Hello,I want to use the LIS3MDL for a project. I am using a microcontroller with I2C lines at 3V3. In the datasheet there is mentioned that the typical voltage for VDDIO is 1V8 but with a range up to VDD +0.1 V. I will power the device (VDD) with 3V3. If I also use 3V3 for the VDDIO will the sensor communicate at 3V3 or 1V8. Thank you in advance

Hi everyone, I want to use other LCD-TFT screen with the STM32MP15X-EVAL board but there is something strange with this connector. There are two duplicated pins, R5 and R7 , but looking for on the board documentation, I can't find anything related with this. What is these pins function?Thanks in advice.

In my case I configured my counter as center aligned mode and my PWM mode as PWM mode 1.Finally I used the CCR(compare capture register) but i don't have no idea how this CCR work that means it sends a PWM signal every period of time or point by point.Thank you for your answer.

I have designed a custom developer board based on STM32WB55CGU6. I have both JTAG and SWD pins on the board. None of them works when I try to connect the board to the STLINK v3MINIE. Except any hardware issues, what else do you suggest for the very first-time flash for a new MCU.

I am using X-NUCLEO NFC08A1 dev board & NUCLEO-L476RG base board with STM32 IDE. I want to detect NFC card on eval board but currently the card is not getting detected. can you please help to solve this issue.not able to receive data on serial port also.

Hi,I have just installed STM32CubeIDE Version: 1.12.1 Build: 16088_20230420_1057 (UTC) onto my Kubuntu 22.04.2 LTS (fully updated) system. The install process ended stating that the IDE had been installed correctly.I then wanted to install the package STM32Cube_FW_F4_V1.27.0. So, following the step given by community member RJepp.1 on https://community.st.com/s/question/0D53W00001vE2MNSA0/how-do-i-install-stm32cube-mcu-package-for-stm32f4-series-1271-without-an-internet-connection, I also went to (IDE) Help->Manage Embedded Software Packages. However, in my case, nothing appeared on screen. All that happened was that the Help drop down menu disappeared.I should state that I did this while the IDE was displaying the Information Center<tab>/STM32CubeIDE Home page/screen.In the response noted above it is stated that "1. rename the main pack from "en.stm32cubef4_v1-27-0.zip" to "stm32cube_fw_f4_v1270.zip". I did this.The response noted above also stated that "2. Copy the zip file

Hello,I am looking at the smartcard example application - https://github.com/STMicroelectronics/STM32CubeG4/tree/master/Projects/STM32G474E-EVAL/Examples/SMARTCARD/SMARTCARD_T0_MFXIn the project .ioc file, I see that the Baud Rate is set to 10752 Bits/s, and the smartcard clock frequency is 3.863636 MHz.How was that baud rate calculated/determined, considering the above clock frequency?Thank you,D.

Does ST have list of STM32 MCU's with 10/100 Ethernet MII/RMII module? Also does ST have an MCU's with 10/100 Ethernet MII/RMII module in 64 pin package.I know for STM32F207xx series 100 pin package.

Hi,My application will use intensively use Virtual Com Port to exchange datas from my board to the PC. I would like to make sure that debugging through STLink is still possible as i will be exchanging datas. Does St Link use the same USB port for debug and application ?Thanks

I have successfully implemented a ZigBee coordinator/router with an on/off-server-cluster based on a STM32WB5MMG module.My application is able to form a network and automatically allows certain off-the-shelf ZigBee On/Off-Clients to join the network and bind to the cluster within my device. Persistency is working well, too.As long as my coordinator is fabric new it starts forming the network and allows other devices to join for a certain periode of time.But when there is valid persistence data no additional devices can join, because the network forming process is skipped (I followed the "Zigbee_OnOff_Coord_NVM" example from STM32Cube_FW_WB_V1.16.0).This raises two questions:1) How can I allow more devices to join the network? Wich API functions must I call for that?2) How can I detected that the joining-window has closed on my coordinator?Thank you very much for any hints or help Thomas

Hi all,I imagine it is to simulate that I'm looking from the top thru the package. I can see a quick repaint if I minimize cubeIDE and maximize it. I rather it didn't look so dark. I wasn't born with good eye sight and the darkness makes it hard to read the labels. Is there a way to get rid of the dark overlay? Thanks

We have a battery driven system based on STM32G031K8 and a S2-LP for RF running from a CR2032.I use the shutdown mode to keep power as low as possible. System is done by a reed contact connected to a wake up pin.We want to find out, whether the battery was entered, or the system reset was caused by exiting the shutdown mode.Further on, we use the standby mode and we want to know when the reset occurs, whether it was caused by exiting the shutdown mode or by exiting the standby mode.As both modes do a reset on exiting, I see no difference at the moment.Any ideas?Furthermore, when the battery is getting low, the processor does some resets, when the battery voltage drops below 1.7V and after some time, the battery recovers a little bit.Any ideas how to find out the difference betweeen that. Hence the battery voltage is not a good indicator, I already tried that.

Hi,I am using STM32F407 discoveryboard and I am trying to set the RCC configuration such as the clock frequency is 168 MHz.

Hello,I am making SPI DAC update function, and I could not get PG11 to output SPI1 clock. While if I switch to PB3 pin, all is perfect. (this is alternate pin for SPI1)If I toggle PG11 as GPIO, I get waveform so where is no short or something similar. Errata is also mute about this....LL_AHB4_GRP1_EnableClock(LL_AHB4_GRP1_PERIPH_GPIOG);   LL_GPIO_SetPinMode(GPIOG, LL_GPIO_PIN_11, LL_GPIO_MODE_ALTERNATE); LL_GPIO_SetAFPin_0_7(GPIOG, LL_GPIO_PIN_11, LL_GPIO_AF_5); LL_GPIO_SetPinSpeed(GPIOG, LL_GPIO_PIN_11, LL_GPIO_SPEED_FREQ_HIGH); LL_GPIO_SetPinPull(GPIOG, LL_GPIO_PIN_11, LL_GPIO_PULL_DOWN); LL_GPIO_SetPinOutputType(GPIOG,LL_GPIO_PIN_11,LL_GPIO_OUTPUT_PUSHPULL);This is don't work. I get low level all the time... But if I switch to PB3, all is great:LL_AHB4_GRP1_EnableClock(LL_AHB4_GRP1_PERIPH_GPIOB);   LL_GPIO_SetPinMode(GPIOB, LL_GPIO_PIN_3, LL_GPIO_MODE_ALTERNATE); LL_GPIO_SetAFPin_0_7(GPIOB, LL_GPIO_PIN_3, LL_GPIO_AF_5); LL_GPIO_SetPinSpeed(GPIOB, LL_GPIO_PIN_3, LL_GPIO_SPE

Hi all,I followed the tutorial "STM32CubeIDE basics - 04 EXTI HAL lab" video. I put the code in the CM4 core in my dual core NUCLEO-H745. I had an LED blinking in each core and that worked. I just added the interrupt stuff according to the tutorial video for the user button but it only works if I use debug and step thru the code. It doesn't work if I run the code. Only the interrupt stuff doesn't work. the LEDs blink just fine ... from both cores when run. What am I doing wrong?Thanks

Hello�?Recently, I was planning to use NUCLEO-L432 to create a smartwatch, but I encountered a fatal problem: running a program using external FLASH can cause the program to freeze.​Because I wanted to use LVGL as a graphical interactive interface, the 256K FLASH of L432KCU6 was not enough. Therefore, I used only burning bootloader on the chip and running the program saved in W25Q128 through QSPI. Due to limited funds, I have adopted the FLASH module, which has led to many strange problems (possibly due to non PCB wiring).​When I set the main frequency to 80MHZ (maximum), the program can only run for 16 minutes and will freeze; It can run for 40 minutes at 70MHZ; It can run for 60 minutes at 60 MHz, and the time of each stuck is the same. And since I divided the project into bootloader and app, I don't know how to debug my app program, so I don't know exactly where it got stuck.​I have no idea about this issue at the moment. May I ask if there is anyone who can provide some suggestions
