Hello thereAs per document UM2237, I am using command:STM32_Programmer_CLI.exe -c port=SWD index=1 mode=HOTPLUGto connect to the device. Successfully, device is connected.In case of reading a specified memory, one uses e.g. command:STM32_Programmer_CLI.exe -c port=SWD index=1 Fast mode=HOTPLUG -r32 0x20000000 0x00000002Which works as a charm. However... these command (directly taken from ST UM2237), issue a connection each time a read is issued.Of course I tried with only command:STM32_Programmer_CLI.exe -r32 0x20000000 0x00000002However the "Error: connection to target must be established first." pops up.Here bares the question. Is it possible to connect to target only once and then trigger some readings, without reconnecting each time?Thank you!

Hello,is the drivers to configure BLUENRG-2 and BLUENRG-2N are the same ?can i use the same driver from x-cube-ble2 to make an application with BLUENRG-2N ?Thank you.

I was searching for the security features of STM32F769I - DISCO and came to know that only STM32F77x has CRYP and HASH in the STM32F7xx series.Do STM32F769I - DISCO really have security features? If so, can you provide a relevant document regarding to the security features of STM32F769I - DISCO board?

The above designated code seems not to support STM32 CUBE IDE. It is based on the SW4STM32 and MDK-ARM platforms. Can anyone please direct me to the proper source? Or, is there a way to convert any of these to cube IDE? Thank you :folded_hands:​

Hi! I'm running TouchGFX 4.21.3 on a custom board with the following hardware.STM32L452RET6QSPI W25Q128JV for storageLCD 320x172 SPI ST7789v3Everything is working fine expect that image widgets that contain alpha values are now shown properly. I'm still trying to understand the settings that might help solve this problem, here is my setup in TouchGFX:The icons on the top left and right corners have some colours that are not totally white.The icons are png files saved in RGB 8bit mode for all channels.The icons for the battery that are drawn with just completely white pixels work just fine.Images are stored in the external flash and are fetched through QSPI DMA.The configuration for TouchGFX images is as followsHere is how it looks like on the actual hardware I've also tried different settings and modifying the defaults on the Image asset table without any luck.Can anyone explain what I'm I missing or what combination of settings should I use?Thanks,Martin

Hi, I have a STM32F407G-DISC1 board and I'd like to monitor some values (I/O pin states) using the CubeMonitor. However, when I try to configure the ACQ node no probe is found. I downloaded the latest version of the ST-Link driver and it does show up as a COM port.Any idea for a solution is welcomed!

I used the Linker options to set optimization earlier today. Now, I no longer seem to have that tab in Project>Properties. Using the latest version of the IDE (1.12.0). I'm sure it's something dumb I did, but can't figure out how to get it back.

Hi,How to configure the Compiler Optimization level in VScode for STM32? Is there a dialog box for that? As in STM32CubeIDE.

For a project using several powerStep01 drivers it would be very useful, if each powerStep01 could be identified by a unique ID or a serial number. In the interface description no such register is defined. Is there maybe a hidden register available which could be used?

I am testing LTE modem with a STM32H747 MCULTE modem is connectied with STM32H747 thru USART2.I want to use PPP communications with LTE modem.but when I try to check LWIP in [Pinout & Configuration] of IOC file,I can't set [Enabled] of [LWIP Mode and Configuration]It is disabled. I dont know why.Can you explain how to set PPP with IOC file.

I have STM32F407-Discovery Board and want to connect it to the Ethernet using its built-in Ethernet Module, please give me example as I am new to STM32 MCU, Do I need Hardware Editing in STM32F407-Discovery Board for Ethernet functionality or just I need to work in software side?I am Working in STM32CubeIDE.

When generating a makefile project with the STM32U575 MCU it does not generate the CPU= -mcpu-cortex-m33 section of the makefilee.g. it looks like this:####################################### # CFLAGS ####################################### # cpu     # fpu FPU = -mfpu=fpv4-sp-d16   # float-abi FLOAT-ABI = -mfloat-abi=hard   # mcu MCU = $(CPU) -mthumb $(FPU) $(FLOAT-ABI)This gives errors while compiling with a fresh makefile project.

If we use the MCU (STM32F401VE  in STEVAL-MKI109V3) to train our IMU(LSM6DSV16X) for the prediction of certain behaviour.Can we then use the IMU standalone without the MCU for the prediction?If so, Where can those predictions be read from the IMU and in what format?

Hi, I've got a Nucleo F303ze and I'm trying to send and receive data via USB without the ST-Link, so I'm powering the board with an 9V battery. When I connect the USB in CN13 the LD8 turns on but on my device manager there is no new connection.When I use ST-link everything seems to work fine as I can upload the program without problem and the board is detected in the device manager, but it still doesn't recognize anything with CN13.I've tried several cables and USB ports but none work as well as two different boards.I'll add a picture of the board state, it is brand new.Both LD6(PWR) and LD8 are turned on, and LD4 blinks slowly.I'm following this tutorial for the code: https://controllerstech.com/send-and-receive-data-to-pc-without-uart-stm32-usb-com/But seeing as the board isn't even detected and I can't use putty to see if the data is being sent I dont think there is a problem with the code yet.Is there anything I'm missing? Thank you very much.

Hi, sorry for the blatant title, but in this case it's justified.The RTC functions are not just wrong. They are wrong in such a way that pretends to be good, may pass most of tests, and makes finding what's really going on a lot harder.I am working STM32F107VC CPU, and the problematic HAL file is stm32f1xx_hal_rtc.c (firmware package version 1.8.4).Symptom: if I set the date and time using HAL_RTC_SetTime/SetDate, and then read it back, it works fine. But when the device is powered off and on (I have a backup battery), only the time will be correct, and the date will be reset to zero.That is because the HAL_RTC_SetDate function does not really set the date in the RTC hardware, only in the RTC_HandleTypeDef struct fields, namely DateToUpdate field. Please look into the function, and you will notice, that DateToUpdate fields are set according to the sDate parameter, then WeekDay is calculated from them, but they are never used in this function after that point. The hardware RTC counter i

Hi.I am using STM32WL55 for FSK communication.Firmware version is STM32Cube_FW_WL_V1.3.0.In the past, version 1.1.0 was used, but version 1.3.0 has changed a lot.So I'm not sure how to set it up.​​First of all, I want to set SUBGHZ_PHY, but the Enable check box is disabled as follows.And files related to SUBGHZ_PHY and Radio are not visible after [Generate Code].Could you let me know why it is disabled and how I can use it?​Please give me a procedure or method on how to set up and use FSK.​Thank you.​​

MX generated ADC drivers like this: /** Configure Regular Channel */ LL_ADC_REG_SetSequencerRanks(ADC1, LL_ADC_REG_RANK_1, LL_ADC_PATH_INTERNAL_VREFINT); LL_ADC_SetChannelSamplingTime(ADC1, LL_ADC_PATH_INTERNAL_VREFINT, LL_ADC_SAMPLINGTIME_247CYCLES_5); LL_ADC_SetChannelSingleDiff(ADC1, LL_ADC_PATH_INTERNAL_VREFINT, LL_ADC_SINGLE_ENDED);it uses macro LL_ADC_PATH_INTERNAL_VREFINT, not LL_ADC_CHANNEL_VREFINT. As the results, the internal channels are not ADC'ed right, TS is 200+ degree, VREF is always 3.300V and VBAT is 3.6xxV. It happened on L4 series, not WB55 (where the macro is LL_ADC_CHANNEL_VREFINT). -wq

Hello, we want to use the STM32WLE55 MCU in the AI50H Module to build a Node to Node connection in a LoRa Network.So i used the STM32CubeMX Program to build an easy solution that includes only "UART", "SUBGHZ" and "SUBGHZ_PHY" modules. Goal is that i send a sensor value per UART and the STM32 sends this data over Lora.So i have several problems:STM32CubeMX told me to change the linker file because "subghz_phy" is active? what is there to change?i have (in the fresh generated file) several errors after building.. "<file_path>: Invalid Argument" and "fatal error: no input files"can someone help me what i am doing wrong? Sorry for providing not that much information, this is a totally new created project.

Hello All,I'm new to ST products. We are using STM32G041F8P6 in our project. This IC will be programmed through I2C/USART and there's no JTAG available for this chip. Please suggest some low-cost programmers/debuggers.Thank you

According to datasheet and AN5005, LIS2DH12 accelerometer can go to sleep & wake up + generate I2_ACT interrupt when acceleration goes below / above the threshold defined in ACT_THS.Which acceleration exactly is taken into account for this strategy? Maximum / minimum of X,Y,Z? Resultant? Is gravity compensated for or not?
