Solved

I am having a problem with the USART on my STM32WL55JC2. I have configured the USART correctly, and I am using the correct pins, but the USART is not working.I have tried the following to troubleshoot the problem:I have checked the configuration of the USART using the STM32CubeMX software.I have checked the pins that I am using for the USART.I have used a logic analyzer to see if the USART is sending and receiving data.I have not been able to identify the problem, and I am hoping that you can help me.Here is some information about my setup:I am using the STM32WL55JC2 evaluation board.I am using the STM32CubeMX software to configure the USART.I am using a logic analyzer to troubleshoot the problem.

Hello,I am in process of designing my own STM32MP1 powered device. I was wondering if I can use STLINK-V3MODS as a drop in replacement for ST-LINK/V2-1 in STM32MP157-EVAL reference design. I need the Virtual COM interface embedded in device.-Mark

Hello,I am using a LSM6DSO32 on a custom board.  As an attempt to save power in sleep mode we want to place the device in ULP (ultra low power mode) as specified by the datasheet.  I have attached my function that initializes the device in ULP mode and enables wake up interrupt.  I see the same power draw wether or notctrl5.xl_ulp_mode is set.  Can anyone advise what I am doing wrong. Thanks!-Jamie

I am reading the  "Getting started with STM32U5 MCU" guie, which mentions that JTAG/SWD lines should have a 47-Ohms resistor and a 6.1V diode for ESD protection,.I am using s STLINK-V3SET to program a custom board. STLINK already includes these componentes for ESD protection.When design my custom PCB, I should follow the guidelines in "Getting started with STM32U5 MCU", and add additional diodes and resistor? Or it is not necessary because such components are already present on STLINK?I will connect the STLINK and the custom PCB using a STDC14 connector.      

I needed a help how to implement shutdown mode and wakeup from external reset in my application   while (1) { HAL_Delay(100); // MAINS INPUT Adc_Mains(); HAL_ADC_Start(&hadc1); HAL_ADC_PollForConversion(&hadc1,1000); Mains=HAL_ADC_GetValue(&hadc1); Hands=Hands*2/4095; HAL_ADC_Stop(&hadc1); HAL_Delay(100); //Battery operation Adc_Vbat(); HAL_ADC_Start(&hadc1); HAL_ADC_PollForConversion(&hadc1,1000); Vbat=HAL_ADC_GetValue(&hadc1); Vbat=Vbat*2/4095; HAL_ADC_Stop(&hadc1); HAL_Delay(100); //OPEN CIRCUIT DETECT Adc_OCD(); HAL_ADC_Start(&hadc1); HAL_ADC_PollForConversion(&hadc1,1000); OCD=HAL_ADC_GetValue(&hadc1); OCD=OCD*2/4095; HAL_ADC_Stop(&hadc1); HAL_Delay(100); //BATTERY TEMPARATURE Adc_Temp(); HAL_ADC_Start(&hadc1); HAL_ADC_PollForConversion(&hadc1,1000); Temp=HAL_ADC_GetValue(&hadc1);

Hello,I am trying to put my STM32F103C8T8 in sleep mode where all clocks are running etc. and wake it up using external UART interrupt.I am using MikroC as an environment and I don't think they have Wait for interrupt function. Is there any other solution to solve this? Is it too much of the work to set up registers, in that case do anybody knows which registers should I tackle?Thanks in advance!Best regards,Uros M.

I purchased a  P-NUCLEO-53L5A1 kit and successfully used it to collect data for depth estimation with the help of Quick start guide. But I have noticed that if I used STSW-IMG024, GUI for L5, to get collected data, I would receive a .csv document and it is shown like this:As I know, from some papers that describe principle of TOF sensors, raw data collected by L5 can be arranged as a HISTOGRAM with 100 bins. So how can I get this HISTOGRAM data (or depth data of each bin) but not just a sigma and median from a fitted normal distribution? 

Hello everyone. I installed STM32CUBEMX and STM32CUBEIDE on my Windows 11 and use them so as to get updates from STM32CUBEIDE but I can not update STM32CUBEMX : on the home page of CUBEMX when I click on "CHECK UPDATES" opens the window "Check Updates Manager" but when I click on the available version (MX.6.9.1) is not selected so I can not press the "Install" button but only "Update" or "Close.I already had this situation for the previous version (6.9.0).Thank you for your help in advancePs.

Hello Team,I have imported the Flash_EraseProgram from the github about nucleo-L412RB:https://github.com/STMicroelectronics/STM32CubeL4/blob/master/Projects/NUCLEO-L412RB-P/Examples/FLASH I have modified the code, in order to store 6 double values at flash memory and also Ι have created a simple function that read the values from the memory.When the values are uint64_t without fractional part I can write the memory successfully(MemoryPrograamStatus ==0) and I can read them correctly.When I try to store double words with fractional part, MemoryProgramSatus isn't 0, which means that the memory is not be writed correctly, and also I cannnot read back the values correctly.I attach the code and what I can see at the memory and the buffers.Thanks in advance. 

Hi everyone !  I am new to the ST Community, so please forgive me in advance if my request lacks clarity or information. I am facing an issue: I want to store a data in my memory that will be updated approximately every second or a bit more, that will be determined later. To achieve this, I am using the following function:void WriteDataToFlash(uint32_t data) { HAL_FLASH_Unlock(); FLASH_Erase_Sector(FLASH_SECTOR_7, VOLTAGE_RANGE_3); HAL_FLASH_Program(FLASH_TYPEPROGRAM_WORD, FLASH_USER_START_ADDR, data); HAL_FLASH_Lock(); }It works very well, my values change as I want them to. However, the problem I am encountering is that when I turn off my board and turn it back on, or even when I debug it, my memory seems to reset, even though I don't have a function that would cause my memory to reset. I believe there's something I'm missing, and since I'm new to working with memories, I'm having trouble identifying my mistake. Just to let you know, I am coding on an STM32F439VIT6

hi all, I don't know if I'm going off topic. But we don't get any news about this processor from the official distributors. Our company has developed a new project using this processor. The problem is that it cannot be found at official distributors and there is no certain information on which it will be available. which one can't be found? What are the times to be able to find it? Isn't it that it will be decommissioned? thanks in advance I don't know if I'm going off topic. But we don't get any news about this processor from the official distributors.

Hello my friends, why is not generated setup from CubeMx for my Keil, why is distinguish setup ?

I would like to display the received SPI data on a scroll list container from TouchGFX. But the thing is, data are coming in at high rate, around 10,000 times in a second and each of these data need to be display on reach row of the table.Is there a way to make an infinitely long table in Touchgfx? And also how do I make the table scrolls down automatically as data are coming?

Hi, I want to transfer 64kByte of data from memory to my display controller using SPI and DMA.Everything is working smoothly so far, but I have some problems of understanding, when I try to use the max. number of bytes.So: 64kByte = 65536 Bytes.But the SPI_CR2 Register ist 16bit, so takes only 65535 as Maximum number.Also the RM states for the DMA:"The amount of data to be transferred (up to 65535) is programmable and related to thesource..."The HAL function is also taking a uint16_t for the sizeHAL_StatusTypeDef HAL_SPI_Transmit_DMA(SPI_HandleTypeDef *hspi, const uint8_t *pData, uint16_t Size)and treats a size of 0 as an error.So it looks like the number of bytes that can be transferred is 1.. 65535, wich is in fact 64kByte -1 Byte.That means I cannot send my memory buffer with full 64kByte in one transfer.Any hint on how to set this up to transfer 65536 bytes would be appreciated, or the info confirmation, that this is not possible.Stefan

Hi,I have a situation where I can successfully program the target using STM32CubeProgrammer, but it fails when I try to do the same with STM32_Programmer_CLI.exe with an error:Error: failed to erase memoryBoth are v2.13.0.The command line I used:STM32_Programmer_CLI.exe -c port=SWD -d "firmware.bin" 0x08000000 -vb 3Attached are the verbose level 3 output from each. I am attempting to figure out why STM32CubeIDE fails to download code for debug. It also encounters the same failed to erase memory error. Appreciate any help anyone can give me. Thanks.

Hello,I'm working with ST25R3911B and in my application i want to control the field strengh.I relied on the documentation at this chapter : 1.3.40 RFO normal level definition register page 80 in the Datasheet - ST25R3911B - High performance HF reader / NFC initiator with 1.4 W supporting VHBR and AATAnd, if i understand well if i write 0x00 in the 0x27 register it will enable all Ohms segments, it will make 510 ohms.If i write 0x01 510-256=254 right ?But when I test my application with a field detectorit it doesn't seem to react as expected. Am I doing something wrong ?Best regards,Yvan

no response interrupt keep on triggering continuously after some time. please help in knowing the reason for this scenario.st25r3911b ic we are using and tag we are using st25tv 

Hi Everyone, Below Linux driver for LSM6DSL device has no method to read the temperature sensor. https://elixir.bootlin.com/linux/latest/source/drivers/iio/imu/st_lsm6dsxIs there a complete Linux driver which reads the temperature as well?thanks,   

Hi ,I am using HRTIM of STM32G4 (up-down mode, Complementary PWM).I am confused by what the reference manulal says.In RM0440 Rev 7 p.874,  the compare values is limited to within 3 periods of the fHRTIM clock below the period value.However, the compare value is limited to within 6 periods in the example.・Prescaling ratio is 32 at CKPSC=0・0xC0/32 = 6Which limit is correct, 3 or 6 periods?

Hi,I am trying to port the rfal library for an ST25R3916. I have defined all mandatory pins, ports and interfaces which RFAL requires in the help documentation.I have read that  ST25R_SELFTEST and ST25R_SELFTEST_TIMER are a good way to find the issues with the integration of RFAL library to my project.When I enable the above flags, I can see that the ST25R_SELFTEST is passed correctly without any error, but for ST25R_SELFTEST_TIMER it fails in st25r3916WaitForInterruptsTimed function:   /****************************************************************************** * Check SW timer operation : * - use the General Purpose timer to measure an amount of time * - test whether an interrupt is seen when less time was given * - test whether an interrupt is seen when sufficient time was given */ st25r3916EnableInterrupts( ST25R3916_IRQ_MASK_GPE ); st25r3916SetStartGPTimer( (uint16_t)ST25R3916_TEST_TMR_TOUT_8FC, ST25R3916_REG_TIMER_EMV_CONTROL_gptc_no_trigger); uin

Hello everyone,I have designed a custom PCB with STM32WB15CC. I am using two sensors (VL53L1X and MPU6050). I am using CR2032 coin cell as a supply and I have big problems with the battery management. The project example is using sequencer and what I want to do is to take a single shot measurement with the VL53L1X sensor and then put the device to sleep until a wakeup command is received via bluetooth characteristics. What is the best way to implement this behavior when using sequencer? The program behaves as expected when testing on NUCLEO-WB15CC. I first initialize the sensors and then use timer to trigger a function which returns accelerometer values. Then I check if I receive desired threshold values to call VL53L1X measurement. This is implemented in p2p_server_app.c. I would like to call the most convenient function to save power while keeping bluetooth connection alive since I want to wake up the device and do the same steps again when I send a command. Please see atta

Hello, after selecting the .elf file I get hundred of messages of this type:GDB Cmd [print /x & arm_cfft_sR_f32_len128.pTwiddle] failedError: Address of symbol "arm_cfft_sR_f32_len128" is unknownand similar, all related to CMSIS.After I ack all of these errors the import restarts with the same errors, only way out is by killing the program via process manager.All OK when variable addresses taken from .map are inserted, big pain but OK.What can be done?I'm aware of STMCubeMonitor, tried it but it looks like it's a joke, or at least not what I need. I just need a scope and a table to read and write variables. AFAIK CubeMonitor does not even have vertical scale adjust, just to mention the first showstopper.I'm shure that 99% of people share my needs. BTW STMCubeMonitor could conveniently be replaced with a binding to Python or whatever, then everybody chooses his own gui, framework etc.

Hi there,I would appreciate support in CubeMX for FreeRTOS for STM32U5-series. Currently I cannot find out how to configure this via the tool.FreeRTOS.org recently released a demo for IoT Reference Integration, running on an STM32U5. My old code is written and tested for using FreeRTOS, now we have to use the STM32U5-series, because older µC-series were not available.Is the porting already planned and if yes, when do you plan the release?Thanks for your answer ind advance.Best regards,K.

Hi,I have a problem after jump from application to my custom Bootloader.This the micro code: STM32G071KBU3.I correctly jump from application to Bootloader, but after the jump I don't get anymore interrupt from tick.I add an information: if I run directly the Bootloader from debug I correctly get interrupt from tick.Here the code I use for the jump. static void JumpToBootloader(void){uint32_t jumpAddr;void        (*jumpFunc)(void); /* si imposta il puntatore a funzione utilizzato per il jump */jumpAddr = *(__IO uint32_t*) (BOOTL_START_ADDR + 4);jumpFunc = (void (*)(void)) jumpAddr;     /* Initialize user application's Stack Pointer */    __set_MSP((*(__IO uint32_t*) BOOTL_START_ADDR )); // si salta al Bootloader    jumpFunc();}
