In the world of embedded systems, efficiency and reliability are paramount, and STM32 microcontrollers from STMicroelectronics have become a popular choice among engineers and developers alike. With a versatile range of features and a wide selection of peripherals, STM32 microcontrollers can handle tasks from simple sensor monitoring to complex industrial automation. However, to fully unlock the potential of these powerful devices, a streamlined development process is essential. That’s where STM32CubeMX and STM32Cube repositories come into play.
Screen flickering refers to a visual issue where the display rapidly turns on and off or fluctuates in brigthness. This can occur intermittenly or continuosly, often caused by hardware problems, outdated drivers, or incompatible software. Common causes include loose display connections, faulty graphic drivers, or incorrect display settings. Flickering may also result from interference by background applications or screen refresh rate mismatches, impacting user experience and possibly leading to eye strain if unresolved.
Programming a QSPI (Quad Serial Peripheral Interface) involves setting up a microcontroller to communicate with a QSPI flash memory device, usually to store or retrieve data at high speeds. Here’s a high-level guide on how to program a QSPI interface:
Riverdi 5-inch HDMI display, which due to the non-standard screen resolution (800×480) on some operating systems, may require additional software configuration.
Purpose of this manual is to show how to program Riverdi HDMI modules with RTDtool.
Before getting started with the instructions, make sure you have the proper software installed.

While most of our products use the uxTouch design, we have noticed a need for the functionality it gives but in the traditional size. So, to meet our clients’ expectations, we have created the aTouch.
Explanation how to fix problem with not working RS485 on STM 5″ boards PCB 50STM32U5 with revison 1.0.
If you are able to do this by yourself then folowing the steps below should help you solve the problem. If you are not sure or you think you could “mess up” something please contact us for further inforamation.
To start with you need to cut the “roads” as shown on the below picture.
One of our aims is to provide you with an easy and efficient way to create your own applications. This is why we are open to all products and tools that you can work with Riverdi products.
You will find a list of compatible solutions below, from GUI building tools, to development boards and compilers – the EVE Screen Designer from Bridgetech, or the Riverdi click from MikroElektronika, to name a few.
The right kind of touch panel can be crucial to the success of your application and product. It needs to match the environment the device is placed in. It also needs to match the type of application it will be used in. That is why our offer is so versatile.
The RiBUS is the perfect BUS for connecting your product with Riverdi intelligent display solutions. It can run with any size or type of Riverdi intelligent display. Once you have it on your device, you don’t need to worry about changing displays mid-project – it just works.
Simple, efficient, and versatile.
We have two screen enhancement options, designed to give your display that special boost and keep it ahead of the competition.
Projected Capacitive Touch Screens are now the most common type of touch screen used in phones, tablets, and other hand-held devices. This is the technology that allows us to tap, scroll, zoom, pinch, and flick, without even thinking about it. It has changed the way we interact with technology and removed previous barriers.
Optical bonding is a process of affixing the touch panel (or only the protective glass) to the display using a liquid, gel, or dry (film) adhesive. In general, this process improves parameters of the optically bonded LCD module – both the optical performance and its durability.
That is what our smart displays are all about. You can easily choose the type of touch panel, mounting frame, or graphics controllers you want, and have the display perfectly fit within your project.
When you’re thinking about the housing and mechanics your display needs, you need to take into consideration in what kind of environment and in what kind of way it’s going to be used.
For example, if you need a TFT display for your smart home application it’s best to choose something that can be easily mounted to the wall so that the user can quickly and efficiently control the temperature and lighting in their home, over the touch panel.
Our mission of building intelligent display solutions means that we also offer the best graphics controllers on the market to run them. The RGB and LVDS modules are a part of our standard offer, but the Bridgetek EVE4 and Solomon graphics controllers and the Hycon family of touch controllers are a great choice if your project requires a more complex execution.
The variety of our display offer is one of the key reasons our customers keep coming back. They can always find the professional solution for thier projects in Rivedi.
Modules with projected capacitive touch panels have a top layer, called a cover. This part of the module is the most often customized component of the product. It’s the part that allows the display to completely change its appearance. To perfectly blend with the rest of your product design.
Antibacterial surface protection is an innovative and effective solution for displays. It’s the next big step in smart display solutions. Kastus is a leading company in this sector and Riverdi is their advanced partner. We offer 24/7 antimicrobial surface protection technology for all Riverdi displays. Kastus designed and patented antimicrobial coatings to protect surfaces against bacteria and germs.

SM in front of any p/n has a meaning only that it stands for single module.
Choosing proper zif connector is mostly dependent on how you place your adaptor board.
Riverdi 5-inch HDMI display, which due to the non-standard screen resolution (800×480) on some operating systems, may require additional software configuration. Below is a brief tutorial.
Changing the level of backlight in EVE modules such as RVT101HVB, RVT70HSB, RVT50HQB is possible by controling the special register responsible for backlight level.
All EVE 1/2/3 modules require the same 20-pin ZIF connector, 0.5mm pitch, down-side.
Compared to the FT80x, the FT81x support displays with higher resolution, portrait orientation option, faster data transfer and image/video loading, and more video memory.
Problem is with EVE4 modules, it concerns situation when the driver connects to the flash memory but does not initialze. Sometimes modules are required to work under different environmental conditions. This error occurs in temperature condition such as 5°C.
To understand Embedded Video Engine (EVE) – BT81x, you have to remember that it doesn’t have typical solution, as it is in embedded systems with LCD screens. What does it mean?
The block diagram shown below applies to STM 5″ modules. They are based on STM32U599NJH6Q or STM32U5A9NJH6Q. The description over connection shows to which pin is each element connected.
Changing the level of backlight in STM modules such as RVT101, RVT70, RVT50 is possible by controling PWM signal.
STM modules, to be precise 5″ ones have 2 types of microcontrollers installed on their boards. One is STM32U599NJH6Q and the other is STM32U5A9NJH6Q.
Most common question regarding this module is if those two microcontrollers are compatible with each other and if it is possible to make project in TouchGFX for each of those modules.
Components from the mainboard duing their operation time gain a little temperature increase. Test based on checking each of the available size of the modules, 5″, 7″ and 10″.
Trying to make a new project in TouchGFX sometimes occurs in below error:
