Hello,I updated the HAL libraries for STM32G072RB from 1.3.0 to 1.4.0 (using the CubeIDE and opening the .ioc file and confirming the Migration).However, I can't compile the project any more. Is there something I can do?make -j8 all arm-none-eabi-gcc "../Core/Src/system_stm32g0xx.c" -mcpu=cortex-m0plus -std=gnu11 -g3 -DSTM32G071xx -DUSE_HAL_DRIVER -DDEBUG -c -I/home/david/c/stm32/common -I../Drivers/CMSIS/Include -I../Core/Inc -I../Drivers/STM32G0xx_HAL_Driver/Inc -I../Drivers/CMSIS/Device/ST/STM32G0xx/Include -I../Drivers/STM32G0xx_HAL_Driver/Inc/Legacy -O0 -ffunction-sections -fdata-sections -Wall -fstack-usage -MMD -MP -MF"Core/Src/system_stm32g0xx.d" -MT"Core/Src/system_stm32g0xx.o" --specs=nano.specs -mfloat-abi=soft -mthumb -o "Core/Src/system_stm32g0xx.o" ../Core/Src/system_stm32g0xx.c: In function 'SystemCoreClockUpdate': ../Core/Src/system_stm32g0xx.c:231:10: error: 'RCC_CFGR_SWS_HSE' undeclared (first use in this function); did you mean 'RCC_CFGR_SWS_Msk'? case RCC_CFGR_SWS

Hello,In my project I need to generate 1s on, 1s off PWM signal in hardware.First I checked if my PWM works with simple project, and it does.But following AN4776 for N-pulse waveform generation application example - part 1.LL_APB2_GRP1_EnableClock(LL_APB2_GRP1_PERIPH_TIM1); LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_TIM2);   LL_TIM_DeInit(TIM1); LL_TIM_DeInit(TIM2);   uint32_t Tim2Prescaler= (uint16_t) (80000000 / 1000000) - 1; uint32_t Period2 = 1000000 / 20000;   TIM2->PSC = Tim2Prescaler; TIM2->ARR = Period2-1; TIM2->RCR = ((uint32_t) 32768) -1; TIM2->CCR1 = Period2 / 2; TIM2->CR1 &= ~ TIM_CR1_CKD; TIM2->CR1 |= LL_TIM_CLOCKDIVISION_DIV1; TIM2->CR1 &= ~(TIM_CR1_DIR | TIM_CR1_CMS); TIM2->CR1 |= LL_TIM_COUNTERMODE_UP; TIM2->CCMR1 &= ~TIM_CCMR1_OC1M; TIM2->CCMR1 &= ~TIM_CCMR1_CC1S; TIM2->CCMR1 |= LL_TIM_OCMODE_PWM1; TIM2->CR1 |= TIM_CR1_OPM; TIM2->SMCR &= ~TIM_SMCR_TS; TIM2->SMCR |= LL_TIM

i'm have version 6.2.0i'm trying to install stm32cube MCU package for STM32F! version 1.8.3 or 1.8.0

What I do now:Initialize all peripheral in Default mode (this is the dialogue option)USB_OTG_FS MODE: Device Only | Activate VBUS : VBUS sensing | Activate SOFUSB_DEVICE (as middleware) Class For FS IP: Communication Device Class (Virtual Port Com)Default clock configuration (no changes from as it proposed by Cube)I generate it as MakefileAnd just build it and flash it. The only COM port I saw it's ST-Link (com3)As sanity check: usb cabel connected to both usb_connectors on board (not only to ST-Link micro usb) after connecting usb to main part of the board LD8 (green) lights up.The blinking blue led just for debugging purposes, to make sure that board was flashed.But I don't see another COM port into device manager, only the ST-link one:

Hello,I run into problem for selecting TIM2 as my pwm output. As it turns out, it is only output capable. But I need to get processor independent 3kHz 50:50 PWM signal with no AF functional PWM.Any simple idea how can I toggle with 50% 3kHz duty cycle this GPIO? (PA15 on STM32L412C8)I Am thinking of using DMA, just have no idea how to do that, since I can't use ODR register,I have multiple pins that should not change, and with BRR BSRR, well, it is two address, so what ? Do ping pong DMA with single transfer and circular buffer ?Any ideas are welcome :)

I'm currently using TIM2 on an STM32F373 as a 32bit quadrature encoder interface, however I need to extend this to 64 bits. Can I cascade a second 32bit counter (e.g. TIM5) as a slave whilst still maintaining the ability to count up & down ? Thanks

I've edited this post to make it more useful to others.We are well into development of a board at work using an STM32F072RBT6 MCU. I just wrote a quick from scratch test using a NUCLEO-F072RB board to verify things. I'm not sure of the exact problem, but it appears TIM2 is adding 1 to the CCR. I have the timer configured that each count is 1 us, using PWM mode 1, and down-counting. If I write in a CCR of 0, I get a 1 us pulse. If I write in a CCR of 1, I get a 2 us pulse. If I write in a CCR of 2, I get 3 us pulse. You get the picture. I attached the demo project as a zip. I also setup TIM1, but used up-counting and it works as expected. main.c has some comments in it.

I'm seeing shoot through on the coil drives for the STSPIN32F0A custom implementation in the attached schematic. The attached scope shot has these channels:CH1: 24VCH2: CoilCH3: Low Side GateCH4: High Side GateYou can see the 700ns of deadtime when the high side gate drive drops from 35V to 24V. If the gate was just held up capacitively, the diode should be conducting there bringing it to near zero, but instead it is perfectly flat, not held up capacitively but appears driven. I wonder if this if this relates to the bootstrap capacitor somehow buggering the high side gate drive. I’m not familiar with these bootstrap circuits. How does one determine the correct bootstrap capacitance? Also, I noticed the STEVAL-3201 high side gate isn't boosted to 35V but instead is 24V or 0V.

In function HAL_DMA_IRQHandler() the lines 872, 914, 949 modify the hdma->State variable after __HAL_UNLOCK(hdma) has been called.STM32 HAL is full of bugs, especially race condition related ones, but this one seems to be more urgent, because multiple instances of the DMA are used together with many other peripherals in different combinations. I'm reporting this for F7, but drivers for other series also should be checked for the same.

Dear All, is there a possibility to implement another driver for other commercial reader/writer like the uTrust 3720 into the Software STSW-ST25PC001, or a way to implement it by myself with the STSW-ST25PC002?Or where can I purchase the Feig controller?Thank you in advance.

Hi, I've got a STEVAL-MKI173V1 board hooked up to my uC. I ported over the driver from:https://github.com/STMicroelectronics/STMems_Standard_C_drivers/tree/master/lsm303agr_STdC I'm able to read valid magnetometer values but almost always get 0's from the accelerometer. Here is the code: uint8_t whoamI, rst; int pDataM[3]; int pDataA[3]; int16_t pDataARaw[3]; int16_t pDataMRaw[3]; float acceleration_mg[3]; float magnetic_mG[3]; uint32_t ret;   whoamI = 0; ret = lsm303agr_xl_device_id_get(COMPASS_ACCL_ADDR, &whoamI);   //if ( whoamI != LSM303AGR_ID_XL ) // while (1); /*manage here device not found */   whoamI = 0; ret = lsm303agr_mag_device_id_get(COMPASS_MAG_ADDR, &whoamI);   //if ( whoamI != LSM303AGR_ID_MG ) //while (1); /*manage here device not found */     ret = lsm303agr_mag_reset_set(COMPASS_MAG_ADDR, PROPERTY_ENABLE);       do { lsm303agr_mag_reset_get(COMPASS_MAG_ADDR, &rst); } while (rst);   &nbs

Is it possible to run the firmware from an external SDRAM?There is an example for h750, but it does not work with h747.I go to the address I need, but I get a hardfault into bootloader for first command into external sdram

How can I determine the offset values? After determining I will use the following example.https://github.com/STMicroelectronics/STMems_Standard_C_drivers/blob/master/lsm6dso_STdC/example/lsm6dso_offset.c

Hi there, is it possible with any of the currently manufactured ToF sensors of the VL53L* family and the software that is available to private customers to obtain a depth image, or the raw sensor values for each SPAD to reconstruct a depth image?I experimented with a VL53L1X sensor by Pololu with the ported API for Arduino Uno R3, which only gives me a single range in millimeters, which from the API code appears to be a median of the valid ranges of all SPADs. I want to create difference depth images to the previous measurement, for which I would need access to all range values and do the aggregation (min, max, avg, median, ...) myself. But it seems that the median is acquired from the sensor via I2C already, not calculated in the accessible API code.I am aware that I can use the programmable ROI to create a depth image of medians over 4x4 SPAD regions of interest, but this would take too long (time budget in the application is ~100 ms per measurement) and is greatly reducing the resol

I wonder if someone can provide me with an example how to use the watchdog in a STM32F767.I have tried the following code but it don't get a reset!static WWDG_HandleTypeDef hwwdg;static bool wwdg_inited = false;static void EnableWDG (void){ if ( ! wwdg_inited ) {  hwwdg.Instance = WWDG;  hwwdg.Init.Prescaler = WWDG_PRESCALER_8;  hwwdg.Init.Window = 64;  hwwdg.Init.Counter = 100;  hwwdg.Init.EWIMode = WWDG_EWI_DISABLE;  if (HAL_WWDG_Init(&hwwdg) == HAL_OK)  {    if (HAL_WWDG_Refresh(&hwwdg) == HAL_OK)      wwdg_inited = true;  } }}It seems that the the API has been changed. The HAL_WWDG_Start() no longer exists...

Hello,I use a STM32WB55RGV7 microcontroller. Doing the hardware layout I'm confused about the antenna filter: - I can't get the band pass filter LFB182G45CGFD436 in small quantities, which is used in the P-Nucleo-WB55 - the low pass filter LFL212G45TC1A007, wich is used in AN5165, is end of life in about one year - AN5165 uses also another low pass filter MLPF-WB55-01E3, which makes a part of the other componets unnessesaryCould you give me a suggestion which of these filters I can use in my design reasonably future-proof?Thanks in advance.Holger

https://eds.st.com/dcdc/I want 9-30V to 8V and I don't have any 3.3V voltage in my circuit. Is it okay if I don't connect anything here?  

I have the same problem as described and unanswered here: https://community.st.com/s/question/0D53W00000IUzefSAD/nucleo-h745ziq-drawing-current-spikes-from-usb-power-port-producing-noisy-5v i.e. bursts of current spikes each 18 ms.The particular board is Nucleo STM32H743ZIT6, old chip revision Y.It does no go away even when holding the reset button. Not even when the st-link is kept in reset by installing SB107 and the ethernet PHY is held in reset by removing SB177. There is no SMPS on the board.I measured with two different oscilloscopes, either with voltage probe between Vdd and Vss as well as with a current probe (on a short wire jumper across the Idd header). I tried powering the board from USB or from a benchtop power supply. I tried heating up and cooling down the MCU, but the pattern never changes. The same pulse sequence repeats every 18 ms.Is it some kind of bootloader or a debugging interface that is trying to establish a connection?I would ignore it if it did not make any d
