Solved

I everyone ,I'm working on a STM32WB35I've build a small custom server app with just a simple batt level service it works and advertise perfectly if I don't enable LPM as soon as I enable LPM it don't advertise anymoreit looks as if CPU2 and RF are down too as default BLE app disable OFF lpm mode it goes only in STOP LPR modeon my custom pcb I have no LSE so I rely on HSE when running and MSI or HSI when in stop or offwhen  comparing with BLE HeartSensor reference exemple I dont understand how it keeps advertising when  in STOP modemy main concern is on BLE HeartSensor exemple when going in stop mode it calls   static void EnterLowPower(void) { /** * This function is called from CRITICAL SECTION */ while(LL_HSEM_1StepLock(HSEM, CFG_HW_RCC_SEMID)); if (! LL_HSEM_1StepLock(HSEM, CFG_HW_ENTRY_STOP_MODE_SEMID)) { if(LL_PWR_IsActiveFlag_C2DS() || LL_PWR_IsActiveFlag_C2SB()) { /* Release ENTRY_STOP_MODE semaphore */ LL_HSEM_ReleaseLock(HSEM, CFG_HW_ENTRY_ST

I believe there is an error in the STM32G4 Series Reference Manual regarding the width of TIMx_ARR for timers 3 and 4.The reference manual shows a width of 20 bits for TIMx_ARR for timers 3 and 4, below.However, both TIM3 and TIM4 are 16-bit timers, as shown below.The following experiment on STM32G4 hardware aligns with the 16-bit understanding. Write pattern 0x12345678 to TIM3_ARR.Read TIM3_ARR, result is 0x00005678. Result should be 0x00045678 if width was 20 bits.On STM32G4 series, for timers 3 and 4, is the width of TIMx_ARR 16 bits or 20 bits?   

Hi,I'm somewhat new to STM32. I need to use DMA to collect data from a tempreture sensor over I2C.My sensor is an Adafruit MCP 9600 and I'm using a Nucleo F446RE board. Following is the code I use. Can someone help as I've been stuck here for days without knowing what to do.  uint8_t TMP_ADDR = 0x65 << 1;uint8_t TMP_REG = 0x00;uint8_t TempReading[100]; void MCP9600_ReadTemperatureDMA(void){TempReading[0] = TMP_REG;if (HAL_I2C_Master_Transmit(&hi2c1, TMP_ADDR, TempReading, 1, HAL_MAX_DELAY) == HAL_OK) {if (HAL_I2C_Master_Receive_DMA(&hi2c1, TMP_ADDR, TempReading, sizeof(TempReading)) == HAL_OK) {HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_SET);}}}// I2C DMA Transfer Complete Callbackvoid HAL_I2C_MemRxCpltCallback(I2C_HandleTypeDef *hi2c){HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_RESET);}

Heyho,and one more problem with my custom board with a STM32H733ZGT6 (LQFP-144, almost same as H723 on Nucleo).I'm using TIM5 for input capture, with CH1 (GPIO A0) and ETR (A4) as external clock input.The setup code is the same as on H723-Nucleo and H735-Disco, although I'm using another input capture channel, on these boards all is working fine.Problem:the 50 MHz input clock on ETR drops to < 2Vpp at the STM32 pin.Clock signal comes from VCO with 3.3Vpp, has 33R at output, and the ETR pin also has a 33R serial resistor.Voltage drops at each resistor.The same clock signal is routed to other IOs, also via 33R, no voltage drop there.All connections and resistor values checked and okay.Here's the timer setup, same as on working ST boards:void TimVcoSyncInit(void) { GPIO_InitTypeDef GPIO_InitStruct = { 0 }; /* set handle and pointer * ### THIS depends on used TIMx ### * eTAS8: TIM5 */ __HAL_RCC_TIM5_CLK_ENABLE(); pTimVcoSync = TIM5; hTim5.Instance = pTimVcoSync;

I want to build my stm32cubeide code from CLI, and thought STM32CubeCLI https://www.st.com/en/development-tools/stm32cubeclt.html#documentation would be useful. However, its user manual https://www.st.com/resource/en/user_manual/um3088-stm32cube-commandline-toolset-quick-start-guide-stmicroelectronics.pdf only provides some simple examples in the case of Windows.Does anyone know the information about the usage of STM32CubeCLI?

Hello, I am trying to develop an application capable of communicating with the STR3911B-Disco discovery kit. To do this I have downloaded the ST25SDK001 software and its API. I'm developing my application in C++ on QT creator, the final goal is to create a library that can interface with the kit. I'm making this library to embed it but I'm unable to find the serial commands to send. ST25SDK001 is developed in Java and not in C. Is there a way of finding the sources and commands for the lower layer, or are they protected? Thanks in advance.Regards,MelDubs.

hello expert:I encountered a problem when using the ST25R3916B evaluation board. The GUI displays 'not connected', but I have already entered USB mode using the blue button and reset button, and JP14 is in the normal state. The Micro USB and miniUSB are also connected.How can I connect it with GUI？ Is there any mistake in the above operation steps?

I am using an STM32 G474RE NUCLEO board. Is it necessary for me to configure the BOOT0 pin and the BOOT bits in the FLASH_OPTR register if I am going to program the chip using the SWDIO and SWCLK pins with an ST-LINK V2?

the chip of ST is different from traditional manufacturers that use circular dot or gap to distinguish the first pin of the IC. I cannot find the information in datasheet or the topics. Anyone can give me some information? thanks very much

I am currently working on repairing a Taramps MD3000.1 car amplifier. There is an ST chip with the following markings: 319MZLBD38 or it could be MZLB038.I'm not sure what it is and am having quite a time finding that out. I appreciate any feedback!

I am using STM32L0 with LSE rtc xtal, CubeMX/HAL. I have a 20 second wakup using  if (HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 40960, RTC_WAKEUPCLOCK_RTCCLK_DIV16) != HAL_OK) { Error_Handler(); } AND HAL_SuspendTick(); HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI); HAL_ResumeTick();  this works ok as long as I don't use //HAL_PWR_DisableBkUpAccess(); or it never enters stop modenow I use HAL_PWR_EnterSTANDBYMode(); to shutdown the device but it wakes 20 seconds later.so I tried adding  if (HAL_RTCEx_DeactivateWakeUpTimer(&hrtc) != HAL_OK) { ErrorHandler(ERR_ALARM_DEACT); }   but the call returns HAL_RTC_STATE_TIMEOUT Any ideas?

Hello everyone,I decided to write on this forum after encountering a problem with the implementation of ZigBee on my STM32WB55 microcontroller. Currently, the board connects to the network and sends the first data, but nothing happens afterwards.I am using the LAUNCHXL-CC1352P as the RCP which is connected to my computer and I run the Zigbee2MQTT 1.37.0 process. I'm using the same configuration for the Zlinky module and everything works fine, so I assume that part of the receiver works.As far as the FW is concerned, I would like to use the RTC to set a measurement task and send data every 30 seconds (for the moment). On the other hand, I have used some examples on ST's GitHub, in particular for the SED configuration. After some tests with LEDs, I can confirm that the RTC is working correctly.I have the impression that each new task configuration is ignored but I don't know why and the debbug mode do not help me at all.Thank you in advance for your help.Here is HAL_RTC_AlarmAEventCallba

Hi everyone. I am working on STM32G0B0 MCU and develop UI with touchGFX. I researched how to generate external loader for external NOR FLASH(MX25L6433F). I use SPI2 on MCU(SMT32G0B0). And edited relevant files. I applied all of steps on following links:https://blog.embeddedexpert.io/?p=2189Like W25Q FLASH Memory || Part 9 || External Loader in SPI Mode (youtube.com)Like External loaders for SPI flash: a "standard" version (youtube.com)I separately tested it. But xxx.stldr file is not working. STM32CubeProgrammer is unknown my STLDR file. I build without any problem. I checked that makefile under debug folder. There is an error that: fail-specified-linker-script-missing: @echo 'Error: Cannot find the specified linker script. Check the linker settings in the build configuration.' @exit 2 warn-no-linker-script-specified: @echo 'Warning: No linker script specified.

Hello,I am trying to use DCMI to connect the camera and display the video on LCD by LTDC. But it seems to me STM32CubeIDE does not allow me to active both DCMI and LTDC at the same time, because PA6 pin conflicts. And it seems the PA6 cannot be mapped to any other pin under DCMI and LTDC on the board Nucleo-H743ZI2. Does anyone have the same experience? How to use DCMI and LTDC at the same time? If the ST new released board does not have this conflict issue? thx.

stm32f429 ran in PCLK2 with 160MHz, and TIM8 prescaler division set to 0, auto reload set to 1.set up interrupt enable.in TIM8 update interrupt handler, just toggle PD4 pin out.when use oscilloscope to check the wave of PD4, just get around 2.3MHz. Can TIM8 generate 10MHz PWM with PD4 ?

This is a part of the circuit diagram of NUCLEO-F429ZI.What do the symbols in the picture below mean? is the inductance ohm value?thank you. 

Hi,I am trying to use CC1 and CC3 inputs on TIM2 of STM32H7A3 to do some time-critial tasks (very ns fast time-stamping). I need to identify which CCxIF tiggered. Using STMCUBEIDE the skeleton interupt code worked fine in debug mode without the lines comented with //WAIT. The countersTrigger_events_1 and Trigger_events_2 incremented as intended. In Run mode the code did not identify which flag inthe status register was set and did not count the interrupts. Adding the //WAIT lines waits (with a timeout) till one or both of the CCxIF flags in TIM2 status register is set. While this workaround works in the skeleton code, it will decrease time dependancy which is important for my application. In the reference manual it states:"If channel CC1 is configured as input: this bit is set when counter value has been capturedin TIMx_CCR1 register (an edge has been detected on IC1, as per the edge sensitivitydefined with the CC1P and CC1NP bits setting, in TIMx_CCER)."I am surprised that t
