I am searching for a schematic of the STM32L476RG Board. Can anyone help me, where to find it?I searched herehttps://www.st.com/en/evaluation-tools/nucleo-l476rg.html#documentation

I have a stm32f3discovery board and I want to start playing with the LSM303DLHC MEMS sensor.I seem to have found the original example code on github.So I guess I need to add both the header and c file to my project. I'm not sure how to go about this. Also, what is this procedure called? Am I "adding a library"? Or is it called a driver?

Hi all,I followed the instructions described on the wiki, page ADC_device_tree_configuration.Changing the sampling_frequency, I can achieve a sampling rate of about 10k. Going higher crashes the system. Reducing the parameter 'min-sample-time-nsecs' in the device tree did not solve the issue.Is it not possible to go higher with the sampling rate when using the iio interface? Would I option higher sampling rates writing a C Program accessing the ADC via mmap()?Any hint is appreciated.Denise

Hello,I am using the STM32L071 with the latest STM32 studio software. I cannot find any sign of the VREFBUF configuration in the libraries (I need to enable the internal voltage reference for the COMP1 peripheral). I have found this article for H7 device:https://st.force.com/community/s/article/how-to-configure-vrefbuf-on-my-stm32But it seems that the VREFBUF entry in the graphical interface is missing (in the libraries code as well).I would appreciate all help and feedback.

I have the connection on the image from AN5031 for my custom board and I my clock configuration can be seen on the other picture. Is my clock configuration correct and how its device tree code should be?

Hello,I'm planning to use a STM32L476 to acquire approx 150 analog signals. For some reasons, I have to periodically check the justness of the ADCs.I read in the RM that it is possible to connect internally DAC to ADC but I can not figure out how to select on which ADC & ADC channel the DAC output is "routed" to.Can someone point me to info related to this ?thanks

I am trying to get an example "TIM_timeBase" to run with the STM32H750B Discovery Board. The readme file says the following:  1. Select required configuration in memory.h in Templates\ExtMem_Boot\Inc.But, I have many of these files, for Cube V1.9.0, 1.9.1 ... According Info of my Cube IDE, I have version V1.9.0... so why do I have also the folder 1.9.1 ?Then the readme file says also following:In order to load the ExtMem_Boot code :  - Open your preferred toolchain :   - Open the Project   - Rebuild all files   - Load project imageWhat is meant by Load project image?Thank you

I'm currently implementing USB communication on the STM32F072R8T6 microcontroller with "Custom HID" class. I'm having problems receiving data from the Host (PC) in the function below. The following happens: I can receive up to 2 data packets from the Host and then I can no longer receive and process them. In the communication on the other side, sending from "Device" to "Host" I'm not having problems, but only to receive them (Host to Device). I followed the recommendation of this link for such an implementation https://www.youtube.com/watch?v=3JGRt3BFYrM&t=257s

Hello,I'm new to RFID and I have troubles with the RATS command of the ISO-14443 standard. I am currently working with a CR95HF (reader) and a ST25TA02KB-D (tag). The uC driving the reader is an Arduino UNO, this part is working fine so far.My issue is that I can't manage to have an answer from the tag when sending the RATS command. The error I get is the 87 : "Frame wait time out" according to the reader datasheet.I found similar issues and the main culprit seems to be the Frame Waiting Time :Link 1Link 2Link 3But even with this parameter set to 10ms I can't get a valid answer to the RATS command.Here is a capture of the data exchange between the Arduino UNO and the CR95HF until the RATS command :Protocol selection (FDT = 10ms) :>>> 00 02 05 02 00 00 21 00<<< 00 00REQA :>>> 00 04 02 26 07<<< 80 05 42 00 28 00 00ANTICOLLISION (there is only one tag in the reader field) :>>> 00 04 03 93 20 08<<< 80 08 88 02 E3 00 69 28 00 00SELECT :&

I create the TouchGFX program. Then I browse the folder, open the project with double click. If I download the program to my board (F469I-DISCOVERY) it works. I can modify the Model, Presenter and View files as well. But if I want to configure an SPI channel in the CubeMX part then I save this and I download the code (there aren't any errors) the display stays black. First I tried to add a new task to the project and I tought that it's my fault because I don't really know the FreeRTOS. But it's not about the task. As I mentioned it doesn't work if I add a GPIO or SPI channel.I already spent months to solve this problem but unfortunately I can't.I would be grateful if somebody could help me!Thank you!

I'm starting using SPC5 familly and I discover chips and tools.I would like to first start with a low cost solution and then (second generation of product) to have my project ASIL-B certified. I understand that I will have to go with a STM 3rd party like EB tresos, isn't it ?I would like to know if there is a difference between low level drivers included in free SPC5 studio and those included in certified MCA ?And , for my understanding is MCAL interface just above low level driver ?Thanks in advance,Christophe

Hello,In the annex video it is mentioned that the project archive is available for the Nucleo board project with X-NUCLEO-IKA01A1, however when I download the materials archive it appears to be missing.Could you confirm this is the case, if so would it be possible to make this project available for download also?Many thanks,Anthony

Hi,The vl53l5cx_api.h file contains information about interesting functions to enable or disable the internal VCSEL charge pump:/** * @brief This function is used to disable the VCSEL charge pump * This optimizes the power consumption of the device * To be used only if AVDD = 3.3V * @param (VL53L5CX_Configuration) *p_dev : VL53L5CX configuration structure. */ uint8_t vl53l5cx_enable_internal_cp( VL53L5CX_Configuration *p_dev);     /** * @brief This function is used to disable the VCSEL charge pump * This optimizes the power consumption of the device * To be used only if AVDD = 3.3V * @param (VL53L5CX_Configuration) *p_dev : VL53L5CX configuration structure. */ uint8_t vl53l5cx_disable_internal_cp( VL53L5CX_Configuration *p_dev);Unfortunately, I cannot find other usefull information about this topic in the documentation.What is the default state of the internal charge pump after initialization (ULD ver. 1.3.4)?What is the expected power consumption delta when ch

My project uses LTDC as application tick source and two frame buffers. I am trying to understand:1. What the current frame rate (I understand this is same as vSync frequency) is. I know it can be measured by monitoring vSyncFreq GPIO. But I want to see where it is in code.2.What are the steps to change frame rate? I would like to see it in code please.If frame rate is change is achieved by changing the pixel clock, what is the relation between two.  I appreciate your help.

Okay, thread number 371982 about the STM's UART... - but maybe not?I recently found that I'm using some blocking printf / UART version, so I wanted to change that to non-blocking via DMA.So far so good, works flawlessly.Until I start "firing" the printfs, then it looks like parts of the previous strings are overwritten by the following printfs.I think that I wait for all the right flags before starting a new DMA TX (I know that if the DMA says it's finished that there might still by a byte in the peripheral) in _write(), and the single printf (or more with some pauses) shows me that it's generally working.So this works:printf("string1");... do other stuff...printf("string2");This doesn't:printf("string1");printf("string2");So after having checked UART and DMA again, could it be GCC's printf memory handling? So that rapid printfs use the same memory space, and older data is overwritten by newer printfs?Here's my _write() function:Note: if I put the DMA transmit before the while loop, ev

I'm trying to setup STM32F429I with TouchGFX, but during the debug this message appears:How can I enable it?

I want the STM32H75x, but it's hard to find in my country. That said, I don't want to write clones of "anonymous" companies.I wonder when production will be back to normal.

The reference manual states that the STM32L452 should be able to use an TIM3_TRGO as a trigger for ADC conversion:Though when I try to setup the "External Trigger Conversion Source" in STM32CubeMX there is no drop-down option for Timer 3, only TIM1/TIM2/TIM6/TIM15:Am I doing something wrong? Can I just ignore the STM32CubeMX and insert the appropriate EXTSEL-bits in the code myself?

TL;DR What's the magic sauce for connecting to an STM32F7 with SWD on ST-Link?Hello everyone. I am perplexed because I have been unable to program my custom board based on the STM32F765VGT6. (Hardware Eagle files + pdfs, Logic data captures, and some screenshots attached for reference)When I try to program my board with ST-Link I get the error "Error in initializing ST-Link device.Reason: (4) No device found on target."But I can't find a lot of information on what that means. My problem seems very similar to the unresolved thread here:https://community.st.com/s/question/0D50X00009XkXslSAF/stm32f103rbt6-error-no-device-found-on-targetAs suggested in that thread I have confirmed that:Reset is pulled highBoot0 is pulled lowVCC is stable at 3.3V and appears at all desired pins of the board (according to AN4661, https://www.st.com/content/ccc/resource/technical/document/application_note/b0/5c/ba/b2/cb/10/41/dd/DM00164549.pdf/files/DM00164549.pdf/jcr:content/translations/en.DM00164549.pdf)GN

Hello,I am trying to port SBSFU example project on STM32L433RC board. I followed getting started and integration guide to integrate STM32L432KC SBSFU 1 image example project(after modification) on STM32L433RC board. Below is the image where it gets stuck and waits for New user firmware. I ran scripts from MOOC workshop. It just uses UserApp.bin to download on board. Not sure why the code is trying to ask to download new user firmware. Can anyone help in pointing out if I am doing something wrong?Thanks!

Specifically, when T_VCC is not supplied, what state are the pins in for the STLINK-V3SET? We are using the SWDIO, SWCLK, and JTAG pins on the STDC14 connector CN1.

Hi Guys,first time poster here and kinda a noob in deployment of Models, so sorry if i forget to mention something.My Projekt:Currently i developed a ML model in python, which is working and takes as Input float numbers. Now i wanted to deploy it on an STM32H747I-DISCO Development-Board as training with the STM32Cube-AI component. The validation per "validation application" was fine, so i wanted to write an manuel code so i could do pre- and postprocess the data. Therefor i used a dummy dataset, where i know the results of the inferenz and wanted to do an inferenz with the following code. It gives me no error, but the results of the inferenz are wrong/ not defined. The result of the inferenz should be ~1, but it gaves me the following:The Definiton of the input is for one float four ai_i8, which together gives an float number 1 (which mantisse, exp and sign) and in the code it looks like that: It would be great if someone can explain me, how i should give my Input to the ai_network_run
