I have implemented a TextArea without wildcards to display fixed Chinese content. I have now created a TextArea with wildcards and want to dynamically display any Chinese content in the TextArea buffer. But so far all that has shown is "??? ". How to operate, thank you

hi all.I use touchGFX with FreeRTOS.My other Task is working fine. However, A few minutes after the system starts, the touchGFX task is blocked and will not run. This phenomenon occurs more quickly when the 16-bit control is performed than when the external RAM data line is 32-bit.I'm not sure what I'm going to review. What should I check?​

Hello,I have a display issue when I using the wildcard buffer.I already used wildcard buffer by the past on a previous version of touch GFX.I created a new project for a custom board and the problem is that I can't modify a text with the wildcard buffer. See my function below : void Screen1View::Button1clicked() { Unicode::snprintf(textArea1Buffer, TEXTAREA1_SIZE, "Bonjour"); textArea1.resizeToCurrentText(); textArea1.invalidate(); }On the screen the letters (B,o,n,j,o,u and r) seems to be all on the top of the others, all at the same position.I made some tests and in another one, I obtained only few letters of the complete word "njo" for exemple. I think I use touch GFX function as needed because as I said I already complete an application on a previous custom board. The only one difference is that on the previous project I used IAR and for this new one I use Atollic.I also tried to complete the buffer, char by char : textArea1Buffer[0] = 'B'; textArea

I'm working on a project that involves NFC communications, so I bought the two product listed in the title to start prototyping. The first step in my plan was to get some sample code running, so I downloaded the X-CUBE-NFC5 package. However, it's unclear to me how to import the source code into a project. I'm using the STM32CubeIDE. Since I'm not using one of the Nucleo dev boards with a pre-built binary, I can't just flash a .bin file, but even if I was, I would still need the example code working to base my application off of.So far, I've tried bringing in source and header files one folder at a time to resolve "file/path not found" errors on "include" lines. It's a slow process, but after fixing a few typos and mysterious errors, I ran into an issue I can't fix: the assembly (*.s) files in the Startup folder are written in the armasm syntax, but the arm-none-eabi-gcc assembler only accepts GNU syntax, so each line comes up as an error (including comments). I tried transplanting a st

Hi!I have a question. I know that the question is similar to https://community.st.com/s/question/0D50X0000APcm2T/stm32cubemx510-adc-dma-continuous-requests-doesnt-workBut I have heard that this bug was fixed in CubeMX 5.2.0. I'm using CubeMX 5.3.0 with Nucleo STM32F446RE board and this I want I get when I start a new project.As you see, "Disable" is only selectable option here. Why? Here is the data sheet:https://www.st.com/content/ccc/resource/technical/document/reference_manual/4d/ed/bc/89/b5/70/40/dc/DM00135183.pdf/files/DM00135183.pdf/jcr:content/translations/en.DM00135183.pdfHave a look at this picture. DMA is available.

Hi, I'd appreciate it if you could answer a few questions.I try to use HAL_CAN_Recive_IT in the HAL example, but it's not automatically set up in CUBEMX. Why? And how do I use the HAL command in TRUESTUDIO?

Today I decided to start a fresh project on my NUCLEO-F429ZI board. As I tried to select the board, I was notified that that board is obsolete, and CubeMX won't generate code for it. Soon, I found that all boards are marked obsolete! So I am pretty sure it is a bug. But that means I can't proceed with my work unless I am willing to spend time on finding and setting up the old working version - if at all it is still available for download. and then merge my code to the latest CubeMX generated code when the bug is fixed. This is a lot of extra work.There should be more stringent testing done on software before releasing it. This is not the first instance of ST's software creating trouble. I do understand presence minor bugs. But the kind of bugs I come across with ST give an impression that the software development processes are far from mature.Examples:When you make some changes in the .ioc file and regenerate the code, once in a while it says firmware not available in repository even t

I've been having trouble with the GPIO BSRR/BRR registers for the part i'm emulating in Keil, as the setting of bits in these registers aren't having any affect on the ODR register.I've been trying to just have a loop toggle the state of a pin, which should be writing to BSRR/BRR registers for that port to set and reset that pin respectively.However, when monitoring the state of the ODR bit for this pin, it isn't being toggled.Code Snippet as follows:while (1){ HAL_GPIO_TogglePin(RST_OUT_N_GPIO_Port, RST_OUT_N_Pin); }// And the HAL function call:void HAL_GPIO_TogglePin(GPIO_TypeDef *GPIOx, uint16_t GPIO_Pin){  /* Check the parameters */  assert_param(IS_GPIO_PIN(GPIO_Pin));   if ((GPIOx->ODR & GPIO_Pin) != 0x00u)   {    GPIOx->BRR = (uint32_t)GPIO_Pin;   }  else   {    GPIOx->BSRR = (uint32_t)GPIO_Pin;   }}-------------------------------------------------------------------------I

Yesterday my cubeide is working well. But today when i want to configure project with default peripheral but all board display warning  The target device 'STM32XXXX-***"is currently not supported by STM32CubeIDE according 'Obsolete' marketing status The target device 'STM32F072B-DISCO' is currently not supported by STM32CubeIDE according 'Obsolete' marketing statusi tried uninstall cubeide and install again but this problem cant fix. anyone help me fix this problem. Tks

I just wanted to create a new project for the board ( last project I created about 24 hours ago, was still working ). That caused an update to run, the device is now obsolete, and I can't create projects, get the error: The target device 'STM32F429I-DISC1' is currently not supported by STM32CubeIDE according 'Obsolete' marketing statusAs of now, the status on https://www.st.com/en/evaluation-tools/32f429idiscovery.html is still ACTIVE. What is that, and how can it be fixed urgently?

I was thinking that it would really useful if there was a ready to use Raspberry-Pi computing module look alike STM32MP board which could be used in development of user applications.The reason is because although ST has designed MP series to be optimized for 4Layer PCBs, the cost of 4 Layer PCB manufactoring yet is much higher than 2Layer ones. And also most of the times the PCB layout for MCUs and MPUs must remain the same around the chip. So why not provide a pre-made module for prototyping? and also if with a resonable price for productionThe module could contain an MPU + SDRAM + Flash and all the side requirements. It would bring out all the GPIOs out with probably 2mm or 1.27mm header pins (and not like RPi way which requires a DIMM socket which is not so common and usual)

I'm using a Nucleo-H743ZI2 to learn more about the H7 architecture in preparation for a project. I'm using the latest STM32CubeIDE with the 1.5.0 firmware, but I also tried (with no difference) STM32CubeMX.I very much prefer the LL libraries to the HAL, so after having built a test app with HAL, I went into the Project Manager, Advanced Settings page of the configurator, to select LL libraries instead of HAL. To my surprise, only the GPIO LL library was selectable, and there was no way to set LL libraries for RCC, ADC or USART. I can see that LL libraries are provided (and documented) in the firmware, and the few LL examples for my board have the code to initialize the RCC, so clearly I could make the LL to work, but I would lose the ability to use the configurator.Why are the LL libraries for H7 provided but not usable from STM32CubeIDE?EDIT: I tried again using my STM32F407VGT6 board, and as expected I could configure RCC, ADC, DMA and USART using the configurator and LL libraries, e

Hello, I am new about MQTT, so I am looking for an example of Mqtt client application using the LWIP MQTT api over STM3210c board with no Rtos support .Can someone help me?

Is there any specific address location in generated binary file so we can know the size of that binary file?Using this, in the firmware to read the size of binary file from that location and use it in our application.

Hello.I've created basic image with FlashLayout_sdcard_stm32mp157c-dk2-basic.tsv from stm32mp1-openstlinux-4.19-thud-mp1-19-02-20 downloaded from site. And I can't normally enter to any low power mode: stop - "systemctl suspend" or "echo mem > /sys/power/state", standby - "shutdown now". It always resets itself after some time (seems like it's IWDG). But I don't have such problems with 'trusted' image.How can I fix it?

To use the VL53L1X with a 3V3 supply, I will have to select 2V8 mode.The default mode is 1V8 mode. The selection wil be done in 1V8 mode. Apperently I2C will function correct in 1V8 mode with a 3V3 supply.What is the difference between 1V8 and 2V8 mode?

I use STM32 Nucleo f429zi. I tried to replicate the application on the following link, and followed all the steps. I use USART3 with pins PD8 and PD9 (the manual says these pins are connected to ST-Link)https://www.youtube.com/watch?v=grgNXdkmzzQI use STM Cube IDE. On STM Cude IDE -> there is Debug option to flash the code on Board. However, when I try to Debug - there are errors generated in the app_x-cube-ai.c file.void MX_X_CUBE_AI_Process(void) { aiValidationProcess(); /* USER CODE BEGIN 1 */ int nb_run = 20; int res;   /* Example of definition of the buffers to store the tensor input/output */ /* type is dependent of the expected format */ AI_ALIGNED(4) static ai_i8 in_data[AI_IMAGECLASSIFICATION_IN_1_SIZE_BYTES];   AI_ALIGNED(4) static ai_i8 out_data[AI_IMAGECLASSIFICATION_OUT_1_SIZE_BYTES];   /* Retrieve format/type of the first input tensor - index 0 */ const ai_buffer_format fmt_ = AI_BUFFER_FORMAT(&ai_input[0]); // ai_input undeclared const

I'm experimenting the example SPC560Pxx_RLA PIT Test Application for Discovery.It is simply a 3 led flashing using PIT.Is it possible that the frequency of the example is wrong? It is exactly doubled, instead of 4,2,1 Hzi read 2,1, 0,5 Hz.The quartz on the board is exactly 12 MHz.
