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?

I can't find the update option in TouchGFX designer software. Do I need to uninstall existing designer manually and download X-Cube-TouchGFX package again and install as a new software to update. I know that TouchGFX generator can be updated from the CubeIDE itself. But the problem is with the DesignerThank you

While programming OptionBytes or FW on STM32WLx5 most of the time is OK.In CubeProg I have noticed, that on some MCUs, when I get reading of RDP 0xFF or 0, the next action to program something write related, it could not be done and it's failed.Statistically it's happening too often, 4 failed of 11devices ....(I had also one device, that MCU was fresh and it was already in this state.. had RDP already 0xFF - no write action possible)I can also assure, that I did not programmed any protection at this stage, it's to early.Is there any workaround to overcome this write lock state?Have checked the topics in the community, for example this.But it seems different flow to the same consequence ?If someone can help me understand this situation?What I already find out:Could it be that MSI clock 48MHz got preserved into bootloader mode? (Erratum System 2.2.2 explains high frequency problem)Could it be difference using the ST-Link v2 or v3?By no means FW is programming any OB bytes or something r

Hello ST,I am trying to install x-cube-smcard package via cube mx.I am unable to do so. I get an error everytime.Please let me know how to install the same.https://www.st.com/en/embedded-software/x-cube-smcard.html

I can already read the text correctly. But my project needs to use max6675 to write sensor signals and write them to NDEF, What should I do with MX_NFC7_NDEF_URI_Init?

Hi everybody,I am working with AZURE RTOS and I have implemented an HTTP web server application. I started from the example available in CubeIDE. Everything is working properly but now I need to modifiy the HTTP web page. For this, it is necessary to generate a .bin file from the .js, .css and .html files:Could somebody help me with this issue? I think it should exists a script or something like that for it.Thanks in advance.

I have ported the example code over to STM32H743i-Eval and have it compiling OK. But testing is another issue as there is little information to go on for how to set-up a client PC and connect to the ethernet port on the eval board. I am assuming that the webserver gets html pages off of the sd card and makes them available to what ever is connected to the network port but there is no detail regarding settings on the PC or an IP to browse, etc.Anyone have experience with this or know where some more detailed documentation might exist?

I have been testing the internal temperature sensor on the STM32 Nucleo-L452RE recently. I'm trying to measure the ambient temperature using this sensor, thinking that it shouldn't vary more than about 2ºC compared to the internal temperature of the microprocessor, but the readings are always several degrees higher than the temperature measured by external thermometers and sensors, despite following all the steps available in the documentation and many other forum codes for configuration or calibration.For example, I am currently reading the temperature with the code below, which shows approximately 32ºC. However, I am in a room with good ventilation, the air conditioning is on at 24ºC, a thermometer measures 24.5ºC in the room, and an external temperature sensor measures 26ºC above the microprocessor.In addition, when I turn on a LED with a button or do anything else with the board, the temperature increases up to almost 34ºC.I am unsure of what else to read or test to obtain an accur

Hi everyone, I am starting to program a board with stm32 (stm32f103c8t6) and I have the following problem.I have two codes to make a led blink, but one works and the other doesn't work.Code 1 (not working)#include "stm32f1xx_hal.h" #define LED_PIN GPIO_PIN_13 #define LED_PORT GPIOC void SystemClock_Config(void); static void MX_GPIO_Init(void); void Error_Handler(void); int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init();   while (1) { HAL_GPIO_TogglePin(LED_PORT, LED_PIN); HAL_Delay(500); } }   void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};   RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_ON; RCC_OscInitStruct.HSEPredivValue = RCC_HSE_PREDIV_DIV1; RCC_OscInitStruct.HSIState = RCC_HSI_ON; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON; RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE; RCC_OscInitStruct.PLL.PLLMUL = RCC_PL

I have been trying to debug my custom Azure RTOS NetXDuo application (which is based on the Nx_Tcp_Echo Server example code). My application gets stuck in a loop that it cannot return from after reading the socket_state of an established socket. The application runs correctly, but at some point (for some as-yet-unknown reason) the socket_state changes from NX_TCP_ESTABLISHED to either NX_NOT_CONNECTED, or NX_NOT_LISTEN_STATE. Based on the code of the example, the application interprets this as IDLE state, which is not correct. At this point a client can no longer connect to my server application.Here's the code.while(1) { ULONG socket_state;   TX_MEMSET(data_buffer, '\0', sizeof(data_buffer));   /* get the socket state */ nx_tcp_socket_info_get(&TCPSocket, NULL, NULL, NULL, NULL, NULL, NULL, NULL, &socket_state, NULL, NULL, NULL);   /* if the connections is not established then accept new ones, otherwise start receiving data */ if(socket_state != NX_

In the STM32L431, datasheet does not show PA11 as configurable to an ADC.

I'm using ST's USBPD middleware library and have it successfully working as both a source and a sink. However, I have a use case where I will need to de-initialize the USBPD library and reset the state machine back to it's initial state. Ideally when this happens, the loadswitch opens and power to the accessory is killed. I can't find an easy way to fake a dettach event, or even to de-initialize the USBPD library and reset the internal state machine. Are there functions that support this?

Hi everyone,The screen hierarchy is like below,--------------------------------------------------View|-->MyCustomContainer|------> PopupCustomContainer (under the MyCustomContainer)------------------------------------------------------------------------------------------------I can handle the click/drag event in MyCustomContainer which is under the view.I created another custom container that is a pop-up screen to show on MyCustomContainer. I want to handle the click-and-drag event in PopupCustomContainer but can't.View::handleClickEvent(evt); cntAirConditioner.handleClickEvent(evt); // my custom container that have a custom container.In the view screen, I called these functions but in this situation, the events are triggered twice on MyCustomContainer. If I just call the "View::handleClickEvent(evt)", I can handle the events in my custom container but I can't handle the other custom container which is in my custom container.I hope the explanation is clear.Thanks for your help.

Hi, I'm using an STM32H745IIT6, in the package I have there are also the SMPS pins. But in my application I don't have to use the SMPS.The question is, what should I do with these pins:Searching the internet, I saw that someone connects them all to ground, but I haven't found any explanatory articles or clear indications. Can you tell me how should I connect these 4 pins when I'm not using the SMPS?Thank you.
