lcd module stm32 made in china

The fakes are probably the most problematic, as those chips pretend to be genuine STM32 parts down to the markings on the IC package, while compatibility with the part they are pretending to be can differ wildly. For the imitations and clones that carry their own markings, things are a bit more fuzzy, as one could reasonably pretend that those companies just so happened to have designed MCUs that purely by coincidence happen to be fully pin- and register compatible with those highly popular competing MCU designs. That would be the sincerest form of flattery.

Earlier this year, Keir Fraser posted an informative summary of some fake STM32F103 ICs as found on so-called ‘Blue Pill’ and similar boards on their Github. The forgeries carry the same marks on the packaging as the genuine STM32 parts, but can often be identified by the pattern of dimples on the packaging, or by the quality of the silkscreen.

These forgeries aren’t always fully functional. As noted by Fraser, many of these parts cannot even be programmed properly, or even run code as simple as the universal ‘blinky’ example. It’s possible that these forgeries are in fact defective STM32F103 dies or similar that are being sold via less-than-legal channels.

More insidious perhaps are the near-forgeries that at first glance may look like the real part, but are betrayed by the identification on them: ‘STM32FEBKC6’. That’s not a legitimate ST parts code, and that should be the first tip. This is another clone that’s likely to bring you nothing but grief, as even when it does work, it is a cut-down version of the STM32F103 design, with missing features. Finding detailed information on it is hard as well.

This leaves the trickiest of the clones, in the form of the aforementioned CS32F103. This clone essentially works like the real deal, and can run Blinky compiled for the STM32F103 just fine. Some of these MCUs may even be marked as the ST part, making them hard to identify conclusively.

Some of these are manufactured by CKS (中科芯微), a Chinese company who have apparently made a feature-complete version of the STM32F103, to the point where they have fixed some of the errata listed in the ST datasheet. An article over at CNXSoft provides some more details on this MCU.

A major difference one will quickly encounter with this chip is when programming it and getting the message "UNEXPECTED idcode: 0x2ba01477". The reason for this is that the STM32F103 MCU reports the ID 0x1ba01477, confusing the programmer. This can be fixed for example in OpenOCD by using a configuration script that specifies either no CPUTAPID (0), or this ID reported by the CS32 MCU.

Probably one of the more famous STM32 clone makers is GigaDevice with their GD32 MCUs. As noted over at SMD Prutser in an article series, the GD32F103 appears to be a faster, more capable version of the STM32F103. It has a higher maximum clock speed and faster Flash storage, with a decapped unit showing that they used two dies inside the package. One for the MCU, and one for the Flash storage, allowing for a rather flexible way to change Flash sizes across their product range.

At first glance the GD32 MCUs look more attractive than the STM32F1 series, with significant increases in clock speed (72 versus 108 MHz) and Flash storage. While the Flash storage on the GD32 should be very slow, being a serial SPI ROM, its use of SRAM on the MCU die to ‘cache’ the Flash storage means that it ends up being much faster than on-die Flash storage, with zero wait states required even at full MCU clock speed.

When it comes to other GD32 devices, however, they seem to be less eager to make direct clones. Their GDF303 MCU kept the same peripherals as the GDF103, even though those of the STM32F3 are arguably better. This also prohibits their use as a drop-in solution for STM32F3xx boards. Depending on one’s opinion of the STM32F1 peripherals, this may also affect one’s decision to use those GD32 MCUs.

Although I was aware of the aforementioned fakes and clones, I nevertheless came across a new one recently. This involved the purchase of some ‘Blue Pill’ STM32F103 boards from a big German importer and reseller of all kinds of Maker tat. I wasn’t proud of this, but I needed some cheap boards to use for BlackMagic probes, and they had a good deal. In the comments for the Amazon listing some people mentioned they got a genuine boards, while others mentioned that it was a ‘fake’.

In the spirit of morbid curiosity, I got a couple of these boards and was both horrified and pleased to see that I had in fact received Blue Pill boards that did not carry the promised STM32F103C8T6 MCU, but instead one marked CH32F103C8T6. On the bright side it did not claim to be an ‘ST’ part.

This CH32F103 MCU is produced by a Chinese company called WCH, with the (Chinese-only) datasheets and reference manual both provided for download. At a cursory glance, both the datasheet and manaul show a chip that’s practically identical to the STM32F103, with identical memory mapping and peripheral registers.

Hooking it up to an ST-Link/V2 dongle and connecting to it with OpenOCD results in the same CPUTAPID error as with the CS32F103 MCU when using the STM32F1xx profile file. After making the same change to the stm32f1xx.cfg file as suggested by others, I was able to flash the ‘Blinky’ example from my Nodate STM32 project onto the board without further issues.

This suggests that at least the basic RCC (reset & clock control), GPIO and SysTick functionality is similar enough for such a basic test to work. Next, I’ll have to explore whether it also handles the USART, DMA, SPI, I2C and I2S functionality the same way as the STM32F103 MCU that I have on a few other boards. If this MCU is anything like the CS32F103 part, the answer is probably ‘yes’.

As for the seller’s response when I contacted them about these Blue Pill boards not featuring the advertised STM32 part, they admitted that they were aware of this and claimed that ‘in two months’ they’d have boards with genuine STM32 parts again. Admittedly that raises a lot more questions than it answers, least of all why they’d knowingly sell boards that do not feature the advertised MCU.

The eagle-eyed among us may have noticed that virtually all of these clones involve ST’s first-generation Cortex-M MCUs (STM32F1 series). Unless you need to buy Blue Pill boards for commercial projects, this is unlikely to do more than seriously annoy hobbyists and others who like to have a stack of $3 Cortex-M3 boards around for random projects. If one orders MCUs and development boards from reputable sellers such as Digikey and Mouser, it’s also unlikely to be much of a concern.

The Blue Pill and Black Pill boards are also seeing a bit of an overhaul recently with updated versions featuring STM32F4-based MCUs. Although a bit more expensive than the STM32F103-based counterparts, they do bring considerably more resources to the table and the much more pleasant (in my opinion) peripherals of the STM32F4 line. These may just make the market for the STM32F103 and with it these countless clones, counterfeits, and copies dry up.

Until the first batches of counterfeit, cloned and copied STM32F401 and STM32F411 MCUs hit the market, naturally. Because that’s apparently the name of the game.

As a 2inch IPS display module with a resolution of 240 * 320, it uses an SPI interface for communication. The LCD has an internal controller with basic functions, which can be used to draw points, lines, circles, and rectangles, and display English, Chinese as well as pictures.

The 2inch LCD uses the PH2.0 8PIN interface, which can be connected to the Raspberry Pi according to the above table: (Please connect according to the pin definition table. The color of the wiring in the picture is for reference only, and the actual color shall prevail.)

The example we provide is based on STM32F103RBT6, and the connection method provided is also the corresponding pin of STM32F103RBT6. If you need to transplant the program, please connect according to the actual pin.

The LCD supports 12-bit, 16-bit, and 18-bit input color formats per pixel, namely RGB444, RGB565, and RGB666 three color formats, this demo uses RGB565 color format, which is also a commonly used RGB format.

For most LCD controllers, the communication mode of the controller can be configured, usually with an 8080 parallel interface, three-wire SPI, four-wire SPI, and other communication methods. This LCD uses a four-wire SPI communication interface, which can greatly save the GPIO port, and the communication speed will be faster.

2. The module_init() function is automatically called in the INIT () initializer on the LCD, but the module_exit() function needs to be called by itself

Python has an image library PIL official library link, it do not need to write code from the logical layer like C, can directly call to the image library for image processing. The following will take 1.54inch LCD as an example, we provide a brief description for the demo.

ST cooperates with Riverdi because we believe that such partnership brings value to our joint customers. On top of this, we also discovered that we shared some business visions about how to make it easier and faster to go from the initial stages of designing a product embedding a graphical user interface to a production ready product. The conclusion was that combining the STM32 High performance microcontrollers, with the free STM32 graphics toolchain and Riverdi displays + PCB and then merge all of this into a board support package ready to run TouchGFX, would be a compelling offering.

Designing and developing a product with an embedded user interface (GUI), can be complex, as it involves many building block and disciplines, which all requires expert knowledge. Riverdi offer is covering a lot of them, allowing the customer to focus on the most important part of the development, the GUI Application itself. And remember that this is the face of your product. Choosing such solution, the customer does not need to worry about sourcing components like the display, microcontrollers, memory, etc. or even writing low-level drivers, development the board support package or porting TouchGFX. Its all ready done. What makes cooperation with Riverdi unique is that Riverdi has been able to drive a 1280*800 display resolution in high colors, with a STM32H7 microcontroller and a TouchGFX application showing a smart home UI. This shows that Riverdi is well aware of how to exploit all the capabilities of the STM32 Graphics offering combining hardware and software in a unique solution. From the first business meetings, it was clear that we shared visions of the market for embedded GUIs. And Riverdi proved that they can go from an idea and concept to actual working hardware, very fast.

LCD, or Liquid Crystal Displays, are great choices for many applications. They aren’t that power-hungry, they are available in monochrome or full-color models, and they are available in all shapes and sizes.

Waveshare actually has several round LCD modules, I chose the 1.28-inch model as it was readily available on Amazon. You could probably perform the same experiments using a different module, although you may require a different driver.

Open the Arduino folder. Inside you’ll find quite a few folders, one for each display size that Waveshare supports. As I’m using the 1.28-inch model, I selected theLCD_1inch28folder.

Once you do that, you can open your Arduino IDE and then navigate to that folder. Inside the folder, there is a sketch file namedLCD_1inch28.inowhich you will want to open.

Unfortunately, Waveshare doesn’t offer documentation for this, but you can gather quite a bit of information by reading theLCD_Driver.cppfile, where the functions are somewhat documented.

Here is the hookup for the ESP32 and the GC9A01 display.  As with most ESP32 hookup diagrams, it is important to use the correct GPIO numbers instead of physical pins. The diagram shows the WROVER, so if you are using a different module you’ll need to consult its documentation to ensure that you hook it up properly.

The GC9A01 LCD module is a 1.28-inch round display that is useful for instrumentation and other similar projects. Today we will learn how to use this display with an Arduino Uno and an ESP32.

I use STM32 to simulate the respirator and stm32f103rct6 to develop it. This module supports serial port or other simple communication interface mode to communicate with TFT LCD screen, and can draw the wave chart in real time.

Here we want to make a project for the medical equipment,ventilator. In this project, we can choose the language and function, and draw the respiratory waveform by the way of random number triggering. When the key is pressed, the MCU detects the pressing signal, and starts to transmit the waveform data to stvc101wt-01 TFT through the serial port The LCD screen uploads the data command, and then the screen will automatically analyze and display it on the screen by using the waveform control. The screen also has the adjustment function, and the voice broadcast function.

That is, the following functions: ① the serial port screen realizes the function of language selection; ② serial port screen realizes the function of sending touch command and switching pictures; ③ Single chip microcomputer realizes the function of data command upload; ④ The serial port screen realizes the real-time waveform display function. After the function is determined, select the module model: ① Stvc101wt-01 is adopted for screen end; ② stm32f103rct6 is adopted for single chip microcomputer; ③ voice broadcast module. Hardware introduction and principle Loudspeaker Because stone serial port screen has audio driver and reserved corresponding interface, the most common magnet speaker, commonly known as loudspeaker, can be used.
