SainSmart 2.8" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and mutilfunctional module for your project.The Screen include a controller ILI9325, it"s a support 8/16bit data interface , easy to drive by many MCU like arduino families，STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is XPT2046 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.

Voltage type: 5v or 3v voltage input voltage，input is selectable. Because TFT can only work under 3.3 V voltage, so when the input voltage VIN is 5V, need through the 3.3 V voltage regulator IC step down to 3.3V , when the input voltage of 3.3 V, you need to use the zero resistance make J2 short , is equivalent to not through the voltage regulator IC for module and power supply directly.

This is a 2.8” TFT Resistive Touchscreen Display. The module, with a resolution of 320x240, adopts ILI9341 as driver IC and SPI (4-line) communication mode. The board integrates touch chip XPT2046, which converts the touch data collected by the AD to SPI data. The module also integrates an SD card slot allowing you to easily read the full-color bitmap. There are two modes of wiring supplied, normal pin header wiring and GDI. The latter one requires to work with a main controller board with a GDI interface (e.g. FireBeetle-M0). You can use it with only one FPC line plugging in, which reduces the complexity of the wiring. Furthermore, it features high resolution, wide viewing angle, and simple wiring, which can be used in all sorts of display applications, such as, IoT controlling device, game console, desktop event notifier, touch interface, etc.

Backlight. The backlight is set to the default value, and the user can light up without connecting the backlight pin; in addition, when the backlight pin is connected, input high level (1) to adjust the backlight brightness to the maximum, input low level (0) to turn off the backlight

This product is Breakout module with SPI communication mode and GDI interface, which reduces the wiring complexity and makes it easy to display what was read from the SD card.

WARNING: BTT does not officially provide MKS TFT hardware support. MKS TFT is maintained by open source contributors and BTT does not bear any risk of MKS TFT hardware using this firmware.

IMPORTANT NOTE: The Master branch is currently the ONLY branch in the project to be used. The other currently existing branches develop and release-xx.27 are outdated and MUST NOT be used.

In case your mainboard provides EXP1 and EXP2, you have to connect 2 ribbon cables connecting EXP1 and EXP2 of the mainboard to EXP1 and EXP2 of the TFT. In the Marlin firmware of your mainboard, make sure that ONLY REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER is activated in Configuration.h and that all other controllers are Deactivated (especially CR10_STOCKDISPLAY).

In case you have an "E3" mainboard which provides a single EXP connector, you have to connect 1 ribbon cable connecting EXP of the mainboard to EXP3 of the TFT. In case your TFT does not provide an EXP3 connector but only two 10pin connectors (TFT24 v1.1 for example) you will need a "Y-split" cable with one 10pin connector on one side (for the mainboard) and two 10pin connectors on the other side (for the TFT). In the Marlin firmware of your mainboard, make sure that ONLY CR10_STOCKDISPLAY is activated in Configuration.h and that all other controllers are Deactivated (especially REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER).

Any binary file for an MKS firmware (e.g. MKS_TFT28_V4.0.27.x.bin) MUST be renamed to MKSTFT*.bin (e.g. MKSTFT28.bin, MKSTFT35.bin etc.) in order it can be recognized and installed by the TFT

The firmware configuration can be modified by changing the config.ini (or the renamed config_rrf.ini) file using a simple text editor (make sure to use UTF encoding).

A configuration can be uploaded without the need to upload the firmware or the TFT folder again, as long as the firmware and the configuration file are from the same version (see Configuration Update).

NOTE: For devices with USB flash drive support, it is possible to update the icons, fonts, config and the language files from a USB flash drive in the same way it is done through an SD card. However, the firmware can only be updated using an SD card.

Copy the precompiled BIGTREE_TFT*_V*.*.*.bin or your self compiled firmware, plus the TFT* folder of your preferred theme along with config.ini to the root of a blank SD card not greater than 8GB and formatted as FAT32:

Optionally, copy one or more language_*.ini file(s) onto the SD card. Doing so, it will allow you to switch between English and the uploaded language(s) from the Language menu present in the TFT firmware. We recommend to upload the minimum amount of languages to keep the memory usage low. The language_*.ini file can be edited to change the text shown on the TFT:

Place the SD card with BIGTREE_TFT*_V*.*.*.bin, the TFT* folder, config.ini and the optional language_*.ini file(s) into the TFT"s SD card reader and reset your TFT (or optionally - power cycle your printer) to start the update process:

In case one or several parts of the update failed, an error will be shown. Follow the information on the screen to update the missing or outdated elements:

After the update is done and the files are renamed, it is possible to reuse them again. To do so, change the name of the element(s) to the pre-update name and start the update process again.

Touch Screen Calibration menu: A post installation process is needed before switching to Main menu. Please, see Post Installation section for completing the post installation process

In case major changes have been applied by the installed firmware, a post installation process consisting on touch screen calibration is automatically started.

For devices with USB flash drive support, it is possible to update the icons, fonts, config and the language files from a USB flash drive in the same way it is done through an SD card. However, the firmware can only be updated using an SD card

The hard reset process is typically used as the last chance when the firmware is not properly working (e.g. in case of freezes, errors on screen etc.)

Unless the default hard coded settings have been properly configured (e.g. a self compiled firmware was installed), after an hard reset the TFT typically needs to be reconfigured with the proper config.ini file (see Configuration Update)

When the default hard coded settings are properly configured for a TFT and the TFT"s basic function such as surfing on the menus is working, in case of issues the user can opt to apply only a configuration reset (soft reset) instead of an hard reset.

A BIGTREE_TFT*_V*.*.*.bin file will be generated in the hidden .pio\build\BIGTREE_TFT*_V*_* folder. Follow the update process outlined in the Firmware Update section above to update your TFT to the latest version

TIP: In case there is a problem compiling the TFT firmware try to restart VSC. If this does not help and you are using macOS, delete the packages and platforms folders usually present under the folder /Users/***username***/.platformio/.

All the precompiled firmwares available on Copy to SD Card root directory to update folder are compiled to support the standard (horizontal) screen orientation.

In case the TFT needs to be placed with a vertical orientation (e.g. 90°), the firmware needs to be compiled with the portrait mode support and installed following the procedure below:

NOTE: With only power supplied, you should be able to navigate through the menus using the touchscreen and even to switch to Marlin Mode (if available). Marlin Mode will not show any interface without a proper EXP connection (see Marlin Mode Setup).

OctoPrint, ESP3D, Pronterface etc, connected to a TFT"s serial port, can browse files on both the TFT"s and mainboard"s media devices and start a print that will be handled by the host (TFT or mainboard). The following actions and the related triggering G-codes are currently supported by the TFT fw:

OctoPrint, ESP3D, Pronterface etc, connected to a TFT"s or mainboard"s serial port, can host a print (print handled by the host) and optionally can trigger some actions to the TFT sending specific G-codes. The following actions and the related triggering G-codes are currently supported by the TFT fw:

The remote host must properly handle the received notifications. For example, if //action:notification remote pause is received then the remote host must effectively pause the print and send M118 P0 A1 action:pause in order to trigger the pause action to the TFT.

With the exception of TFT70, the maximum number of displayable layer count is 999 (there"s no space to display layer number and count if the layer count is above 999)

The other type is to store the thumbnails using dedicated comments (thumbnail begin... and thumbnail end) which is implemented in stock by some slicers like Prusa-Slicer.

The most recent version of the standard bigtreetech TFT firmware has built in support for RepRap firmware. The pre-built images have this enabled by default.

The TFT35 E3 V3.0 has 3 cables to connect to the mainboard. Two 10 pin ribbon cables and one 5 pin serial cable. The 2 ribbon cables connect to the EXP1 and the EXP2 connections on both the TFT35 E3 V3.0 and the MKS mainboards.

The RS232 cable is connected to the RS232 connection on the touchscreen, with the other end connecting to the AUX1 connection on the mainboard. The RS232 cable has 5 wires. One end has a single 5 wire connector that goes to the RS232 connector on the touchscreen, and the other end has two connectors, one has 4 wires, and the second one has one wire. That single wire is for the Reset and is not used on these MKS mainboards. The 4-pin connector plugs into the AUX1 connection. It must connect to the top row of pins when looking at the socket with the notch facing away from the mainboard and must be also plugged in with the 5v+ wire connected to the first pin in the upper left corner of the socket. The RESET wire is not connected to anything.

NOTE: On the MKS mainboards there is an issue that involves at least the MKS GEN_L, MKS SGEN, and MKS SGEN_L models. The EXP1 and EXP2 connections have the socket shell installed wrong way around. The notch that indexes the cable should be facing towards the mainboard. If you get a blank screen on the TFT35 E3 V3.0 touchscreen after connecting the two EXP cables and turning the printer on, turn printer off and disconnect the 10 pin cables from either the touch screen or the mainboard and using small diagonal cutters trim the tab down to be as close to flush as you can get on both cables (and only on one end) and plug them back in with the trimmed tab now facing the mainboard.

The second workaround for this issue is to carefully pry the two shells surrounding the pins on the mainboard upwards until they clear the pins. Do NOT use a metal tool for this, use a sturdy plastic or whalebone prying tool. Turn the shell 180 degrees and align the pins with the holes in the shells and push the shells back on with your thumb. Do not push the shell back on with something that could cause damage if it were to slip. Once the shells are installed you can use the stock (unaltered) cables as they are.

Edit the Configuration.h file and enable (uncomment) REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER. Rebuild and deploy the Marlin firmware to your 3D Printer.

Statistics as filament length, filament weight and filament cost can be embedded into the G-code. After the print is finished there will be an infobox that you can click and a popup will present you the printed filename (limited to the first 25 characters), the time needed for the print, the filament length used, the filament weight and its cost. In the case of multi-filament usage the statistics will show the sum of all individual data (sum of length, sum of weight, sum of cost).

In case filament data is not present in the G-code, the filament length data is calculated during print. Length is calculated regardless of using the TFT USB, TFT SD or the onboard media. Calculations are done in both absolute or relative extrusion mode. Filament data takes into account the flow rate also but with a caveat. It has to be the same flow rate during the entire time of the printing, because the end result is calculated based on the flow rate at the time the print has finished. If flow rate changes during the print the results will not be accurate anymore.

Think is, before I try to modify any library to bend it for the STM32L0 I wanted simply to check my SPI configuration by issuing a simpliest thing, reading LCD ID registers. But that"s the thing, I do not receive any data from ILI9341. I guess all registers are accessible right after the proper reset of the ILI9341, right? So, here is my "init" procedure:

please, see attached screen from my logic analyzer. You can see, CS is brrought low followed by eight clock pulses (500 kHz period) on SCK and 0x04 MSB first on the MOSI and with the DC set low. Afterwards, there is sequence of 4 dummy 0xFF bytes to push out the desired data out from the ILI9341 SPI buffer with the DC set high. But as you can see, there are only zeros on MISO line. Of course, the CS is brought up at the end. I"ve checked the wiring 10 times and I don"t think it is the problem. Maybe, are really all register accessible right after the start of the ILI9341? Or do I have to wirte some data somewhere first?
