Solved

I just received an STM32L4P5 Discovery board to evaluate eMMC for the STM32L4. In the firmware package for the STM32L4 there is an example project, "FatFs_eMMC_Standalone". I have built the example, however, when I try to run it the application halts in "initialize_monitor_handles". (SIGTRAP Trace/Breakpoint Trap)Seems there is perhaps an option missing in the project, can anyone help me to resolve this please.

I can't reach the site to download open stm32 system workbench. My emergency!

Hi!.I'm developing an Android app to read and write info into ST25DV64K.For the moment, I'm using the folowing functions of ST25SDK: com.st.st25sdk.NFCTag readBytes() and writeBytes() and they work properly.Now, I need to protect the reading and writting in ST25DV64K with password and I need to know which ST25SDK functions I can use.If possible, I would like to have a piece of code where I can see how the functions work.Thanks in advance!.

When i open an example project everything works OK. When i create a project using CUBEMX or the IDE i see a limited number of drivers. Working with STM32F411RE. I don't see any LL Drivers.

using Nuleo-401RE EVAL and x-cube-spn3-Stepper Motor sample project for expansion board. want to use UART2 and change FLAG pin to PA0. In STM32 Cube IDE I am not able edit back the pin configuration (.ioc not visible in sample project), how to change or re-assign the pins and re-generate code, need to go back Cube Mx? or can we do with Cube IDE we can modify pin assignement?

I haven't looked at the forum for a few weeks but just noticed that my full name is being displayed in a question I just posted, rather than my nickname.I would prefer that my nickname were displayed instead - could we revert to doing that please?Also, when I look at my profile, I can't find how to change my real name anywhere, although I can see where to change my nickname. Is it possible to modify my real name?

Hello everyone,I am using STM32L4R9AII with my custom board. When i start to develop my project, cubemx didn't support my MCU. So, I got discovery board project from Touchgfx and changed a lots of things to adapt it to my custom board.Now cubemx supports my MCU. I started to pass my project to cubemx project. My screen resolution is 400x400px via MIPI dsi. When i established my project from cubemx, it didnt work well. I put a box on screen, i could see the box color but every lines were different places. I digged down deep:I passed display width as 400px to cubemx. So, Touchgfx passed BlitOp.nSteps=400 to DMA2D.But GFXMMU module knows evey line has 1024px, but display is 400px. BlitOp.nSteps must be 1024. When i check my old project and discovery board project from new version of cubemx, i found code below to fix it:#define BSP_LCD_IMAGE_WIDTH (3072 / 2) #ifndef GUI_FRAME_BUFFER_WIDTH #define GUI_FRAME_BUFFER_WIDTH BSP_LCD_IMAGE_WIDTH   void TouchGFXHAL::setFrameBufferStartAddress

In my code when I am using touchgfx::Unicode::UnicodeChar it is showing expected an expression....What files should I include to solve this error

Hi!   As the TouchGFX library is free for STM32, will it also support the STM32MP1 running under Linux?   Regards Friedl

I'm using the STM32H743 and the it will not allow me to choose fast mode for a 400kHz clock speed. Is that a bug in the IDE?

Thank you for helping.environment:MCU: STM32F769BIProgrammer: stm32CubeProgrammer Ver2.6.0I booted with the BOOT pin of the MCU set to H level and tried to write the hex file by the boot loader using USART1.It's progressing halfway, but I always get an error and the write fails.What is the cause?Attach the log file.Thank you.

I'm using a ToughGFX Designer with STM32H7B3I-DK and when I hit "Run Target" it runs but then stops with the error below.

I have downloaded STSW-ST25RFAL003:https://my.st.com/content/my_st_com/en/products/embedded-software/st25-nfc-rfid-software/stsw-st25rfal003.license=1586083459059.product=STSW-ST25RFAL003.version=2.1.2.htmlBut I cannot find example code of how to use, like the examples provided by for example ST Hal library examples.I want to activate RFID reader, read RFID tag and the but RFID reader in sleep mode and after a while repeat.

Hi, I'm trying to load my Keras model (built for CamVid dataset) into STM tool, but when I try to analyze even with compression set to 8 it gives me the "Required Ram or flash size for network is bigger than available Ram or Flash" alert.I tried to modify my model also trying to eliminate various layers, but nothing.the model is:and this is what I have after the analyze:any idea? thank you!!

Hello,I am using NEO M8U as GPS sensor in our custom board.GPS data is has to be collected using UART6 of MCU(STM32F411VEH6). Signal names in schematics as (MCU_GNSS_UART_TX and MCU_GNSS_UART_RX).Code has been attached . I am unable to receive data. I am suspecting some configuration issue of UART6.Kindly suggest.Regards,GBiswal

If I want to take multiple readings on a VL53L1X at different ROI's, I need to set the optical centers for each ROI sequentially, one for each measurement.But when exactly do I do that, and what are the pitfalls?e.g. I have a timing budget of 20ms, and an inter-measurement period of 25ms (so 5ms gap between measurements).Then I start ranging on the sensor. Is the first sample wasted? Can I set the ROI before I start ranging?Can I only set the ROI after ranging has started, in the time-budget (actually measurement) phase?Can I only set the ROI after ranging, but in the same inter-measurement period? (the 5ms window in my example)?If I can set the ROI in either phase, what are the safety time budgets? (i.e. how close can I get to the ends of the time-window)Thanks!

Your microcontroller STM32 L562RET6 claims NIST SP800-90B conformity.Does this TRNG also fit the criteria of the functionality class PTG.2 in the document "A proposal for: Functionality classes for random number generators" [1]Is the TRNG also comform to the AIS31 standard?[1] https://www.bsi.bund.de/SharedDocs/Downloads/DE/BSI/Zertifizierung/Interpretationen/AIS_31_Functionality_classes_for_random_number_generators_e.pdf?__blob=publicationFile&v=1

Hi,I am not quite sure about this. I have a STM32L100 µC operating at 1.8V, the analog pin sees a 3.0V coming from a battery and I want to use the ADC to be able to monitor the voltage of the battery.I plan to supply the VDDA Pin with 3.3V (the VRef+ is internally connected to VDDA).My question: Is this allowed. Can I give the VDDA a different voltage than what the µC is operating with?I read the datasheet but i did not quite see the relation between VDD and VDDA.

STM32G0-DISCO and Power Analyser UCPD Software. I cannot see the STM32G0 disco device when attached through the micro-USB. Tried all the obvious things: Restarted, Firmware updated/reflashed, STLINK updated, tried Windows/OSX.The board/port will not show in the application. LCD works ok, can step through the menus, etc.So what is the one thing I did not do?

Hi,I am able to try FFT analysis with 6KHz. I have also tried the MLC applications on ISM330DHCX separately. Is it possible to run the both applications simultaneously. Since, My FFT runs at different ODR and occupy the FIFO until the process is done. MLC runs at different ODR. How can we run both FFT and MLC.
