1 . what does means System Clock in MCU?does it mean electronic device in a MCU that issues a steady high-frequency signal that synchronizes all the internal components?​I want the exact meaning of System clock.2 . what is To Power(MHz) SYSCLK ​in Clock Configuration of STM32CubeMX connected to To Power(MHZ)What is To Power ?please reply to question. Thank you ***Moderation Edit: please do not post your email address on this website***

I'm running PC-Lint as an external tool with the results going an output console. I'd like to be able to double click on a PC-Lint error message in the console and have the appropriate source file / line displayed as per compiler errors. I have PC-Lint error messages formatted the same as complier errors but the IDE ignores double clicks on these messages.Is there any way to configure CubeIDE to get the desired behaviour ?

I can enable git in Atollic TrueStudio by setting Customize Perspective.

I use a ST-LINK/V2 and have tried to connect using ST-link utility program. This did not work so I assumed something was wrong with the hardware. But now I have tested to connect using STM32CubeProgrammer instead (I use the same ST-LINK/V2), and then everything works as expected. Is the ST-link utility program not supporting STM32G4 MCUs?

Hi,Looking at the reference manual, en.DM00327659.pdf, page 3929 it seems the simple way of debugging previous M4 processors using printf() redirect to the ITM and then using the SWO pin/STLINK interface could be used on the MP1 M4 core as well.But there isn't simple mention of the ITM functions in the STM32Cube_FW_MP1_V1.0.0 release, and there is not even a single declaration of the ITM HW in the stm32mp157cxx_cm4.h file(not even the 0xE0000000 base address).Can you provide some code example please, it will be much better starting point than the vague description of the ITM operation in the reference manual. Thank you!Edit: ST-Link utility connected to the STM32MP157C-DK2 dev board seems not able to connect (loaded with latest V2.J34.M25 firmware) to the MP1. It does reset it though, so printf in the SWO viewer is out of the question. Maybe there is a way to redirect ITM to the M4 core ?Second, seems the M4 ITM hw is loosely based on the STM32F469/479 ITM core(at least register addres

Hello,I have started working on the STTS22H and noticed that, at least for my part, the datasheet I2C addressing directive seems to be inverted. Aside from the fact that the datasheet and the evaluation kit have different addressing directives, the evaluation kit seems to have the ADDR pin connected to VDD which would mean the 7-bit address is 0111 000. However, when testing out the sensor it would only respond when using the 7-bit address 0111 111, which is the configuration for when the ADDR pin is connected to ground as pointed out in the snapshot from the datasheet below.Could that mean that there is an issue with the datasheet or could that be an issue with the kit I have got?On another unrelated topic, what is the default value of if_add_inc in the CTRL register on boot?Thanks.

Hi,I finished the board bring up introduction: Board Bring Up Introduction | TouchGFX Documentation without any troubles. I can also write and read to the external flash through DMA2D by using the following function:LL_FillBuffer(LTDC_LAYER_1, (uint32_t *)(hltdc.LayerCfg[LTDC_LAYER_1].FBStartAdress), 1024, 600, 0, (uint32_t) 0xFF008000);static void LL_FillBuffer(uint32_t LayerIndex, void *pDst, uint32_t xSize, uint32_t ySize, uint32_t OffLine, uint32_t ColorIndex) { /* Register to memory mode with RGB8888 as color Mode */ hdma2d.Init.Mode = DMA2D_R2M; hdma2d.Init.ColorMode = DMA2D_OUTPUT_RGB888; hdma2d.Init.OutputOffset = OffLine;   hdma2d.Instance = DMA2D;   /* DMA2D Initialization */ if(HAL_DMA2D_Init(&hdma2d) == HAL_OK) { if(HAL_DMA2D_ConfigLayer(&hdma2d, LayerIndex) == HAL_OK) { if (HAL_DMA2D_Start(&hdma2d, ColorIndex, (uint32_t)pDst, xSize, ySize) == HAL_OK) { /* Polling For DMA transfer */ HAL_DMA2D_PollForTransfer(&hdma2d, 10);

I think I got the setup for the Real-Time-Clock (RTC), but how do I verify it is working?Is there a way to output the timestamps or check through a file? I am using the STM32WB55 Nucleo Board, and currently using the STM32 IDE.

I'm using ST-Link_CLI.exe command line to programming our product in test jig, the previous tester is using Win7, it seems works reliable, but now update to Win10 and get problem with power up the tester.When powerup the tester, the PC can detect the ST-Link, but can't detect the STM32MCU, I must unplug the USB and plug in it again, then it can detect the STM32MCU, it will be very annoying to unplug and plug the USB for every unit. I update the ST-Link to latest firmware, it still the same.I use "STM32 ST-Link Utility" to check , the Win 7 PC works stable when power off/on, but Win 10 PC very often can't connect to my STM32MCU (40 % possibility).My Win 10 "STM32 ST-Link Utility" is the latest version: ST-Link Utility: V4.6.0.0 STLinkUSBDriver.dll V5.1.2.0 ST-LINK_CLI.exe V3.6.0.0I'm using "ST-LINK_CLI" and "STLinkUSBDriver.dll" for my tester coding, should I add something extra for Win10? There is "en.stsw-link009", should I add this to Win 10?RegardsSam

It's mean St-link Utility will disapear and will be unavailable on ST site? If so, how much time I have to start using CubeProgrammer?Thanks for any answears.

Hi!Just purchased a SensorTile.Box, and moving now to use it on Pro Mode.On the SensorTile.Box user manual, it is mentioned that the product includes an adapter board - however, the one that I purchased did not include one. Does anyone know how can I obtain this adapter board? Doesn't seem to be available at ST website...Many thanks in advance.Miguel

or if I must write my own code, how to do itThank you,

I try to create a project based on CAN bus but the CAN option is disable in CUBEMX ide.*Controller - stm32f042g6u8 *Cube mx ide version - V 4.24i want to know how to create a CAN BUS project using cubemx & without it,Examples are suggested for better understanding

Hi All,I please need your help as I have been stuck longer then I care to admit,I have a STM32G431 48-pin device which I am using TIM8 for input capture with DMA. I have an external input (PC6) for Ch1 input and am using a software trigger for Ch3.I have a couple problems, (1) The CCR1 is getting triggered but the corresponding DMA for DMA1_Channel1 is not being triggered and (2) I am using TIM8->EGR = TIM_EGR_CC3G to trigger a capture on CCR3 but CCR3 is not getting loaded.Is TIM8->EGR = TIM_EGR_CC3G the correct code to trigger a CCR3 capture?Attached is my main.c edited to reduce post length. I have a MX_DMA_Init() which enables the DMA1MUX clock and DMA1 clock as well as sets the IRQ priorities. DMA_Config configures the DMA parameters for TIM8 Ch1 and Ch3. Before entering the while() loop I enable the CCER and set the DIER register. TIM8->DIER |= (TIM_DIER_CC3DE | TIM_DIER_CC1DE) ; /* enable TIM8 capture / compare */ TIM8->CCER |= ( TIM_CCER_CC1E | TIM_CC

Hi,I'm struggling with the BSP LCD functions. The goal is to display an image which has transparent background. I'm working on STM32F429I-Discovery board, using BSP LCD drivers.Since the BSP_LCD_DrawBitmap() function seems to expect a real BMP file, which doesn't contain alpha channel information, I want to create my own function for drawing the picture.Currently I'm only displaying a text to verify that the LCD functions are working in general which seems to be fine.For the transparency check, I made a small test loop. Here, a vertical line is displayed pixel by pixel with black color and the alpha channel is incremented for each pixel:for(int y = 0; y < 256; y++) BSP_LCD_DrawPixel(10, y, y << 24);Now, what I expect is that the line will be transparent at the beginning and becoming opaque at the end. But it is drawn fully opaque. I don't know what I'm doing wrong.My main code (without the above mentioned loop):/* Initialize the LCD Layers */ BSP_LCD_LayerDefaultInit(0, LCD_F

Hello,is there any way to set the user descriptor string on the USB CDC device?In the HAL library, I found some functions related to descriptor strings, but their type is "get" and I did not find a corresponding "set" functions.

Currently I am using the STM32H753ZIT6 to do all the bare metals. Essentially what I am trying to do is just enable UART4 Tx to send some debug messages thats all. Everytime I try to enable the DMA1_Stream3 (UART4_Tx) it just gives me a TEIF3 error and doesnt enable the DMA_Stream3, where as the Rx works fine (It can get enabled).Whats going on here?MAIN:#include <stdint.h>   #include "EXIT_FACTORY.h" #include "CLOCK_FACTORY.h" #include "I2S_FACTORY.h" #include "UART_FACTORY.h"   static int I2S1_TxBUFF[4096]; static int I2S1_RxBUFF[4096];   static uint8_t UART4_RxBUFF[1]; static uint8_t UART4_TxBUFF[1];   int main (void) {   INIT_CLOCK(); INIT_I2S(I2S1_RxBUFF, I2S1_TxBUFF); INIT_UART(UART4_RxBUFF, UART4_TxBUFF); INIT_EXIT();       //TIMER     while(1) {         } }Code:// ENABLE DMA RCC->AHB1ENR &= ~(RCC_AHB1ENR_DMA1EN); RCC->AHB1ENR |= RCC_AHB1ENR_DMA1EN;   //Setup DMA DMAMUX1_Channel

I want to use ST25DV-I2C's Fast Transfer mode on iOS and Android.It seems that it can be done on Android, but is it possible on iOS?I would like sample code if possible.

I am having a hard time finding out the state of the UART pins while the chip is held in RESET. Are pins E2, D5, D4, and E1 held in a high-impedance state while the RESET pin H9 is pulled low? I suspect they are, but am trying to confirm through documentation.Thank you.

Hello, I am designing with a STM32L011 (16KB) and setting up with STMCubeIDE. I require I2C, LPTIM,DMA and A/D with a small amount of program space for my actual program. The HAL however uses up all the flash space. Just adding the MX_ADC_Init() function uses about 2KB and overflows my last 10% of flash.

I have a toggle button widget directly dragged from TouchGFX designer to the UI. I am unable to manually set the state of the toggle button to True/False using the ForceState (it just flashes between True/False every time I set the state ) Is there a way to i.e. setState() the toggle button and update it's corresponding image?Thanks...
