Solved

I met a strange "problem" with TGFX. Let's say, on one screen, it contains a few buttons and a container. the container is on top of the screen and invisible when the screen is initialized. The problem is when I set the container visible, I found buttons under the container are touchable, even though I cannot see them (the container covers the whole screen). Is this normal? what should I do if I want only the "visible" widgets being "activated". Thanks in advance.

Need help!I am unable to write or read an RFID TAG using the st25ru3993-eval. I'm not finding much information!Can someone help me?

Can anyone provide version 1.4.0 of stm32cube fw F1 ?I'm using Atollic TrueStudio 9.3 to maintain old project,but I can't download that version. My STM32 model is : "stm32f103cb"Full string, as found in .IOC file : "STM32Cube_FW_F1_V1.4.0".Thank you in advance.

HelloI want to write to FLASH variable uint32_t time at power off. Which signal to use for this? greetingsAndrzej

I have a stm32f427 with 1Mx16 external SRAM and SDMMC.I am reading the SDMMC by DMA into the SRAM in two blocks of 512 bytes into a 1024 byte buffer.The SRAM is mapped from 0x64000000 - 0x641fffff. Address and data are not multiplexedI have now discovered that if I set the start of the buffer to 0x64033c98, the 8 bytes from 0x64034000 to 0x64034007 never get updated. Everything else is rock-solid and correct including all the way up to 0x64034097.The processor is clocked at 144 MHz.I set up the FMC with: FMC_Bank1->BTCR[0] &= ~FMC_BCR1_MBKEN; // Bank 1 SRAM 1 enabled by default but we use Bank 1 SRAM 2 FMC_Bank1->BTCR[2] = (FMC_Bank1->BTCR[2] & 0xffe70080) | FMC_BCR2_WREN | FMC_BCR2_MWID_0 * 1 | FMC_BCR2_MBKEN; FMC_Bank1->BTCR[3] = FMC_BTR2_CLKDIV_0 * 1 | FMC_BTR2_DATAST_0 * 2 | FMC_BTR2_ADDHLD_0 * 1 | FMC_BTR2_ADDSET_0 * 1; // reliable at 144 MHzThe fact that the missed bytes are aligned to the FMC address makes me think the problem lies at the FMC end rather tha

I need to send data one byte at a time via SPI. After transferring the byte, I set "Chip Select" from the program to state 1. I track the end of the transfer by the BSY bit in the SPI_SR register. But the microcontroller transmits two bytes, the first byte is the value from the DR register and the second byte 0. The transmission length is set to 8 bits. I tried to set a different transmission length, but the microcontroller always sends two transmissions of the length I set. Below is the initialization code.RCC-> APB2ENR | = RCC_APB2ENR_SPI4EN;// CPHA = 1 // CPOL = 1SPI4-> CR1 =SPI_CR1_BR_1 | SPI_CR1_BR_2 | SPI_CR1_BR_0 | // Baud rate = Fpclk / 256SPI_CR1_MSTR |SPI_CR1_CPOL |SPI_CR1_CPHA |SPI_CR1_SSM |SPI_CR1_SSI;SPI4-> CR2 = SPI_CR2_DS_0 | SPI_CR2_DS_1 | SPI_CR2_DS_2;SPI4-> CR1 | = SPI_CR1_SPE;Send dataLCD_CS_Clr();_delay_us(2); SPI4->DR = data; while((SPI4->SR & SPI_SR_BSY) != 0); _delay_us(2); LCD_CS_Set();_delay_us(2);

Hi,I have a stm32l433 chip and i'm using the internal RC Oszilator HSI.My issue was that code generated straigth from cubemx turned the chip to run too fast, my HalTick was like 1.2 Khz instead of 1kHz. Now i tracked the error down to a bad configuration of the HSI trim registers within the HAL libraries. Followed listed what i've found:RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;This one gets the default value from stm32l433xx.h which says;#if defined(RCC_ICSCR_HSITRIM_6) #define RCC_HSICALIBRATION_DEFAULT 0x40U /*!< Default HSI calibration trimming value 64 on devices other than STM32L47x/STM32L48x */ #else #define RCC_HSICALIBRATION_DEFAULT 0x10U /*!< Default HSI calibration trimming value 16 on STM32L47x/STM32L48x devices */ #endif /* RCC_ICSCR_HSITRIM_6 */Now this RCC_ICSCR_HSITRIM_6 is beeing defined so it takes the 0x40U.So this checks if HSITRIM is 7 bits wide. which is according datasheet correct: Now i see the reset value should be 0x40xx 00x

I’m having some trouble getting u-boot to boot from eMMC. I’ve evaluated my system using the DK2(using SDCARD) and i’m now porting to a custom board. The custom board contains a STM32MP157CAB and a eMCC connected at sdmmc2.My u-boot devicetree(stm32mp157c-cau-mx-u-boot.dtsi) contains the following:aliases { usb0 = &usbotg_hs; mmc0 = &sdmmc2; };The first problem is the eMMC flashlayout file created by the distribution package, it is configured to use MMC1 by default. Is there a way to edit something that the file is created with MCC0 as default?The second problem is with u-boot, it stills want to boot from MMC1:NOTICE: CPU: STM32MP157CAB Rev.B NOTICE: Model: <product name> INFO: Reset reason (0x15): INFO: Power-on Reset (rst_por) INFO: Using EMMC INFO: Instance 2 INFO: Boot used partition fsbl1 NOTICE: BL2: v2.2-r1.0(debug):v2.2-dirty NOTICE: BL2: Built : 13:36:23, Oct 22 2019 INFO: Using crypto library 'stm32_crypto_lib' INFO: BL2: Doing platform setup INFO: RAM: DDR

Hi,I'm currently working on a STM32H753. I'm trying to figure out how an ECC error upon a cache look up is reported. The cortex M7 reference manual doesn't provide much info in that regards with the following text:Each cache can also be configured with ECC. If ECC is implemented and enabled, then the tagsassociated with each line, and data read from the cache are checked whenever a lookup isperformed in the cache and, if possible, the data is corrected before being used in the processor.A full description of ECC error checking and correction is beyond the scope of this document.Contact ARM if you require more information.I'm expecting a bus fault to be reported but I'm not able to find a documentation with that information. I'm waiting for an answer from ARM but is there anything specific to the implementation made by ST that would impact how this fault would be reported ?Kind Regards,David

Hi AlWondering how do you test the infrastructure before delivering it to the application teams?I’m basically referring to the HAL layer , CMSIS and all BSP layer with peripherals.Is there a known methodology for validation tests for these capabilities ?Thanks!

Hello! I am using dark theme on STM32CubeIDE 1.5.1, and FreeRTOS debugging feature. It is a cool feature, but in dark theme FreeRTOS task list is completely unreadable. Light font on white background. What should I do to make font or background darker? Thank you in advance.

Hi to you all!I'm trying to run external mode simulation using:- Matlab R2019b.-CubeMx 5.6.1-Mat\Target 5.6.0-Nucleo F767ZII managed to deploy and run the Simulink model using both Atollic TrueSTUDIO & EAR V8. (generate c code using Simulink and deploy using IDE).The problem is when i'm trying to run in external mode (both by using Monitor&Tune button and Build,Deploy&Start) I get the following error:"Launcher: startApplication(): error with getapplicationexecutable()"Really need your help!thanks!!!George.

Hi all, When ST25RU3993-HPEV, what are the accessories provided along with the EVM could not find the information in the portal. Let us know any where it is specified. Specification and datasheet of antenna used in EVM (Provided along with EVM)

Can you copy screens, objects, and interactions between one TouchGFX project to another? I tried Ctrl + C the objects, but they only seem to copy and paste within the same project window and not from one project window to another.

In our project, it has many screens that have animated container. When the container slides in and covers the whole screen, the widgets beneath the container are still touchable, even though those widgets are "invisible". This does not make sense. Does anybody meet this problem?FYI, we found this problem when the project is almost done, about 50 screens are designed this way. To fix the problem with fewer changes, we created a customed modal window and use it to wrap all the containers. it works, all other widgets are blocked by the modal window. Are we missing something? Any other suggestions? Thanks in advance.

Hello,STM32CubeIDE  1.5.1, latest H7 package for STM32Cube.I have STM32H747-DISC1 board, and STM32CubeMX (in IDE) let me pick max. 36 MHz clock.According to the datasheet STM32H747xI/G datasheet, ADC clock frequency get up to 50 MHz. I overriden frequency on ADC, and it works fine, so I guess this is a bug.

Hi,Is there any pin-to-pin compatible controller available with STM32F072RBTx MCU in ST. Compatible controllers can be with Higher FLASH & RAM size.

How do you change the name of the STM32F4 project that is generated by TouchGFX? I don't see an option to do it in the GUI of TouchGFX because the field for the application name is greyed out: 

I use CUBEIDE 1.3.0 with MCU Package STM32F2 V1.9.0 for Nucleo F207. This package generates a file "stm32f2xx_hal_config.h". In this file, all "USE_HAL_***_REGISTER_CALLBACK" defines are set / not set. What is the proper way to enable these defines? I don't find a switch within the CubeIDE environment. These defines are not in a Begin_user / End-User section. If I enable one, it got overwritten by next time code-generation. Other CPU types like STM32L4 MCU Packages don't generate these defines, I normally set these as global define with the compiler preprocessor settings. With F2xx MCU Package, this does not help. The compiler complains about "redefinition" of these defines. File: stm32f2xx_hal_config.h   #define USE_HAL_SPI_REGISTER_CALLBACKS 0U /* SPI register callback disabled */ #define USE_HAL_TIM_REGISTER_CALLBACKS 0U /* TIM register callback disabled */ #define USE_HAL_UART_REGISTER_CALLBACKS 0U /* UART register callback disabled */ #define USE_HAL_USART_REGISTER_CALLBACKS

hi, I am trying to debug the bootloader which comes with sensortile.box to change it for my requirements. In doing so I want to inspect how it works using debug session. But unfortunately, when starting to debug the session the curser doesn't even recognize the main.c func. how to debug a bootloader successfully. I tried with user applications and I can debug...

Hi,I am looking for the example from the picture below.To save time, I want to reuse the graphics in my application (I guess those graphics are free of use).Thanks!

Dear All,I have tried to make the slide transition effect when a screen is changed to another screen. I set all "Interactions" in TouchGFX designer.Change screenTransition : SlideTransition Direction : Eastother setting are all good.But the screen transition act like "None" transition option."Cover" transition option ==> it works. "Slide" transition option ==> it acts like "None"But one thing, the simulator works fine for evey options.Why "Slide" transition option doen't work? Please give me some advises about this matter.Thanks in advance.FYI, I don't use GFXmmu and I use DMA2D.
