Hi,I am a newbie on microcontroller but, I can read / write on the GPIO port and control a servo motor in PWM with a timer.Now, I am starting to play around with ST BLE for control the GPIO port and servo motor.I use: Nucleo-F401RE X-NUCLEO-IDB05A1 board.To check my hardware and configation, I tested the demo programs and everything works fine.Now, I would like to create my application using the X-NUCLEO-IDB05A1 board.To configure the Nucleo-F401RE, I use Stm32CubeMx 5.6.1.I installed :STM32F4 1.25.0 PackageX-Cube-BLE1 5.0.0 stack and sample applications for BlueNRG-MS module.I created a new project and followed the configuration procedure indicated in the document:"Getting started with the STMicroelectronics X-CUBE-BLE1 software package for STM32CubeMX"I fine this document here: C: \ STM32Cubeprojects \ Packs \ STMicroelectronics \ X-CUBE-BLE1 \ 5.0.0 \ DocumentationAt the end of the configuration procedure, in the "Project Manager -> Advanced setting" tab I should get this:Bu

I am working with the STM32MP1-DK2 development board and am trying to use RAUC to do image updates. I am using an SD card with two bootfs and rootfs partitions with one pair being active at a time. Currently I'm in the uboot integration stage where I need to create a script to change the active bootfs and rootfs, below is an example that rauc provides. I've looked at the uboot environment variables but can't seem to find which ones set boot and rootfs partition to use?I see reference to a scan that is done to detect a bootfs but not sure how to modify it. For this application the partitions are going to not change so maybe it's better to remove the scan all together and hardcode the values.uboot env:altbootcmd=run bootcmd android_mmc_boot=mmc dev ${devnum};run android_mmc_splash;run android_mmc_fdt;run android_mmc_kernel;bootm ${kernel_addr_r} - ${fdt_addr_r}; android_mmc_fdt=if part start mmc ${devnum} dt_${suffix} dt_start &&part size mmc ${devnum} dt_${suffix} dt_size;then m

Hello everybody,I need a power conversion DC-DC 24V to 3.3V. So I went to eDesign suite who recommendend me the following architecture:I reproduced it in my design: I produced the board, and when I apply 24V on the input, I obtain only 0.9/1V on the output.Someone have an idea why?Taking in account that I had to use a different inductor from the one recommended (same inductance, lower Isat). And there is another DC/DC converter after this one, supposed to convert 3.3V to 3.0V.Thank you.

Hi,I am not able to connect NUCLEO-L4P5ZG board to a PC and ST_LINK utility. It alway gives me "unexpected error".

I have a problem with launching both cores in STM32H745 in CubeIDE.I've set that configuration:connect under reset for CM7, with halt all coresCross Trigger Interface (CTI) , allow other cores to halt this core and signal halts events to other cores for both core 4 and 7different port numbers for first and second corein CM7 startup I added file *.elf from CM4 with option to download CM4 corein CM4 startup I don't allow it to download this coreI set launch group which starts both coresAfter starting I see that the LED on CM4 turn on only for a very short moment and then turn on only LED on CM7. Therefore, I can debug only with BOOT0 connected to 3V3. If it's not connected it's impossible to connect with ST-Link. I guess that it's not right but I really don't know what cause this problem. Maybe it also cause that core CM4 finishes working. Can you help me or give any link which could help me to configure debugger in CubeIDE or tell why I have a problem with connection without BOOT0?

The STM32F103 does not have a Synchronous Prescaler. and the Asynchronous Prescaler can be set to (2^20 - 1) in the MCU.But STM32CubeMX doesn't allow a number higher than 127. Not really a problem of course, just a bit confusing. 

I had gone through the datasheet and user manual. I could not fined respective CAN_TX, CAN_RX pins on the board(Pin Number PA12(CAN_TX), PA11(CAN_RX)). These pins are not available on the Discovery board. Then how can I take CAN TX, RX data to the external transceiver? Can anybody help me to find those pins and how it has to be proceeded for building the CAN ?

Hi STCommunity,I have a project started in keil, configured through CubeMX via keil's "Manage Run-Time Environment" with RTOS2 RTX5 implemented, just as this guide shows: https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.keil.com%2Fpack%2Fdoc%2FSTM32Cube%2Fhtml%2Fcubemx_using.html&data=04%7C01%7C%7Cde618df5b527410658bd08d89298fd9c%7Ce369e0ccf38d406b876915438de2e3af%7C1%7C1%7C637420533809252717%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=cEhUmu%2Fy2t81Cfnj0qNkipiDSKpnWlhIIZviJTjtzlI%3D&reserved=0.From here I'd like to use TouchGFX designer to generate some GUI-software for a NON-touch LCD display for me to implement in my project, but even though ST’s guide claims that it's doable in several of your tutorials/guide (one of them: https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsupport.touchgfx.com%2Fdocs%2Fdevelopment%2Fdevelopment-introduction%23custom-hard

Hi, NUCLEO-F303REX-NUCLEO-IHM07M1Maxon motor 496653 with 5.8:1 gear ratioMotor Profiler 5.4.4MotorControl Workbench 5.4.4STM32CubeMX 5.5STM32CubeIDE 1.4.0I have created a motor profile using the motor profiler and confirmed the hardware is working correctly. I have then attempted to create a position control project using the AN5464 as a guide. I have got to a stage where the motor doesn't rotate at all. I have tried to debug the code and I have realised that it gets stuck at the "while(MC_GetAlignmentStatusMotor1()!=TC_ALIGNMENT_COMPLETED){}" line of code. I have attached a PDF showing the value returned by the function. I have then tried to connect to the board via the monitor in the motor control workbench and it shows FOC duration and Software error as soon as the MC_StartMotor1() function is called. Does anyone know what's going on? Thanks in advanceKind RegardsManpreet Singh

Hello,I am currently trying to run a Machine Learning application on the SPC584B-DIS MCU. I used SPC5Studio with the AI plugin to create the project and it compiled without an error. The board is connected to the PC by USB cable. When I try to validate the project on the board however, I always receive the error: "LOAD ERROR: STM32 - no connected board(s), invalid firmware or the board should be re-started."From the manual (https://www.st.com/resource/en/user_manual/dm00532742-spc584bdis--discovery-board-stmicroelectronics.pdf) I understand that I need to set the jumpers in a certain way to enable the communication between the board and a host. I am fairly new to embedded programming however, so I don't understand how to set these jumpers properly so I can communicate with the board. Can someone help me understand?Best regards

I am using VL53L1X for indoor presence detection, mounted on the ceiling and looking at the floor, and it is doing great. However recently I tried it in a new location, and I have nothing but errors. I have several sensors there, and all of them are stuck with error type 2, and a sig rate at 0 for 90% of their measurements (using different ROI and different time budget. Usually I use 16x16 and 100ms and it is doing great, but here it seems nothing goes). It is not in direct sunlight, but one wall is open to the exterior, so the ambient light is partly sun, partly artificial light from neon light bulb. However the ambient rate doesn't seem to pike higher than I use to see in other cases. The floor is a bit dirty, its paint is dark but reflects light a lot. However errors are the same when an object is present, so the floor may not be the cause.Is it possible that an unknown source of 940nm could mess this up ? An IR CCTV for instance ?

Hi,i am looking to buy a couple of those for a project i just startet with.Is there any differents that is worth to mention between those 3 types?Just looking forward to which one i should buy. Regards

Hi,I'm looking to create an zigbee endpoint device. I've selected the STM32WB30 for my project and have been configuring in CubeMX. This all goes well.Now I need to flash an wireless stack to the M0, but there is no zigbee stack for the STM32WB30.Does CubeMX put the stack in the user app for the STM32WB30 and work with the MAC 802.15.4 fw? Or is what I'm trying not possible?

Hi,I am currently going through the "STM32 security in practice workshop" which is for the G0 and I really like it.Now my target is a G4 with dual bank. So I wonder if you have some code for this MCU as it probably needs some more settings to add because of its 2 banks. Or does the HAL refer to bank 1 (where the bootloader is) anyway by default? I do NOT need 2 images, just to handle the dual-bank design properly when adding the protections.You don't set the secure memory area in code in the workshop. Is there any special reason for this and can this be done from code?And what is actually the difference between the code presented in the workshop and the X-CUBE-SBSFU. Which is recommended to use? I find the practice workshop easier to understand and implement than the SBSFU. Additionally, SBSFU projects do not seem to be based on CubeMX (.ioc) and therefore don't offer easy implementation of modern bootloaders using FD-CAN or similar as far as I understand.Thanks,Anguel

Hello,How can I watch the values of global or static variables for ADC Module. When I add the variables which keeps data to the watch table, I dont see what's going on. They don't change. ( Also I wanna learn this for Timer and other Modules)

we are configured that pin as Input. We got 0.5V drop at PA7 pin after flashing code.Please let me know the resistor values for all GPIO pins

Hi :) I am using SAI in TDM-8 mode, my MCU is a STM32F446RE. I want to use a PCM1681 but so far I am simply analysing the outputs. Everything seems to work fine apart from the MCLK output pin which gives me nada.I followed what is explained in the RM0390 (https://www.st.com/resource/en/reference_manual/dm00135183-stm32f446xx-advanced-armbased-32bit-mcus-stmicroelectronics.pdf) section 28.3.8 "SAI clock generator" (pages 941 & 942). In particular:with:sai_x_ker_ck = SAI clock set in Clock Configuration in CubeMXMCLK_x = sai_x_ker_ck / (clockDivider * 2) or = sai_x_ker_ck if clockDivider=0SCK = MCLK * frame_length / 256In my case I need 8 slots of 32 bits each per audio sample, so my frames are 256 bits long, so I have SCK=MCLK=256fs. And because I want the best accuracy possible for fs=44.1kHz, the best I could get was 0.22% with a sai_x_ker_ck of 11.289474MHz which is almost 256fs.So in my case I have sai_x_ker_ck = MCLK = SCK, and I found that in this case the MCLK pin is not outp

Hi, I am using STM32CUBEIDE, project creation is simple. i modified that code and i add the more function. After i need to add another peripherals, so i use .ioc (stm32cubemx) add another peripherials , after save it ask create, when into my project modified code doesnot exist, new fresh code will appear. Can anyone tell me how to overcome this one.??

I just started using the SensorTile Dev Kit for one of our projects. As part of testing, I was trying to update the firmware using the ST BLE Sensor app but ran into problems. The firmware file was uploaded successfully but the board stopped responding. After waiting for a while, I tried the reset button but still no luck. I'm using the SensorTile mounted on the cradle expansion board in the kit. Is there a way to recover or reset this SensorTile? We have a ST-LINK/V2 available here but not any connectors that works with the cradle. Is it possible to use the ST-LINK or another way to recover this SensorTile? Any suggestion that you can give is greatly appreciated. Thank you!

Hi,First of all, I apologize for my English level, I am not a native speaker. I hope you can understand me :) Explanation:1) PHYSICAL WORL: I have searched for information on the electronics behind the memories. In 32 bits microcontrollers, the memory digital circuits have 1 memory address per 4 bytes. In other words, if you would want to store a "char" in the byte 0, you will use the same "real or physical" memory address than if you would want to store other "char" in the byte 1. ( 4 bytes share the same physical memory address )2) SOFTWARE WORLD: When you store two "char" variables in memory and print their memory address using C language, you can see that they have different memory address. For example:char a = 'a'; // use memory address 0x00000000char b = 'b'; // use memory address 0x00000001My question is:¿What is going on?¿Are the memory addresses of the software different from the real ones?¿Are they "fictitious"?Thank you!
