Hello,I would like to make communicating power converters that I can program with Simulink. I use several NUCLEO G474RE and when I configure them with CubeMX I can enable FDCANs but not CANs. The problem is that in the Simulink library there are CANs blocks and not FDCANs, hence I can't find how to link my Simulink blocks to the FDCAN I enabled.Does anyone know a way to bypass this problem?Thanks in advance.

Hi.i uses matlab2019 and i want to design software using simulink.but, when i add "GPIO_WRITE STM32", simulink generates this error. did you know about this error? and solution?

Hello, i just implemented the EEPROM Emulation example. It worked a few days perfectly. The i added a ADC via CubeMX. Now i always enter the hard fault handler after EE_Init() was called. Any idea? Thanks a lot

I am just getting one error and it dosent seem to go.Can anyone help me to figure out why this error is coming and help me to resolve it asap.I have attached a screenshot of the same for the refrence below.

Which optimization level do you set for final project? And my you know what is "Optimize for time" in keil?

I would compile the firmware STM32072 for the STM32L152 Discovery with TrueStudio. Ihave got the fatal error: tsl_acq_stm32l1xx_sw.h: No such file or directory

Hi all,I am working on a project using my Nucleo-H743 board and the project compile without errors but i have a lot of warning like this :0 errors and 36 warnings all the same "__Packed__" does not apply here Any ideas ?Thank you.

Please, can you help me on how to solve the problem with the flash Loader Demonstrator, recent I purchase Stm32f103c8 which I wanted to use Arduino IDE to embed the blue pill but the flash demo always showing (no response from the target, the boot loader can not be started. Please, verify the boot mode configuration and the flash protection status. Reset your device then try again)I checked all my connection it's Okay as mush of the YouTubers had described PA10 to TXDPA9  to RXD3V3  to 3.3VGND to GNDand my boot jumpers are Boot0 to 1I used both TTL and FT232 all keep showing the same. I will really appreciate it if you can help me out. here attached is the screenshot of my case. thank you in advance.

I am using custom board with STM32F373C8.IDE- Keil 5.29.STM32Cubemx - 6.2.0STM32F0 Discovery board is used to flash the program into my board.I am trying to write simple LED blinking code. Code works fine.But when I am downloading it to my board it doesn't et automatically reset . I have to give hardware reset.Thanks in advance....

Hello,I try to connect on a running target (an STM32L072CZ) for debug purpose with the Atollic True Studio 9.3.0 and a Jlink probe from Segger, but unfortunately, a reset occur at connection and I can't get the firmware context for debugging. I have followed the steps from chapter "ATTACH TO RUNNING TARGET USING SEGGER PROBE" from the AtollicTrueSTUDIOforSTM32UserGuide (creating a specific debug target with an empty "startup script" tab) but it does not work on my side. Where may I be wrong ?

I am developing a bare-metal project using the stm32F103 MCU, under Keil Uvision IDE,I am not able to print the float values (from the temperature sensor), but it works fine with an integer.Is there a method to use ,? I tried to implement another printf library but it doesn't work with float.I have no option to select float value in my IDE as shown in the image.Thank you.

I tried to use DSP CMSIS Library, I included the libraries and adjusted the Paths and Symbols but when I tried to build the program I get this notification.Cannot run program "arm-atollic-eabi-gcc": Command line too longHow I fix this problem ?

when i press debug button Target Software Startup Script Error comes.there is no change in startup script file it is by default.so what is the problem and how to solve it?

Hello, I would like to create new project for STM32G474 in Atollic Truestudio 9.3 but I can't choose in Target my microcontroller. Atollic TruseStudio don't support those microcontroller?I use STM32G474 - nucleo board. I can't choose any STM32G familly. I can see microcontrollers like STM32H7, STM32F7, STM32G0 etc.. but not STM32G4. Does anyone know what I'm doing wrong?

I want to use a CMSIS-DSP FIR function in my code and get a compile error:compiling phase_det.c... ../Drivers/CMSIS/Include/core_cm4.h(81): error: #35: #error directive: "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)" #error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)" ..\Src\phase_det.c: 0 warnings, 1 errorIn Keil I used the 'Manage Runtime Environment ' to add CMSIS-DSP Library. In my source code file I haven't yet added the FIR, but I did add the include "arm_math.h".What does the above error mean? The STM32G431 does have an FPU as far as I know (Ref Manual). Anyway, I want to use fixed point FIR.What steps do I need to take to properly install the CMSIS-DSP Library?

Hi everyone. I´d like to use a HC4067 mulitplexer to expand analog inputs on a bluepill. I´m using Arduino IDE to program the thing. But I can´t get reliable results. The values are jumping up and down or not reacting to input (potentiometer).I´m wondering if using a HC4067 is restricted to certian pins?? I´m trying to use:int s0 = PB4;int s1 = PB3;int s2 = PA15;int s3 = PA12 ;SIG = PA4;I´m powering the HC4067 with 3.3 V and have grounded all inputs except input 1. I get fluctuating readings and POT on input 1 isn´t doing much, although I should see 0-4096.Any help appreciated. Keep in mind ... newbie here. Or father with just occasional spare time trying to build an RC transmiiter for his son.Before you ask: I use these pins because there are already other things going on on the board...NRF24 transmitter, Oled, etc.This code is just a test setup.//Mux control pins int s0 = PB4; int s1 = PB3; int s2 = PA15; int s3 = PA12 ;   //Mux in "SIG" pin int SIG_pin = PA4;     void

I'm developing a very small STM32L5 based USB-dongle and do not have enough space on the PCB to add an external EEPROM. So I came to the EEPROM emulation implementation provided by ST called X-CUBE-EEPROM.The example project for the STM32L5 seems to work fine, but I found that the EEPROM emulation implementation erases all empty EEPROM flash pages each time the microcontroller is power cycled. If erasing an already erased page counts as a new erase cycle, this behavior will wear out the internal flash without needs.

Hi guys,I started a project on keil µVision5.34 and a NUCLEO-H723ZG board. I would like to implement TCP-IP connection with a computer. After receiving an ARP request from the computer, the microcontroller enters in hardfault_handler. So it doesn't send its MAC address, and the TCP handshake can't be executed.Here I give you the description of my project :1.     In µVision RTE selection :CMSIS -> CORE EnabledCMSIS -> RTOS2 (API) -> Keil RTX5 Enabled, SourceCMSIS Driver -> Ethernet MAC (API) -> Ethernet MAC enabledCMSIS Driver -> Ethernet PHY (API) -> LAN8742A enabledCompiler -> Event Recorder enabledCompiler -> I/O -> STDOUT enabled, EVRDevice -> Startup enabledDevice -> STM32Cube Framework (API) -> STM32CubeMX enabledDevice -> STM32Cube HAL -> common enabledDevice -> STM32Cube HAL -> Cortex enabledDevice -> STM32Cube HAL -> DMA enabledDevice -> STM32Cube HAL -> ETH enabledDevice -> STM32Cube HAL

I need to store a two-dimension array (uint16_t array[100][15]) in flash for power loss reservation, But since my application is big enough and my internal flash is already running out (85%), It seems to be applicable to store my array in external nor flash (which I have in my custom board).So is there a reliable way to store my two-dimension array in the end pages of my nor flash memory for reserving?

When I refactor a global variable or function from its definition in a source file, all instances are replaced except the declarations in the header files.Attempting to refactor from the header file achieves nothing. The new name is immediately replaced with the original name.This is not ideal.Does anyone know why this might be happening? A bug, or a project configuration error?Cheers.

HiI'm using IAR EW for ARM.I would like to get a simple working project that is made for the STM32F767ZI processor, preferably running on a Nucleo-144 board.The example should only make the initialisation of the processor. I'm making a Bootloader so I don't think I need much more. I'm just worried with putting the Processor clock working.I'll be using FreeRTOS IP stack but for now I only need the processor starting.In there any Wizard for IAR that creates a simple example project running on the Nucleo-144?thanks

Hello everyone,I'm trying to implement EEPROM emulation in my custom design comprising of STM32F070C6T6 MCU. There is a small drawback in the circuit that I don't have Debugging available. Hence, I was using USB_CDC_Transmit for debugging. I was able to successfully initialize FlashUnblock and EEPROM functions provided in the "en.stm32f0_eeprom_emulation" files. However, I am now not able to write to or read from EEPROM. Does anyone know what might be the issues? What are the steps that I maybe missing. I am using the same structure as provided in the repository mentioned above. Please let me know if any files are needed to understand the scenario in more detail. Thanks
