Hello:There is a post on this same issue titled "TIM16 PWM signal generation...". The fix here was to set the AOE bit in the BDTR register. In that thread they were using LL.I am having a similar issue where I am unable to get the PWM output signal on PA.6. The code base was generated using CubeMX, this is the initialization code:#define PULSE1_VALUE      (uint32_t)(7999)       /* Capture Compare 1 Value */void MX_TIM16_Init(void){ TIM_OC_InitTypeDef sConfigOC = {0}; TIM_BreakDeadTimeConfigTypeDef sBreakDeadTimeConfig = {0}; htim16.Instance = TIM16; htim16.Init.Prescaler = (uint32_t)999; htim16.Init.CounterMode = TIM_COUNTERMODE_UP; htim16.Init.Period = 15999; htim16.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; htim16.Init.RepetitionCounter = 0; htim16.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE; if (HAL_TIM_Base_Init(&htim16) != HAL_OK) {&nb

Hello, please help me.I use stm32f103rc mcu, stlink v2 and keil uvision5.So executing AFIO->MAPR |= AFIO_MAPR_TIM2_REMAP_FULLREMAP;causes stlik connection error.Algorithm:Flash the MCU with keil uvision.Step to remmaping line in code. In this stage everything works fine."Cannot access target" "shutting down debug session"After this debugger no longer sees MCU. "No target connected" "error: target dll has been cancelled.

i try to make numeric keypad.What I want to do is to click on the TextArea so that the numeric keypad pops up.If there is an example, it would be better. If not, how do you implement it?Is there any way to output a keyboard example to modal windows?

Hi, I'm trying to load jpeg files in TouchGFX by using the JPEG Loader Library. I have downloaded that from the Git using the link given in TouchGFX Forum. I have added the Library in my project and tried to load a jpeg image. The image was not loaded, the image is placed in the working folder alone. I have set the break point and checked if the file is opened successfully or not. The file was opened successfully but i didn't the image in simulator output . Suggest me a solution for this issue.

Hello everyone! Please, i need help, and i`ve tried everything i could but still cant solve the problem. The thing is that i need my CircleProgress to move using moveAnimator when the screen in entered. So ive added all the lines in the code but still got an error error: redeclaration of 'touchgfx::MoveAnimator<touchgfx::CircleProgress> temperature_screenView::circletemperature'Thanks a lot and looking forward to get some help.

I used STM32Cube to generate a project for TrueStudio on the STM32WB.My target is the STM32WB55 Nucleo.But the project will not compile. Other posts say check the project target settings. There is no selection for STM32WB.Do I need to add another support package?If so, how do I do that?

The problem I´m experiencing is already "fixed":https://community.st.com/s/question/0D50X00009q2bdeSAA/solved-problem-running-stm32cubeprogrammerWhen running the program STM32CubeProgrammer, an error message appears, saying:"CubeProgrammer_API or one of its dependencies is missing. Please try reinstalling the program of check your java architecture"STM32CubeProgrammer is in verison 2.0.0 now.Any idea?

I've adapted the DAC signal generation example from the HAL samples to my project, but I cannot get any signal from DAC2.Using CubeMX, I configured TIM6 and DMA1 like this:/* Includes ------------------------------------------------------------------*/ #include "dac.h"   /* USER CODE BEGIN 0 */   /* USER CODE END 0 */   DAC_HandleTypeDef hdac; DMA_HandleTypeDef hdma_dac2;   /* DAC init function */ void MX_DAC_Init(void) { DAC_ChannelConfTypeDef sConfig = {0};   /**DAC Initialization */ hdac.Instance = DAC; if (HAL_DAC_Init(&hdac) != HAL_OK) { Error_Handler(); } /**DAC channel OUT2 config */ sConfig.DAC_Trigger = DAC_TRIGGER_T6_TRGO; sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE; if (HAL_DAC_ConfigChannel(&hdac, &sConfig, DAC_CHANNEL_2) != HAL_OK) { Error_Handler(); }   }   void HAL_DAC_MspInit(DAC_HandleTypeDef* dacHandle) {   GPIO_InitTypeDef GPIO_InitStruct = {0}; if(dacHandle->Instance==DAC) { /* USER

Hello everyoneI am having trouble understanding the relationship between the registers and the callback functions for my application. Briefly put, I am transferring 2 values to the DAC via DMA using TIM6 as interrupt at a rate of 50 Hz. I want to sample another value after each of the two DAC values appears at the output, and for that I set flags in the callbacks to start the ADC in my main loop. Intuitively, I would think that HAL_DAC_ConvHalfCpltCallbackCh1 is called after the first value appears at the output, and HAL_DAC_ConvCpltCallbackCh1 is called after the second value appears at the output, but it seems as though the data registers indicate otherwise when I look at the oscilloscope timing diagrams.The DAC is set up with the following parameters:TIM6 trigger out eventDMA mode circularTIM6 is set up with the following parameters:APB1 timer clock is 84 MhzPrescaler is 8399Counter period is 199This gives me a 50 Hz interruptTrigger event is set to update event I start the DAC and

My STMF103 user interface processor needs two modes of operation. One needs to be as fast as possible updating the TFT or TX/RX data, and the other can be slower when it is just monitoring keys and switches. To save power I was thus thinking of using an 8MHz crystal and setting the Clock Configuration Register PLLMUL to *16 and PLXTPRE to 1 which I think gives a main clock of 4 MHz and a PLL clock of 64 MHz. Then I would use the same register's System Clock Switch bits to switch between PLL (10) and HSE(01) to give a Fast and Slow mode.My question is can this be done seamlessly in the processor possibly every second or two without the processor having some noticeable dead time during switching ? Also are 4 MHz and 64 MHz the greatest difference I can achieve as I assume I can't turn the PLLXTPRE on and off as it will disturb the PLL ? Even a 1MHz clock would be more than enough to monitor the input switches, but as the processor does the switch scanning it can't be put in sleep mode.Ob

In my debugger settings I got there is some SWO frequency difference means before 2 or 3 days its frequency value is 10Mhz but now it is only 2Mhz and from last days I have getting some errors. So plz tell me that such errors are coming due to this change or not and how to re change SWO frequency ?

Hi everyone,I recently found myself having spent a lot of time working to get I2C to work on the STM32F103RBT6 (the problem: I2C begins life in the BUSY state).This is apparently due to an ADC noise problem, as described in this errata (p. 26):https://www.st.com/content/ccc/resource/technical/document/errata_sheet/7d/02/75/64/17/fc/4d/fd/CD00190234.pdf/files/CD00190234.pdf/jcr:content/translations/en.CD00190234.pdf#page26I observed that my Nucleo64 MCU is the "x" revision, which falls under the errata. I am curious: Does ST happen to manufacture a newer revision, which fixes these problems?

​Could you provide demo source code on the board STM32L4R9I-EVAL. I bought the STM32LR9I-EVAL board and the current demo program is very cool. I need the demo source  code to study. Thanks!

Hello,A project created in truestudio generates a HardFault_Handler.There are 2 PCBs I made. PCB A and PCB B are the same circuit and components. I have confirmed that the operation is correct while writing the code in PCB A.However, there was a problem with PCB B. My program is Fatfs + USB HOST MSC.It repeats until it becomes f_open with while statement.If (f_mount == FR_OK) to f_mount seems to be no problem. However, f_open fails to pass, and the process goes to HardFault_Handler.How do I debug HardFault_Handler?

Hi,I'm using the USART function HAL_UART_Transmit for debugging.Most of the time everything works well.But sometimes the HAL_UART_ErrorCallback is called... And all my program freeze.Could you help me with these 2 options (first is best for me) :how can i get back to a functionnal state after a HAL_UART_ErrorCallback call ?how can i check if UART is ready to send data before using HAL_UART_Transmit ?Regards

Hi, how much is the additional current consumption enabling the FSM on LSM6DSOX? Regards

Hi All,I'm working with an STM32f091xC on a new design and I'm currently tryingto enable stop mode to conserve power without fully entering standbymode. I seem to be entering stop mode properly, but I'm having quite abit of trouble exiting stop mode.I created a sample application using Zephyr RTOS that targets the nucleo_f091rc. It configuresthe user button as an interrupt source. The Main thread goes into stop mode after 5 secondsand the user has to press the button to wake it up. I also configured the main thread to togglethe on-board LED every 100ms to indicate the main thread is running. I have attached the source code for the example for your review. Although this was implemented with anunaffiliated RTOS, the STM32 LL and HAL support is pretty identical to the STM32Cube librariesand other CMSIS code that's available for STM32 development.The general pattern I'm following for entering/exiting stop mode is as follows:* Set the regulator state in STOP mode: LL_PWR_SetPowerMode(LL_PWR

I'm trying to debug a 429 FreeRTOS app using LwIP, which periodically has a huge (1.5 second) delay whilst trying to pump out messages. Using Atollic 9.1.0, Segger debug code on Nucleo-429ZI board. I can stop the application when it pauses, but the FreeRTOS plug-in is not being helpful.In particular, I cannot see the current context for each FreeRTOS task in the debugger as expected (I cannot see the source line where each task is blocked).What's the secret sauce to get this to work properly?I have the following enabled (as I've found necessary for debugging FreeRTOS apps using other toolchains):#define configTASKRETURNADDRESS 0 // place 0 task return address on stack to help FreeRTOS-aware debugger (GDB unwind thread stack) #define INCLUDE_xTaskGetSchedulerState 1 #define INCLUDE_pcTaskGetTaskName 1 #define INCLUDE_uxTaskGetStackHighWaterMark 1 #define configGENERATE_RUN_TIME_STATS 1 #define configUSE_TRACE_FACILITY 1What am I missing?Thanks!Best Regards, Dave

We use B-L072Z-LRWAN1 (Murata TypeABZ) dev board, where we were able to set-up clock sources to use HSI (@32MHz with PLL - HW_SetHSEasSysClock(void)) instead of HSE during Sigfox transmission. From the firmware perspective, everything is fine, but we were unable to receive data (Sigfox infrastructure), while the same HW with HSE is OK.As the sigfox stack is closed, we don't know if we can do more...What is the reason behind HSE usage? Is it the hard-requirement, or not? Is it possible to set-up HSI somehow?

Posted on June 19, 2017 at 20:00We're using the LIS2HH12 accelerometer and there's a temperature sensor listed in the datasheet accessible via the temp_L and temp_H registers (16 bits).However the numbers I get don't make any sense.The datasheet mentions 'Temperature sensor output change vs. temperature' of 8 digit/�C11-bit resolution, -40 to 80C range and that the it uses two's complement, but I can't find a way to make the readings return any meaningful value.What do these temp_L and temp_H numbers really mean? Thank you.#lis2hh12 #temperature-sensor
