Hi, i have build up  Normal mode program For CAN on  board (stm32f103c8t6) setup. It is showing that data is transmitting but when I tested on board there no DataCan you tell me what is the problem??

Hi,Why there are no QFN packages for STM32U59 series? Will it be added in the future?Thanks.

In file stm32c0xx_hal_conf_template.h there are duplicated lines at 239 row.#ifdef HAL_UART_MODULE_ENABLED#include "stm32c0xx_hal_uart.h"#endif /* HAL_UART_MODULE_ENABLED */ if you are using Cube MX you can't compile.  

Hi everyone I'm trying to use external debugger with my stm32 disc1 board. The problem is if i only connect the stlink and my board i can't debug it, but if I power the board with another usb port i can access it.So my question is why do i have to power the board with external source and how can i power it only using stlink debugger.

I am using STM32H7 and using the M4 core to output GPIO to control peripherals.I share data between the two cores using the share memory protocol.On the M4 core, I have turned off all interrupts and only control GPIO, but when measured, there is still a delay of a few milliseconds => the output is incorrect in timing. And notably, this only happens when I enable DMA from SPI on the M7 core.Can you tell me the reason and provide a solution?

Hi, I want to make an application in which 4 different signals to be produced with different frequencies. I am using timer output compare mode. My board is STM32F407VG-DISC1, so I use on board LEDs as TIM4_Channel1, TIM4_Channel2, TIM4_Channel3 and TIM4_Channel4.I use HAL_TIM_OC_Start_IT API in order to change the value of CCR so that whenever interrupt occurs, the value in register is updated which enables me to control the generated frequency.But this does not work.First of all, 4 LEDs blink at the same rate, no matter what values I provide in the interrupt callback function via __HAL_TIM_SET_COMPARE function. I can control the frequency of the signal generated via the counter clock, under configuration tab of the TIM4 mode and configuration on STM32 Cube IDE.The frequency increases when I lower the prescaler. I have got few questions.Why cant I generate signals with different frequencies ?I suspect that the interrupt callback is never called, is that the case ?I

Hi,I would like to check if STM AEK-POW-BMS63EN board can be used as a first board in the daisy chain with the setup where we have external MCU (for example STMF103RB) and AEK-COM-ISOSPI1?In the datasheet you describe difference between 'Master' and 'Slave' in the following way:and all your AEK-POW-BMS63EN comes with SPEIN pin pull-down via R20: Can you please clarify if the usage of AEK-POW-BMS63EN in the single BMS setup with external MCU is even possible?BR,MaraLo

Hi, I want to conect an external MCU to the STM32F746 DISCO using UART but I dont know how to use another UART other than the one used for communication with the PC.

Hi,I am looking for a delay function for  1 us, HAL_Delay provides 1 ms, is there one in HAL or somewhere else?RegardsChao

Hi, I am trying to use STM32F103C8T6 standby mode and wake it up with wake up feature of RTC, but in CubeMX I don't see that this MCU would have wake up feature under RTC settings. How do I wake up this MCU from standby with RTC and wake up pin?  

"Hi,We are building hardware with the SPC58EG80E5 MCU. For debugging purposes, we plan to use the UDESTK-EVAL kit. However, on the product page, it states that it is "not recommended for new designs." What alternative options can we consider?"

Hi, I am using L9663, can you send me a driver code? Or a schematic diagram of the wiring

I noticed that STM32U5G9 MCUs are already available for purchase. That is, STM32U5G9J-DK1, STM32U5G9J-DK2 and several bare bone chips.1) In CubeMX those products are still marked as 'coming soon' but this is the least of the problems.2) The most simple CubeMX-generated project does not build. stm32u5xx.h file is missing, stm32u5g9xx.h file is nowhere to be found, Drivers\CMSIS\Device\ST\STM32U5xx\Include folder is empty. Am I missing something? Was STM32U5G9 CubeMX support ever tested? I used the latest HAL package 1.4, I believe STM32U5G9 support was added in version 1.3.3) Where do I find the detailed GPU2D documentation describing the details of the new vector graphics functionality? I was unable to find any details on GPU2D, even the one available in STM32U5A9 (no vector graphics) released a year ago. RM0456 section 45 Neo-Chrom graphic processor (GPU2D) counts only 3 (three) pages and looks more like a content placeholder.

Hello everyone,I'm working on a project involving STM32's FMC specifically focusing on expanding memory capabilities. Given that each SDRAM bank (Bank 1 and Bank 2) can address up to 256 Mbit, I'm curious about the feasibility of integrating a single SDRAM chip with a larger capacity, specifically a 512Mbit chip with 13 address lines, such as the one detailed here: https://www.issi.com/WW/pdf/42-45R-S-32160F.pdfIs there a method or configuration within the STM32 FMC that would allow me to effectively use all of the 512Mbit SDRAM's capacity? or I have to use two 256Mbit SRAM with the individual clock and chip enable controls. Any insights or guidance on this would be greatly appreciated.Thank you in advance for your assistance. 

I have a Nucleo WL55JC1 and I'm trying to run the SubGHz_Phy_PingPong example from STM32CubeWL v1.3.0. I am using STM32CubeIde and if I try to build without any modification to the original project the compiler outputs that stm32wlxx_nucleo_radio.h, stm32wlxx_nucleo_errno.h and stm32wlxx_nucleo.h files are missing and aborts. If I add those files and corresponding .c files everything compiles, but I can't manage to get any output on the serial port. The readme.txt file says that when the system boots two leds on the board should blink, but I can't get neither that. I tried some some debugging and I didn't get anything useful.What have I done wrong? May I have skipped some configuration or tweaking?

Hello Everyone, good day, Recently I have implemented RTC to my TouchGFX project for my Riverdi RVT70HSSFWCA0 STM32 Embedded Display that uses a STM32H757XIH6 Microcontroller. I have managed to get the time and date to show on the display, all is working well. Except that the RTC is only running when the power for my display is on even though I placed a battery at the back of my display (which is connected to the VBAT pin of the stm32) The battery has 3 V coming out so its not a battery problem. I do not know why it is not running while the power is off, can anyone help me with this? Do I have to write any code for the display to be able to use the battery? Please provide kind support, thank you best regards. 

Hello,I am trying to connect b-cams-omv(ov5460) camera module into STM32F746G-DISCO board.However I can not find an official sample code examples.I downloaded FP-AI-VISION1_V3.1.0 SW package from ST web-page. When I unzipped it. it found in Drivers\BSP\Components\ov5640.c, but there is no a sample code example regarding STM32F746G-DISCO board.How can I get help?

I am wondering, if one only downloads MX, then how the software is built? Is the standard arm-eabi-none toolchain enough? Are in the standard toolchain all the needed include files and libs present? Or ST used its own version of the toolchain, libs, etc? 

How do I solve this error? "Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication"I use SWD. I made the cable for SWD communication. The cable is connecting ST-LINK V2 between board. Yesterday, well, was connected to STM32CubeProgrammer.But today it wasn't connected suddenly.....I did everything I could by exploring the STM32 community.Changed ST-LINK V2, the cable, reset mode, etc......I saw massage what "ST-LINK error (DEV_TARGET_CMD_ERR)" in hardware rest mode.But I don't solve this error.Please help me....

Hi, i was wondering if it is possible to make an exact copy of an existing STM32F405RGT6 and write to another. The use case for this is an open source motor controller (VESC). i have a fully functional board, and one that i have replaced the stm32 on due to it having an internal short. (Im not exactly sure what happened, the LDO was getting very hot and there was 5v on both Vin and Vout, removed LDO and Vin and Vout were shorted, removed stm32 and short went away. soldered in new LDO and STM32 and it now powers up). I can relfash it via SWD through VESC tool, which includes the firmware for some of the variations of hardware, using the functional board as the link between my computer and the new board by connecting the CLK,DIO and GND between the 2, but none are the right configuration. The company that sold these has been defunct for years, and i cannot find the firmware anywhere, so i was thinking if this was possible, this would be the easiest route. the alternative being reverse en

I am developing an application using TIM3 with Direct-mode capture compare to measure short pulse widths of 1 to 32 microsec. I am using a Nucleo H7A3ZI-Q board for development. The clock speed is 260 MHz. The Direct capture compare on Ch1 is set the pulse duration by triggering on both input pulse edges.My question is how much time jitter is there from when pulse arrives to the CC1 input till it is registered in CC1R register? I would guess one clock pulseis needed so the time-jitter would be one clock period. A timer resolution of one clock pulse is given in the specifications (Table 113). It is not clear to me if this also applies ot the capture compare input operation.This probably needs advice from somebody in STM who has inside knowledge on the timer circuit.Thanks in advance.

Hi,I'm having trouble getting PWM output on my STM32F303. I'm using CubeMX for pin config, then generating for Make for use with VSCode on Ubuntu. TIM1_CH3 has been configured for PWM output on PC2, and TIM1_CH2 on PC1. CH2 works as expected, while CH3 seems dead as a doorknob other than picking up some noise from CH2. Same config for the two channels (could they even be different?), and I'm calling the starter functions as follows, shortly after the CubeMX-generated init function:   HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_2);//MTR2 HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_3);//MTR2  Any reasons for this to be happening? I noticed quite a few people have a problem with TIM1_CH3, but they always seem to do the initialization themselves, which I figured MX would do for me.

Hi,I am using STM32CubeIDE to build project fro STM32H753 microcontroller.I am unaware why the STM32CubeIDE is updating the type of uint32_t to unsigned long.I assume for a 32 bit processor uint32_t should be typed to unsigned int.Where do I find declaration of __UINT32_TYPE__ ?/* Sample code to report issue */uint32_t my_id = "1234";sprintf( tmpstr, "Ser# %08X\r\n", my_id ); On compiling code I observe:../User_Code/File_Xxx.c:205:36: warning: format '%X' expects argument of type 'unsigned int', but argument 3 has type 'uint32_t' {aka 'long unsigned int'} [-Wformat=]205 | sprintf( tmpstr, "Ser# %08X\r\n", my_id );| ~~~^ ~~~~~~~~~~~~| | || | uint32_t {aka long unsigned int}| unsigned int| %08lXIs there a way I can instruct STM32CubeIDE to type case uint32_t to unsigned int.I also want to ensure that my change is not overwritten when I regenerate the code with help of IOC file. Regards,Rajeev 

Hello everyone,In the schematics en.MB1389-WL55JC-highband-E02_Schematic,there's a Pi filter following the RF switch before it links to the SMA connector for the antenna.Upon calculation, I found that the cutoff frequency of this low-pass pi filter is approximately 1800 MHz, which is significantly higher than the 870 MHz of LoraWAN. Could someone clarify the intention behind including this section in the schematics?Ultimately, I intend to integrate a chip antenna onto the PCB and eliminate the SMA connector.Should I retain these filters, or do I need to adjust the values of the pi filter components?Thank you!
