Solved

Hello,I am currently interfacing ST25DV with STM32L073 MCU using lower level drivers for I2C instead of HAL drivers. I have successfully configured and tested the ST25DV FTM mode.Now i want to use the user memory region in ST25DV to store product information. So what should be the steps to write and read from the user memory (EEPROM) ? As per the docs, i have to disable the mailbox to have access to EEPROM. So i disabled the mailbox using dynamic register. Than opened I2C session by passing password. Using i2c write function tried writing a single byte to 0x0000 address but write function failed. When i try using HAL driver it gives me error code of 1. So can anyone please tell me the step for writing / reading from the user memory EEPROM in ST25DV04K.

Hi im trying to develop a bit of error management in my canbus driver.I noticed there is an ErrorCode inside the canbus structure. That error code could have any of these values:  But it turns out the hcan.ErrorCode is always HAL_CAN_ERROR_NONE, even if the canbus is not plugged to anything wich should give any of these://#define HAL_CAN_ERROR_EPV (0x00000002U) /*!< Error Passive */ //#define HAL_CAN_ERROR_BOF (0x00000004U) /*!< Bus-off error */  //#define HAL_CAN_ERROR_ACK (0x00000020U) /*!< Acknowledgment error */Am i missing something out here? maybe something needs to be enabled somewhere in the HAL to get errors¿

Hello Developers,I am currently working on a project that includes NFC communication using ST25R3911B-DISCO board and ST25DV NFC tags. The project also includes development of custom GUI application similar to STSW-ST25R001 software. Currently i am using STSW-ST25R001 PC software to communicate with ST25R3911B-DISCO board. But can any one let me know is there JAVA source code available for STSW-ST25R001 software ? And if yes please share the necessary links.

Hi, I am using the STM32CubeIDE version 1.9.0 Code Generator feature (via the CubeMX graphical interface) and wanted to generate the 96 MHz sample clock for the I2S codec. Unfortunately, I found that the code generated under sub "void SystemClock_Config(void)" missing the I2S clock setting which supposed to look something like below://all these are not generated by the CubeMX code generator RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};   ... PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_I2S; PeriphClkInitStruct.PLLI2S.PLLI2SN = 192; PeriphClkInitStruct.PLLI2S.PLLI2SR = 2; if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK) { Error_Handler(); }My question is:1) Am I missing anything while setting the CubeMX?2) What will be the way out other than copy the code above into my project main.c file?NOTE: I am comparing my code with respect to sample code given by other person then I know that the CubeMX Code Generator of my work lack of the above c

I am using the timer interrupt and currently, it has priority 3 once I get into the ISR then I want to change the priority to 2. I have used like below but the priority not changing.NVIC->IPR[6] |= NVIC_IPR6_PRI_25 & 0x22222222;__dsb(0);In above, __dsb(0) or __dsb(1) I am not getting?I am using the Keil environment.

When I configure a SWV data trace comparator with a variable name, it's working properly. If, instead of the variable name, I use its address (extracted from the map file, so I know it's correct), it doesn't work, I mean no data is printed out in the SWV Data Trace window and SWV Trace Log doesn't show any activity related to this.For this simple example, it would be fine to use the variable name but, for other situations, using the address is required as the IDE is not able to resolve the variable address.I'm currently using v1.9.0, I don't know if previous versions are showing the same issue.Any clue about that?

I have an STLINK-V3SET connected to a Seeed Lora-E5. I also have a Nucleo L476 developement board with on-board STLINK. On the Seeed board I am able to connect STM32CubeProgrammer and have loaded a file. I cannot connect however STM32CubeIDE as I get an immediate failure to connect due to GDB server ....On the Nucleo I have successfully connected the STM Utility and downloaded a file but once again I cannot connect STM32CubeIDE. I downloaded all three of these apps today so they are the latest....CubeIDE is 1.10.0. The IDE was working just fine as I have flashed Nucleol476 and NucleoWB boards but somehow I have corrupted it's ability to use the GDB server. I deleted the debug and .launch but to no avail....Please help here as I no longer have the ability to use the IDE ????? UPDATE:removed 1.10.0 IDE and went back to 1.9.0....Below is the message received as I tried to load the application and run it on a NucleoL476....it got farther than it has but still some sort of issue???? Fu

Dear all,I am using Cube MX to generate a template code for my new project. In Advanced Settings page under project manager tab, Init sub-routines order is not correct and I also cannot fix it. DMA is used in ADC1 and it should initialize before than ADC1_Init. However Cube MX puts ADC1_Init function before than DMA_Init. MX_ADC1_Init order also cannot be changed because order change buttons are not active. There is a problem with RCC section as well. I reported previously and ST said it is known issue and will be fixed. (https://community.st.com/s/question/0D53W00001Xuay2SAB/adc-clock-setting-in-st-cube-mx-for-stm32h742vgt). However I may find another problem. I genereted a template code using Cube MX and I realized some peripherals clock and PLLs are not set in PeriphCommonClock_Config subroutine. I am not sure whether it is a mistake but I believe it is. There is only settings for PLL3 and SPI123. I am using PLL2Q and some USARTs. Do you think it is a mistake and cube mx should gene

Hello, we are having trouble with our application binary size. Inspecting the binary, I noticed that TouchGFX frameBuf is stored in .data section, meaning that it takes about 150kB of flash space in addition to RAM space. Is it possible to store frameBuf in .bss so that flash space is not used? If I understand correctly, it could be initialized to just zero? According to documentation:> Use the section "TouchGFX_Framebuffer" in the linker to specify the placement of the buffer but I have not been successful trying to modify the linker script

I just downloaded both STM32CubeMX (windows) and en.stm32cubef4_v1-27-0.zip.When I try to install the F4 package, it ask me for confirmation of license, checks license,churns mightly for a long while, and finally says "Problem during Unzip".I confirmed I can unzip the file AOK and downloaded a 2nd time just to be sure.I tried letting CubeMX download and install the file, with same result.What's going on???Thanks,Best Regards, Dave

The problem is as follows: When I am trying to update HRTIM master timer registers (MPER, MCMP1-4) on the STM32G474 via Burst DMA access, every data word I write into the BDMADR register gets written into two of the specified master timer registers. So the first data word gets written into MPER and MCMP1, the second into MCMP2 and MCMP3, the third into MCMP4 and whatever has the address after MCMP4 (it's not a master timer register I think), and then it repeats. I have tried manually writing into the BDMADR register, used various DMA data chunk lengths, but to no avail.

I was working on a simple SPI transmit code, I am transmitting some string data via SPI Half duplex, the code is like I press blue button on the discovery board, and it transmits data, which I read from logic analyzer, but every time after data is transmitted, and I keep button pressed/release and press again, it also sends some garbage values after that, and keeps on doing that, I can't figure out what's wrong, pls find Code and Analyzer traces below*******************************CODE BELOW***********************************#include "main.h"/* Private includes ----------------------------------------------------------*//* USER CODE BEGIN Includes *//* USER CODE END Includes *//* Private typedef -----------------------------------------------------------*//* USER CODE BEGIN PTD *//* USER CODE END PTD *//* Private define ------------------------------------------------------------*//* USER CODE BEGIN PD *//* USER CODE END PD *//* Private macro -------------------------------------------

I have read a book on stm32, and inside the timer topic, it is stated that a formula to determine the values to be loaded to generate interrupt at specified times which as below:My question is does this formula applicable for all stm32 timers? and another question is, I could not find this formula in reference manual for model stm32L476RG. Could someone show me where to get this formula from official ST documentation?

Hello all, I am currently trying to get my STM32F411RE code working in Atollic TrueStudio. This project leverages the use of DMA and CMSIS-DSP which are all working in TrueStudio to find freqeuncy outcomes. The issues at hand is that I can upload my code to the STM32 board in the debug mode, but that this crashes once I attempt to resume the code and execute the main loop.I upload the code to the board using the ST32 Cubeprogrammer CLI, which downloads and verifies the code without any hiccups. It then switches over to the ST-Link which executes the setup code and stops at the (auto inserted per GDB) breakpoint just before the main. Executing the code then yields:TraceCaptureStart and SWV event set to APP_TRUE ST-LINK device status: RUN_MODE   ST-LINK device status: Failed to get status, Target not responding, retrying... Target is not responding, retrying....   ST-LINK device status: Failed to get status, Target not responding, retrying... Target is not responding, retrying.

Hello....I am using STM32CubeIDE 1.10.0. I purchased a LoRa-E5 from Seeed. The E5 has proprietary code on it that one must use a UART to talk to the device. I would like to basically erase the device and load my own code onto the device. I have created a very basic project in CubeIDE for the STM32WLE5JC which is the processor on the E5. At the moment my code does nothing more than toggle PA3 high and low. When I try to load the code onto the DUT I get the following error on the console:Erasing memory corresponding to segment 0:Erasing internal memory sectors [0 3]Download in Progress:Error: failed to download Segment[0]Error: failed to download the FileFurther reading seems to imply that the RPD bits are somehow set and I need to set them to Level 0. Can someone please confirm that yes this is actually the problem? And how using CubeIDE I go about doing this? I am very unfamiliar with this environment and would prefer to use CubeIDE rather than command line, etc. I was under the impres

Background:I have two STEVAL-IDB011V2 BlueNRG-LP boards. One of these evaluation boards is no longer recognized by MS Windows10 host machine at the serial port (i.e. Device Manager shows a problem with that USB device). As a result, the ST RF-Flash Utility (in fact, all of the ST Micro development software) cannot communicate with this board. Thus I have no easy way to reflash the firmware on this board.The last firmware I loaded on the malfunctioning board still communicates with my cell phone over BLE, so the Cortex M0 and BLE stack seem to be intact. However, it appears the circuitry associated with the UART is unhappy.The second evaluation board I have (identical hardware to the one that is malfunctioning) is recognized fine by the Windows10 host machine.Questions:Is there a way to recover the board, or am I going to have to purchase a new one?Has anyone seen this type of behavior in the past and how do I avoid this in the future? Thanks for any help or recommendations you can give

I'm working on a custom board based on STM32WLE5JB. First few prototypes worked without any issues, but in the last small batch (assembled by different assembly house) many boards have issues with data transmission: using HackRF I can see that the boards transmit something on the correct frequency (868.1, 868.3, 868.5MHz) but the gateway (RAK7258) doesn't detect it. Visually it looks like the transmitted signal on the bad boards is stronger so maybe it's somehow distorted (but it is slightly closer to the gateway so it's subjective).So, two boards from the same batch, running the same firmware, do the transmission but the gateway can decode only one.What would be the best way to debug this? Could this be the consequence of bad antenna matching (antenna was supposed be matched properly and boards are assembled in the same run so the components should be the same on them)?signal from ok board:signal from bad board:

I know that STM32H753 is pin-compatible to STM32H743, and as far as I know also code-compatible for most intents and purposes. The only difference seems to be the Crypto hardware acceleration. So I assume that I can run code from H743 on the H753 without even recompiling, is that correct?What about the Bootloader? AN2606 makes no distinction between H743 and H753, so again I assume the chips are interchangeable in this regard?What about the SecureBoot / SBSFU stuff? Do I need to do something special if I DON'T want to use these features? Or are they disabled by default?Thanks for your help!

In some situations, CubeIDE (v1.9.0) is not anymore able to handle the communication with the ST-Link probe. Disconnecting the USB cable, restarting CubeIDE, reseting the MCU, nothing allows to make it working again. The only way I found is restarding the computer, which is a bit tedious.Does somebody have a solution for that?
