Hi,I have two MCU communicating with each other via RS485. It's a very simple code one MCU send a data to other and the other is trying to receive this. With MCU2 code everything is fine. It sends data like it should be.Problem is with MCU1 code. When I delete #65 line in code (that one with HAL_UART_Transmit...) it works great. It receive data from MCU2 and starts engine and horn. But when I add this line it stop working. I dont understand why this is happening.When the MCU2 works as a receiver everything is ok, but when I try to send something from it suddenly the whole uart stops working MCU1 code:/* USER CODE BEGIN 0 */ uint8_t buffer[2]; uint8_t ZERO[2]={0x00,0x00}; uint8_t AA[2]={0xAA,0xAA}; uint8_t BB[2]={0xBB,0xBB}; void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { if(buffer[0]==0xCC && buffer[1]==0xCC) { Engine(ON); } if(buffer[0]==0xDD && buffer[1]==0xDD) { Horn(ON); } HAL_UART_Receive_IT(&huart2, buffer, 2); } /* USER CODE EN

Hi,I'm willing to use the MXCHIP EMW3080B wireless module on the B-U585I-IOT02A in a project with TrustZone enabled. As there is no tutorial for that, I copied files from the Nx_Network_Basics example.Unfortunately I get the following error when building the Non-Secure project: unknown type name 'noos_queue_t'Your help will be much appreciated, thanks!@Benjamin BARATTE @STea 

Hello,I have a scenario where RFID tags may be presented to a ST25R3911 reader at any orientation.Tags do not read If the plane of the tag antenna is not properly aligned enough with the plane of the reader antenna.To work around this, I was thinking of using two ST25R3911's with antennas perpendicular or at some angle to each other with the idea that at least one reader antenna will pick up the tag.The questions I have are:1. Is this a feasible solution ?2. Can the two readers be active at the same time or should only one reader be active at a time ?3. I understand that the ST25R3911 can have two antennas, would this be a better solution than having two ST25R3911's ?4. Is there a better solution ?Thanks for any suggestions, I am new to RFID.-Randy        

I am using stm32h743 mcu and initialized cdc usb fs with cube mx for device only. After that i changed  descriptors of cdc with uvc descriptors now the device is recognized as usb composite device on device manager but i am not able to transmit any data over it as i tried to send dummy data but no packets were sent as i monitored them on wireshark. 

Hello,I am trying to bring up my custom board with STM32MP157F largely inspired by STM32MP157F-DK2 board but with a dual RAM configuration.I am having a Panic error after ROM boot which states in the line before an error related to "fdt_counter_get", a function that I have no idea what it does and I cannot seem to find where it comes from, anywhere on internet or in my files.I have looked at the usual troobleshooting guidelines and I have no difference with discovery kit devictree configuration regarding HSE (oscillator bypass), I2C4 and PMIC (although I removed some unused configuration for HDMI or audio which I do not have in my board).Here are the logs I get on UART console during boot.

hello, I have a display configured for FMC but I would like to add a framebuffer to the RAM memory, unfortunately the MCU memory is not enough (the display resolution is 480x800) so I have to add external RAM. My question is how to do it since I am already using FMC for the display. Can I connect RAM to the same pins?

I'm working on stm32wl55 Nucleo-64.I have doubts regarding the mechanism by which the duty cycle control is implemented in the project.I am sending a test LoRa message with a payload of 231 Bytes, using DR5 and SF7 every 10 seconds (whereas a 1% duty cycle should enforce a retransmission approximately every 36 seconds).What happens is highlighted by the log below:###### ========== MCPS-Confirm =============###### U/L FRAME:0042 | PORT:10 | DR:5 | PWR:7 | MSG TYPE:UNCONFIRMED450s717:TX on freq 868100000 Hz at DR 5450s725:SEND REQUEST451s109:MAC txDone451s110:RX_C on freq 869525000 Hz at DR 0456s086:RX_1 on freq 868100000 Hz at DR 5456s133:IRQ_RX_TX_TIMEOUT456s133:MAC rxTimeOut456s133:RX_C on freq 869525000 Hz at DR 0457s137:RX_2 on freq 869525000 Hz at DR 0457s335:IRQ_RX_TX_TIMEOUT457s335:MAC rxTimeOut457s335:RX_C on freq 869525000 Hz at DR 0###### ========== MCPS-Confirm =============###### U/L FRAME:0043 | PORT:10 | DR:5 | PWR:7 | MSG TYPE:UNCONFIRMED460s725:TX on freq 868500000 Hz at

Hello everyone, I am a student who is fairly new to these concepts so I wanted to pick your brains for a bit if you'll allow me to. I have done some research and found that STM32F4 is compatible with AT commands if we use external hardware. However, I am stuck on what to use. ESP8266 and ESP32 seem like fairly popular choices. I also researched and found that good alternatives for those are: nRF52840, C3200, CC3220. Then I found out about SoCs (system on chip) but I think that is a bit too advanced for a beginner, I'll try those out when I have grown more familiar with this. Thank you for any and all of your help, as well as for your time!

Recently I brought FEIG CPR30Pro to automate our ST25 NFC testing process.But after installing STSW-ST25PC001 & STSW-ST25PC002 application from below linkhttps://www.st.com/en/embedded-software/stsw-st25pc001.html#overviewnot able to connect FEIG CPR30pro reader. Pop up displayed as It support FEIG CPR30 and FEIG CPR30+ models but not FEIGCPR30pro.Can you please suggest me how can I use it over PC for testing ST25 NFC Tags using FEIGCPR30pro?

Hello:I am looking for a fast way to add an array of data to a static graph without adding them one point at a time using addDataPoint(). I also don't care about the x values. They are just sequential. I want to update the entire graph at once and then refresh the display. Is there a way to do this?Thanks,Dan 

Following the instructions on the wiki page for getting started, the board does not appear over USB and cannot be recognised by STM32CubeProgrammer. Green power LED is on. Switches are in correct position. STLink is red light is blinking. Power rails seem fine, although DDR is 0 volts. I have tried two different computers, one Linux, one macOS and neither can detect the USB device or connect to it from STM32CubeProgrammer. I have also tried different cables.

Hello,I have installed STM32CubeProgrammer (version 2.14.0) on a Linux machine. I have connected my NUCLEO-U575ZI-Q microcontroller to the machine, but the CubeProgrammer does not detect it (the machine does). I received this message on the CubeProgrammer:ST-LINK error (DEV_CONNECT_ERR)I tried the same setup on a Windows PC and it worked perfectly (with the same version of CubeProgrammer).What could be the possible solution?Best regards,

Hello Everyone,I have a problem. I am doing some testing with an STM32f429I board. My project involves controlling several peripherals. Now what I would like to ask is, once I have created a TouchGFX graphic with all the interactions and various pages, how do I integrate it into my pre-existing project on CubeIDE without upsetting everything?I already have TouchGFX enabled in the software package. I would like to physically figure out how to move the graphic from the project that GFX creates for me to my own. Then I will figure out how to implement the functions for the interactions in the graphics.ThanksTranslated with DeepL.com (free version)

Hi,     I am currently using STM32H5 series, to transmit the RTC register content to an escalator base board. I need to transmit these data in a parallel manner (i.e. MCU act as a slave and the base board act as a master). I studied that STM32H5 series has PSSI which involves a data bus (PSSI_D[15:0]), data enable (PSSI_DE) and ready bit (PSSI_RDY) and a clock (PSSI_PDCK). Where the signal comes from the base boards are address and data lines (PMD<7:0>), chip select (PMCSx), read (PMRD) and write signal (PMWR).A 4-bit address is transmit to the MCU (slave) from the base board (master). The MCU needs to place the data in the data bus as shown in the Figure 4-1. Is it possible to implement this in STM32H5 series? If not then suggests me some other STM MCUs with the following specifications:1. Dimension between (5mmx5mm) to (9mmx9mm)2. Pin count between 32 to 643. Package - Any package except ball grid array Your help and advice much appreciated.

BACKROUND:I am using TouchGFX Designer - 4.24.0I am using the board STM32H735G-DKThis generates STM projects in STM32CubeMX V6.11.0 using STM32Cube FW_H7_V1.11.1When I am done with touchGFX I go to STM32Cube IDE to do some scripting on the behaviors of the GUI.When I open the .IOC file for the first time I am prompted with a message that wants me to migrate my project to STM32CubeMX V6.11.1 using STM32Cube FW_H7_V1.11.2PROBLEM:If I say no to the migration and I attempt to give a "job"(EX: GPIO output) to a pin then generate code it will not correctly generate code in the main.c file. A few forums talked about the main.h or gpio.c and I look into those with no luck either. If I run the program the basic GUI set up in TouchGFX appears on the screenIf I say yes it works! All the correct code is generated correctly in the main.c file. When I attempt to run the program it executes very fast and displays a black screen after it finishes executing. No error messages occur.EXTRANOTES:I am

Hello guys! we generally configures UART in the cube mx and generating the codes, and after by calling Transmit and Recieve functions we are checking the outs on serial terminals.. if we dont get desired outputs then we are trying to dubbug and testing the hardware and observing the frames on CROs.For most of the software engineers operating CROs is a headache. thats why i was thinking to build Selt test code in that it should verify the UART initialization is configured properly or not as well as it should check the configured baudrate is generating correctly or not by getting feedback on some other GPIOs.  

According the the Lora Logo guide from Semtech, one can apply on the use of the logo if one is using a RF IC of Semtech. https://blog.semtech.com/how-to-name-and-brand-your-lora-applicationDoes this also hold true for the STM32WLE which integrates Semtech technology?

Hello, I am working with RAK3172 which has STM32WLE5CCU6, from CubeMX I am enabling it's SUBGHZ_Phy functionality. But after code generation I am seeing there are two files "app_subghz_phy" and "subghz_phy_app", what are the differences between these two? Which files needs to be modified if I want to control the radio layer? Thank you.

I can remember that the Project Manager tab of the STM32CubeIDE showed an option to change the used firmware package. In my current project I'm not able to do that. When opening the .ioc file the used FW package is version 1.17.3, while the IDE actually has version 1.18 installed already.Is this some kind of bug? Or intended behaviour? How do I change the project to use the latest FW for the MCU?I just noticed it in IDE version 1.14, but an update to the current vresion 1.15 did not change it. 

Hello!I'm quite new to this, so I hope I'm providing enough information. I have successfully run a DS18B20 temperature sensor on a Nucleo L476RG and written the temperature to the tag of the NFC07A1. However, this only works while it's connected to a power source. Now, I have an NFC08A1 on a Nucleo F746ZG, and I want it to power the sensor (and on a next step read the temperature from the sensor).When I run the Energy Harvesting (EH), I get approximately +/- 2.5 V on the tag part, which isn't even enough to light the green LED of the NFC07A1 fully.On the reader/source side, I'm running the demo PollingTagDetect_NDEF.Could anyone provide some advice on what I might be doing wrong, or let me know if you need any other information to assist me?Thank you in advance,Kris 

Hello, I have designed my PCB with stm32f427VIT6 and a 24Mhz crystal oscillator. I was trying to upload and test the normal blink code and it's not working. If I disable the external clock, the LED works and does not work with an external clock. I am completely new to STM, I did not know exactly whether I messed up with the design or could not configure the clock properly. I am attaching the schematics of my connection and a screenshot of the clock configuration that I have tried. Kindly help me :)   

Hi I am luis.I'm testing TouchGFX, and I have a question.After creating an example board project with TouchGFX V4.22.1 Designer and then moving the STM32F769I_DISCO.ioc file into the STM32CubeIDE folder to set the IO, an error occurs when compiling after setting the IO. There are too many errors to easily resolve. I would like to know what is the optimal way to set up IO after creating a project with TouchGFX V4.22.1 Designer. 

I am using the STEVAL-STWINBX1 development board and have downloaded the FP-SNS-DATALOG2 software to the board. When I use the board in stand alone mode, the data is saved to the SD card and the folders are sequentially named as DL2_00001, DL2_00002, DL2_00003 etc. When the board is connected via USB to a computer, the data is streamed and saved to to the computer and the folders are named with the year/month/date/time (YYYYMMDD_HH_MM_SS). Is there anyway to name the folders with the year/month/date/time (YYYYMMDD_HH_MM_SS) when using the board in stand alone mode and logging to the SD card ?  Whether that means implementing a real time clock or receiving a UNIX time from some external source ? I need to synchronize the data logs from different DAQ systems including the STEVAL-STWINBX1, so a folder named with year/month/date/time is a requirement. Note: This also relates to my post about synchronizing different DAQ systems... https://commun
