I try to make an application with STM32H745I_DISCO. After I enable TouchGFX, and generate code, the project fails to compile.Did ST started supporting TouchGFX officially on STM32H745I controllers ?Is there any official documentation/guidelines ?If anyone is successful in doing the same, please share a demo project with CubeIDE. I don't have access to any other compiler.

Hello Newbie question here, so i was working for with the stm32mp157 for quite a while now .the boot process for me was flashing an SD Card or a USB stick and boot the thing up. How ever i was wondering if there is a method to load openstlinux or just u-boot into RAM and Un-mount the disk or something and the Linux will keep working like with Ubuntu (Boot to Ram) ? if so how to do it ? Thank you

I have the imu 10dof and i got raw data of accelerometer, gyroscope and magnetic. And i calculate the roll, pitch, yaw base on equation same in picture. i had calibrate accelerometer and magnetic. in the picture, show the data of magnetic before and after calibrate. But the yaw angle is not linear. I rotate the imu from 0 to 30 degree but yaw data is 0 - 5 degree, rotate the imu from 30 to 60 degree but yaw data is 5 - 15 degree, rotate the imu from 60 to 90 degree but yaw data is 70 - 115 degree.my english is not good, please help me.thanks!

I have got a custom PCB using STM32F4. I don't have any capacitor connected to the VCAP Pin and I wonder if this is necessary or not. Which is the use of VCAP and do I need to add it to my design? What can I do to solve my problem of no having one if necessary (I supose it is not a good practice to place one in a bad way due to EMIs and bad behaviour of the capacitor in general)?Thank you.

We use Rfal library for ST53L1X application. In demoNfcv(), the write and read is ok, when using rfalNfcvPollerWriteSingleBlock().For testing multiple blocks writing performanace, we modified the program as code attached.with rfalNfcvPollerWriteMultipleBlocks, no data were written to tag. There is no change in tag blocks. Coould you givie any hits for this issure?best regardsDai Sai

The STM32 Selection Guide 2021 Shows that STM32F407VET6 contains 512K flash, but actually the flash could be wroten from address 0x0800 0000 to the 0x080F FFFF, So what's the problem?! 

I want to pass the some parameters to kernel command line. drm.edid_firmware=edid/1280x800.binI tried to use "bootargs" environment of uboot. env set bootargs "drm.edid_firmware=edid/1280x800.bin"But, Not working as I expect. I couldn't find my parameter in kernel command line. below is dmesg log.Kernel command line: root=PARTUUID=491f6117-415d-4f53-88c9-6e0de54deac6 rootwait rw console=ttySTM0,115200below is /proc/cmdline log. root@stm32mp15:~# cat /proc/cmdline root=PARTUUID=491f6117-415d-4f53-88c9-6e0de54deac6 rootwait rw console=ttySTM0,115200How to pass the kernel command line parameters on uboot?thanks in advance.

Dear Community,I would like to request manufacturing additional board for a project but currently PCB assembling partner doesn't have STM32F407ZET6 in stock but it has STM32F407ZGT6.Basically, these two MCUs have the same capabilities except ZGT6 has double amount of flash memory which I don't need to use.Should I afraid loading the same software in ZGT6 would cause problems?So I would only use 512kB of flash but I would like to download the same firmware.It is because I have an own boot loader and remote upgrade possibility and I would not like to handle two separate chips for remote upgrade because of the inability to source the very same chip.Theoretically they should not have more difference other than their flash size.Do anyone have any experiences or ideas?Also, would development environment (STM32CUBEIDE) allow programming a ZET6 project into a ZGT6 chip?Thank you your help in advance.

Hello everyone ~Below link is my last question about display quality of dual screen. Fortunately I solved it but I faced other problem. https://community.st.com/s/question/0D53W00001mHWaWSAW/stm32mp1-can-i-duplicate-ltdcrgb-signal-for-dual-displayAs I mentioned in the above question, I want to implement dual screen that display same contents same time.My TFT-LCD's resolution is 1280x800 (10.1inch).so HDMI also has to has 1280x800 same resolution with LCD. The monitor or TV that support 1280x800 resolution in EDID display well both all.Below is "modetest" log when work fine.root@stm32mp15-prox:~# modetest -M stm -c Connectors: id encoder status name size (mm) modes encoders 33 32 connected HDMI-A-1 480x270 1 32 modes: index name refresh (Hz) hdisp hss hse htot vdisp vss vse vtot) #0 1280x800 59.91 1280 1328 1360 1440 800 803 809 823 71000 flags: phsync, nvsync; type: driver props: 1 EDID: flags: immutable blob blobs:   value: 00ffffffffffff001e6db85a01010101 0118010380301

Id like to write a program to read 2 main frequencies, first one from velocity sensor and second from ignition coil. Both of them to build a car gauge dashboard, (there'll be a few more analog signals to read tough).Given that i come from atmega 328 that has only one input capture module, id like to know if the stm bluepill has the capacity to read both frequencies in the same chip... I'll need to read 2 frequencies, read analog signals, writing steps bits to update gauges and display data in tft 2.4'' module, so im lookinf for advice about selecting the right chipRegardsJulian

Decawave dont deliver any of the example for this board

Using SPC582B chip with only 64 pins, the nexus interface pins will not be available.Does this mean that there are no trace possibilities ?

Hello,I struggling with MCSDK 5.Y.3 to control a 24V, 15 poles pairs, 300 rpm hooverboard-style BLDC motor, nearly no load, with a Nucleo F401 and a IHM08M1 power board.I try to use FOC control with 526 PPR quadrature encoder as main sensor as I want to drive this motor at low RPM (< 10 RPM). I flash the generated code on the Nucleo and then use Motor Pilot to test.Once the encoder alignment phase ends in Motor Pilot, I'm unable to control the motor: it does not even moves, whatever the direction and the speed I set through the GUI. I can hear some commutation noise, and the transistor on the IHM08 are slightly heating (~30°C after few min). I get no error in the GUI.However, if I give some momentum manually to my motor, it starts to turns and stabilizes at the speed set in the GUI, but then changing the speed in the GUI does not change the speed of the motor. This behaviour happens in only one (the negative) direction: if I give momentum in the opposite direction, the motor simply

I am using an STM32F407 MCU as an I2C master, my code built on the LL API of the STM32F4Cube IDE (version 1.25.0). I find that quite often, i.e. always within a handful of bytes, the BTF flag fails to set when I am doing a multi-byte TX. Single-byte TXs always work, it is only multi-byte TXs that suffer from this problem. I do not appear to receive a NACK from the far end (i.e. I2C_FLAG_AF is not set while I'm waiting for BTF to set), just not a "set-BTF".What reasons might there be for this?My code follows the pattern of stm32f4xx_hal_i2c.c as closely as possible and can be found here, where this is the send() function that gets stuck. Below is a sample log of a problem case (you can match the log points with the code), a millisecond timestamp on the left: you can see that the BTF flag is normally set almost immediately (within the millisecond resolution of my timestamp) until suddenly it is not, even after waiting for 10 milliseconds.24876: EVENT_i2c1: TXing this many bytes 8 24876:

According to the datasheets for the L9963E and L9963, they state they are both "a Li-ion battery monitoring and protecting chip." There is no explicit mention that they won't work with LiFePO4 batteries and it's unclear if ST includes LiFePO4 batteries under "Li-ion" batteries. Want to confirm if LiFePO4 can be used with these chips.

Hello,We are in process of selecting a suitable BLE SoC for an industrial sensor network design which would support coded PHY LR communication. The BLUENRG-355Ax MCU fits all the requirements perfectly except for one major point - Embedded Bootloader Errata.The Errata sheet says that the Embedded Bootloader would fail to boot up the chip properly if we enable readout protection and/or disable SWD. This is disastrous since our BLE applications require the peripherals to securely connect to the central device and for security the internal flash is preferred to store keys. Could anyone from ST recommend a workaround for this? Has this been addressed in recent versions of the chip? And if so is there a way to ensure that we order the latest chips which probably won't have this issue?Thanks & Regards,Mayuresh Manjrekar

Dear ST Community,Ten days ago I already asked this support request but no one single response came from ST.I just bought and received an ST-EVALMKI109V3 + ST-EVAL212V1 after attending the webinar "Develop effective AI solutions for monitoring vehicles using a single sensor".I get this error that says it does not know the chip id when I select the MKI212V1 as shown in the screenshot above.All my software tools seem to be on the latest revisions. Anyway I updated the board with the last firmware using this video : Same issue.I also joined the picture of both boards.the error I get from Unico (above)a zip file that contains a few snapshots attesting the configuration presented during the webinar and which is identicalCould anyone help me please on this? Buying more than 100€ for 2 non-functional boards is already frustrating. Receiving no help is even more frustrating. Do you believe it lives up to the image of ST-Microelectronics ? Best regardsThierry

Hello guys,I have just started working with stm32 controllers. I am trying to capture the frequency of signal using timer 2 input capture mode.I am getting absolutely correct frequency if i use ARR = 65535 but when i use ARR = 0xffffffff (As timer 2 is 32bit) i am getting wrong result.I am using this reference equationFrequency = TIM_CLOCK / ((C2-C1)*(prescaler+1))Where C2 = capture value 2 // Both Rising edge C1 = capture value 1 TIM_CLOCK = 1Mhz TIMER_PSC = 16-1 SYSTEM_CLOCK = 16MhzPlease help if i am missing something.

Hi i build an application with fatfs implementation to log data.but when the file size reach 64kB, the SD card stop responding and i can not write on it.I used standard configuration for ff_confany suggestion to resolve the problem ?thank you.

I have decided to try out the X-Cube-SbSfu, i have downloaded the SW from the ST website,according to the documents available this is an expansion pack that can be added to the CubeMX.is this correct?where can I find information about the process that helps me accomplish this?

Hi, Expert,I have STM32F407-Discovery and I'd like to use CMSIS DSP Library for audio processing.When I checked the library version which is released, it looks 5.5.4.So, I downloaded latest CMSIS DSP Library and build it for cortex-m4 atchitecture,Before I integrate it on my stm32 project, I'd like to check that it is possible or not.Please let me know.Thanks,SeungKyu Joo

Hi all ~I have a question regarding dual display.I want to display same content at the same time to both display devices (LTDC and HDMI).But, As my understanding, STM32MP1 has only one display controller. https://community.st.com/s/question/0D53W00000DH4AqSAL/can-i-use-dual-display-on-stm32mp157c-chipsetMy TFT-LCD's resolution is 1280x800 (10.1inch) and support LVDS.So, if I can implement dual display, LCD and HDMI will has same resolution. Isn't there any solution to implement dual display implementation?Actually, I tried the following.  As a result, both display devices can be display same content at the same time. But there is one problem that display quaility is not clearly.And both display devices has exactly same quality. To be honest I don't know exactly that this application is right.Can I get some advice?Thanks regards
