Do you have a project that needs a display, a key pad, and some memory, but the preloaded firmware on the Crystalfontz CFA735 or CFA835 module isn’t quite what you’re looking for? You’re in luck – these modules can be modified to load custom firmware.

The CFA735 and CFA835 are versatile intelligent LCD modules. Both the Crystalfontz CFA735 and CFA835 are based on the CFA10052 hardware module, so during this tutorial the CFA735 and/or CFA835 will be referred to as the CFA10052. The CFA10052 can be reprogrammed to run your own custom firmware.

The Crystalfontz CFA10052 hardware modules ship programmed with a bootloader and CFA735 or CFA835 firmware. The bootloader and CFA735/CFA835 firmware are not open-source, and cannot be copied off of the CFA10052 by the user, nor can they be programmed onto the CFA10052 by the user. Once a CFA735 or CFA835 is programmed with custom firmware, the module will lose all CFA735/CFA835 functionality. If you end up wanting the CFA 735 or CFA835 firmware loaded back onto your module, you’ll have to ship it back to us to reload it.

If you are using Windows 7/8/8.1/10 (or equivalent Server versions) and would like to test the USB virtual serial port, you’ll need to download drivers from here. The USB serial port will work without requiring additional drivers on Windows 10+, Linux, OS-X.

We recommend using the STM32CubeIDE to load and use this example firmware project. STM32CubeIDE is a free IDE based on Eclipse that has been modified by STMicroelectronics to include STM32 specific tools. The IDE can be downloaded on the STM32CubeIDE webpage.

Hold the up & down keys on the CFA10052 while plugging the USB cable into the CFA10052 (or power supply).The CFA10052 should now show the Crystalfontz Bootloader screen.

Run the STM32 ST-LINK Utility. In the “Target” menu, open the “Option Bytes” window. In the “Read Out Protection” box, select “Level 0”. Click Apply. The Crystalfontz firmware has now been removed and any custom firmware may now be programmed.

Run the STM32 ST-LINK Utility.In the “Target” menu, open the “Option Bytes” window.In the “Read Out Protection” box, select “Level 0”. Click Apply.The Crystalfontz firmware has now been removed and any custom firmware may now be programmed.

Now that you’ve removed the supplied firmware, you’re ready to compile and load your own firmware. For the purposes of this tutorial, we have supplied some alternative firmware that gives keypad control of the backlight brightness and display contrast.

The above steps are only required on loading the project for the first time in STM32CubeIDE. After firmware source-code changes have been made, only re-building the project (Ctrl-B shortcut) and programming the CFA10052 (F11 key shortcut) are needed.

Devices that you might think of as strictly hardware such as an optical drive, network card, TV remote, router, media player, camera, or scanner all have software that"s programmed into a special memory contained in the hardware itself.

For example, let"s say you buy a 20-pack of empty BD discs and try to burn a video to a few of them, but it doesn"t work. One of the first things the Blu-ray drive manufacturer would probably suggest is to update/flash the firmware on the drive.

Network router manufacturers release updates to firmware on their devices to improve network performance or add additional features. The same goes for digital camera makers, smartphone manufacturers (like iOS and Android), etc. You can visit the manufacturer"s website to download these updates.

One example can be seen when downloading the firmware for a wireless router like the Linksys WRT54G. Just visit that router"s support page on the Linksys website to find the downloads section, which is where you get the firmware.

For example, you might be able to update the firmware on a gaming console by just accepting any prompts to update the software. It"s unlikely that the device is set up in a way where you have to manually download the firmware and then manually apply it. That would make it much too hard for the average user to perform updates, especially if the device needs to be updated often.

Apple devices like iPhones and iPads also occasionally get firmware updates, as do Android phones and tablets. These devices let you download and install the firmware from the device itself so you don"t have to do it yourself manually. Typically, firmware updates for mobile devices are obtained wirelessly, in which case they might be called firmware-over-the-air (FOTA) or over-the-air updates.

However, some devices, like most routers, have a dedicated section in the administrative console that lets you apply a firmware update. This is generally a section that has anOpen or Browse button that lets you select the firmware you"ve downloaded. It"s important to review the device"s user manual before doing this, just to make sure the steps you"re taking are correct and you"ve read all the warnings.

See how to upgrade your router"s firmware if that"s what you"re doing, or visit your hardware manufacturer"s support website for more information on firmware updates.

Just as any manufacturer warning will display, it"s extremely important to make sure the device that"s receiving the firmware update doesn"t shut down while the update is being applied. A partial update leaves the firmware corrupted, which can seriously damage how the device works.

It"s equally critical to avoid applying the wrong update to a device. Giving one device a piece of software that belongs to a different one can result in that hardware no longer functioning like it should. It"s usually easy to tell if you"ve downloaded the right firmware by just double-checking that the model number corresponding to that firmware matches the model number of the hardware you"re updating.

Like we already mentioned, another thing to remember when updating firmware is that you should first read the manual associated with that device. Every device is unique and will have a different method of updating or restoring a device"s firmware.

Some devices don"t prompt you to update, so you have to either check the manufacturer"s website to see if an update has been released or register the device on the manufacturer"s website so that you can get emails when the new firmware comes out.

Download the firmware update (directly from the manufacturer, if possible), then log into your router"s settings hub and find the firmware section. It varies by manufacturer, but can often be found under Advanced or Management. Look for an option to update the software, then follow the on-screen directions to apply the firmware update and reboot your router.

First, before updating your AirPods, make sure you need an update by going to Settings> Bluetooth>Informationicon > About. If a firmware patch is available, download and install it by putting the AirPods in their case, then connecting the case to a power source. Be sure to keep the case near your iPhone.

If your TV has power and it"s connected to your home"s Wi-Fi, it should automatically download and install updates. If your TV is turned turned off, go to Settings > Support > Software Update > Auto Update (or Update Now) to update the firmware.

Downscaler behavior can be controlled in the [Interp./Deint.] menu. DS Pass-Thru = No, forces all sources to the specified output (i.e. 480i is converted to 240p). DS Pass-Thru = Yes has the output resolution follow the input resolution.

Please be aware, that downscaling options are considered experimental and unsupported. We cannot provide support or guarantee proper operation with 3rd party HDMI -> analog dongles. You will need a converter that is capable of recognizing and generating the correct sync signals for 480i video.

First of all, thank you so much everyone for making the RetroTINK-5X a reality. I could not have imagined the interest and growth that this project has experienced over the past year. This was all possible only due to the tremendous support from the community.

8. Hit "Flash". The update process should start. If the window freezes, that is okay - the update should complete after a minute or two. Just be patient.

Big thanks to RetroRGB who was kind enough to put this video together. He was generous enough to make this video. Please do not contact him for technical support.

Reverted some settings that might have caused instability with SNES and other consoles. For difficult systems, like the SMS and NEOGEO AES use the "Strong" LPF setting. For all other systems use "Off", "Light" or "Medium".

We can confirm that a PAL GCN with a RGB SCART cable (use one designed for PAL consoles NOT NTSC) works as well as the official OEM component cables and the Insurrection Industries Carby with an external HDMI -> YPbPr converter box. The RGB approach seems to have some image quality issues, though, so we"d recommend a solution that uses the GC"s digital AV port.

Unfortunately the Carby Component Cable does not work. The HD Retrovision on a PAL GCN also does not work. We do not know if a modded GCN works, but are told that it should.

In many cases, installing the latest updates for Windows will fix the issue. For more info, see Update Windows 10. Here are some other things to check:

Select Check for updates. If updates are available, they will install automatically. You may need to restart your device after the updates have installed.

Make sure the USB end of the adapter is plugged into a USB power source. If the second display doesn"t have a USB charging port, use the charging port on a device power supply or another USB charger.

The Microsoft Wireless Display Adapter app provides settings and firmware updates for the adapter. If you haven’t already done so, install the app from Microsoft Store. For info on how to install the app, go to Use the Microsoft Wireless Display Adapter.

Check for updates on your device after trying this solution. To do that, select Start> Settings> Update & Security> Windows Update, select Check for updatesand install any that are available.

The Microsoft Wireless Display Adapter can communicate with devices on either the 2.4GHz or 5GHz wireless frequency bands, but you must have the 2.4GHz band enabled on your device when you’re pairing your device with the adapter.

Note:If you don’t see the Advanced tab, you aren"t logged in as an administrator. If this is the case, select Change Settings, type your administrator password, and select Yes.Then you"ll be able to select Advanced.

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.
