  Hi,i am working on STM32cubeIDE for STM32G071RB nucleo-64 dev board with windows 11.i have a ST-LINK/V2-1 programming and debugging tool is integrated into the Nucleo as shown below image.To power the board, I connect the STM32 Nucleo-64 board to my laptop with a USB Type-A to Micro-B cable through the USB connector (CN2). As a result, the PWR green LED (LD3) lights up and the COM LED (LD1) blinks.I checked the jumper position on the board, STLK (CN4) on [1-2], [3-4], PWR (JP2) on [1-2], IDD (JP3) ON.I installed stsw-link0009 USB driver for ST-Link/V2-1 to make this connection successful.But, still No ST-Link is visible in Device manager, image is attached below. kindly support me to fix this issue and looking forward for your response.ThanksBest RegardsSachin chhaleria

Hi, I want to get synchronized samples from 4 microphones connected via I2S2 and I2S3. First I set one as master and other as slave and just connect Clock and Word Select, but I have only 0 values on slave interface. Is it possible to do it this way? Or there is another better one? I am using STM32H533

Hi all.I'm working on a project where my MCU (STM32H755) communicate with a device via UART at 921600 Bauds.Here some details about the environment:The device sends constantly, each second, a log at 921600 Bauds. The MCU sends at same speed some commands to the device, the device will answer after that the command is executed and continue to sends out log. There isn't any synchronization mechanism for communication (no clock signal or CTS/RTS is used), plus, there isn't any difference or special character that will allow me to differentiate between command answer and log, so I must take everything I receive in a window of time and parse it at upper level (not relevant for this question), and, finally, to manage the communication I tried with FIFO enabled and disabled (but result seems to not change)What I do to manage the communication is the following:1a: Flush Read data register (but is this sufficient in case of FIFO enabled?)2a: Enable DMA via HAL_UART_RECEIVE_DMA API3a: Enabl

Hi all,I am using STM32G030F6P6 and trying to read ADC channel 11 and channel 16 using DMA.ADC works correctly in polling and interrupt mode.When I enable DMA, the ADC values in the buffer remain 0 all the time.DMA does not trigger at EOC, and DMA transfer never happens.I have been trying for 1 week, and I cannot understand what is wrong.What I have done:Configured ADC correctly (calibration, sequence, sampling time, etc.)Configured DMA correctly (channel, source/destination, size, circular mode)Enabled ADC DMA request (DMAEN)Enabled DMAMUX (for STM32G0 series)But still no data is transferred and buffer remains 0. #include "stm32g030xx.h" #include "gpio.h" volatile uint32_t adc_value[2] = {0},adc_buff = 0, adc_index = 0; void delay_ms(uint32_t ms) { SysTick->LOAD = 64000 - 1; // 64MHz ? 1ms SysTick->VAL = 0; SysTick->CTRL = SysTick_CTRL_CLKSOURCE_Msk | SysTick_CTRL_ENABLE_Msk; for(uint32_t i = 0; i < ms; i++) { while(!(SysTick->CTRL & SysTick_CTRL_COUN

Hi,I am working on custom board with STM32MP257. I am trying to enable i2c7 but it is RIFSC blocked.When I try to change the rif configuration for i2c7 the flashing process is interrupted and I cannot download the FW.Any help would be appreciated.Thanks.

HiI'd like to do a memory-to-memory transfer, where I take a 8x12 px rectangle and copy it into a framebuffer. My display is 256x64px and it uses a grayscale 4 bpp format. My framebuffer size is 8192 bytes, and the rectangle that I need to copy is 48 bytes big. I'm confused whether I should use L4 or L8 because L8 seems more straightforward for my byte ordered graphics.I set my screen byte width to 128, and I used L8. My output image looks garbage, as if the alignment was off (bad stride maybe). What is suspicious is that the garbage image is 4 lines tall, which could mean that the stride is calculated with 2 bytes instead of 1. Based on the RM0468 I think in no PFC mode it only uses the foreground and if I use L8 as hdma2d.LayerCfg[1].InputColorMode = DMA2D_INPUT_L8; (which btw. couldn't be set with CubeMX) it could increment the address correctly. In addition, if I'm copying a 256x64px image to the frame buffer, it is working properly. void write_framebuffer(

Hello Everyone, I’m having trouble understanding how to get the STSW-WMBUS-GUI (GUI for wireless M-Bus stack evaluation of ST Sub-1GHz devices) to work with the STEVAL-FKI868V2 mounted on a NUCLEO-L053R8? https://www.st.com/en/embedded-software/stsw-wmbus-gui.html Does anyone have or know the details to get this to work?Thank you. 

Im trying to drive 3.5 inch TFT LCD with STM32H743 using FMC. My setup is : ChipSelect: NE1 Memory Type: LCD Interface LCD Register Select: A18 Data: 8 Bits My timing settings are (FMC Clock: 10Mhz):  Address setup time in FMC clock: 3 Data setup time in FMC clock: 2 Bus Turn around time in FMC clock: 2 Here are the parts of code: #define FMC_BASE ((uint32_t)0x60000000) #define LCD_CMD (*((volatile uint32_t *)(FMC_BASE))) #define LCD_DATA (*((volatile uint32_t *)(FMC_BASE | (1 << 18)))) When I try to write a data, as shown in the attachment, my logic analyzer shows me multiple WR event occured and shows some weird signals on data line (D0-D3). I do not understand where I did wrong...

Attempting to blink an LED using output compare function of a timer, but I've not been able to get signal or toggling to happen on the pin.I'm using TIM5 channel 3, because I'm planning on using SPI1 eventually (I need to use a clock source separate from SPI1, which is on APB2) and the TIM5 associated alternate function GPIO on PA2 is in a convenient location.Meter on the pin indicates a floating pin signal (not going high or low), and LED visually indicates same (no dim light or other visual indication of rapid toggling).The pin itself is fine as normal GPIO: setting same pin as GPIO (not alternate function for TIM5), I'm able to blink "manually" via software. It seems to just be using that pin as TIM5 that causes problems.Here's the CubeMX setup:My understanding from the datasheet is that TIM5 is on APB1:APB1 timer clocks set to 10.5MHz:...so TIM_CLK/CKD/((PSC + 1)*(ARR + 1))= 10500000 / 4 / ((43749 + 1) * (59 + 1))= 1 Hz (should be blinking once per second)

I have worked with ST-LINK/2 on Windows 10 for several years. I must upgrade to Windows 11 because Windows 10 support ended a few months ago. Today, I tried to program the WIO E5 Mini microcontroller, but I found it's impossible because there's no driver for it on my computer.I found some information that I should install version 9 of that driver. I downloaded it from the original STM source and ran it, but nothing changed. Is till don't see this driver among my devices. Installation ended without any error. Is there anybody who can point out what I am missing?

Hi!I want my ESP32F411CE Blackpill to operate as an SPI slave device. The Master is not my creation, it is an already existing hardware, and my task is to emulate some Slave.Well, almost SPI. Here is what happening: Master sets CS line high, and reads 3 byte from the Slave on MISO line. Then it sets CS line low, and sends one byte on MOSI line. CLK frequency is 1MHz, SPI Mode2. I know it is not a proper SPI communication, so there is a transistor added that inverts the CS line. So the MCU doesn't see this in the image above, but the CS line inverted. It is a win-win, because it make the second short clock signal skipped, and that is exactly my intention.I don't care what Master sends, I only want to send that 3 bytes. This is all I want to do! For the first step I created a code, that sends the same 3 bytes, so I can see whan is happening on the oscilloscope / logic analyzer. These three bytes are: volatile uint8_t buttonsOutSPI[3] = { 0xAA, 0xAA, 0xAA };ORvolatile uint8

Hi Everybody!At this time I would like to use two EVAL6498L board for a DC brushed motor, (H-bridge setup).Selected mosfet is: IRFZ34NPBF.Selected PWM frequency: 20kHz width the STM32G431 MCU.The PWM signals are generated on the GPIOs, and I’ve verified that they reach the driver’s HIN and LIN pins. The low-side MOSFETs switch correctly, but the high-side MOSFETs won’t turn on. The bootstrap capacitors are charged to about 12 V (measured directly across the capacitor leads). The control table is the following:TIM1 chDriver InputForwardRevers1A LINForced HighForced Low2A HINForced LowPWM3B LINForced LowForced High4B HINPWMForced Lowhttps://www.st.com/resource/en/data_brief/eval6498l.pdfAdded R4 and R7 with 10 Ω resistors.What am I doing wrong? 

Hi, I would like to develop an application using ADC + TIMER + DMA. My base code doesn’t work, and I don’t understand why. To debug, I introduce the variable "toto". This value of this variable doesn't change. I use STM32CubeIDEv1.19.Best regardsThomas- H

When I open the official example using the example selector, CubeMX cannot display the graphical configuration of that example. I would like to know if it is possible to display the graphical configuration of the example in CubeMX. Thank you very much, because that would make learning much easier.

Originally a comment on the "Using CAN (bxCAN) in Normal mode with STM32 microcontrollers (Part 2)" Knowledge Base article.Moved to the forum for better visibility & discussion.Hi,I just using STM32CubeIDE for 2 or 3 days. I am doing a test with a Nucleo-L476RG and CAN bus. With you help, your sample, I make my board talking with other board of mine.Just a question, maybe a *** one, where can I gather informations about CAN_TxHeaderTypeDef, uint32_t RTR  or uint32_t IDE... and so mutch other symbols? Is there a documentation about?Best Regards,Maurice.

I generated project with CubeIDE for Nucleo F411RE board with defaults.Now I want to create my own function void LED_blink(int blink_num);So, I created ledfunc.h and ledfunc.c files.This is my ledfunc.h file: #ifndef INC_LEDFUNC_H_ #define INC_LEDFUNC_H_ void LED_blink(int led_number_blink); #endif /* INC_LEDFUNC_H_ */and this if my ledfunc.c file: void LED_blink(int led_number_blink) { for (int i = 0; i < led_number_blink; i++) { HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_SET); HAL_Delay(100); HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_RESET); HAL_Delay(100); } }and I want to use LED_blink(2) function in main.c( which was generated by CubeIDE )When I try to build code, I'm getting errors LD2_GPIO_Port undefinedYes, those defined in main.hWhere (in which file ) I need to include #include "main.h" ?I need proper way where to add #includeEdited to apply source code formatting - please see How to insert source code for future reference.

We use a an STM32L4R9-DISCO board to start SW development on a project.We run own OS on the board and integrating the HAL/BSP modules for the board (e.g. STM32CubeL4\Drivers\BSP\STM32L4R9I-Discovery\stm32l4r9i_discovery_io) is not feasible for us.I have basic I2C running (ack from the MFX) but no reaction to any commands, using the registers defined in mfxstm32l152.hI therefore need basic documentation of the MFX_V3 I2C communication for setting up port directions, getting and setting ports.rgds Tage

Hello everybody, I am currently trying to trigger a DMA request with TIM12. I have configured the timer in PWM Input Mode on CH1. While for every other timer there is available a DMA request, there is nothing for TIM12 except the one bellow(in RF0399): Is there any trick to come around from it? I found some older discussion but i didn't have any luck:How to trigger SPI DMA transfer using TIM12 TRGO on STM32H7  Timer events as DMA triggers - Improving the current situation in CubeMX/HAL  Thanks in advance for your time!

Hi!I have the following code:uint32_t currentTicks; do { currentTicks = handle->controlData.ticks; // controlData.ticks is volatile // copy a lot of data from handle->controlData ... } while(currentTicks != handle->controlData.ticks);handle->controlData.ticks (and the other data fields) are regularly updated, triggered by an interrupt, which could happen during copying of this data. The idea is that if the while check is false, just copy all the data again, since during the previous copying of said data new data must have arrived and the copied data would therefore be inconsistent.We are running on an STM32H7 and the data is in DTCMRAMFor this to work, is a Memory barrier instruction required or could there be any other pitfalls?
