Hello,Im trying to use CAN on an STM32F042F6P6. The datasheet tells me to remap PA11/12 to PA9/10. How would I do that in CubeMX?https://www.st.com/resource/en/datasheet/stm32f042c4.pdfIf I hover over the grayed out CAN, it tells me that I have to do this in "SYS". Id assume this means the System View, however that doesnt really bring me any further either.   

Can anybody point me to example of two or more ADC channels polling?​I'm trying to measure two channels of one ADC but it looks like it reads one channel twice​Initialization:static void MX_ADC1_Init(void) { ADC_MultiModeTypeDef multimode = {0}; ADC_ChannelConfTypeDef sConfig = {0};   hadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV1; hadc1.Init.Resolution = ADC_RESOLUTION_12B; hadc1.Init.ScanConvMode = ADC_SCAN_ENABLE; // scan all channels? hadc1.Init.ContinuousConvMode = DISABLE; hadc1.Init.DiscontinuousConvMode = DISABLE; hadc1.Init.ExternalTrigConv = ADC_SOFTWARE_START; hadc1.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE; hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc1.Init.NbrOfConversion = 2; hadc1.Init.DMAContinuousRequests = DISABLE; hadc1.Init.EOCSelection = ADC_EOC_SEQ_CONV; //<<<< hadc1.Init.LowPowerAutoWait = DISABLE; hadc1.Init.Overrun = ADC_OVR_DATA_OVERWRITTEN; if (HAL_ADC_Init(&hadc1) != HAL_OK)

Hi all!I have a project in STM32CudeIde that being downloaded via ST-Link works correctly. Also I have a hex file in MyProject/Release. If I compare downloaded via ST-Link code inside MCU with the hex file, they are different. So I cannot use the hex file for my own bootloader because the hex file code is trash (interrupt table different, code different...).How can I get true hex file of code?

Hi hope you guys are well,  When i call the function to turn the BLE on, it starts to advertise but i dont know to get out of that function , means in the main while loop the code is stuck at MX_APPE_Proccess(), i did the debugging but its just looping the same function  (void UTIL_SEQ_Run( UTIL_SEQ_bm_t Mask_bm ){) i want to move to next statements  in the main while loop   FLASH->KEYR =  0x02030405;  while (1)  {   HAL_GPIO_WritePin(GPIOB, GPIO_PIN_1, 0);         HAL_Delay(100);          HAL_GPIO_WritePin(GPIOB, GPIO_PIN_1, 1);          HAL_Delay(100);        HAL_GPIO_WritePin(GPIOB, GPIO_PIN_1, 0);        HAL_GPIO_WritePin(GPIOB, GPIO_PIN_1, 1);    /* USER CODE END WHILE */    if (HAL_GPIO_ReadPin(GPIOC, GPIO_PIN_4) == 0)    {     MX_APPE_Process();   &n

Hello,I was using STM32 Blue Pill board and it was working fine until few hours ago. It suddenly stopped working. I was trying to make the built-in LED (At PC13) blink using Arduino IDE but it's not even blinking when i do Reset now. I've tried Flashing The Bootloader again but that didn't worked as well. Idk what might have gone wrong with it. Is the Reset Button broken " Or It's something else. If anyone knows how i can fix this than please let me know. I appreciate any kind of help.  

I'm considering using a QSPI RAM to expand the RAM of an STM32H7 device (not FLASH).If possible, I'd like to use memory mapped mode. However, when I was doing research on this, I ran across a bunch of posts saying that memory mapped mode for QUAD-SPI RAM is read-only.For example, see this post: https://community.st.com/t5/stm32-mcus-products/is-it-possible-to-use-serial-sram-qspi-with-the-stm32h743/td-p/262301Where is the documentation that states this? I looked through the datasheet and reference manual and see no mention of this. Do STM32H5 devices have this same limitation?

Hello Ladies and Gents,I have following Problem with my App:The Scanrate from given Timer can be in min. 10ms. These ist f=1/0,010=100Hz. So If I configure the Lis2dh to normal or Highres Mode I have a f=1.344 KHz Anybody have an Idea how to increase/decrease the Scanrate to geht all the values of interval?Also I'm bind to USB and the Transactiondelay from max 500ms. Stv

Hi!I am developing a custom loader for a custom H7-board with a OSPI with a page size of 512 bytes (0x200). Naturally the programming via the Write() function needs to be optimized in programming whole pages aligned on boundaries and so on.When debugging with a loading a testfile of 572 bytes (0x23c), the Write() is called twice with these input values from CubeProgrammer:Write()-------------------- Address: 0x70000000 Size: 0x13c Write()-------------------- Address: 0x7000013c Size: 0x100I have stated page size to 512 bytes in Dev_Inf.c so it does not make sense why the first call is not made with a size of 0x200 and the second call is made with the "rest" 0x3c..For other tests it almost appear as CubeProgrammer calls Write() with "random size chunks" and naturally causing the programming to fail.Have I missed something here, what logic is applied in CubeProgrammer?

Hi,Whenever i try to download ST25 embedded NFC library (STSW-ST25R-LIB ----> STSW-ST25R017), I encounter this message: "Not available for download".Same message in last 4 days.Best Regards.

I used a Nucleo F439ZI to develop initial software (with a custom daughterboard) and now have redesigned the whole lot onto a single board with the STM32 MCU.  I'd like to remain able to support both boards in my Cube project as the nucleo one is much easier to modify.I used the pinout -> compatible MCU selector in Cube to find an MCU which digikey stocked and which was the cheapest pinout compatible which met my needs which found the F429ZET6.  I'd have imagined that thanks to the HAL I would simply need to switch "Build configuration" or similar to go between them but this doesn't seem to work it sems I need to completely retarget, code generate the project. Am I missing something obvious? This seems to be the design journey the software encourages me to take.Did I make a mistake in not using the identical MCU (STM32F439ZIT6) to the one on the Nucleo Board?

Hi, I am using G474RE nucleo board and I want to communicate between the UARTs available on the board (UART2,UART1 and UART3). Message is not transmitting complete in to UART1 from UART2 and same with UART3 from UART1 

Hello, i am dealing with an i2c issue.I am trying to trasnmit from my NucleoF401RE (as master) to an ESP32 (as slave). I cant make to ESP32 respond the device address. I take some measures off the SDA and SCL signalsI realized that SDA has cero hold time and i am not quite sure if it is okey.I make also some measure but now using my ESP32 as master and those are the signals:i am not quite sure but i think this is the problem beacuse de ESP32 does not send the acknowledge.Is there a way to put some hold time to my nucleo F401RE ? Right now i am using the I2C in polling mode. I add my config and code: int main(void){  MX_I2C1_Init();  /* USER CODE BEGIN 2 */ Buffer_tx[0] = 0x15;Buffer_tx[1] = 0xF5;  while (1)  {ret = HAL_I2C_Master_Transmit(&hi2c1, SLAVE_ADDR, Buffer_tx, 2,HAL_MAX_DELAY );  }}

Hi, I have set ADC + DMA in H743, I reuse code that work in products every days but today a strange beauvoir happened, ADC work only in debug mode, somebody know this issue?thanks friends.

When I Update WRP option bytes in stm32u585 via program and call OB_launch is resetting device continuously.Here is the code snippet. any other configurations I am missing??

Hi,I am new to STM32 devices. I have a STM32F407 Discovery 1 board.I wanted to generate a 1 KHZ signal with a 50% duty cycle.The timer clock is configured to 84 MHZI am using TIM3 on channel 4. The prescaler is 210 and the counter period is 400 =>84000000 / 210 / 400 is 1000 HZIn my code I have the following: HAL_TIM_PWM_Start(&htim3, TIM_CHANNEL_4); // start PWM on TIM3 CH4 on PB1 pin PWM_Duty = 200; // set duty cycle to 50% __HAL_TIM_SetCompare(&htim3, TIM_CHANNEL_4, PWM_Duty); // set duty cycle of PWM pin, now PWM starts runningHere is what I am seeing on the scope:As you can see the frequency is 992.9 HZ.I am trying to understand the resolution and why it is not 1000 HZ?Thanks for any info.Brent      

If I use CubeProgrammer to connect the internal boot loader of STM32H750XBH6 via USB (pull Boot-0 high), can I program the external SPI Flash through CubeProgrammer? I know it's possible to do this using ST-Link (ps. by stldr) directly, but I can't do it using USB by similiar way. 

Hi, I have an STM32L4x6 processor.I'm reading data using ADC and DMA, and after the HAL_ADC_ConvCpltCallback, I process the data with a Fast Fourier Transform. Originally, in bare-metal, I had a flag in the main loop, and when the interrupt occurred, I set the flag and calculated the FFT(). My processor is currently running at 4MHz. The entire FFT operation took about 140-145ms (measured with HAL_GetTick()).Afterward, I wanted to see the results with FreeRTOS. I created a task that starts when the flag is set to 1 by the HAL_ADC_ConvCpltCallback. However, when I measure it with osKernelGetTickCount(), the FFT function takes three times as long under FreeRTOS compared to bare-metal. I also tried giving the task a high priority and experimented with kernel_lock, but in all cases, it's about 480ms.What could be causing this significant difference?I also tried other tasks like memcpy and looped copying, and in all cases, the tasks take about three times as long under FreeRTOS.Does any

Hello Guys!I'm using STM32F746 NUCLEO board for USB Bootloader application. And I'm using CubeMx 6.9.2 for configuring USB device. when I'm connecting my USB device on CN13 connector and monitoring the Application State in debug ... so its always Staying at APPLICATION_START, Not Changing to APPLICATION_READY state.I got one article on ST Community in that they suggested to use USB host library V3.5.0 and I tried this library but still its not working. USB_OTG_FS Settings:USB_HOST Mode Settings:FATFS Mode Settings:Anyone Knows any thing about it please reply.

HelloI would like to understand the EDMK (Encryption Decryption Master Key). This key is used to decrypt and encrypt BL2 and FIP binaries.Are there any other application of this key? For example, can it be used for LUKS ?Is it possible to access some API to encrypt/decrypt using this key? Or is it reserved to the ROM code?Thanks

Hello, I was experiencing this weird thing lately with my STM32 Blue Pill board's COM Port.I'm using STM32duino (Blue Pill) with Arduino IDE. I've Already flashed the bootloader and installed the drivers for it. when i connect the board with my PC using USB cable, it shows the port in Device Manager but when i disconnect the board and connect it again, it stops showing itself. when i install the drivers again only after that the port shows itself again and leave again when i reconnect the port again.Does Anyone Know What Might Be Causing This ? Any Help Is Appreciated. Please Do Reply If You Know Anything About My Issue ASAP. 

I am using above settings and functions for RTC and One Alarm, also attached with this post as RTC_and_One_Second_Alarm_Setup_using_STM32hxxx.pdf, please review and let me know if you see any issue. Thanks in Advance.

Hello,I am using the LSM6DSOWTR sensor in a wearable device for step counting.As it's known, the LSM6DSO series features an advanced pedometer, step detector, and step counter.I'm observing many steps counted even when the user is not moving (false positives), and I'm comparing the counted steps with other market wearables (twice as other devices).The False-Positive Rejection feature is enabled for better results (PEDO_CMD_REG).The Pedometer Debounce Threshold is set to 50 to avoid false step detections (PEDO_DEB_STEPS_CONF).Despite the high value of the debounce threshold, I have noticed that in resting situations where the user is stationary (e.g., during office work or sleeping), the IMU counts quite a few false positive steps.I have thoroughly read the LSM6DSO datasheet and the AN5192 document.In section 6.1 of AN5192, Pedometer Functions: Step Detector and Step Counter, it mentions the operation of the pedometer functions, but I would like to clarify the following details:How can
