Hi,I have a custom board project which I have been running for over a year and im looking to add some features to the layout. The screen is a 240x320 layout and the MCU is a STM32H757. I am running touch GFX 4.20 and it will be difficult for me to upgrade from this due to the ties within the cubide and code base.Im looking to add a page with multiple test boxes,as i need to update sensor readings to the screen. Originally i built this in custom containers as i would normally, but it kept crashing on creating on the new page. So i have worked back making the page more and more simple untill i found a threashold of it occuring when i have 38 default text boxes on the screen (see pic), the text boxes have no buffers allocated to them and this is on a fresh screen so no functions or code running.if i lower the number of text boxes to 34 its fine.is this a limitation of 4.20 ?I've tried increasing the canvas buffer and rtos heap and task memory but nothing resolves this crash (HardFault exc

Hi, I am currently implementing software/firmware for the PowerSTEP01 chip and discovered a inconsistency in data sheet https://www.st.com/resource/en/datasheet/powerstep01.pdf. For parameter INT_SPEED (section 11.1.11 in datasheet) the equation does correspond to the stated limits.It says:i.e. steps/s = INT_SPEED × (2^−18) ÷ (250×10^−9)For smallest possible INT_SPEED=1 you get the minimum value: steps/s = 1 × (2^−18) ÷ (250×10^−9) = 15.25For largest possible 14 bit value you get the maximum value: step/s = (2^(14+1)−1) × (2^−18) ÷ (250×10^−9) = 499984.74But according to datasheet equation results should be in range 0 < steps/s < 976.5. So what is correct?NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.

Hello,I having an issue with the LSM6DSL. It's doesn't trigger interruptions on INT1 or INT2.I'm working with the STM32WB10CC and I'm connected through SPI to the LSM6DSL. The SPI is working I'm able to communicate with the sensor but it's not triggering interruptions. Here is what i have already tried :Changing bits PP_OD and H_LACTIVE of CTRL3_C register.Reset memory with BOOT bit of CTRL3_C register.Software reset with SW_RESET bit of CTRL3_C register.Manual triggering of interruptions of both pins PA11(INT2), PA12(INT1) (Interruptions are working)Use another board (same problem)Solder another LSM6DSM (same problem)Use LSM6DSOW (same problem)I can't figure out what is going on.Here is my setup :SPI setup :/** * Function to set LSM6DS SPI communication */ static void LSM6DS_setup_SPI() { /** * Set SPI communication settings */ lsm6ds_ctx.spi_periph.spi_handle.Instance = SPI1; lsm6ds_ctx.spi_periph.spi_handle.Init.Mode = SPI_MODE_MASTER; lsm6

I am currently working with the STM32WB55RGV6 microcontroller, which has a total of 1 MB of Flash memory. However, after generating a project using STM32CubeMX, I noticed that the Flash memory file only indicates 512 KB of available memory.Could you please provide clarification on how the remaining memory is allocated among different sections? Understanding the memory organization would be greatly appreciated.Thank you for your assistance.Thanks and RegardsSarthak Malik

Hi all,I am designing a PCB around the STM32H723 and wants to implement 4 bit SD card communication. As shown in the picture it can be done using 3.3V, with lower speeds, and avoiding these fine-pitch level translators. However does anybody have experience with this towards the STM32H7? 12.5 MB/s is to slow for my application, but 25MB/s should be enough.If there are any sources etc. I would appreciate it!Best regards, EDIT:The STM32H723 also had an internal LDO. Can this one be configured to the SD pins to get 1.8V? Or are external 1.8V level translators needed to achieve SDR25 or SDR50 ... compliant system? 

Hello,Target is power from another source. STlink from USB of laptopI was wondering if the power ON/OFF of STLINK and the target sequencing will damage either the devices? I had one STLINK v2 seems to be damaged while debugging and later it is not able to detect the target, but programmer detects the stlink serial number .. With another STlink I am able to detect the target.

Hello, i have a stm32wb15cci'm trying to make a hold button, that toggles a led on/off when pressed for 2 seconds. my HCLK1 is running at 4Mhz and my prescaler is at 3999, meaning it should count up every 1ms. I'm using TIM1 which is a 16bit timer, so the counter overflows every 65 seconds.the program works as intended for the first 65 seconds, but after that the timer is stuck at 0.static void MX_TIM1_Init(void) { /* USER CODE BEGIN TIM1_Init 0 */ /* USER CODE END TIM1_Init 0 */ TIM_MasterConfigTypeDef sMasterConfig = {0}; /* USER CODE BEGIN TIM1_Init 1 */ /* USER CODE END TIM1_Init 1 */ htim1.Instance = TIM1; htim1.Init.Prescaler = 3999; htim1.Init.CounterMode = TIM_COUNTERMODE_UP; htim1.Init.Period = 65535; htim1.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; htim1.Init.RepetitionCounter = 0; htim1.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE; if (HAL_TIM_OnePulse_Init(&htim1, TIM_OPMODE_SINGLE) != HAL_OK) { Error_Handler(); } sMasterConfig.MasterO

The datasheet suggests load of 20pF .Due to size constraints, I hope to use https://jlcpcb.com/partdetail/318914-CSTNE8M00G550000R0/C341522Most 8Mhz resonators of this size seems to have 33pF

Regarding function calls when performing SPI communication in half-duplex mode.We would like to develop a product that performs SPI communication in half-duplex mode.Are there any sample programs in which the slave side transmits and the master side receives in half-duplex mode?

Dear,Using STM32H0B0, 100 pins version.we wish to sample 1 input with ADC2 at a fixed frequency. This must not deviate and for this we use timer 3 set to the desired sample rate.In the pictures we use 100Khz, but later to go to 1Msps.So the timer 3 is going to trigger the ADC2 to take a sample each time and the results are written to the memory via a circulating DMA. The size of the buffer is currently fixed at 4096 samples. Each time a cycle of 4096 samples is reached it is moved to external memory.The settings of timer 3 are correct and controlled by toggling a GPIO port with the interrupt callback.Now if we apply a sine signal of 5 Khz at a samplerate of 100Khz we would assume that every 20 samples a full sine has been run through.This is not the case in our case. It does this every 6 to 7 samples.So what could we have misconfigured?  

According to the reference circuit, R43 is 75kohm.Also UM2154 User manual said that R43 should be higher than 30kohm.What happens if R43 is 22kohm. Is overcurrent detected by STSPIN32F0?

Hello,What should I do to record BLE traffic (data send and received) between STM32WB55 and PC?

When i measure my distance in 4x4 i don't have any issues at all. But I need to change it to 8x8 for my project.To my knowledge you only need to change the resolution with vl53l5cx_set_resolution() to 8x8 and adjust the frequency accordingly. I have checked if my sensor is measuring with my webcam and it is a solid red light so not blinking or anything. And when i check the output it gives me this: Initializeddata not ready??data not ready??data not ready??data not ready??data not ready??data not ready??data not ready??data not ready??data not ready??Status ranging: 1Error retrieving ranging data on device 0.======== Device 0 ========23, 33, 28, 20, 17, 14, 12, 6,24, 33, 701, 26, 19, 15, 11, 10,21, 31, 32, 25, 21, 17, 13, 12,23, 31, 34, 30, 24, 18, 15, 13,828, 27, 33, 33, 0, 22, 0, 0,0, 0, 0, 0, 0, 0, 0, 0,0, 0, 0, 0, 0, 0, 0, 0,0, 0, 0, 0, 0, 0, 0, 0,BrakingError while checking for data ready on device 0.data not ready??Error while checking for data ready on device 0.data no
