Hello,I plan to use a STM32H745 controller and 7" LCD TFT display with resistive touch. Am using TouchGFX for UI developement. My application should support Touch gestures such as swipe and list scroll. I already have used capacitive touch in another project with same controller and touchGFX and was able to swipe and scroll seamlessy without any additional implementationAre these gestures possible with a rsistive touch screen? if yes then can you please provide any sample codes for the same.Thanks Anuj  

Hello support team,Have a Nice day.I am working on STM32U585ZIT6 Controller and investigating SBSFU for firmware upgrading.I list our specifications for a custom bootloader below.Enable TrustZoneEnable Dual bankRun time firmware write in the second bankAfter successfully doing it swap bank I do not find specific this series SBSFU related document Can you provide me integration document for STM32U5 Series? https://www.st.com/resource/en/application_note/an5056-integration-guide-for-the-xcubesbsfu-stm32cube-expansion-package-stmicroelectronics.pdfThanksHiren R.

Hello, i am using the STM32H725ZGT6 on a custom layout.As comparison i am also using the STM32H723ZGT6U on a NUCLEO-H723ZG Board.I am using STM32CubeMX, Keil µVision and the ULINK2 debugger.  To test the Serial Wire Flashing procedure, i created an empty Cube Projext (using HSI and no controller pins), compiled itand flashed it to the controller. The Nucleo Board works perfectly fine with this setup. However when i do the exact same procedure (of corse with correct controller), my custom Board has a problem:I can only flash the software when the BOOT0-Pin is set to +3V3 (but not use any peripherals). When the BOOT0-pin is set to GND, i cannot program anymore and there is "SWD Communication Failure" according to Keil. I also tried to toggle a GPIO but had no acces with my custom board so far.Any ideas on this?If you need more infos, please let me know.See Layout files attached. Thanks.

Hi there!If I interpret table 45 on p. 247 of the reference manual correctly, then the IPCC interrupt is not able to wake up a CPU from STOP mode:Am I correct in my interpretation? If so, is there any other way for CPU1 to wake up CPU2 from STOP mode to signal that there is a message waiting? One way I can think of is connecting two GPIO pins so that CPU1 can generate an external interrupt to CPU2 but that feels like such a waste of resources :(Thanks in advance,Pieter

I'm trying to figure out if a latched interrupt affects the INT pin signal. I'm working with Arduino. The datasheet says the following on page 44:AOI-6D = ‘11’ is direction recognition. An interrupt is generated when the orientation isinside a known zone. The interrupt signal remains while the orientation is inside the zone.I understand that latched interrupt makes the IA bit on INTx_SRC stay HIGH until i read the register.But when I enable LIR, this doesn't seem to be true.Before configuring everything, I reset all the registers to default value. I configured INT1 without LIR and INT2 with it to check the difference.I put a LED on each INT pin.Here's the configuration code:write_reg(LIS_ADD, CTRL_REG1, 0x97); // 0x97: 1344 Hz, enable XYZwrite_reg(LIS_ADD, CTRL_REG2, 0x00); // 0x00: HP offwrite_reg(LIS_ADD, CTRL_REG3, 0x40); // 0x40: IA1 on INT1write_reg(LIS_ADD, CTRL_REG4, 0x30); // 0x30: 16gwrite_reg(LIS_ADD, CTRL_REG5, 0x02); // 0x08: LIR_INT1, 0x02: LIR_INT2write_reg

I am facing issues while running a BLDC motor using the 6-step algorithm on the STEVAL-SPIN3201 board. The only modification I have made is to the Hall effect sensor low-pass filter to address noisy input signals.I am encountering the following problems:Current spike on startup: When starting the motor I apply a soft speed ramp, still I get this current spike on the phase current, which sometimes result in 'Over Current' Fault. What can be done to mitigate this? Speed fluctuations: The motor speed fluctuates around the reference speed, resulting in uneven current draw (see "1500rpm_no_load.png"). I have tried adjusting the speed regulator tuning to be less aggressive, but this has not resolved the issue.Current Spikes: Occasional current spikes in the phase currents trigger "Over Current" faults.Do you have any suggestions on how to address these problems?The .stwb6 project is included in the Info.zip file

Hello, Is there any estimation for when the STM32WL3x will be supported in STM32Cube IDE or STM32CubeMX? Also, is there any estimation for when there will be a dev board available on the market? The SoC STM32WL33C8V6TR looks extremely promising for our projects and we would like to start evaluating it as soon as possible. Thank you.

As the title says, the ST "New Products" page lists some products that are not new at all and out of the scope of the timeframe set on the same page.Example:At the point of writing this forum entry, the page, while set to "1 Month", lists the "HCC4049UB" under "Space Products" and the "AVS08CB" under "Thyristors (SCR) and AC Switches".When checking with the waybackmachine, these products have been listed since at least april of 2021! The webpage description and layout implies it lists products that have been released in the selected timeframe, so products like above should certainly not be listed anymore.

If you need an example, how to use PDM microphones (MICs) on STM32 MCU and how to bring the voice/sound via network to a host computer (PC) - here is my project:https://github.com/tjaekel/PortentaH7_VFR_CubeIDE Here is a YouTube video with a demonstration:https://youtu.be/HZ2tHTENgCg it is based on Portenta-H7 (STM32H747) (with breakout board or using the vision shield), but I post it here because: it is NOT based on Arduino drivers, nor Arduino IDE! It is an STM32 Cube HAL based project, for STM32CubeIDE, a regular STM HW/FW project like a NUCLEO board.What it does (it is a pretty heavy/large project):it uses PDM MICs and send it via network (via VBAN): get it via network and route the PDM voice to your laptop speaker, record it with tools (it appears like a sound card interface on PC)it has an UART command interpreter: use commands to enable MIC, to control amplification of MIC etc.it runs a web server where you can also enter commandsit provides a "Pico-C" interpreter: wri

I have the Nucleo-H743ZI2 board. It uses the STM32-H743ZI part which has a reasonably fast 16-bit ADC, or at least that’s how it is specified: https://www.st.com/en/microcontrollers-microprocessors/stm32h743zi.html3× ADCs with 16-bit max. resolution (up to 36 channels, up to 3.6 MSPS)When I am testing this board, running the ADC at about 58ksps in single-ended mode, the actual dynamic range of the ADC seems rather low to me. I have the ADC using DMA to fill a circular buffer. Using a 20-second period sinewave input, I see 2000 counts or more between max to min readings in each set of 4000 readings on what should be a nearly-DC value during that short 70 msec interval, only 0.3% of the sinewave period. Even when I use 8x oversampling to average 8 readings together, and actually connect the ADC input directly to ground, I still see about 120 counts of noise. So considering the full-scale range to peak-to-peak noise, this so-called 16-bit ADC looks to me like it provides less than 10

Hello,I have a project where one of the requirements is to activate the iwdt in some defined circumstances, and refresh it in other circumstances also defined. I need to collect evidence of the correct implementation of iwdt in such a way that the acceptance criteria of these requirements are validated. (And the code can not be modified during the test to put some while(1) that makes iwdt to be triggered, or add some function pointer to a non valid address. The code must be validated as it will be flashed in the product).I had thought to force a hard fault using the STM32CubeProgrammer. Is it possible? Is it possible for example to make the program jump to a not allowed address (e.g. set the PC register to 0x0000000000) to force a hard fault on request to test the iwdt? The idea is to automate the tests, so being able to do it using the cli commands of the STM32CubeProgrammer would be a great help.Thank you very much in advance.

I'm trying to implement a RTC using the LSE crystal of Nucleo-h743zi board (Rev.B model). In addition, I want to backup the timestamp in case of power loss. Following the reference and user manuals, I finally have my RTC worked, using RTC backup registers and a external battery connected to VBAT (unsoldered SB156 and enabled mcu internal charger). So far so good. Unfortunately, after a couple of minutes I realize that RTC loses about 1 or 2 minute. This fault is getting bigger and after 24 hours this fault is about 1hour.I use the RTC as an internal clock and I don't use tamper or wakeup pins. I have also read the errata sheet and I think there is no any conflict or interference with other pins or functions. If I choose to work with the LSI crystal, the aforementioned problem is not occurs. But in that case the backup function doesn't work. It is worth mentioning that the RTC has the same behavior even if I run any of the STM32cube examples pertaining to rtc.Furthermore, I tried to mea

Hello,We are researching the feasibility of a new product and have some questions regarding STMicro's TOF sensors. At this time we are narrowing on the VL53L4CX, but I am sure these questions apply to most of these sensors. The product is detecting distance of a flat, white, square coupon normal to the sensing field. About three inches by three inches. The questions are as follows:1. It seems like ambient light has the most dramatic effect on range of the device. Does it also dramatically effect measurement repeatability and accuracy? As a result, are these sensors generally not used outdoors? Is there a way to compensate for the effect of ambient light?2. The size of the full visual field for these sensors, even with a 18 degree FOV, gets pretty large past several feet. Is there an understanding of how much of the visual field an object needs to take up for it to be detected? For instance, can a 3inch by 3 inch test coupon be detected at 3 meters, neglecting the effect of am
