the Display
Model to 13 and Display Mode to 0 using the command "Backlog DisplayModel 13 ; DisplayMode 0;"
Before using it, set the Display Type to 1 (for IOTTIMER) using the "DisplayType 1" command.
After the ESP8266 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"
DisplayFloat num
Clears and then displays float (with decimal point) command e.g., "DisplayFloat 12.3"
See function description below for more details.
DisplayFloatNC num
Same as DisplayFloatNC
DisplayClock 1|2|3|4
Displays a clock.
Commands "DisplayClock 1" // 12 hr format
"DisplayClock 2" // 24 hr format
"DisplayClock 3" // 12-hour without seconds
"DisplayClock 4" // 24-hour without seconds
In addition, if you compile using USE_DISPLAY_MODES1TO5, setting DisplayMode to 1 shows the time,
setting it to 2 shows the date and setting it to 3 alternates between time and date (using "DisplayRefresh [1..7]"
for the time and seconds you want to show the time before displaying the date)

(specifically for its use in the IOTTIMER WiFi clock)
The WiFi LED clock called IOTTIMER has the following characteristics:
- Controlled by an ESP-12F
- Display with four 35 mm (1 12/32 in), two 21 mm (26/32 in), and three 12 mm (~1/2 in),
seven-segment LED digits, plus special symbols (alarm, AM/PM)
- TM1640B LED controller
- R8010 RTC with CR1220 battery
- Temperature sensor M1601
- Ambient light sensor (analog voltage)
- Buzzer
- Three buttons on the backside
- USB C port for power supply (only)
The TM1640B chip is a controller for a sixteen-digit seven-segment (plus dot) LED display.
It is also sometimes used to control a 16 x 8 LED matrix. The controller is controlled
through a proprietary two-wire serial interface bearing some similarities with I2C. The
two wires are called CLK and DIN. We use two GPIO pins and one-microsecond sleeps to
implement the required timing.
The wiring of the LEDs in the IOTTIMER clock has been optimized for a simple routing of the
traces on the display board. The enumeration of the digit segments is non-standard, but
consistent across all digits. The bigger digits have two LEDs per segment, controlled by
separate digit lines of the LED controller. From the software perspective, they appear as
two layers of four digits each.
The brightness of the LEDs can be controlled in seven steps (plus off). In theory, the
brightness of the segments with two LEDs could be set in fifteen levels (plus off).
To keep things simple and to avoid brightness gradients within segments, both LEDs of a
segment will always be set to the same level.
The intention of this display driver (together with the drivers for the other components)
is to be able to use the IOTTIMER as an alarm clock that can be fully integrated in your
home automation using Tasmota and rules.
This driver is not a generic TM1640B driver as use cases of the TM1640B in different
devices will differ significantly.
