I want to know how to fold curly braces. There are too many codes in the interface, so i hope the brace can be folded.

I have a new product using the stm32l486, and the GPIOG pins mentioned in the title do not appear to work as outputs, even though they are configured identically to the GPIO pins I am using for ports A-F. I cannot find anything in either the datasheet or the user manual about any pecularities to port G. But when pins in the GPIOG.ODR are set to '1' they definitely do not go high, and they are still read back as '0' on GPIOG.IDR. I also do not see anything in the errata for the stm32l486. I am correct in thinking that port G works like the other ports on this part?

Hi, I have STM32F407VE and this display which require 5V power:Is it ok, to connect it to 5V and to FSMC pins? I wont demage FSMC pins?

When I run the updater, and press 'start', an error occurs during the step, "Install IBUUI drivers". The error message isError installing C:\Program Files(x86)\STMicroelectronics\SPINFamily Evaluation Tool 3.2\Updater\Drivers\WinXP\IBUUI.inf driver. Access is deniedThis file is present in the location and has read access by all groups listed under the file properties. I tried to run the IBUUI Board Updater as Administrator (right-clicking on it and choosing that option) but this did not change the behavior.I also tried the alternate procedure to use STM32 ST-LINK software as described in the dm00268136 Spinfamily evaluation tool document, however once I try to connect to the MCU target, it says "No ST-Link detected." It is difficult to believe that I'd need another piece of hardware not required for my project in order to make the hardware I purchased work, since all the documentation on the EVAL6470PD says all I need is the EVAL6470PD and the STEVAL-PCC009V2.The environment is Windows

Hello,I have connected a BNO055 Sensor via I2C to a STM32WB Nucleo board. The sensor data is send by a BLE Service without problems after powering the device.However, if I change the code and upload via STM32CubeIDE or press the reset button on the device, the I2C connection seems broken... I do receive a HAL error from time to time... Question: is there a way to securely reset all pins apart from pressing RESET or is this more likely to be my software's problem?

Hello, i have a strange problem with x-nucelo-nfc01a1 shield.I get an i2c timeout but under different conditions it occurs in different places in code.My setup is nucelo board with stm32L073RZ and X-NUCLEO-NFC01A1 shield, and to communicate with M24SR module i am using xcube libraries, which i downloaded from st.com site.Case 1.I2C is configured to 100kHz.I2C timeout occurs during initialization phase. From my observations it looks like the transmission holds during sending verify command (M24SR_Verify()).The I2C_WaitOnTXISFlagUntilTimeout() function in HAL_I2C_Master_Transmit() returns I2C_TIMEOUT and it is always in the half of transmission.The verify command is 24 bytes length, and when timeout occurs hi2c.Instance.XferCount is equal to 12.So in result i cannot even initialize the module.Case 2.I2C is configured to 400kHz or 1000kHz.Initialization phase passes with success. I can even write and read an URL using TT4_WriteURI() / TT4_ReadURI().But when i try to write for example vcar

Hi,Please can someone help me, I am quite new to this hardware.I have a MKI109V3 eval board and trying to test MKI197V1 LSM6DSOX adapter. I've downloaded the Windows software package and installed Unico V9.8.1.0 and the COM port driver V1.5.0. I've also updated the firmware of the MKI109V3 to V3.6.36 via STM32CubeProg.In Unico, when I try to select device MKI197V1 I receive this message:"ERROR: The adapter board has not been recognized.The WHO_AM_I register does not match the device selected."I am unsure why I'm getting this error message. Any help would be much appreciated.Many thanks,Liam

I have a VL53L1X connected to a multi-slave I2C bus hosted by a broadcom bcm2835 running linux (4.19). I have configured the `vl53l1_platform.c` from the api ("stsw-img007") to use the <linux/i2c-dev.h> interface with tracing and see bi-direction communication. However, after that `StartMeasurement` call, GetMeasurementDataReady consistently reports that data is not ready, despite waiting for minutes. Since there is no published i2c command/register list/help (?), I am working in the dark. Can someone familiar with this device's i2c interface take a look? Here's the i2c trace log:Fail; line: 173, expected: 2, got: -1, errno: 121Fail; line: 173, expected: 2, got: -1, errno: 121Fail; line: 173, expected: 2, got: -1, errno: 121Read register: 0x00e5 = 03wrote register: 0x0000 = 00wrote register: 0x0000 = 01Read register: 0x00e5 = 03Read register: 0x00e5 = 03Found (booted) device.Read register: 0x010f = ea cc 10Validated device.Read register: 0x002e = 00wrote register: 0x002e = 01Read

Hello to everyone. I am teaching an embedded system lab courses and this is our first year with a STM32F767ZI Nucleo board. We are at a point where we want to exploit the on-board temperature sensor to generate some input data. In our first experience with the sensor we are setting ADC1 in single channel, continuous conversion mode, and we are working with interrupts. The first thing I notice is that, if I apply the conversion formula on the MCU reference manual (RM0410 pag. 466, T = (V_sense - V_25)/Avg_Slope + 25), where V_sense is the value read by the temperature sensor and all the other data are on the datasheet, I obtain completely bogus values for T, of the order of 100 °C. Instead I found an application note (AN3964), that discusses the use of the temperature sensor for STM32L1x microcontrollers, and suggests a two-point approach based on the calibration data TS_CAL1 and TS_CAL2 to calculate the temperature. This yields temperature values much more realistic, closer to that of

Hi,I'm currently developing a board where I use STM32L433RC as my main unitof processment. This board will have an SD Card to store some data and later ontransfer it via UART. To achieve this, I must use an UART to Serial Portconverter.After some research on MCU reference manual, I saw that it has an USB Peripheral Interface where I could connect D+ and D- directly to the MCU. Thus, if this worked, I wouldn’t need to have the converter in my board. However, I’ve some questions:Is it possible to use USB peripheral as a Serial Port?The learning curve of this peripheral it’s hard? Since I already have code to UART, which in fact is to simple, will I spend a lot of time doing the same thing to USB protocol?I’m not thinking about using and external clock. To use USB peripheral do I need one?Is it easy to change the Serial Port name? So, when I connect the MCU to the PC this custom name its used. Thanks in advance.

This just looks like a comment but it seems a code outside these comment have different affect./* USER CODE BEGIN 1 *//* USER CODE END 1 */

If anyone could help me point to location in the API where I could implment "Autonomous low-power mode".And on "Autonomous low-power mode" what is the expected current draw?for a battery operated project what should I tweak in the API to get more power savings?Thanks in advance.

This actually makes sense because the ODR is 26,667 kHz which means that between two samples are 37.5 us this would make three 12.5 us ticks. 25 us wouldn't make much sense.

I must say that the recently updated TouchGFX documentation is excellent. Great job! I apologize if I am missing the obvious, but is there a way to pass more than one value by way of an "action" to a Custom Container?I am referencing the following tutorial:https://support.touchgfx.com/docs/tutorials/tutorial-05/I am working on a Custom Container with a Scrollwheel in it and I would like to add a custom action to be able to change the text of a specified element (a second parameter) programmatically. I tried the "custom" and when trying to add the action, I was not able to get it to accept a multiple parameter virtual function or when selecting "Execute C++ code".Any help would be appreciated.

I'm a beginner in embedded systems. I'm creating a software where some leds are blinking in the main while loop. I would like to put the MCU into stand-by mode when connecting a certain pin. I want to return to normal execution when this pin is disconnected. Right now I'm using a SYS_WKUP pin to exit the stand-by mode. Could I somehow use the same pin to enter stand-by mode. What is the best way to implement this?Right now i can enter stand-by mode in the middle of the main loop and exit stand-by mode when connecting the pin, but I don't know how to enter the stand-by mode as i connect the pin. I have the NUCLEO G031K8 and I'm programming with STM32CubeIDE.

hi dear.​I am making a QWERTY Korean input method.It was confirmed that Unicode is used to express characters using the touchGFX designer. However, Font can only output codes in EUC_KR. In the case of the Korean input method, one code is produced by combining, but one complete code is produced through a combination of 2 to 4 codes. Even during the combination, it is necessary to express the letters, but this is a problem because the entire font of Unicode cannot be output. For example, the word "hoho". When this is input as an input device, the screen output order should be displayed as 'ㅎ'-> '호'-> '홓'-> '호호'. However, '홓' is in the Unicode Font but not in EUC_KR, so it is treated as Blank. How can I solve these problems ????If you input "홓" in TouchGFX Designer Resource, nothing is displayed.

I am doing a pcb layout with a STM32L432KCU6 and using 100% of its 32 pins in my project. BOOT0 signal is on pin 31 on that MCU and in my schematic I have a digital output on that pin (PH3). There is no pull-down/up on BOOT0 on my design. Programming will be via SWIO/SWCLK/SWO/RST/VCC/GND and I want it always boot from flash.Is there any way to program the chip (write some config bits) to disable the use of pin BOOT0? How is that done?I am new to SMT32 micros.REgards.

Float in printf doesn't seem to work in new projects created in stm32cubeideIf i create a project in sw4stm32 it works, there, it also works if i import the sw4stm32 project, it does not work if i create a new project in cubeideIn all cases the option -u _printf_float is used, but in case of new cubeide project, this setting is somehow ignored and the wrong prinf is included, visible in mapfilegood (imported project):../arm-none-eabi/lib/thumb/v7e-m/fpv4-sp/hard\libc_nano.a(lib_a-nano-vfprintf_float.o)bad(new project):../arm-none-eabi/lib/thumb/v7e-m/fpv4-sp/hard\libc_nano.a(lib_a-printf.o)

hey!I'm using timer 1 in OC mode with toggling the output. I also want to change the timer overflow value with the values predefined in the buffer.I define buffer as:uint16_t data[5] = { 50, 50, 100, 50, 50};Then in main I call:HAL_TIM_OC_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *) data, 5);Hardfault strikes inside HAL_TIM_OC_Start_DMA:htim->hdma[TIM_DMA_ID_CC1]->XferCpltCallback = TIM_DMADelayPulseCplt; htim->hdma[TIM_DMA_ID_CC1]->XferHalfCpltCallback = TIM_DMADelayPulseHalfCplt;My question is how avoid this. Attached Cube initialization of TIM and DMA. Alternatively, maybe there is different approach. My goal is to get signal without interrupts that looks like this with exact frequency: 0 1 0 1 0 1 1 0 1 0 1Thanks

So this might be a easily answered question, and I think I know the answer, but I just want to confirm for safety:If a bootloader program for an stm32l4 (or any family of chip) is set up to run at a different clock frequency than a firmware package on the same chip, can that be potentially harmful for synchronous operation between the two applications? For example, the bootloader starts first every time at 24 MHz, and then jumps to the firmware memory address, but I need the firmware application to run at a higher rate (48MHz). I cant change the bootloader at this point in time, so I wanted a second opinion if that can cause conflicts. I feel like no, because each application has its own start up items on initialization (including clock setup) so I feel like its ok. Am I missing something important?
