Hello, I want to generate QR code dynamically and also want to clear it sometimes during run time. I got github link and added those files in my project. Still I am not sure how to call it. You have mentioned to call qrCode.setXY(0,0) , qrCode.setQRCode(&code), qrCode.setScale(4) , add(qrCode) methods but I am unable to find it. https://github.com/touchgfx/touchgfx-open-repository/tree/master/widgets/QRCodeCan you please help ?

Hi All,I am using X-CUBE-CRYPTOLIB for AES ECB encryption/decryption on STM32H7 micro and using the F7 example code and library(libSTM32CryptographicV3.0.0_CM7_GCC_ot.a), provided in the crypto package. But the comparison of encrypted message fails with expected cipher text. FYI i have enabled CRC clock. Please help me out to resolve it quickly. Herewith i have attached the code for your reference

In the ref man RM0432 Rev 6 the ADC_CCR have used bits in the lower half.In the file stm32l4r5xx.h from stm32cube_fw_l4_v1151 these bits are not defined.They are defined in the files of MCU of the same familly: stm32l4p5xx.hHave I damaged my files?Are the ADCs different between L4R/L4S and L4P ?

Hello.I haven't found similar question. I am beginner with TOUCHGFX: Is it possible to use TOUCHGFX with STM32F0XX series with some cheap TFT Displays? As I read TOUCHGFX supports all of that drivers but I don't understand how to connect all components together. Is it possible?Thank you!

I keep getting the following failures when I try to run/debug a simple blinky program on my dev board. This is a fresh install of stm32cubeide, new project started with all peripherals NOT set to default settings. Instead I just set pin N3 (GPIOA, Pin 0) to an input and then a pin toggle loop starts when that is activated. I get a "debugger connection lost". Can someone tell me where I'm going wrong?Code snippet from main:while (1) { /* USER CODE END WHILE */   /* USER CODE BEGIN 3 */ if(HAL_GPIO_ReadPin(B_USER_GPIO_Port, B_USER_Pin) == GPIO_PIN_SET) { while(1) { HAL_GPIO_TogglePin(GPIOJ, LD_USER1_Pin); HAL_Delay(500); } } }Code snippet from MX_GPIO_Init()/*Configure GPIO pin : B_USER_Pin */ GPIO_InitStruct.Pin = B_USER_Pin; GPIO_InitStruct.Mode = GPIO_MODE_INPUT; GPIO_InitStruct.Pull = GPIO_NOPULL; HAL_GPIO_Init(B_USER_GPIO_Port, &GPIO_InitStruct);Console output when I run:STMicroelectronics ST-LINK GDB server.

Hi,I'm trying to create a simple TouchGFX Application, that can handle hardware components, such as GPIO. Many tutorials exist but i haven't seen yet an official walkthrough from ST. Maybe, i haven't searched enough. So , is there any tutorial or documentation that explain the right procedure, even the setup for custom hardware design. Further informations : I have an STM32F429I-DISCO. I use STM32CubeIDE 1.1.0 and TouchGFX 4.13.0Thanks

We wanted to use a UART periphal in transfer DMA mode. When configuring it with CubeMX, nothing happens, event when trying it on an empty project.When manually configuring the various registers for DMA transfer between memory and the peripheral data register, the behaviour was correct, so I suspected an issue with the HAL library.I tracked the bug down to the function HAL_DMA_Init in Drivers/STM32F4xx_HAL_Driver/Src/stm32f4xx_hal_dma.c The following line (line 251) is supposed to set the config register for the appropriate DMA stream:hdma->Instance->CR = tmp;But, when step debugging, it appears to have no effect on the register (as seen on the SFRs tab), even if the tmp variable has the correct value... How could this be explained? A weird silicon bug that doesn't allow to set the register in certain state of the mcu? An error in the library?In the meantime, we can just set the DMA stream CR register from the main function.Maybe it's worth mentioning that the issue occured with t

Thank you for helping.I want to display the value detected by the sensor in View.I'm thinking of using the RTOS mail queue.Where should I describe queue reception?Thank you.

Hi, I have followed the AN5247 to implement OTA flow and wondering if it is possible to put different user APP in two flash address and OTA APP could decide to boot from which one. I have tried to flash P2P server_ota in 0x08007000 and HartRate_ota in 0x0802C000(also updated linker info) and update "CFG_APP_START_SECTOR_INDEX" in BLE_Ota as 0x2C to boot from the second APP. Although the HartRate function works, Cube programmer can't even connect to nucleo. It seems something strange. Also because the 2 APPs may be put at one of assigned flash address(07 or 2C), how to handle the linker setting while compile the FW?

Hello everyone, I am a beginner of STM32, how to correctly configure the initialization of STM32H743I EVAL2 touch screen in CUBEIDE, so that ToutchGFX can receive the touch signal.

Hello, I and using Touchgfx in my project. I want to implement below. 1) During run time , I want to to turn off complete screen. 2) During run time , I want to change complete screen. 3) I want to generate QR code dynamically and also want to clear it sometimes during run time. I got github link and added those files in my project. Still I am not sure how to call it. You have mentioned to call qrCode.setXY(0,0) , qrCode.setQRCode(&code), qrCode.setScale(4) , add(qrCode) methods but I am unable to find it.Can any one please help ?

The color setting of the TOUCHGFX control will retreat with one click, which is crazy. I want to manually input the color value. How do I enter it? ? ?

DISCO board for the new 'L4Pxx is out:https://www.st.com/en/evaluation-tools/stm32l4p5g-dk.html?icmp=tt14426_gl_****_mar2020#Remarks:yet another naming scheme, with -DK suffix - bad idea, DISCO was a good keyword to search these at the distributorsno display - okay, although the price is relatively high for the displayless board (probably given by the here unnecessary V3 of STLink, with the bonus of broken 8MHz MCO) - but there's no hint of what the suggested display/board might be, entirely bad move, drowning the DISCO idea furtherSAI audio codec (footprint only), ST-MEMS digital microphone (footprint only) - cm'on, what's the point here?4-Gbyte onboard eMMC, OctoSPI DDR NOR FLASH and PSRAM, - okay, and what for, if there are no IO devices to make use of them?U-suffixed part, with no hint of explanation in the DBno UM yet, although there's a link from the DB - I hope this means ST is hastily removing the amateurish modern-feel-and-look from it, and inserting the schematics.Sorry, ST,

Hello!I try to understand how to exclude some memory from ddr for Linux, but M4 must have to access to that memory, because M4 needs to store about 40 Mb, but not RETRAM or SYSRAM doesn't allow it.

Hi, I need advise regarding my application. I can store historic data using Stream-to-FIFO mode based on single tap interrupt in buffer A. But, I cannot get data after the tap interrupt in buffer B when switching FIFO mode to Streaming mode. I believe I am not configuring the sensor properly to switch from one mode to another. My code is listed below. It collects and store historical data in buffer A and calculates threshold. If threshold is higher, then micro-controller is instructed to switch to the streaming mode and to store data in buffer B. This code returns watermark value 0 for the second part of the code (for buffer B part). It should be 1 for FIFO to output data.S32 get_lsm6ds3_fifo_acceleration_angular_rate_data_s16(S16 *acceleration_mg, S16 *angular_rate_mdps) { uint16_t numA = 0; uint16_t numB = 0; uint16_t num_patternA = 0; uint16_t num_patternB = 0; uint8_t watermA = 0; uint8_t watermB = 0; S32 error; volatile uint16_t acc_magn = 0;   error = lsm6ds3tr_c_fi

RM0440 states in 46.8.3 that SW-DP ID code is 0x1BA01477. However, it's actually 0x2BA01477.

RM0440 Rev 3 (last version) recomend to set 4WS for 170MHz CPU clockRM0440 Rev 2 recomend to set 8WS for 170MHz CPU clockST driver library (STM32G4xx_HAL_Driver) function LL_PLL_ConfigSystemClock_HSE() set 8WS for 170Mhz clock. Which Flash WS setting is right for 170MHz, 4WS or 8WS?
