while tryingt o update the CubeIDE , I get the following message indicating that update contains unsigned content Is it safe to install the updates or dose it contains any risk?

Hello, I use the ST25RU3993-EVAL board software. I want to do some Tag settings. Can I use the Generic Command (Tag Settings) to send Commands from the EPC Class 1Gen2 Standard? it is possible, is their any explanation how to enter the Command?

Can some one guild me to get Schematic of STM32H745XI DISCOVERY KIT .We need hardware Schematic of STM32H745XI DISCOVERY KIT to understand EMMC connection and QUAD SPI NOR flash connectionbut there is no systematic provided for the same https://www.st.com/resource/en/user_manual/dm00547983-discovery-kits-with-stm32h745xi-and-stm32h750xb-microcontrollers-stmicroelectronics.pdfFor the Discovery Kit of 747XI systematic is provieded but it has different components than 745XI Discovery Kit https://www.st.com/resource/en/user_manual/dm00504240-discovery-kit-with-stm32h747xi-mcu-stmicroelectronics.pdf

Currently I am using STM32F745I-DISCO board, I am able to design any template and load directly to target board. But My custom hardware has little different LCD driver (ILI9341 2.8inch TFT display with capacitive touch)How to make changes to adapt the new LCD and touch controller ?Is there any way to create the Custom Board in Touch GFX designer to create the project automatically and download similar EVALUATION board ?Is there any example / widget available for GRAPHS ? I need to plot ECG data using TouchGFX, but i could not find any widget related to graph in the designer?

We bought the evaluation board STM32L152D-EVAL. We have just received the board with the version 1.0.1 of the demonstration firmware (october 2015).I would like to download the sources of this demonstration firmware but only the version 1.0.0 is available on st website. Is it possible to get the sources of the demonstration firmware version 1.0.1 ?Thank you

Hello,when generating the code by CubeIDE, the RTC cannot be used with LL drivers in user's application program. It must be used with HAL drivers, since the functions "HW_TS_Init" and others of file "hw_if.h" need "RTC_HandleTypeDef".These functions generated by CubeIDE should also use LL drivers.Best regardsPaul

regarding STM8L001J3 , Should I code directly into the register?No library..?

Hi We have a product in market which uses UPSD3234  controller. Can someone please suggest a controller that can be used to replace this with minimal code changes that supports USB2.0 or above and has more than one UARTEthernet (optional)Thank you.

After downloading the stToolset_pack42 installation package from the official website, it will get stuck when installing to the following steps, resulting in the failure of installation. May I ask how to solve this problem?

Hi, I am working on a MEMS LIS3DSH connected via SPI to a STM32F207ZG having the following configuration:Full scale: 2gOperating mode: 100HzFilter: 800HzRegisters:CTRL_REG3: 0x48 (Interrupt pulsed, active high)CTRL_REG4: 0x6F (BDU enabled, XYZ enabled, 100Hz)CTRL_REG5: 0x00 (BW 800Hz, FS=2g)State machine:Registers:CTRL_REG1: 0x01 (State machine 1 enabled)MASK_1A and MASK_1B : 0xFC (Axes X,Y and Z enabled as input for state machine)TIM1_1 = 0x000ATIM2_1 = 0x0010THRS1_1: 0x55SETT1: 0x81 (peak detection enabled)The state machine is working as expected, after a motion the OUTW command is setting interrupt and the host MCU is reading out values. After S4 expires, state machine is returning to initial state without any additional interrupt.The values are read from the host MCU in following order:PEAK1OUT_XOUT_YOUT_ZOUTS1It is expected, that PEAK1 is holding the highest value detected within the first two states, but it is always having 0 even X,Y,Z and OUTS1 having correct values.What am I d

I am using a custom bootloader in STM32F091RB controller (cortex M0) which has a system clock of 8MHz and my application STM32F091VC controller (cortex M0) has system clock of 48MHz. Will it affect my application peripheral's interrupt. As my interrupts are not working. I have also mapped vector table to SRAM and again remapped it to 0x00000000. Though its not working. Below is from bootloader code.#define SRAM_BASE_ADDR 0x20000000 #define CODE_SLOT_1_BASE_ADDR (uint32_t)0x08002100 #define CODE_SLOT_2_BASE_ADDR (uint32_t)0x08019000   void fnJumpToApp(void) { uint8_t i; uint32_t *p = (uint32_t *)SRAM_BASE_ADDR; // Base of RAM (0xC0 carved out in scatter file) uint32_t *q = (uint32_t *)CODE_SLOT_1_BASE_ADDR; // Base of FLASH __disable_irq(); /* Relocate by software the vector table to the internal SRAM at 0x20000000 ***/ /* Copy the vector table from the Flash (mapped at the base of the application load address 0x08000000) to the base address of the SRAM at 0x20000

Dear friends,I have been using the STM32H743ZI in three phase power supply project and the controller is responsible for the zero crossing detection of the three phases. To do this I use PB0, PB1,PB2 set up as EXTI inputs 0,1,2. Mains frequency is 50Hz and the controller is running at 480MHz set up in CubeMX of course. For now to verify my hardware I have three LEDs connected to PD7,PD8,PD9. While looking at the LEDs I realized that PD7 is not flashing evenly as the other two are doing. I have then verified this on a scope and it is definitely missing interrupt requests. The the other two are performing as expected without missing a single IRQ.After spending some time with this I ended up lowering the core clock frequency and low and behold at about 75MHz all interrupts were reported as expected.Just to clarify the inputs on the GPIOs are 50Hz square waves with slight ringing on the edges. EXTI_LINE_1 and EXTI_LINE_2 perfectly emulates what is happening on PB1 and PB2, but PB0 randomly

In manual UM2369 it states the following:"To set up an STM32MP157C-DK2 Discovery kit as the Edge gateway for your Predictive Maintenance Platform,you can either:• Use a pre-configured image by ST; these can be flashed onto an SD card and run on the Discovery board. Inthis case you can skip the gateway configuration procedure and proceed directly to connecting to thegateway via SSH.– X-LINUX-PREDMNT"I downloaded the appropriate *.imgc file to my HostPC. I also managed to get the STM32Programmer working with DFU and flashed the Starter Package to my Discovery Kit Gateway. The manual or broader website doesn't state how to actually do what UM2369 states in the above paragraph. Anybody have some step-by-step guidance for me?​

Dear ST Hello,I couldn't understand why I couldn't set and reset the PB4 GPIO. I am trying to visualize the GpIO signal using an oscilloscope.I am using CubeMx for this projectI am using this GPIO for CS with SPI3. HAL_GPIO_WritePin(SPI3_CS_GPIO_Port, SPI3_CS_Pin, GPIO_PIN_RESET); status = HAL_SPI_TransmitReceive(&hspi3, (uint8_t*)aTxBuffer, (uint8_t *)aRxBuffer, BUFFERSIZE, 5000); HAL_GPIO_WritePin(SPI3_CS_GPIO_Port, SPI3_CS_Pin, GPIO_PIN_SET);Thank you in advance S.Tarik

Hi ST,I'm trying to enable PWM mode of Timer14 (STM32F030C8T6). But the output is always LOW. I do all the steps described in the ST Periferal Library. Also I successfully run the similar code on STM32F103xxxx. Could you check this simple code? Is there a hardware bug with Tim14 pwm mode?

I've uploaded an Arduino IDE compatible bootloader and I don't want to program it that way any more.

SO i was doing some stm32 research and developed some application now i am going in production phase. Now i wanted to use stm32f765 but there are couple of variants in that series.I am getting confused between this two models STM32F765ZIT6 and STM32F765VIT6 so the basic confusion comes from vddsdmmc and vddusb . this two pins are available in Z series while its not available in V Series. Since sdmmc and usb is supported in both the soc. Then why is it not available on V series . Since i am not getting enough information from reference hardware design regarding vddusb and vddsdmmc. If there is any specific improvement which is vddusb and vddsdmmc is responsible then i want to use Z series other wise i don't want to have any burden on pcb by just increasing pin numbers and i will go ahead with v seriesThank you! Please help

Hello, I am using display TCXD050ABLON (Data sheet Attached) with STM32F746. As per datasheet I did below LTDC setting and still display is flickering badly.Few screen shots of display setting as per datasheet is below.Few Images of flickering display is as below.Any suggestions?

Hello every one; I would like to use lwip with RTOS( In DHCP Mode ). I try use lwip without RTOS ( In DHCP Mode ). It's work but I use lwip with RTOS is not work. I confuse to set priority (NVIC according to FREE RTOS ) lwip with RTOS. Could you please advice me?  Thank you,Best regards.

Hello,I have 3 boards with STM32F205RBT using 2xDAC and 9xADC. Two boards are working just fine but one board has the second DAC output inverted (write 0 ->3V, write 4094 ->0v). The same program is used, boards are the same. The DAC output is amplified with oamp LM324APT. Before the oamp there is 1k current limiting resistor in series and 100k pulldown. The same connection is used with success in several other projects. When I disable the DAC output buffer, the output is no longer inverted. But I would like to keep the output buffer enabled (otherwise is the output voltage not correct...). sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_DISABLE;I expect a HW problem - ESD or something gone wrong in the soldering process...? I have found several more threads with the same problem but there was no solution proposed. The threads are old (2015-2018). Maybe there is a solution now...Can I prevent this problem? If so, how? This board is going into production and I would like to solve it b

I am currently working on a P-NUCLEO_USB002 board to develop a PD solution. It seems the serial debug output is playing up. I set the USB_CLI already but it just give me some garbage data. I double checked the baudrate and it seems ok. Is anyone has any experience on this dev board who can help me with this?
