do lcd displays have firnware made in china

Marlin deals with a variety of different displays and needs to display a lot of different languages in different scripts on them, within their capabilities. The system described here solves some of the related problems that need to be overcome with in a limited environment.

On all these displays you can define 8 custom symbols to display at once. In Marlin these characters are used on the Boot Screen, and on the Info Screen for the Bed Temp, Degree symbol, Thermometer, “FR” (feed-rate), Clock, and Progress Bar. On the SD Card listing screens some of these characters are re-used again for Up-level, Folder, and Refresh.

Graphical displays provide complete freedom to display whatever we want, so long as we provide a program for it. Currently we deal with 128x64 Pixel Displays and divide this area into ~5 Lines with ~22 columns. So we need monospace fonts with a bounding box of about 6x10. Until now we’ve been using a custom Marlin font similar to ISO10646-1 but with special symbols at the end, which made ‘ü’ and ‘ä’ inaccessible at 6x10 size.

The upshot of all this is that on Western displays you’ll see a ‘~’ while on Cyrillic an “arrow coming from top - pointing to left” (which is quite the opposite of what the programmer wanted). The Germans want to use “ÄäÖöÜüß”, the Finnish at least “äö”. Other European languages want to see their accents too. For other scripts like Cyrillic, Japanese, Greek, Hebrew, … you have to find totally different symbol sets.

The Japanese translator dealt with two scripts, introducing a special font for Graphical Displays and making use of the Japanese extended character displays. Thus he ended up with two pretty unreadable language.h files full of ‘\xxx’ definitions. Other languages either tried to avoid words that included special symbols or just used the basic symbols without the accents, dots… whatever.

On a full-featured desktop system like Windows or Linux we could install unifont.ttf and some library code and we’d be done. But embedded systems have very limited resources! So we must find ways to limit the space used (unifont.ttf alone is ~12MB!), requiring some compromise.

Make output functions that count the number of chars written and switch the font to Marlin symbols and back when needed. (ultralcd_impl_DOGM.h) (ultralcd_impl_HD44780.h)

Make three fonts to simulate the HD44780 charsets on dogm-displays. With these fonts the translator can check how the translation will look on character-based displays.

Make ISO fonts for Cyrillic and Katakana - because they don’t need a mapping table, are faster to deal with, and have a better charset than the HD44780 fonts. (Less compromise!)

Split ‘dogm_font_data_Marlin.h’ into separate fonts and delete. (+dogm_font_data_6x9_marlin.h, +dogm_font_data_Marlin_symbols.h, -dogm_font_data_Marlin.h)

If you make extensive use, your file will look like language_kana.h and your language file will only work on one of the displays (in this case DISPLAY_CHARSET_HD44780 == JAPANESE).

If you want to make use of more than a few symbols outside standard ASCII or want to improve the portability to more types of displays, use UTF-8 input. Which means defining another mapper.

Mapper functions will only catch the ‘lead-in’ described in the mapper’s name (e.g., C2C3). If the input doesn’t match, the mapper will output a ‘?’ or garbage.

The mapper_tables do their best to find a similar symbol in the HD44780fonts (for example, replacing small letters with the matching capital letters). But they may fail to find a match and will output a ‘?’. There are combinations of language and display which simply have no corresponding symbols - like Cyrillic on a Japanese display or _vice-versa. In those cases the compiler will throw an error.

In short: Choose a mapper that works with the symbols you want to use. Use only symbols matching the mapper. On Full Graphic Displays all symbols should be fine. Using the graphical display, you can test for bad substitutions or question-marks that would appear on character displays by defining SIMULATE_ROMFONT and trying the different variants.

If you get a lot of question marks on the Hitachi-based displays with your new translation, maybe creating an additional language file with the format language_xx_utf8.h is the way to go.

If there’s no existing mapper for your language then things get a bit more complex. With the Hitachi-based displays you can’t make something useful without a matching charset. For graphical display… let’s take the example of Greek: Find a matching charset. (Greek and Coptic)

The length of strings (for menu titles, edit labels, etc.) is limited. “17 characters” was a crude rule of thumb. Obviously 17 is too long for a 16x2 display. So, language files are free to check the LCD width and provide shorter strings in the following manner:

On 16x2 displays, strings suited to a 20x4 display will be chopped to fit. So if shorter string isn’t provided, at least make similar strings different early in the string. (‘Someverylongoptionname x’ -> ‘x Somverylongoptionname’)

Strings in language.h are for serial output, so don’t require any translation. Core error strings must always be in English to satisfy host protocols.

To find out which character set your hardware uses, set #define LCD_LANGUAGE test and compile Marlin. In the menu you’ll see two lines from the upper half of the character set: JAPANESE displays “バパヒビピフブプヘベペホボポマミ”

LCD_LANGUAGE: The LCD language and encoding to compile in. For example, pt-br_utf8 specifies Portuguese (Brazil) in UTF-8 format with a mapper. For a faster, lighter, but non-accented translation you might choose pt-br instead.

SIMULATE_ROMFONT: Languages can opt to use the HD44780 ROM font special characters on graphical display. This method can be used for accented Western, Katakana, and Cyrillic if they don’t supply their own fonts, or just for testing character-based mappers on a graphical display.

MAPPER_ONE_TO_ONE: Most character sets on graphical displays (including SIMULATE_ROMFONT) map the character index directly to its position in the upper half of the font. This is possible for character sets that have only 2 contiguous pages of Unicode containing all the special characters. Other mappers use logic or a lookup table to locate the glyph.

Most features of these firmware files are exclusive to the RTD-2556T model, models that exclude the T at the end do not have the required ram to make these features work.

There are programmers that claim to support the RTD ISP, but I have not tested them, if you are willing to try and ok with the possibility it will not work here is a MStar programmer

I figured I might have fried some internal component by moving the tray manually – did I force some little motor to spin at speeds wildly out of the expectations of the designers?

At first I hadn’t considered that I’d flashed the firmware. I was under the impression that you needed an Arduino and a bunch of cables to do that. That was in fact the case with the original Ender.

This guide will show you how to put a custom boot screen onto your 3D Printer. Why would you want to do that? Maybe you want to show off your printer. Or maybe you"re making a custom firmware and want to personalise it when you distribute it. In any case, creating a custom boot screen is a great way to learn both how to modify the Marlin firmware, as well as how to upgrade your printer"s firmware.

In this guide, I will be flashing a custom firmware onto a Creality Ender 5. The process will be similar on other machines, especially Creality machines, but as long as it runs Marlin this guide will work. You will simply have to download the appropriate pre-made configuration for your printer and mainboard.

If you"re using an image that isn"t the correct resolution, you"ll have to crop it down so the converter will accept it. One way to do this is with the open source GNU Image Manipulation Tool, or GIMP. Using GIMP can seem pretty complex, but what we"re doing is very simple.

Here"s what you want to do:Load you image into GIMP - you can do this by launching GIMP and selecting File > Open..., then navigating to the folder your image is in and selecting it. You should see a screen like the first image.

Making sure the width and height are linked, set the size to be at least less than 128x64 - if you have a tall image, set it to 64. If you have a wide image, set it to 128. As long as both values are smaller than this it will work correctly

Once you have your image, you"ll need to convert it into a format that your printer will understand. Doing this is very simple: all you have to do is navigate to the Marlin Bitmap Converter. On that site, simply click the Browse... button and select your image.Note: If you image is all one color, then you don"t have enough contrast in your image. to fix this, simply re-open the image in GIMP and select Colors > Level... and adjust the input levels until you get a black and white image.

At the bottom of the page, you will see a few options. Select Marlin 2.x and choose invert, if you want your image to be inverted. Once you have the image converted, keep the browser tab open and move on the the next step.

Once you download the firmware, extract it to a folder of your choice. From there, navigate into the folder you extracted it to, and open the Marlin folder. The next step is to download the correct configuration. Download and extract the latest release of the configurations, and open the folder corresponding to your printer. Since I"m using a Creality Ender 5, I"ll navigate to ./config/examples/Creality/Ender-5/CrealityV1.

Next, what you need to do is to copy the *.h files into the folder that your stock firmware is in. Make sure you overwrite the stock firmware, and not make a copy.

Open the Marlin.ino file in the Marlin folder of the firmware (where you placed all the configuration files). Once the Arduino IDE opens, select the tab named _Bootscreen.h. If the tab doesn"t exist, then create a file call _Bootscreen.h. Open the file, and delete anything that is in the file. Copy the code that was generated on the converter website into your empty _Bootscreen.h file.

Compiling may seem like the most complicated step, but it is fairly straight-forward. All you have to do is make sure that you have the correct board and Arduino type selected. Since I"m using a Creality V1 board, I need to install a separate library that allows me to compile for my board. Look up specific details for what libraries are required for your specific printer online.

Once you have all the required libraries, simply select Sketch > Verify/Compile. (or you can press Ctrl-R). If it compiles with no errors, you are good to move on the next step. Compiling may take a while, especially on slower computers. Be prepared for it to take a while, even up to an hour on especially slow computers.

If you get errors over USB like timeouts or if it is unable to connect, you most likely do not have a USB bootloader. You will have to program it over something else, like the ISP port on the mainboard.

If all went well, simply restart your printer, and you should see your new boot screen. Otherwise, you may have to try uploading again. If it still fails, look up the error the Arduino IDE is giving you and follow whatever help you find on the internet.

Uploading your new firmware through OctoPrint (or a similar web interface) can be a bit more complicated, but it has the advantage that you won"t have to move your computer or change your printer setup.

Once you have the Firmware Updater plugin open, click Browse... next the the from file label. Browse to where you have your compiled firmware and select the file that does not include bootloader in the name. If you do upload that file, you risk irreversibly damaging your printer. The plugin will also warn you if it detects a bootloader. If you see this warning, make sure that you cancel the firmware update.

If you would like to go further into customising your printer, you can check out Marlin"s configuration documentation page to see what all the options do.

If you don"t have an Arduino or ISP programmer, you can use a Raspberry Pi instead! You will have to be comfortable with a Command line interface, but it will work in a pinch. You can find some more information here.

If all else fails, and you can"t get your printer to update, then you may want to invest in a new mainboard. If you can afford it, they are often more reliable than stock mainboards, especially in cheap Chinese printers like Creality, and often include a USB bootloader from the factory. These also often have bigger Arduino cores that can have more features than the stock boards.
