Hi all,How can I create swap partition in STM32MP1?Previously I did get an answer to how to increase the rootfs size. Any guidance on this will be highly appreciated.TIA

Hi all,Our team was brainstorming around a feature which we want to provide in our product.However to achieve the same we would like to understand if we can perform the video capture via camera and stream the same over the network to some node. Or do some kind of screen share and stream the screen capture over the network. Is it possible to achieve this capability on STM32MP1?

Hi, I wonder in which state are the GPIO lines of STM32F407VG BEFORE loading program to flash memory.Thanks :)

In this example its mentioned that it can rotate RGB565 image by 90 degree using MDMA. i cant find the code for 90 degree rotation so its not possible or what exactly??@Imen DAHMEN​

Hi all!I got something new for you. We have a pcb with an STM32f446re chip on it. For stability reason, we put an 20Mhz external clock on it, but the problem is, we are still running on 16Mhz (measured it with a toggled gpio on the oscilloscope.) The pulse should be 500ms long but results in 625ms.Now, here is the system clock init function which is calles FIRST in the main:void system_clock_config(){    RCC_OscInitTypeDef rcc_osc_init {};    RCC_ClkInitTypeDef rcc_clk_init {};    __HAL_RCC_PWR_CLK_ENABLE();    __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE3);    rcc_osc_init.OscillatorType = RCC_OSCILLATORTYPE_HSE;    rcc_osc_init.HSIState = RCC_HSI_OFF;    rcc_osc_init.HSEState = RCC_HSE_ON;    rcc_osc_init.PLL.PLLState = RCC_PLL_ON;  &nbsp

Hello community!I'm staging in a company and they let my program a conversor on my own, de issue is when I started with the UART communication. I need to analyse a message recieved by the user, so I need to be able to analyse any kind of message recieved without knowing the length and using HAL functions. I also need to do it without blocking the program, so it has to be done with interrupts.I have tried with HAL_UART_Receive_IT and combining HAL_UART_Receive with HAL_UART_IRQHandler but I got the same results. If there is any source would be a big help.Anticipated Thanks!(Sorry if my english is bad, i'm from a foreign country, if any aclaration is needed i'll be here)

Hi,After i remove the two 0Ω resistors (SB13 and SB14) by soldering iron, and then solder them onto SB62 and SB63 respectively, what can i do to used Usart 2 for ARDUINO interface? Thank

Hello, How to set RF SW CTRL pins? How to make them appear in platform settings of SUBGHZ_PHY configuration?

I can not find the STM32G473 evaluate board schematic drawing.

Hi @D.CedricalbanBased on your guidance on previous topic, i can execute python on raspi to read the tags.Currently, we would like to take the external MCU (like ESP32) as a host, implement it communicate with ST25RU3993-HPEV over UART. (please refer to my connection diagram : https://docs.google.com/presentation/d/1jLf4-6HVqBwT_gsOJ8EAMHpnaHdpxnHbBglNnPaBvNI/edit?usp=sharing)So, I would like confirm that is it possible to implement is that way ? if it is possible, any example can i refer ? i guess we can not use any example for the host in SDK for this case, because i saw example for host is base on POSIX or WIN32..thanksGreat to hear from you asap.

In stm32g030k6t6 mutiple adc channel working fine with DMA , But Not Working in Stm32g030c6t6.Kindly Help

Hi ST team and community!I am trying to develop a People Footfall Counter for commercial use using the two VL53L1X Sensors on Esp32 using the Sparkun Library from the following:https://github.com/sparkfun/SparkFun_VL53L1X_Arduino_LibraryFirst of all, I set two different addresses using XSHUT pins for the respective VL53L1X sensor. On calling getI2CAddress() function, I receive the set addresses again. But strangely, when i2c scanner code is executed(the i2c scanner code written just below the getI2CAddress()), I receive a single i2c address ie. 0X0B after scanning and not the assigned addresses of VL53L1X. Also it shows as 1 device found which is again strange as it should scan the VL53L1X Sensors as two separate entities since we have assigned two separate addresses. Please ignore address 0X68 as its of RTC.Since its for commercial use, I need the VL53L1X sensors to cover maximum area too. I get better output in ROI Configuration: x=8, y=8 and opticalCentre = {167, 223}. But when the

Have been struggling to get SPI to work. I have been working in the engineering boot mode to try and trouble shoot my issues. I have configured PLL3 to run the MCU at 48MHz and the SPI peripheral kernel clk to run at 108MHz and selected the clock sources in the RCC regs accordingly, I have implemented the procedure for configuring SPI in the related section in the reference manual. The GPIO have been configured to their appropriate modes and alternate functions. I have enabled the peripheral bus in RCC.I am able to confirm the register setting via the debugger.However, when I try to send data, I see nothing on the GPIO. I also don't see any flags reported when attempting to overfill the TXFIFO to elicit a response from the peripheral.I am not using the HAL library directly, though I have looked through it to see what I may have missed to no avail.Can anyone let me know if there is another enable bit, power bit or otherwise that I may be overlooking?

Hello.I'm beginner at programming and I'm trying do make Android app in Android studio that can read and write ST25DV64K, and I can't find appropriate libraries. Do you have some kind of source code for public that can help us?Thank you in advance.

So assume I define a text area widget which contained text "123". Can we have e.g. color gray for character '1', color black for character '2' and color red for character '3'?The usage is e.g. to take user input via numpad, and we want to show user which character has been edited, just edited and going to be edited accordingly.

I can run the code for the two cores if I program them separately from the Keil, but I would like to generate a .BIN image to send to my client, who is doing tests on a prototype, with the code for both cores.I generate the .BIN with the "fromelf" program but it doesn't seem to allow me to merge two AXF files into a single BIN.I tried to use "srec_cat" to merge the two .HEX but the resulting file, converted to .BIN, becomes a file of about 130MByte! Obviously I'm doing something wrong.Can someone please suggest me a way?Many ThanksClemente

I'm configuring i2c with dma using the registers directly. I'm sure I have an error somewhere but I don't have a great idea on where to go next with debugging. Sometimes my i2c transfer goes through expediently, but sometimes it has a long stall after the address portion. Currently dma is only being used for this one peripheral. In the below scope trace, the purple is a gpio set in my function where the dma is set up, followed by an i2c start. I don't see how it could wait for 60 us before sending the data. Does anyone have any ideas what might cause this or where to look?My i2c clock and apb clock are both set to 170 MHz. There is a note in the errata about i2c stall, but it doesn't seem to apply.

Hello,I have spent some time reading through the VL53L0X API and all documentation related to this sensor.I was hoping your team could clarify the usage of a few functions and features."Pre-Range" vs "Final-Range"This distinction is made througout the API, but the two are never actually defined. I was reading this document on TOF principles and on pg.37/38 it mentions a technique where the integration period is divided into two halves, each with a different frequency. Is that what Pre/Final refers to? This is my first guess since the VCSEL periods are split like this (i.e. 14/10 or 18/14).Scheduler Sequence StepsWhy are two of these disabled by default?Limit Checks:0: SIGMA_FINAL_RANGE (mm)1: SIGNAL_RATE_FINAL_RANGE (Mcps)2: SIGNAL_REF_CLIP (????)3: RANGE_IGNORE_THRESHOLD (Mcps/SPAD)4: SIGNAL_RATE_MSRC (Mcps)5: SIGNAL_RATE_PRE_RANGE (Mcps)What are the use cases for these, especially #2, #4, and #5? For RANGE_IGNORE_THRESHOLD, is this limit check meant to be a constant rate like the oth

Hi!I am operating on an STM32F446 chip and I have the following issue:I tested out a communication system where I attached a 912600 baud communication with another device via UART1 on a STM32f446 NUCLEO Board. All worked out well, no errors or other issues.Now we have designed a pcb with the stm32f446 chip, and is still running on 912600 baud via UART1. The issue is, now we have a communication-loss, after startup, no bytes can actually be read anymore in our serial port on UART1. I tried out 115200 Baud instead of 912600 and it fixes the problem. But I can not figure out why exactly. We have no oscillator attached on OSC32_IN and OSC32_OUT , only on OSC_IN and OSC_OUT we use an extern 20MHz crystal oscillator.I read the reference manual of the stm32f446 but I can't really understand what's meant by oversampling on page 810 - 816 and all the rest is also pretty hard to understand for me..Has the OSC32 a big impact on using a high baud rate like 912600 on UART1, or could I have missed s

Hello,I'm currently working on an application using STM32F105 uC.I want to use some GPIO as analog input, so I need to use the ADC converter.It seems that each channel is linked to one ADC channel. I have found some table with this mapping for other devices, but unfortunately I cannot find this table for this specific device.(I attach STM32F3 a equivalence table just for your reference.)With best regards,Didac

I am using 2 microcontrollers STM32F103ZETx as transmitter and STM32F730R8 as reciever. So my CAN is coming into initialization mode but has some issues in CAN normal mode. SLAK=0 , INAK=1(should be 0) and INRQ = 1(should be 0) for can normal mode.1.How to make INRQ =1 by software.What changes should I do to the code ?2.my DBF=1.Does it affect CAN normal mode ?I tried making INRQ =0 which made INAK=0 and SLAK =0 , but TERR became 1 , that is error occurred.Still TXOK was 0.

Similar kind of project is generated when the main sensor is Observer+PLL and auxiliary sensor as Hall Sensor. Now tried Hall sensor as main sensor, but error exists when building a project.
