Description: The μLCD43(GFX) is an intelligent graphics display that harnesses the power of Active Matrix LCD (TFT) technology to deliver a diverse range of features in a single, compact cost effective unit. Embedded at the heart of the design is the PICASO-GFX2 processor.

The PICASO-GFX2 belongs to a family of processors powered by a highly optimised soft core virtual  engine,  E.V.E.  (Extensible Virtual Engine). EVE is a proprietary, high performance virtual processor with an extensive byte-code instruction set optimised to execute compiled 4DGL programs. 4DGL (4D Graphics Language) was specifically developed from ground up for the EVE engine core. It is a high level language which is easy to learn and simple to understand yet powerful  enough to tackle many embedded graphics applications.

4DGL allows the developer to write applications in a high level syntax similar to popular languages such as BASIC, C and Pascal and run it directly on the PICASO-GFX2 processor embedded in the uLCD-43 module. It allows the user to take complete control of all available resources on that hardware platform such as the Serial Ports, Graphics LCD Display, uSD memory card, I/O pins, etc. This eliminates the need for an external host controller/processor to drive the uLCD-43 module via serial commands. It provides the user complete control over the hardware module allowing them to quickly develop powerful applications.

Note: The module can be switched to a "SGC" by changing the firmware. It's been brought to our attention that trying to program the 4D screens using an FTDI breakout can damage the driver. You'll need to use the FT232RQ USB to Serial which you can find in the related items below.

  • This is a great screen, but missing a KEY requirement for me. Are you planning on carrying the uLCD-43PCT(GFX) version that has Capacitive Touch built in? Resistive Touch is so 2005.

    • Still no Capacitive touch at SparkFun?

    • Absolutely, the uLCD43 with cap touch is due for release late February.

      • Will the Capacitive Touch model still be available this month?

        • And will it carry a higher price tag .. I just ordered the resistive touch from another site and I’m really going to regret it if the capacitive is the same price.

          • I have an email from 4D Systems saying the following: The uLCD-43PCT with cap touch is yet to be released, we expect to go live by Mid March with an MSRP of USD249.

  • You say: “Note: The module can be switched to a "SGC” by changing the firmware. It’s been brought to our attention that trying to program the 4D screens using an FTDI breakout can damage the driver. You’ll need to use the FT232RQ USB to Serial which you can find in the related items below."

    What is SGC and why would I want to use that ? Also any word on the Capacitive touch version ?

    • Ignore SGC if you are new to 4D Systems. SGC was the legacy Serial platform, which has now been replaced.

      Capacitive Touch is available however not from Sparkfun. Available for the 4D Systems website online store.

      This product has been around for a number of years and has evolved over the years in both hardware and software. Please refer to the 4D Systems website for up to date information, however purchase from Sparkfun.

  • Well shipping from 4D is $32 and it’s overseas which might explain part of the price.

  • Kind of odd this screen is $140. While 4DSystems sell it for $99. Good screen, will buy one real soon

  • Can anyone report on the performance of the serial commands? I have a device from another company with a similar serial protocol, but it turns out that drawing one pixel (or “line to”) is taking ~10ms! I want to show a real-time graph, but, at that rate, a simple 128 line-segment graph is taking over a second to render. I want to update the graph at minimally ~4 fps, though I’d prefer ~30 fps. Can this display do that? (Or, if not, can you point me at one that can?)

  • The datasheet appears to mention extreme brightness (I interpret 4600-5000 nits). This would be perfect for me (mounting it in the dashboard of a glider), but it is about 5 times as much as I usually see for displays. How well is this display readable in the sun?

  • Is there a way to implement ActiveX indicators into the Workshop software?

  • Bottom left corner of the last picture: “Warrenty void if removed.” I hope that “4D Systems” knows who is buying these…

  • How would I go about using a salvaged 7.3" TFT with a touch screen. Is there a controller breakout I can use?

  • Is there a BEZEL available for this? Thanks.

  • If you are interested in this display and/or have used 4D displays in the past, you should wander over to their site. They have a new version of their IDE which incorporates a visual aspect to your layout making it at least a little more like the Mac XCode IDE.

    One of the great features of the upcoming Capacitive touch version is that there is a keyboard option with multiple versions including a full qwerty keyboard pre-programmed and ready to go. The only drawback is that you must use the GFX version of the firmware since the new features are not supported by SGC yet. I cannot wait!

  • Do you have a date when the Capacitive Touch model will be available?

  • A few questions for 4D Systems (and maybe Sparkfun):

    • Will 4D make a 640x480 4" display?

    • Will 4D send some P1-EB’s to Sparkfun? I have the uOLED-3202X-P1 and want faster access to it!!!

  • I want one!

  • Noob question…

    After reading the documentation and visiting the manufacturers website I noticed their warranty states that it will be voided if any serial to USB converter cable other then the one they supply is used. Is there a reason for this? Also where can I get said cable without ordering from Australia.

    Thanks!

    • We discovered that not all USB cables and USB->serial converters exhibit the same characteristics. Some USB cables dropped the VBUS down to 4.3V instead of the nominal +5V. Some USB cables have thinner wires inside and hence cannot carry the supposed 500mA and some cheap USB-UART converters uses bad RS-232 chips and drain more currents.

      So if the device is sensitive to the +5 VBUS and/or other reasons, the data may be corrupted and hence produced weird results. I don’t know if 4Dsystems has this problem but our own products certainly had issues with these sorts of problems.

    • You can use the uUSB-MB5 for programming the uLCD43, this won’t void the warranty.

      • And how can you “tell” that a 3rd party adapter has been used?

        Why not make a approved list of adapters?

        • 4D Systems recommends any one of the following USB to Serial Converters to program their display modules uUSB-MB5 and uUSB-CE5 These USB to Serial converters have special circuitry that uses the DTR line to generate a Reset signal which is part of the PmmC/4DGL programming protocol as well as our extensive range of software test tools. Third party USB to Serial converters do not provide this reset circuity and in the past users have attempted modifications and could not make it work or have corrupted the internal chip PmmC loader. Others have connected the DTR signal from 3rd party converters directly to the Reset pin and some have attempted to manually simulate the reset pulse, most of these attempts proved to be futile and have caused considerable tech support headaches.

        • I strongly recommend using one of 4D Systems cable to prevent any damage.

          The programming cable comes with drivers for Windows, Mac OS X and Linux.

  • This screen is just great, with extra real estate compared with the uLCD32.

    The Serial_LCD library I wrote for the uLCD32 can handle now the uLCD43, as well as Goldelox-based uOLED screens.

    Have fun!
