I have a STM32F7xx MCU connected to a Winbond W25Q01. The datasheet says the chip will run up to 133MHz. If I set the MCU clock to 108MHz and the quadspi clock prescaler to 0 so that they are running at the same frequency, the chip initializes and communicates no problem.However, if I set the MCU to 216 MHz and the quadspi clock prescaler to 1 so that it is running at 108MHz it won't initialize and I can't communicate with it.If I set the MCU to 216MHz and the prescaler to 2 so the quadspi clock is running at 72MHz it initializes no problem.Summary TableMCU Freq [MHz] | Prescaler | Quadspi Freq [MHz] | Result108 | 0 | 108 | pass216 | 1 | 108 | FAIL197 | 1 | 98.5 | FAIL155.5 | 1 | 77.75 | pass108 | 1 | 54 | pass216 | 2 | 72 | passI believe that the failure mode is that when I query the status register I get a corrupted response and the code hangs thinking that the chip is busy when in reality it is not. But I can't explain why when the MCU and qspi are running at the same speed (108MHz)

Hi guys,I'm working in a project with a STM32L412RBT6. Due to a misunderstanding, the company i'm working with, bought a big stock of STM32L412RBT6P. I just discovered the meaning of that final "P" in the code and i'm trying to figure out how big the problem is.I looked at the application notes and I noticed that there are two pins in which I have to connect an external 1.2V reference (in my project they are not connected GPIOs). I could not understand if it is mandatory to connect this external reference in case I do not use any low power mode (we do not need them in this project).Anybody have suggestions to help me ?Thank you,Riccardo

I tried to connect the STLink to the STM32G030K6T6 by connecting SWCLK SWDIO VDD and GND pins, but the STM32CubeProgrammer can't detect the MCU.I also tried to check with the logic analizer the pins and there is only a little signal from the stlink but no response from the MCU.I think the problem could be that the SWCLK and BOOT0 are in the same pin and this is pulled down internally. So how can I connect and program the STM32?Thank you so much

HelloSTM32CubeWB has two demo applicationsBLE_Peripheral_LiteCDC_Standalone (USB)It seems impossible to run the BLE with USB. I added the CDC part to the BLE app and they don't work together (if you disable one, the other works fine).What is the conflict here? The USB demo is not useful if it breaks the wireless part of a wireless MCU.Thanks

Hey!Which function should I use to check if the TouchGFX engine is in "drawing next frame to RAM" state and which one to check if "next frame is ready in RAM"?I got following setup on mikromedia Plus board: STM32F407 -> SSD1963 -> TFT 480x272. TFT connected to SSD1963 with RGB interface and MCU connected to SSD1963 with custom parallel 8080 interface (implemented as simple bit-bang). I was able to set up TouchGFX with "partial frame buffer strategy", everything's working. But the narrow part is the MCU interface, so the slow filling of the display is visible with naked eye when I change image on the whole display.Now, my goal is to implement double buffering, but on SSD1963 side.It has 1215Kb avaliable for frame buffer. My TFT requires 480x272x2 byte = 255 Kb, so it is possible to arrange two framebuffers within SSD1963.So what I'm gonna do is to modify existing project to be able to "swap" those buffers when frames are ready to transfer to display to avoid tearing and slow

Dear Sir/Madam, I am currently working on the LSM6DSM IMU for a visual-inertial SLAM use and I have some questions about its features. Here is my IMU settings : Gyro : ODR = 208Hz FS = 2000dps High Pass 260mHz Acc : ODR = 208HzFS = 2g Analog BW 400Hz Low noise Low Pass ODR/100- Do you have the Noise Density and Random Walk values for the gyroscope and the accelerometer and also their different bias ? - Do you know if these data are unique for each IMU or all the LSDM6DSM have all the same reference values ? - Should we pre-process our raw IMU data before using them ? Thank you in advance.

STM32F746-DiscoCapacitive Touch Panel FT5336STM32CubeIDE, Windows 10CMSIS-onlyI'm developing my first I2C driver for STM32F746 using CMSIS-only, and I've decided it would be great to test my I2C skills on built-in capacitive touch panel FT5336. I used ST-provided ft5336.c/.h to get register addresses (since FT5336 datasheet actually doesn't have them). So obviously my first thing to try is to read Chip ID register.Initially, I've developed DMA driver for it (yeah I can do DMA but still haven't tried I2C), but as I was running into an issue, I made a step back and went full blocking way. Interestingly enough, the results were identical.What I do:I write slave address in write mode (ACK), followed by ID register (NACK).Then I give it a little pause (~30us, well above datasheet ~10us for start setup; tried different).Then I write slave address in read mode (ACK), and receive 0x00 (NACK).I've carefully examined my signal with oscilloscope and logic analyzer, made sure timings are correct a

Hi everyone, @Kevin HUBER​ ​I am using stm32mp157f-dk2 with ecosystem 3.1, with weston support.I connected the HDMI display to the development kit, reset the device, but nothing displayed.​After checking, modetest show that the HDMI are properly connected, and the test commandmodetest -M stm -s 33:320x1480-60.08 -vrun successfully. But still, nothing displayed.​Anyone knows how to fix this?Actually, I have report this issue before, inhttps://community.st.com/s/question/0D53W00001L0jviSAB/failed-to-start-loadsave-screen-backlightBut I didn't solve that last time.​In addition, does anyone know to how remove the GTK demo from yocto/disable it from application?I tried to remove packagegroup-st-demo from CORE_IMAGE_EXTRA_INSTALL variable in image.bb, but it doesn't work.For now I can only disable it by stopping the entire weston service, which is definitely not what I want.​Regards, Leung

I am getting acceleration and gyro data using LSM6DSO32 chip. But I want to filter this data with internal filters, but I cannot activate the high pass filter of the accelerometer. In the code below, I want to send F4 (11110100) data to the CTRL8_XL control register, ie 0x17 register address specified in the datasheet, to set the cutoff frequency as ODR/800, but corruption occurs in the accelerometer data. How can I solve this?

Greetings,I am trying to read the color value of a pixel in hex form. The motivation behind this is the function available in simulator shortcuts as it states,F1Enables/disables the display of pointer coordinates as well as RGB color of the pixel at that coordinate (in hexadecimal).Link: https://support.touchgfx.com/4.19/docs/development/ui-development/working-with-touchgfx/simulatorI have tried many ways but got stuck at retrieving the value tft_framebuffer24 present in HALSDL2.cpp. Can anybody guide me on how can we retrieve the pixel color values at specific coordinates of my screen?

Hello,I want to control a timer period with a variable. The variable value is correct because I monitored it in the watch window. But the variable was not working in the timer settings.

Hi, my name is Vincenzo,I'm studying the MotionFX library and I want to understand In what order the quaternion is given by the MotionFX library. Reading the manual, I know that the MotionFX can compute:rotation, quaternions, gravity and linear acceleration data.Regarding the quaternion, I don't understand how the elements are ordered. It is an array with 4 elements: qw,qx,qy,qz (q0,q1,q2,q3). I suppose that it is the order, but can someone confirm it? Thank you in advance!

Not sure if this is the best forum for this question but I am using the USB OTG port in device mode as ethernet gadget. It works fine if plugged in from boot, or first plug in anytime after. But if unplugged and plugged in again it will not come back without a board reboot:[ 46.766872] dwc2 49000000.usb-otg: new device is high-speed [ 46.771014] dwc2 49000000.usb-otg: dwc2_hsotg_enqueue_setup: failed queue (-11)Error -11 is something like "resource temporarily unavailable". Ever seen this before?

I have been using HAL_SPI_DMAStop to abort my SPI transactions and usually it works, but every once in a while I notice my SPI bus gets all jammed up or whatever and stops working. I noticed that the HAL_SPI_DMAStop function is not returning HAL_OK.Should I be using a different approach when using DMA? Also, How would I do this same thing if using IT (interrupts) instead of DMA? I tried using HAL_SPI_Abort_IT without any luck.To add a bit more context, I need to be able to use the SPI receive command to always be listening to another device and this device is a slave to it. As data becomes available to transmit back to the master, I need to abort the receive transaction and start a TransmitReceive transaction. Also note that this is being performed within a callback function (ISR) because my timing requirements are extremely tight.Thanks!

HelloI'm starting to implement AES-GCM on STM32H753 (rev V).I've found an inconsistency between the HAL and the Ref Manual.The STMicro HAL for AES for STM32H7x3 is setting some bits called NPBLB in CRYP_CR register if the product revision is above rev B.But these bits are not documented in the ref manual rev 7.Is it just an error of the HAL ?
