Hi Team, I'm currently trying to enter low power mode mode stop 0,1,2,3 and standby mode with Trustzone enabled using Threadx. The device is entering low power mode when interrupt triggers the thread is not resuming it still in the low power mode. Is there any material to proceed low power mode in trustzone enabled in Threadx.

In your application note AN5020 and related to JPEG reception. i have some questions and hopefully you can answer them so every thing work. Each JPEG stream is divided into packets, which have programmable sizeWhat does JPEG Stream means? is it JPEG frame or what exactly?What packets mean? Minimum Code Unit (MCU) or what?also how many packet can be received between every HSYNC, one packet or more?how this packets can have programmable size and which register responsible for this?

Hello, I have a Nucleo H745ZI-Q  board  in this am working Ethernet fallowed some examples when doing ping test response is Destination host unreachable(am using CM7 and  done memory configuration also).

Hello everyone, I use stm32f4 discovery. I want to communication of mpu6050 sensor with I2C. When I push to run button Led 7 is burning. Why is that. ?  Give me comment .Thankss

Hi,I'm using STM32H743ZI with STM32CubeMX 6.9.1.I used to work with an really old STM32CubeMX , and I decided to move to the latest version of both IDE and MXso I had to configure the IOC file from scratch manually - since migrate wasn't possible (too old)I copied the same configuration like the old IOC file , and the same for the clock configuration - but in the clock configuration I saw an issue - I can set the SPI123 to <=200 MHz while the max size is 480 MHzso I searched online and saw few solutions that didn't work such as:https://community.st.com/t5/stm32cubemx-mcu/stmh743zi2-cubemx-clock-setup-max-frequency-not-allowed/m-p/148775https://community.st.com/t5/stm32cubemx-mcu/cubemx-stm32h753iikx-clock-configuration/m-p/98576#M2796this is my clock configuration:also my RCC configuration:pls I need your help :)thanks

I'm using the nucleo-f302r8 and I want to turn on then turn of the user led (the ones on the stm32 board) thanks to a push-button on my personal breadboard. How to achieve this? Hardware : a nucleo-f302r8, a breadboard, a push-button arduino, 2 male-female wiresSofware : STM32CubeIDE

Is it possible for STM32H5 to monitor the CAN bus when MCU is in sleep mode? Upon CAN bus activity detection, MCU automatically performing the wakeup sequence to be back in normal run mode.

My setup is as follows: I have a NUCLEO-H563ZI with an STM32H563ZIT6 and I am communicating through I2C with the 6D IMU, ISM330DCL. Moreover the ISM330DCL is on the STEVAL-MKI182V2.My I2C-bus is very confusing. First I get everything set up exactly as this guy does in the following vid: https://www.youtube.com/watch?v=isOekyygpR8&list=PLEBQazB0HUyRYuzfi4clXsKUSgorErmBv&index=14.Well I didn't use the same setup but of course I used the respective registers which have to be used in my case, instead of those in the video. Then I get everything running and I get a bunch of "0.0g" readings. So I decide to unplug a pull-up resistor to see if it's even working and to my surprise it did the "Error, TX" message came up and I was satisfied that it picked that up. I put the resistor back in and the "Error, TX" message doesn't go away. I rewire everything a thousand times it still didn't work. Until finally, I changed My WHO_AM_I address to "0xD5U" instead of "0xD5" and it worked

I'm working on SPI communication between two Nucleo-H743ZI boards. I'm using ST's HAL, and the SPI polling API HAL_SPI_TransmitReceive.It's working fine until a bandwith of 12Mbits/s (SPI kernel clock at 200Mhz and prescaler 16, the CPU is always at 400Mhz) but fails above (smaller prescaler).I want to understand since 24 or 48 Mbits/s doesn't seem much even in polling with a poor quality software.With prescaler set to 8, I don't have SPI error like overrun or other (I checked directly in registers), however the data are not correct. looking closer to the data, I've noticed that there is only a shift of one bit.More precisely I should receive (in hexa :( 0x30 0x31 0x32 ... And I receive 0x18 0x18 0x99...In binary:expected 0011 0000 0011 0001 0011 0010...received 0001 1000 0001 1000 1001 1001...If I shift the received bitstream to the left I get exactly the right result.Does it ring something to you ? Could it be due to a bad configuration ?Obviously master and slave have the same confi

Hey all,I'm trying to locate the datasheet of the following device:I think that it is a Zener, but I am not 100% sure.I've done the usual "Google" for the text, but I can't seem to find it.Thanks.

I have an application that requires a large number of digital outputs, but they can be very slow.The "true" SPI ports in my design are already in use for higher-performance peripherals, so my plan is to use a USART in synchronous mode to generate the data and clock outputs from the MCU to the shift register chain. So in my case, this would require the use of USART_TX and USART_CK. Because these are just output shift registers, no data "comes back," so the receiver on this USART isn't needed for anything.Reading the STM32L051 datasheet and register reference, it seems like the CK and TX functionality can be assigned to suitable pins as alternate functions without having to also assign RX (which I don't need) to a pin. And then beyond that, I could also disable the receiver functionality of the USART itself. This would let me use this USART to latch out data and clock without having to waste an IO pin on the unneeded USART_RX. Can anyone confirm that I'm understanding this correctly

Almost all sample projects have support of STMCubeIDE in the development board B-U585I-IOT02A except following bootloader projects.SBSFU_AppliSBSFU_BootSBSFU_LoaderOn release note it is mentioned that, will be added support in the next release but date is not mentioned. May I know the date by which we will get the STMCubeIDE support?

Hi everyone,I observed a strange behaviour while creating software for a STM32F091. I am using CubeIDE and HAL. FreeRTOS is used as well. The application is running as expected so far, but when I try to run it in debug mode it does not work. It crashes at different locations within the HAL_Init() function. Did someone experienced a similar behavior and probably has a solution?Best regards

Hi , I am using STM32L031x4 MCU for my project. In the document it shows 2 UART ports, can I use these 2 UARTS simultaneously ?I need 2 different UARTS for sensors. 

Dear CommunityI recently acquired a STWIN.box development kit and proceeded step by step according to the document "Quick Start Guide High-Speed Sensor Datalogger application for STEVAL-STWINKT1 (HSDatalog)" but I can't get the CLI examples to work (slide 27).When I start the CLI batch file "USB_DataLog_Run.bat" the output is:STWIN Command Line Interface exampleVersion: 2.0.0Based on : High Speed Datalog DLL v2HSD_DLLv2: DeviceManager createdNo devices, exitingPress any key to exitI've noticed that when I connect the STWIN.box via USB, the computer doesn't seem to recognize any devices, resp. there is no notification by a system sound nor any change in device manager windows.I'm also not sure which FW should be loaded on the STWIN.box, the Android app shows a long list, and I haven't found any information about the different FWs.Could you please give me a hint how to proceed?Thanks in advance

Hi everyone,I'm a french student in internship in a company and my project is about using 3 products : the NUCLEO-F302R8, the X-NUCLEO-IHM08M1 and a BLDC motor from Trinamic. Please consider me as a total beginner in this and so please use simple words.I watched few videos how to turn on or turn off a motor with this kind of devices and I found out using ST Motor Control Workbench is what I need and the following tutorial could be really useful : https://wiki.stmicroelectronics.cn/stm32mcu/wiki/STM32StepByStep:Getting_started_with_Motor_ControlI launch the ST Motor Profiler then enter the pole pairs (4), the max speed (4000rpm), the max current (5A, the real max current my motor can handle is 6.67A but my generator can't supply above 5A) and the voltage bus (36V). However when i try to click on Start Profile button after connecting the board after few second the board start smoking (the motor do spin a little) and then the profile stop because of overheat fault. What's the issue?Thanks

making new project for H563 cpu has problems:1. output as makefile is greyed out - why ?2. output for stm32cubeIDE is possible, but output shows problem:what can i do now ?

Hi there!I'm working with a nucleo144-STM32F767zi and facing a problem with irregular ADC conversions (HAL_ADC_Start_IT) which are triggered by a eg. 50 kHz timer update event (every 20 us TIM1 fires an update event)ADC Clock prescaler seems to be PCLK2 / 4 = 96 MHz / 4 = 24 MHz according to my clock configurationSo I expect the quickest ADC conversion rate to be 24 MHz / (12+3 cycles) = 1.6 MHz -> 0,625 us which is way below my desired timer triggered conversion of 20 us.However my adc readings are irregular every 1 millisecond for one reading. In the image below I have triggered a output pin which I read via an oscilloscope. void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef *hadc) { adc_val = HAL_ADC_GetValue(&hadc1); GPIOA -> ODR ^= GPIO_PIN_3; }  I don't do anything with the adc value yet. When I look at the signal, I have every 1 ms this longer timing of up 7-10 us longer for one reading (the conversion takes 7-10us more time). This limit my maximum freque

The MCU is great, but the datasheet (in particular the SPI section) is very hard to read. Whatever the original language was, it wasn't English, and I guess Google translate has been involved. I've added an example below, and hope for ST to update the datasheet in the near future.Example 1:To understand better the next detailed content of this section, the user should capture theconfiguration impact and meaning of the following items at first:Data size (DSIZE) - defines data frame (sets the number of bits at single data frame).FIFO threshold (FTHLV) - defines data packet, sets the number of data frames at singledata packet and so the occurrence of the packet occupancy events to handle SPI dataregisters either by software or by DMA.Data access – a way how to handle the SPI data register content when the transfer databetween the application and the SPI FIFOs upon a packet event. It depends on the packetsize configuration. Optionally, multiply data can be handled effectively by a single a

Hi, I am figuring out how 6-step algorithm works. I generated a project using 6-step algorithm with B-G431B-ESC1.In the ADC settings, ADC1 consisted of 2 regular channel (Vbus, Temp) and 1 Injected channel (Bemf_W)So I thought ADC2 should be consisted of 2 injected channel (BEMF_U and BEMF_V).However, there was only 1 Injected Channel enabled (Channel 17 -> BEMF_U)here's screenshot for stm32cubemxCan someone tell me is it not necessary to sample Bemf_V? or is there an additional code to sample this?Thanks   

Hello,I have a jewelry brand and i´ve been thinking about making smart jewelry with NFC technology. I found a 5x5mm NFC chip but it´s still too big for fine jewelry; i read somewhere in a forum that i can find here the smallest NFC chip (2x3mm), does that chip exist (I think is in the ST25T series)? or which one do you recommend for that purpose?.Thank you in advance.

When generating u-boot an error occurs: stm32mp15-scmi-u-boot.dtsi:135.1-6 Label or path scmi not found. Following the steps in the OpenSTLinux 5.0 workshop document to update the device tree files.  It mentions to include an scmi.dtsi file for u-boot for the specific board. Is there any more information how to do this? This is a custom board with an STM32MP157AAA3 using legacy power. (regulators not PMIC) and this board worked fine with a previous ECO system but in ECO 5.0.0 SCMI was introduced.
