Solved

and build analyzer is showing those memory regions. I did not have this problem before. The new project name is AC_2 which is changed from AC_1. Now under build analyzer I see AC_1.elf/AC_2/Debug -27th August -2022, 6:33:40 PM. When I expand the projects tab and under Debug I see only AC_1.elf -[arm/le] though in the folder I see AC_2.elf. It is important for me to know the memory usage for my current project. Can someone help me please? This is a bit urgent and request your help ASAP. Appreciate your time and help. Thank you.

I'm using STM32F105R8T to send serial buffer commands to an HMI display.MAX485 chip was used for communication. There are pre-defined command buffers and updatable data buffers. Those buffers are sent through a RS485 bus at the baud rate of 9600. There are lots of commands that I should send to operate the display. I'm using 50ms time interrupt for data transmission. MCU doesn't output correct buffers when there is large amount of data, and it causes to error in the display. When I check HAL_UART_Transmit function, It begins busy sometimes, and it doesn't want to transmit data. What are the solutions that I can get to drive this display smoothly.ThanksHere's my Codehttps://github.com/akilawickramasinghe/Vega_ETX_Display_Firmware_V2

 I am using Linux Linux kubuntu 22.10 5.19.0-26-generic and when I click on the GPIO Pull-up/Pull-down column elements nothing happens except the color of the row changes.

When I configure SPI2 in STM32CubeMX, I see the following:Here, I'm set up as a full-duplex SPI master, the prescaler is set to 8 and underneath the prescaler specification, it computes the baud rate to be 2 MBits/s. I've also observed that this value does not change with processor clock frequency so the tool must be assuming that the input clock is from the SPI2S2 clock multiplexor. This is consistent with what I see in STM32CubeMX because if I vary this clock with the PLL, the baud rate tracks this frequency. SPI1 works as expectedI ran some code that performs SPI transactions and observed the following on the logic analyzer:Clearly, the SPI baud rate is 4 MBits/s and not the 2 MBits/s as computed by the tool.From this, I conclude that the clock source for SPI is actually PCLK1 and not the output of the SPI2S2 clock multiplexor. I think that that clock is only used in I2S mode (which I've never used) which is suggested by the reference manual in section 7.4.29 for bits 9:8:"This bit

Can I write single bit to EEPROM and count it as 1/8 of write cycle of 100k EEPROM write cycles in case of internal stm32l073 EEPROM? Hello, When I clear eeprom byte to 0xff I count it as single clear. Now when I write value to this byte I count it as single write. So according to RM I have 100k of safe read write operations like that. Can I assume that writting single bit to this byte is one eighth of this write operation? so:Perform clear = byte is equal to 0xffWrite 0x7F = clear MSbWrite 0x3F = clear nex bitand so onwrite 0x01 = only one bit leftwrite 0x00 = whole byte is cleared. Can I assume above procedure as single clear/write cycle? And safely execute 100k times? I need to count and store 100000000 events in system (number of them). By using 8 bits for 100k cycles I only need 125 bytes to track those events. If I use uint32_t to store that I would have to use 4MB to safely store that event counter. I cant find in documentation if when I write

Hi team,I'm developing a PCB that implements STM32MP151AAA3.I think VBAT is a backup power supply for RTC, so I'm planning to supply power to VBAT from a button battery.Will the RTC be reset when this button battery is changed?If it is so, is there any way to avoid resetting, such as connecting a capacitor on the VBAT input terminal?Best regards,

Hello everyone, I want to ask what is the best way to save data. I understand that I need to use Model to save. I am kind a new in c++ programming so maybe there is a way to save data in model structs? Can someone help me?for example I want to save all these selected text to model:I'm using functions which goes to presenter and when save to model. But I save this texts one by one and it becomes mess. In my project will be a lot of configuration data and I need to somehow save it.

to see my data on python what library or code should I use in STM32(CubeIDE) ? Could you share with me example!

This initially an azrtos tx toggle LED test on a STM32F4Discovery boardI followed this videoMOOC - Azure RTOS workshop - 5 ThreadX lab - step1 - First thread creation - YouTubeThe attached fileSTM32F4DISCO-1.10.1 works when compile with 1.10.1After further debug with 1.11.0 it turns outs the attached STM32F4Disco-Dec2022 file crashes in HAL_INIT() because TIM6_DAC_IRQHandler() isn't generated in stm32f4xx_it.c.

Hello, Why the NUCLEO-F446RE board isn't available in MotorControl Workbench 6.0.0?It was available in MotorControl Workbench 5.4.8.For motor control the recommendation is to use the STM32G microcontrollers?Thanks for your support!

Hi, I have been reading about this module (Teseo-LIV3F) and this IC (STA8089FG), as I can see both offers almost the same characteristics and both need external circuits to connect an antenna, so in which case should I use one or another?, why the module is shielded and the IC is unshielded?, I thought that all the RF components must be shielded but this is a case where I think I was wrongThanks

Hi,USB DFU did not work in STM32CubeProgrammer in Linux. The programm did not detect the usb port. But it works faultless in STM32CubeProgrammer in windows.I tested with STM32CubeProgrammer V2.10 and 2.12, same results.I have linux mint 20.3 Luna

Could some one tell me explain why ?

Hi there, I have tried BLE_HeartRate_ota and it works. Yet, when I integrate OTA to my own applicaiton (by uploading BLE_Ota_reference.hex to 0x08000000 first)and try to update the firmware via ST BLE sensor app, the STM_OTA service cannot be connected and the app shows that node cannot be found. Only my application is advertising. My application starts at 08007000 and I have updated the linker file(you can find it in the attachment). "BLE_CFG_OTA_REBOOT_CHAR"  is set to 1 (from ble.config.h) and "SCB->VTOR = VECT_TAB_OFFSET" is removed (from system_stm32wbxx.c). The magic word can be found in app_ble.c(see below). I am using STM32cubeIDE and STM32Cube_FW_WB_V1.0.0. I have no idea what to do so that my OTA application can work. Thank you for any suggestion!Cheers,Mo

Hello!I have faced the problem with ADC checking using DMA on my F446RET6 MCU. The software tools are CubeMX 6.7.0 and CubeIDE 1.10.1. The Firmware is FW4_1.27.1. Perhaps, it is my mistake, but i canntot understand how to fix it. Here is the simple project directory in cubeIDE https://www.dropbox.com/s/g1o8yunmubjjmk1/F446_ADC_DMA.zip?dl=0 together with .ioc file.After HAL_ADC_Start_DMA(&hadc3, (uint32_t*)c_buff, ADC_CCONV); call there is no HAL_ADC_ConvCpltCallback() interrupt, yet i could not capture the interrupt inside the standard DMA2_Stream0_IRQHandler().Looking forward for your advice.

Hi,Could anyone help us find the right NFC IC for our application?Our team is developing a FIDO2 authenticator that should support the CTAP 2.0 NFC transport binding found in the CTAP 2.0 January 30 specification (I'm not allowed to post links as a new member to this forum).Out current hardware has the M24SR IC and we're in doubt that this IC works for our product.We need an IC that has support for data transport over NFC. We need to be able to take commands in the ISO7816 APDU format as well as Java Applet installation commands and pipeline that data through our MCU to a secure element. We also need to send data over NFC from our MCU.Kind regards,Benjamin

I am having trouble with the ClickListener. I am trying to debounce the click event somehow. My first instinct is to delay and then check to see if the click is still present, but I am not sure it will work with this function because it seems that the click is an event that is triggered. For example, here is one of my click hander calls:void MainView::circleClickHandler(const touchgfx::Circle& c, const ClickEvent& evt) {Any suggestions on what the proper way to debounce a ClickListener object is? The buttons that are built-in widgets seem to do this with no additional code. Thanks in advance!P.S. - programming with the STM32F469I-DISCO board.

Hello,I'm trying to send data to STM32 from NodeMCU. My project is simply controlling WS2812B LEDs by using SPI from STM32 and receiving commands by using UART to STM32 from NodeMCU. LED's working fine by SPI but I can only receive data once at start. Then UART stops. I can still send commands to nodeMCU but it doesn't transmit to STM32 after first command.What might cause this problem? Here is my SPI and UART settinghspi1.Instance = SPI1; hspi1.Init.Mode = SPI_MODE_MASTER; hspi1.Init.Direction = SPI_DIRECTION_2LINES; hspi1.Init.DataSize = SPI_DATASIZE_8BIT; hspi1.Init.CLKPolarity = SPI_POLARITY_LOW; hspi1.Init.CLKPhase = SPI_PHASE_1EDGE; hspi1.Init.NSS = SPI_NSS_SOFT; hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_16; hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB; hspi1.Init.TIMode = SPI_TIMODE_DISABLE; hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE; hspi1.Init.CRCPolynomial = 7; hspi1.Init.CRCLength = SPI_CRC_LENGTH_DATASIZE; hspi1.Init.NSSPMode = SPI_NSS_PULSE_DI

PC12, PC13 => A specific PORT is the input signal (Base) of the PNP Transitor-applied switching circuit, and functions to turn on (High) and turn off (Low) the LED.Please review the attached circuit diagram and PCB.Thank you.

I am using the ST25RU3993-EVAL board and its software GUI to read data from RFID-Tag ( Andy100 more informations in the Data-Sheet below). The tag can communicate with external devices (sensors/ external storage units) via spi. The SPI-Commands can be sent from the reader via rfid-waves. I am struggling to send commands to read/write data from/on an EEPROM (which is connected to the Tag via spi), because of lack of documentation on the structure of the commands sent by the reader. All i have from the user manual of ST25RU3993 evaluation board software GUI is an example of generic command about reading the first word in TID memory from address 0. I have tried to modify this command to access the memory address I am aiming to read (I have written some numbers in these addresses) but I am still getting some random numbers every time. I hope somebody could help me with it.Here are datasheets of the RFID-Tag ( IC and PCB) and the EEPROM (M95010-RDW6TP) I am using.

Hello everyone,I work on a project with STM32L072CBT6.I want to use a DMA RX on LPUART1, after reading differents ressources i have setup my LPUART and my DMA.I want to receive an interrupt from my DMA when transmit IDLE (end of transmit).My problem is the following, when i download my firmware and check my debug, no interrupt are flaged. When i power down/up my card, my interrupt work only once.I have try differents things but i have obtain no result.I would like to know if you have advice that can help me about this problem ?Thanks for your help,Best regards,MLamDMA ConfigurationLPUART1 ConfigurationNVIC Configuration
