If you want to put the D1 Mini ESP32 directly on the back of the display shield, make sure you only solder the 16 legs the D1 Mini ESP8266 has. The connector on the back of the display has the outer and inner pins 1-on-1 connected while on the ESP32 they are completely different.
Here we connect a 130×130 TFT display with an SSD1283A controller to an ESP8266 Wemos D1 mini microprocessor board. The D1 mini has a smaller footprint than an Arduino while it has more working memory and on board wifi. A BH1750 photometric sensor breakout board connected with the D1 mini measures ambient light intensity. The amount of energy reported by the BH1750 is calculated in Watts per square meter and in Lux. Successively the Lux values are displayed on the TFT screen where a retro-analog looking temperature gauge automatically switches through three scales. The required libraries,
Square displays are interesting devices because they offer graphic features that allows the mimicking of an analog watch or meter. Most Arduino compatible displays possess pixel dimensions that are a multiple of 8, e.g., 128×64, 128×160, 240×320 or 320×480. Such dimensions result in rectangular displays. For some applications one might favor a square display with sufficient pixel resolution. The 130×130 pixel TFT display breakout board described here is sold by several Chinese vendors. The on board controller is a SSD1283A chip. Screen diagonal is a comfortable 40 mm (1.6 inch) while the breakout board dimensions are 54×35 mm. One attractive feature of this TFT board is that full 16-bit color is available. In this example a 130×130 TFT display is on a prototyping breadboard connected with a Wemos D1 mini ESP8266 microprocessor board, running up to a future project that aims at the construction of a highly portable, wifi connected, light intensity data reporting unit. The light intensity sensor is a BH1750 breakout board with I2C connectivity.
The breakout 130×130 TFT display is placed onto a breadboard together with a Wemos D1 mini (ESP8266; NodeMCU and Arduino compatible). This assembly is combined with the BH1750 breakout light intensity sensor (figure 1). The BH1750 sensor is mounted on a separate bracket and supplied with a gray intensity filter borrowed from a camera, this in order to match the intensity of direct sunlight with the sensor’s dynamic range (see earlier post)
The SSD1283A controller of the TFT display requires instructions that can be compiled with the libraries,
figure 1: Schematic connectivity for a 130×130 pixel SPI TFT display with SSD1283A driver with a Wemos D1 mini. The breakout TFT board has eight pins: LED, SCK, SDA, A0, RST, CS, GND and VCC. The display is a 16-bit color transflective TFT. The sketch forces it to automatically scale in three ranges. Pins SCL and SDK of the BH1750 photometric sensor are connected with pins D2 and D1 of the D1 mini, respectively.
The TFT breakout board is advertised by the vendor as 3.3V. Its brightness and contrast however are low when it is powered at 3.3 V (brightness and contrast of the display in both figures 1 and 2 were enhanced with a bitmap editor). The display tolerates 5V, e.g. when combined with an Arduino Uno and then displays somewhat brighter. As it will be introduced in a 24/7 photometric sensing project the 3V power supply is maintained to assure a long life. The BH1750 photometric sensor is 3.3V compatible.

Two sketches are supplied here: a demo showing graphics that can be programmed, and a sketch that reads light intensity data from the BH1750 sensor and displays these with a retro-analog gauge type meter on the 130×130 TFT screen. Both sketches need the libraries LCDWIKI_GUI.h> and
The 130×130 SSD1283A TFT display performs well with an ESP8266 type microcontroller board such as the Wemos D1 mini. In a previous post this has already been demonstrated. One disadvantage of this particular TFT display running at 3.3V power supply with a Wemos D1 mini is its low luminosity, making it less useful in sunlight conditions.

The WeMos D1 Mini family of boards is one of the latest additions to the ESP8266-based IoT ecosystem. The WeMos D1 Mini 1.44" TFT Display Shield includes the popular, full color, 128×128 pixel resolution display for showing text, graphics, and even animations.
The embedded TFT driver (ST7735) can display full 16-bit color. It is internally wired to the display, and can be controlled over SPI using pins (D3 for TFT_DC and D4 for TFT_CS; reset can be set to -1 on your preferred software library). This fantastic shields also breaks out the display pins onto an 8-pin header. Whereas the pins for using the board as a WeMos D1 Mini shield come pre-soldered, to control the display using the 8-pin header option you"ll need to solder the included 8-pin header, and wire it to your preferred microcontroller or single-board computer (Arduino, Raspberry Pi, etc.).
This small form factor shield is a convenient way to get a display on your project with a very small footprint. What makes the WeMos family of development boards for the ESP8266 great is the availability of stackable, plug-and-play shields such as this WeMos D1 Mini 1.44" TFT Display Shield. The WeMos family is a great solution for building projects quickly using the ESP8266 SoC.

I am using a 3.5: TFT LCD display with an Arduino Uno and the library from the manufacturer, the KeDei TFT library. The library came with a bitmap font table that is huge for the small amount of memory of an Arduino Uno so I"ve been looking for alternatives.
What I am running into is that there doesn"t seem to be a standard representation and some of the bitmap font tables I"ve found work fine and others display as strange doodles and marks or they display upside down or they display with letters flipped. After writing a simple application to display some of the characters, I finally realized that different bitmaps use different character orientations.
Are these due to different target devices such as a Windows display driver or a Linux display driver versus a bare metal Arduino TFT LCD display driver?
What is the criteria used to determine a particular bitmap font representation as a series of unsigned char values? Are different types of raster devices such as a TFT LCD display and its controller have a different sequence of bits when drawing on the display surface by setting pixel colors?
Is there some method other than the approach I"m using to determine what transformation is needed? I currently plug the bitmap font table into a test program and print out a set of characters to see how it looks and then fine tune the transformation by testing with the Arduino and the TFT LCD screen.
With the size of this table and the small amount of memory on the Arduino Uno, I started hunting for other bitmap fonts that would be legible while also taking up less memory. See reducing memory required for KeDei TFT library used with 3.5" TFT display with Arduino
What I have run into is that while I have found several different examples of bitmap fonts not all seem to be compatible with my specific 3.5" TFT LCD display.
The bitmap font representations in the image above, showing the differences in text character orientation, were generated by a simple Windows GUI and displayed with a dash (-) representing a bit value of zero and an asterisk (*) representing a bit value of 1. This is the output of a Microsoft Windows GUI application whose WM_PAINT message handler which draws the displayed image is as follows:
I have modified the code that displays text using the bitmap fonts so that for a particular bit map the character drawing logic will perform several different kinds of translations between the bitmap font representation as a series of hexadecimal digits and how the series of digits are used to determine which pixels to turn on and which to turn off.
The code for drawing a single line of a character is as follows. The outline of this function is to provide to the LCD controller a rectangle specifying the region of the display to be modified followed by a series of two 8 bit writes to set the two byte RGB565 color value of each of the pixels in the region.

There are a number of font specifications including rasterized bitmap type fonts. These specifications do not necessarily describe the glyph bitmaps used in application such as the KeDei TFT library but rather provide a device independent description of a bitmap font format.

I am using a 1.8 Inch LCD Screen SPI Serial Port Module TFT Color Display Touch Screen ST7735 (128*160) for Arduino”, bought for 9€ from aliexpress.com.
Details: Display Processor: ST7735, Touch Processor: XPT2046, Display Type: ZJY180-TV2.0,128*160, as ESP8266 I am using the WEMOS D1 Mini Pro (v 2.0) https://wiki.wemos.cc/products:d1:d1_mini_pro.
Actually I got the Touchdisplay running at the RPI after a lot of tries – but what do I have on my desk: A big black RPI4 box with a touch-display. Not looking good.
My alternative: I build a tiny Touchdisplay with ESP8266 in a little box with battery, that I can place anywhere. I will communicate via WIFI to my RPI. No black box on the desk, just a cool multifunctional switch and status-display for RPI Remote control. Kind of a long running project – lets see how it goes.
Of course, from china – there is not much documentation. Below some information I found at AliExpress about the display and all contacts at the display have labels. To note: PEN (11) is high, and gets low, when the display is touched – so can be directly linked to the Wemos (see below).
This is a very nice ESP8266 processor, small size and including LiPo charger unit, so any 3.7V battery can be directly attached on it and can be charged via the mini USB. Its Pin-Compatible to the well known WEMOS Mini, that has some interesting soldering-pads on the back:
SLEEP: This connect the Reset and the XPD_DCD – Deep Sleep Wakeup, so the WEMOS can waket-up itself from Deep-Sleep. For easy programming and the serial interface to work, this should not be connected. So do it, before you put it into production
If its running with display connected, but without backlight (BLK to GND), its consuming 0.48 mA (500uA) – what is approx 100 days runtime, 3 month is ok
