HelloI am encountering an issue with a code running on an STM32F4xxx board. The code is designed to perform a measurement, and I aim to transfer this data to a computer. While I can successfully receive the measurement using various terminal programs, I require the data to be imported into an Excel sheet. To facilitate this, I've developed a macro that extracts data from the serial interface.However, I've encountered a problem where the data from the ST Link Virtual COM port isn't being received by Excel VBA, despite ensuring that all settings such as baud rate, parity, stop bits, and flow control are correctly configured.Concurrently, I've conducted a test using an Arduino, where I've programmed it to transmit identical data (excluding measurements, which remain constant). Interestingly, when I switch the COM port to that of the Arduino, Excel successfully receives the data.This leads me to speculate whether there's a discrepancy between the virtual COM port of the STM32F4 Nucleo boar

How does one go about setting main() to address 8?Or any address, but I thought I'd be specific so I can see what the mechansim is to set things to specific addresses.  If you have a map input file (I see the out.map).Also, getting error:c:/spc5studio-6.0/eclipse/plugins/com.st.tools.spc5.tools.gnu.gcc.ppcvle.win32_4.9.4.20200908161514/toolchain/bin/../lib/gcc/powerpc-eabivle/4.9.4/../../../../powerpc-eabivle/bin/real-ld.exe: build/out.elf section `.bss' will not fit in region `ram'c:/spc5studio-6.0/eclipse/plugins/com.st.tools.spc5.tools.gnu.gcc.ppcvle.win32_4.9.4.20200908161514/toolchain/bin/../lib/gcc/powerpc-eabivle/4.9.4/../../../../powerpc-eabivle/bin/real-ld.exe: region `ram' overflowed by 3792 bytesNo idea where to look for the problem or how to correct.  Not new to embedded software and this is usually in some sort of linker file etc..usually can fix these things by a descriptive output file that fully describes the location and sizes of the code...but where...hmmm w

Hi everyone,I am currently designing my own PCB board using the bluenrg-332ac chip. I want to use the ufl/SMA port to connect my antenna without connecting the PCB antenna. So I wonder how to remove the PCB antenna from the PCB layout with only UFL port? as the PCB guideline didn't show me how to configure the matching network for the UFL port.Also, the current ufl port on the eval board is only for testing the chip's functionality and has a very low RSSI, which makes the signal too weak to be used. Thank you.Reference files: AN5526  STEVAL-IDB012V1  

The Discovery kit with STM32H745XI MCU outputs a triangle wave, but how can I make it output a sawtooth wave instead of a triangle wave?Please let me know the specific improvement and source code.Looking forward to your answer.

HiI'm working with SPC570 and SPC5 Studio, version: 5.8.1 with installed the SPC5Studio patch for DMA in SPC570S DSPI lld running on Windows 11. Very often I have a problem with Generate SPC5 Application because at the end of generation (that seems terminated with success), when I try the build SPC5 application I have these error: make -j4 allCompiling boot.sCompiling crt0.sCompiling vectors.sCompiling ivor.sAssembler messages:Fatal error: can't create build/obj/boot.o: No such file or directorymake: *** [build/obj/boot.o] Error 1make: *** Waiting for unfinished jobs....Assembler messages:Fatal error: can't create build/obj/vectors.o: No such file or directoryAssembler messages:Fatal error: can't create build/obj/crt0.o: No such file or directorymake: *** [build/obj/vectors.o] Error 1make: *** [build/obj/crt0.o] Error 1Assembler messages:Fatal error: can't create build/obj/ivor.o: No such file or directorymake: *** [build/obj/ivor.o] Error 115:51:05 Build Finished (

Dear Friends at Community;I am looking for the Excel file containing the register map for the L9961. I noticed it was not attached previously, although the revision history in the datasheet mentions that it was reattached in the latest version. Unfortunately, I cannot access it. Can you provide any assistance?Best Regards,Mohamed Smaili 

Hey. I tried to setup `printf` using the following forum post. I am using the `NUCLEO-L4A6ZG`.Here what I've tried so far. I connected the `USART2` to the Pins `PA2` (RX) and `PA3` (TX):(By default LPUART1 was configured and connected to PG7/8, since the forum post used USART2 I used it as well.)After the configuration was saved, and the code generated, I used the code from the previous mentioned forum post. Here a shorter and with comments removed version:  /* Includes ------------------------------------------------------------------*/ #include "main.h" #include "stdio.h" // ... /* Private variables ---------------------------------------------------------*/ UART_HandleTypeDef huart2; // ... /* Private function prototypes -----------------------------------------------*/ void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_USB_OTG_FS_PCD_Init(void); static void MX_USART2_UART_Init(void); /* USER CODE BEGIN PFP */ #define PUTCHAR_PROTOTYPE int _

Hello,  I am trying to compare a third party libraries size on my STM32 project.  Methodology  Firstly, i build a project without including a third party library and build it.  Secondly i build a project after including a third party library and compare memory usage with build analyzer and surprisingly i get the same result. How i can know the exact memory size used by library?  i used below libraries.   No. 1 Micro CBOR JavaScript 2 NanoCBOR C 3 QCBOR C 4 TinyCBOR C 5 libCBOR C   Without Library build project.    

I couldn't look at the registers while using Keil. The chip model is STM32U575VGT6. I remember the wrong package to install stm32U5, he said there was a file error, but I could still compile the U5 series chips. Is it because of this? now how do I install the package correctly. Attached are some picture descriptions

Hi,Why does this enum (in rfal_nfcv.h) do not contain the command code for some commands (eg:- Write AFI, Lock AFI etc )? I also do not see an api to do this -  If I need to write to AFI, Am I supposed to use directly api rfalNfcvPollerTransceiveReq() with 0x27h command code ?@Brian TIDAL  

Hello,I am using the NUCLEO-G071RB and the X-NUCLEO-DRP1M1 with the X-CUBE TXPP Software Bundle.I created my project via the instructions from https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Getting_started_with_USB-Power_Delivery_Dual_Role.Everything works fine.I have a case where my device is always a sink but has to change Data Role. Is there a way to read the data role via the stack? I know that there is a defualt power role, which basically sets the Data Role ( Sink = UFP). And if there is a Data Role Swap Request I could just chnge my variable.Depending ont he Data Role I need to set a ID.But is there a "nicer" way to read the Data Role from the Stack?Thanks in advance.

I am trying to run BDMA on STM32H7B3 in double buffering mode. During debugging, I can see that some registers are missing in BDMA->CCRx. According to the documentation, DBM should be located at position 15 and CT at position 16. Where can I download the corrected STM32H7B3.svd file?

Hello,For our battery-powered smoke extraction fans, we want to develop a brushless motor driver 1.5KW.For this new development we use the reference STSPIN32G4.I use a custom EVSPIN32G4 circuit board with a 4 pole pairs brushless motor equipped with hall sensors.I use MC workbench 6.2.1 for the application.We have a product who work fine with the software configuration in hall sensors.Today we want to migrate this application (fan application) in sensorless mode. in sensorless mode, I am encountering some difficulties:About 1 in 20 starts goes wrong and ends up with a speed fedback error, the other 19 starts happen normally. I would like to have advice on finding the right setting knowing that I have already followed your recommendations in your various supports. I have tested : different value for the regulator settings, different value for Pll ki and G2 value. Here is a description of the malfunction: Each time the speed feedback error appears, the propeller of my fan is st

Hey, i am developing a RFID reader for ISO-14443-4 card with st25r3917b. The firmware is done and works with my custom MCU board connected with external RF board of STEVAL-25R3916B. However , if I switching the testboard and connect with my custom RFID board ,the reader just can not detect the card .It is obviously cause by wrong matching circuit I draw before.The antenna parameter to the Antenna matching tool is still a question for me to implement a custom antenna for the project.Due to lacking of newwork analyzer and imformation from the antenna datasheet. Some of the parameter from the Antenna Matching tool is still missing(Target Q , Targeting Matching Z, Parallel resistance and the present box?). Should i just enter some general numbers in the blank? In my test , there are three board , one main board only contain MCU(STM32L452CCU6), one STEVAL-25R3916B RF board and one custom st25r3917b board contain RFID antenna with cable(FXR.01.07.0100C.A). In the Antenna Matching tool ,

Hi all, We have integrated an LIS2MDL magnetometer into our custom PCB. We have recently been running some tests on the boards, and are collection raw data from the sensor via the I2C line. In our testing, we have found that different boards appear to be outputting different raw values in what should be the same conditions. What we have done is taken the raw data from the devices, calculated the magnitude ( sqrt(mag_x^2 + mag_y^2 + mag_z^2) ) which provides the following pieces of information. All devices are placed in the exact same location in the exact same orientation when the data is recorded. Values are in LSBs, where 1LSB = 1.5 mG: DeviceX DirectionY DirectionZ Direction Magnitude# 1-3-15358163# 2126-218454519# 3132-315211404# 4262-376325561 We have been testing the devices with various paramagnetic and ferromagnetic materials, so I'm wondering if there was some sort of bias introduced that I am unaware of. Regardless, I am looking for some explanation a
