Hello,I have programmed one of the advanced timers in up/down mode and I have used one of the compare units to generate a PWM signal.I would also like to generate an interrupt on compare events, but only on the falling edges.Is it possible to specify the edge directon when enabling the compare event interrupt?Or I have to distingush the edge direction only after the interrupt has been triggered on compare event, by checking the counter direction?Thank you,Carlo

hello.I was interested in stm32wb5MM, so I purchased the stm32wb5MM-dk board.The demo that ran when I powered on this board was very interesting as I was planning a similar project.I searched for STM32CubeWB to see the code, but the Demontrations folder was empty.How can I get the Demontrations code of stm32wb5MM-dk?

Hey,in the past we used a STM32F4 and in the new Gen I will use the a STM32U5 and there is my questen about the cryptographic firmware in the past we could use the libSTM32CryptographicV3.0.0_CM4_GCC.a but now is there also a Lib for the stm32u5? 

Hello, I'm using the nucleo-h743zi2 board.When obtaining the value of TIM2->CNT (or TIM5->CNT) through the combined channels of TIM2 or TIM5 on this board, without any special settings, I can perceive the encoder rotating in reverse as a negative value as it passes through 0. (For example, with a Counter Period set to 1000, rotating in the negative direction would result in 0, -1, -2, -3, etc.)However, when obtaining encoder values from other General Purpose Timers, it doesn't result in negative values but instead jumps to the maximum positive value. (For example, with a Counter Period set to 1000, rotating in the negative direction would result in 0, 1000, 999, 998, etc.)Is it possible to obtain negative values in this situation through settings?The difference I found between these two timers is that the counter resolution is 32-bit, whereas in other General Purpose Timers, it's 16-bit. Thank you in advance for any advice you can provide.

Hi,I use CubeMonitor V1.8.0 with my STM32G474QET device. Unfortunately the chart inside the dashboard is very small so I can`t work with it. Is there any possibility to set the size of the graph? The only thing I found is the duration in seconds, but that only changes the resolution but not the chart size itself. Thanks for any recomendations.Benedikt

Hi, All    my file system is working with the eval board of STM32U575I-EV.       However, run the same software with NUCLEO-U575ZI-Q, file system doesn't work.    I found that SDIO DETECT is changed to PD5 NUCLEO-U575ZI-Q which was  PF3 on STM32U575I-EV.    How can I change the SD card pin definiton in IOC? Thanks in advance. Best RegardsVictor

Hi,I'm working with a STM32F439ZI and want to use the PWM outputs of timer3 & timer4. I want to set a frequency of 50Hz (m_dat.fI) as an example. If I calculate it with the formula below, it results in a frequency of 100Hz instead and I'm not sure why, can someone help out?PSC is set to 27 for both timers. and PCLK1 is at 42MHzPCLK1Freq = HAL_RCC_GetPCLK1Freq(); TIM3->ARR = (uint32_t)(((double)PCLK1Freq / (double)m_dat.fI) / ((double)TIM3->PSC + 1)) - 1; TIM4->ARR = (uint32_t)(((double)PCLK1Freq / (double)m_dat.fI) / ((double)TIM4->PSC + 1)) - 1;

I can not connect my STM32H735G board via ST-Link anymore. "no stm32 target found". I tried "connect under reset" (ST Link Utility and ST programmer) as well as connecting boot0 to VDD. Any idea how to erase the flash and start over? Cheers Stefan

We are interfacing the USB 2.0 , on nucleo-L496ZG OTG_FS_IRQHandler routine is executing but incase of our own Hardware having LQFP64 pin package download the same code but OTG_FS_IRQHandler is not generating,may i know what is exact the issue?

Hi i have this code: char string[6]="Hello";char string1[6]="World"; touchgfx::Unicode::UnicodeChar dst[6];touchgfx::Unicode::UnicodeChar dst1[6];touchgfx::Unicode::UnicodeChar txtAreaBuffer1[100]; Unicode::strncpy(dst, string, 6);Unicode::strncpy(dst1, string1, 6); Unicode::snprintf(txtAreaBuffer1, 100, "%s", dst, dst1); Unicode::strncpy(txtAreaBuffer, txtAreaBuffer1, 100);txtArea.invalidate(); Why i have output only Hello instead HelloWorld? 

The description of the ThreadX Application Queue Message Size in CubeIDE/CubeMX is vague.The queue size is specified in "words". The C language doesn't define how large a word is, it's not even processor implementation specific (I even read that Microsoft specifies a word to be 16-bits on their 64-bit processors for backwards compatibility). ThreadX refers to a 32-bit word in their user manual, even though ThreadX runs on x86.Could the queue message size description (behind the (i) button) be augmented to mention 32-bit?(apologies, I should have posted this in the CubeIDE or CubeMX section)Thanks,Andrei

Hi - I'm using HAL_GetTick(), and then subtracting one value from another to determine a GPIO input pulse width.What happens if I happen to to call HAL_GetTick() around the point where the SysTick timer rolls over through zero.Do I need to watch out for this situation generally?Regards, John.

Hi,I have an UDP Server on a STM32H743ZI. It works very good only if the ethernet cable is already connected when I power on the board.However, if I connect the cable after powering on the board, UDP Server does not receive any message.FreeRTOS is used on my project and I have added LWIP_NETIF_LINK_CALLBACK 1 to lwipopts.h but I never go in callback function even if I connect/disconnect the ehernet cable.Where's the problem?what should I add to detect the cable connection?Thanks a lot!Kind regards.

Hello, I am using a nucleoH743ZI2 and STM32CubeIDE v1.13.2 on windows10I configured the USART 3 in order to receive some telecommands from my laptop (windows 10) using a software (HTerm v0.8.9)The telecommands are written in binary, 52 bytes, but the first 8 bytes are ASCII so I can read it directly, for example the keyword "C0FFEE5\0"I intialize my callback with DMA:   char UART3_rxBuffer[UART_DMAsize]={0}; HAL_UART_Receive_DMA (&huart3, &(UART3_rxBuffer[0]), (uint16_t) UART_DMAsize); And in a while(true) loop and I am reading every 3 seconds what is inside my buffer which receives TC by UART:     char configReceived[sizeof(TypeReadConfig)]; memcpy(configReceived, &(UART3_rxBuffer[0]),sizeof(TypeReadConfig)); printf("##++ ConfigReceived %d\r\n",sizeof(TypeReadConfig)); for(indice=0;indice<sizeof(TypeReadConfig);indice++){ printf("%c",configReceived[indice]); } printf("\r\n##++ End ConfigReceived\r\n");  &nbs

Can NanoEdge AI only generate.a static library? If so, how do I use it in keil? This is because keil does not use GCC but ARMCC.

Hello Community!Now a days i started Working on STM32H747 Discovery board. im trying to configure Ethertnet on Cortex-M7 core.i enabaled ETH in connectivity with RMII on M7 core. Selected FreeRTOS with CMSIS V2 and enabled the DCache. now when im trying to enable LWIP for M7 Core Enable check box is not getting activated.Problem 1: why LWIP Enabled box is not getting Activated for Cortex-M7 only?M7 lwip selectwhen im selecting M4 core in LWIP then n only its getting enabled. Problem 2: Why in the RTOS Dependency WITH_RTOS(USE FREERTOS) option is disabled?  M7 M4 LwipNote: Here i have already selected PHY Device In the Platform Setting after taking the Screen Shot.these issues is not coming in CubeMx 6.2.1 version.

My problems with Portrait orientation don't end.I have a very large project where changing the architecture and function calls costs much more than changing a single function.My problem is how?The function is readBMP24File.In my project it is loaded from several places and many different screens.In the original project it works very well, many images are called or even of different sizes from an MMC with fatfs.Has anyone solved the problem of changing orientation without having to change the position and orientation of the images?I'm starting to have serious doubts that the touchgfx gui really helps in the work I do.If anyone can help me in solving the problem with a new or different algorithm I would be grateful.

HelloI am using board NUCLEO-G071RBI wrote for it a code, and all worked well.Now I want to rewrite a new project for the same board, but elementary functions such as PWM output doesn't work. If I run again the old project all works OK again.Someone have any idea why this occurs?

The maximum sampling rate of STM32H743 ADC1 and ADC2 is 3.6MSPS. According to the aroma sampling principle, the maximum sine wave frequency that can be collected is 1.8MHz. I don't know if I understand it this way, right? I want to collect higher-frequency sine waves. Is there any way to use the built-in ADC? Can reducing the number of bits improve the sampling rate and collect higher-frequency sine waves?

Hello , Can you help me for the microntroleur reference 1) Why don't you recommend this product for new designs ?2) Do you have an idea of the number of years before the end of its life ?3) NRND information available in an PCN ? Thank you in advance

Respected Sir/Ma'am,                                   I'm designing 2KW SMPS from reference schematics design of "STEVAL-ISA172V2: 2 KW fully digital AC-DC power supply (D-SMPS) evaluation board". I've not faced any obstacle in designing schematics of the circuit with help of reference design. But in PCB design, I'm facing so much problem in Altium Design Professional Software.  I'll be grateful to you if you'll share the CAD/CAE symbol, Gerber file, PCB layout, Assembly drawing of "STEVAL-ISA172V2" with me  so that I can complete this design for physical board implementation. It will be very helpful for me to complete my project. I'm waiting for your reply.     Thanks & Regards,
