Solved

Hi to all,I am planning a basic STM32 platform PCB for industrial HMI for different customers. At the moment is is not quite clear which microcontroller from STM32F7 or STM32H7 series will be used. It depends on firmware developed by customer. But hardware is (as always) price sensitive and has to be available soon.So my idea is to design the board in such a way that I can choose the STM32 controller that fits the application at assembly time.Is there a document or other information about which STM32F7 or STM32H7 controllers are pin compatible? Is it possible at all to make a pin compatibe layout for STM32F7 and STM32H7 controllers?Thank you for ideas, hints and support Thomas

I am using touchgfx to draw a sine line.I have two questions.This is what I drawed using touchgfx simulator.First question:It looks like somewhere of the line is in light color, I don't konw why? Can it be fixed?This is the drawing using memeory . The CWR using memory is keeping growing.I set the canvas buffer size 32767 which is the largest number.It still is not enough.If I draw some complext line ,it will be a disaster...So the second question:How can I draw line with smallest memory?Best regards for answering. Thanks...

CubeMX ver. 5.3.0. I tried different microcontrollers.

Hi everyone,My name is Chinh, I am working on stm32f030c8t6 for my project. I am using SPI1 to interface with an RF module. This program run very good when I implement on stm32f103c8t6, to save money I decide to switch to stm32f0 which have a lower cost than F1. Unfortunately, I have a big problem that I can't understand and I have ever seen during the working time on stm32 MCU series.I used a pointer (ui8) to point an array and if I change the value of pointer such increasing one by one after every transmission that goes to hardfault handle when putting data to DR register.Examples:uint8_t table[] = {0x06, 0x02, 0x52, x64, 0x01, 0x00};uint8_t rx[10];uint8_t *p;p = table;TransmitReceive(spi, p, rx, 2, timeout);p++;TransmitReceive(spi, p, rx, 2, timeout); -> hardfaultIf I change a bitTransmitReceive(spi, p, rx, 2, timeout);p++;TransmitReceive(spi, p, rx, 1, timeout);-> No hardfaultOr:TransmitReceive(spi, p, rx, 1, timeout);p++;TransmitReceive(spi, p, rx, 1, timeout); -> No

I have made a custom slider , vertical , using pngs .When I run the simulator it does not appear .The default Slider shows but weird refresh and leaves a trail ?Also , is there a way to say which item is on top of the other ? Bring to front , send to back ?

Hello everybody,I am trying to drive ST25T3911B with STM32F072RB. I am using X-NUCLEO-NFC05A1 mounted on the NUCLEO-F072RB.I have configured NUCLEO-F072RB with STM32CUBEMX, you can find the project file attached; for my application I have added CAN connectivity and I2C connectivity.I am using the RFAL library found in the X-CUBE-NFC5, and the application I have written is pretty similar to the polling loop in the STM32F4 example.I am reading ST25TB512-AC tags.The SPI seems to work because my application can retrieve the chip ID from the card, but requesting the UID a hard fault always occures during the receiving phase of the SPI communication.I have noticed that the ST25R3911B continuosly drives the external interrupt even if no card is present, is this correct?Can you check my STM32CUBEMX configuration in order to see if everything related with RFAL middleware is fine?Thank you in advance.Sincerely Alessandro

Hi I am working with LIS2DH12 accelerometer. I want to read and calibrate the raw x,y,z axis data. For the scale level 2g, 4g, 8g, I am getting the accurate readings(At stable position, Z is 1g for above scale levels). But when I change my scale level to 16g, my z-axis is only reading 0.62g value instead of 1g.Here are the register configurations that I am using: /*variables to store values in registers*/ uint8_t value_ctrl_reg1 = 0x47;  // Turn on the sensor, enable X, Y, and Z, Low Power mode, ODR = 100Hz uint8_t value_ctrl_reg2 = 0x00;  uint8_t value_ctrl_reg3 = 0x00;uint8_t value_ctrl_reg4 = 0x88; // FS = ±8g/*Read Accelerometer*/  uint8_t data[6];  #define Scaling_Fac_ACC 2048  vTWI_Read(LIS2DH12_OUT_X_L , &data[0]);  vTWI_Read(LIS2DH12_OUT_X_H , &data[1]);  vTWI_Read(LIS2DH12_OUT_Y_L , &data[2]);  vTWI_Read(LIS2DH12_OUT_Y_H , &data[3]); &nbs

Hi @Martin KJELDSEN​ !This time I'm trying to make a scrollable container containing custom containers I've made. But how do I add the custom container to be a part of the scrollable container in the designer? I can't get the scrollable container to scroll when I first add a scrollable container and then add my custom containers. And I tried making a custom container with a scrollable container, but then I can't add my custom container to my other custom container including the scrollable container. Do you follow? :grinning_face_with_sweat: Do you have any examples using scrollable containers that can inspire me to solve my issue? Preferrably examples I can open in the designer. :smiling_face_with_smiling_eyes: Thankful for answers!

Hello,I read the related wiki page and low power mode document.I can enter low power mode with the command "echo mem > /sys/power/state". Thats great.My M4 program is still running in the background. I am reading a sensor in this program. If it reads above 30 Celcius or the user touches the touch screen, I want the MPU to exit low power mode.What should I exactly do ?With what should I play in m4 code ? tnx

My timer config:  RCC_APB1ENR = RCC_APB1ENR_TIM3EN;  TIM3_CR1 = (uint32_t)(TIM_CR1_CKD_CK_INT | TIM_CR1_CMS_CENTER_3);  TIM3_CR1 &= ~TIM_CR1_UDIS;  TIM3_CR2 &= ~TIM_CR2_CCDS;  TIM3_ARR = (uint32_t)10000;  TIM3_DIER = (uint32_t)(TIM_DIER_CC1DE | TIM_DIER_CC1IE);  PWM_BORDER = (uint32_t)7000;So, timer interrupt is working well only when I null CCR event in the interupt.But transaction interrupt arises at random moments of time. While transacion must takes few SysClk's. May be I have wrong timer config of timer or wrong DMA channel?DMA config:  RCC_AHBENR |= RCC_AHBENR_DMA1EN;  DMA1_CPAR4 = (uint32_t) &GPIOF_BSRR;  DMA1_CMAR4 = (uint32_t) &clockSeq;  DMA1_CNDTR4 = (uint32_t) 4;  uint32_t ccr = DMA_CCR_MINC | DMA_CCR_MSIZE_16BIT | DMA_CCR_PSIZE_16BIT;  ccr |= DMA_CCR_PL_VERY_HIGH | DMA_CCR_DIR | DMA_CCR_CIRC;  ccr |= DMA_

Hi, I'm currently working on STM32MP1.I tried to use STM32CubeProg with STM32MP157A-DK1 in "the Engineering mode", but it doesn't recognize ST-Link for this board. So currently the only option I can program under the Engineering Mode seems to be SW4STM32. STM32CubeProg also seems to be perfect tool for the Engineering Mode (and the Production mode) too.Do you guys have any plan to add support for the MCU part of STM32MP1xx dev boards with STM32CubeProg, or to make any standalone tool?

I am using stm32f205ret. I want to toggle as fast as possible. According to the data sheet i should be able to do it at 60 MHZ. I use cubeMX to initialize my code. I basically set all clocks to max. I set one pin (gpio port C pin 5) as GPIO_OUTPUT. I configure the speed of the port to be high in cubeMX. And keep toggling it in a while(1) loop.I cannot go beyond 1MHZ.I would be really nice if someone can tell what I am missing. I have attached the code for clock setup and gpio setting:static void MX_GPIO_Init(void){ GPIO_InitTypeDef GPIO_InitStruct = {0}; /* GPIO Ports Clock Enable */ __HAL_RCC_GPIOC_CLK_ENABLE(); __HAL_RCC_GPIOA_CLK_ENABLE(); /*Configure GPIO pin Output Level */ HAL_GPIO_WritePin(GPIOC, GPIO_PIN_5, GPIO_PIN_RESET); /*Configure GPIO pin : PC5 */ GPIO_InitStruct.Pin = GPIO_PIN_5; GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;&nbs

Hello,I am using the ST25R3913, following the application note and matching tool to define LC components for EMC filter and matching circuit. Now the function test is quite good, but I have a high pulse at 3rd harmonics (40.8MHz), do you have similar case happens with emission issue?

I want to change splash screen of u-boot with custom image. Therefore I adjusted my image with same properties as default one has. Then I replaced the image under layers/meta-st/meta-st-stm32mp/recipes-bsp/u-boot/u-boot-stm32mp-splash this path with same name " stmicroelectronics.bmp". For applying change I clean the recipe with bitbake -c clean -f u-boot-stm32mp-splash command and then recompile image with bitbake st-image-weston.After completing everything board monitors white screen. I assume I changed something but wrongly.Board: Stm32Mp157c-dk2Best Halil

Hello.I have a DK2 board and I want to wake up MPU (CA7) after shutdown command. If no MCU (CM4) firmware is running then no problems, but otherwise if I run MCU firmware (GPIO example) before shutting down MPU I get the following error after pushing Wake Up button:PANIC at PC : 0x2fff2e81Exception mode=0x00000016 at: 0xc0831f9cAnd it reboots after some time and stops MCU firmware:INFO:   Reset reason (0x214):INFO:     IWDG2 Reset (rst_iwdg2)How can i solve this problem?Thanks.

Hi,I have added the following command to the post build steps.arm-none-eabi-objcopy -O binary "${BuildArtifactFileBaseName}.elf" "${BuildArtifactFileBaseName}.bin"The size of .bin file generated is 393411KB compared to 383KB hex file and does not upload with STM32 Cube Programmer.Has anyone been able to successfully generate a binary file (.bin) to program the STM32WB and how have you done so?Thanks,Daniel

There is a "CubeIDE 1.0 and TouchGFX 4.10.0: Resolving integration issues (1080p) " video presented by Mr Matrin Kjeldsen on the Youtube. It is a very valuable material. It solves the problems, but only with the STM32F746G Discovery board. Analogues problems appear with the STM32F469 and STM32F769 Discovery boards.

We have some legacy TI tags in our ecosystem - (TI RI-I02-112A-03). The M24LR will read them. Our TI reader will READ and WRITE to them, but the M24LR will not WRITE to them. We see a '0000 (03) Option is not supported' message in the ISO15693 UI window.

I have observed, using a frequency counter, that the HSE clock on Nucleo board (after using the calibration value in the OTP memory) is off by around 20ppm. I have configured the SYSCLK to HSE_SYS. Now, HAL_GetTick counts the tick from the derived clock. So, it will go (in ms) off after certain time. right?. Could we correct such error.My application requires precise timekeeping. I see similar issue in the RTC source clock. it's deviated from the actual frequency of 32768Hz. Is there any procedure to correct the deviation.If someone could point to any literature on how to do precise timekeeping in embedded systems considering different latencies and physical errors.

I've been working with I2C on STM32s for some time and I noticed an issue while probing my signals with an oscilloscope.I set my project with CubeMX and usse Atollic TrueStudio as an IDE. Everything works fine. However, I've noticed that the real frequency of I²C is always slightly below the frequency set on CubeMX. I'm using the NucleoF746ZGFor example, if I set the I²C to run at 100 kHz, the real frequency will be around 92 kHz. If I set the I²C to run at 400 kHz, the real frequency would be around 307 kHz, etc.If I'm probing the clock frequency, it's sharp on 8 MHz, as it should be (MCO coming from ST-Link).I was working with STM32F4 before and I dont remember having this issue as I've already probed the signals and it was exactly 100 kHz, 400 kHz or 1 MHz.Is there something I am missing with the clock configuration for this particular peripheral on this MCU ?
