I am using the B-L072Z-LRWAN1 and trying to code LPTIM with interrupts and no HAL. The code seems to be getting stuck in the Infinite_Loop section in the startup.s file. The comments around this loop say that an unexpected interrupt was triggered. If I remove the NVIC functions in lptim_init(), the controller does not get stuck anymore. I have tried:-setting the IER register to 127 (all interrupt sources enabled) with a breakpoint on the lptimer IRQ handler. The handler is never called.-declared & defined all possible IRQ_Handler functions in stm32l0xx_it.c with a while(1) inside each one, and watched all of them with breakpoints. nothing.-putting the NVIC functions before or after setting the IER register. no change.here is my code for the lptimer: void lptim_init(LPTIM_TypeDef *LPTIM, lpTimerMode mode) { uint32_t tmpcfg = 0; uint16_t tmpier = 0; //enale the oscillator for the peripheral __HAL_RCC_LPTIM1_CLK_ENABLE(); //encoder mode disabled tmpcfg &= ~LPTIM_CFGR_

I am developing a PCB using the ST25B02k component, but I miss the info to generate the correct footprint (die form named SBN12). Can you help me get the chip measurements and drawings? Thank you so much. 

Hi,I have a question regarding the implementation of the Qt framework for the STM32H747I-DISCO board. While browsing the Qt website, I noticed an example for the similar STM32H750B-DK board, but I couldn’t find any information specific to the DISCO model. So my question is: will the Qt implementation for the 750B board be compatible with the 747 board? Will it be possible to run the sample applications on both boards without any modifications?I have another question. From what I understand, it is necessary to use a bootloader (due to the small flash memory). Is it possible to access the bootloader code through STM32Cube/gitrepo? And will it be available for the 747 board? (I saw that a HEX file is uploaded on the website.)Thank you in advance for your response.Rafał

Hi, I wanted to know is it possible to use QT designer (with stm32h735g-dk) for GUI instead of TouchGFX.Thanks,

Hello,I'm using STM32CubeH7 1.11.2 and STM32CubeIDE 1.12.1.The zip files available both on github and on st.com for STM32CubeH7 1.11.2 are not functional because many files are missing (not the same in both zip files b the way...). I guess this is because of the submodules in the git repository, I guess the zip generation did not include the submodules.Would be great to re-generate the zip files or remove the links for the zip files and let people download only through git. I have lost a lot ot time dealing with this.Regards

Hello everyone.Because I need to test a newly purchased SPC560-DISP, I tested several commonly used modulesAnd these is my test devices:Devices Used:MCU: SPC560P-DISPCAN: Kvaser Leaf LightV2I conducted tests on several commonly used modules:PITEIRQPWMADCThe test results for the above modules showed no issues. However, when testing the data transmission functionality of the CAN module:Loaded my own test program onto the development board.Kvaser and BUSMASTER were successfully connected.Yet, I couldn't observe any data in BUSMASTER.So, I replaced the SPC560P-DISP with another board of the same model that I had already and repeated the same steps in the same environment. Sadly, I could observe the values I intended to transmit in BUSMASTER.What settings might I have overlooked that could cause this abnormal behavior? Or could the development board might be damaged? ThanksLouie

I am using SPI to communicate between STM32H7B3I-DK (master) and Nucleo-H743ZI(Slave). My Data transmits as expected; however, after transmission the MISO and MOSI lines stay high. I have Master Keep IO State Enabled on both.I am not using HW NSS, and have setup my own NSS(nCS)SLAVE SPI:   hspi1.Instance = SPI1; hspi1.Init.Mode = SPI_MODE_SLAVE; hspi1.Init.Direction = SPI_DIRECTION_2LINES; hspi1.Init.DataSize = SPI_DATASIZE_8BIT; hspi1.Init.CLKPolarity = SPI_POLARITY_LOW; hspi1.Init.CLKPhase = SPI_PHASE_2EDGE; hspi1.Init.NSS = SPI_NSS_SOFT; hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB; hspi1.Init.TIMode = SPI_TIMODE_DISABLE; hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE; hspi1.Init.CRCPolynomial = 0x0; hspi1.Init.NSSPMode = SPI_NSS_PULSE_DISABLE; hspi1.Init.NSSPolarity = SPI_NSS_POLARITY_LOW; hspi1.Init.FifoThreshold = SPI_FIFO_THRESHOLD_01DATA; hspi1.Init.TxCRCInitializationPattern = SPI_CRC_INITIALIZATION_ALL_ZERO_PATTERN; hspi1.Init.RxCRCInitial

Hello, I am trying to receive and transmit byte-to-byte on a STM32F429 Discovery, I will be using a STM32U5 Discovery soon. I used UART IT method but maybe there is a better solution...Objective & Issue:I want to continuously receive and send byte-to-byte, goal is to apply a function to each byte before transmitting it. Right now I can receive and transmit but I lose some characters in the process.For example if I send "Passphrase" to Uart using a python script, my implementation will transmit something like "PasPhase". It gets worst if I add more code to do something to the byte for instance...How can I fix this ? This is not the case if I use a bigger buffer but I want to make sure I receive a byte, treat it and send it through UART ASAP, maybe there is a way to receive next byte at the same time I am treating the current byte ? What I did:I am using HAL_UART_Receive_IT and HAL_UART_Transmit_IT based on examples I found in the F4 firmware.I am using a tag UartReady to S

Hello. The following is machine-translated so it might seem a bit strange. I'd like to ask if I can use my only computer, the "MacBook Pro with M1 version", to connect to ST-LINK V2 to program the STM32 on a C8T6 chip's PCB board. I've tried using V1 before but without success. STM32CubeIDE couldn't recognize ST-LINK, and thus it wasn't able to program. I hope you can help me solve this problem. Thank you very much.

Hello,I'm working with SensorTile (STEVAL-STLKT01V1) and using the AI-SENSING1 firmware. I would like to replicate the energy saving behavior I observed in the ALLMEMS1 firmware: it goes into shutdown mode after a period of no connection and can be reactivated by a double tap event. In ALLMEMS1, this behavior happens automatically, but in AI-SENSING1, I am facing difficulties implementing this logic.My question is: what specific steps should I follow to replicate the behavior of ALLMEMS1 in AI-SENSING1, or is there any example of implementing this shutdown with wake-up via double tap for AI-SENSING1? I would also need guidance on how to configure the timer so that the shutdown occurs automatically after a pre-determined time without connection.Thanks in advance for any help or guidance.

Hi，I am now adapting the stm32mp13 bare metal bootloader FSBLA_Sdmmc1 for stm32mp157, and have achieved good results. However, since the sd card partition table of stm32mp13 is different from the common gpt partition table, the full function of this bootloader cannot be fully utilized. I guess it is due to the sd external loader. Therefore, I hereby apply to the STMicroelectronics support teams for the source code including the following content to adapt my subsequent content1.sd external loader2.emmc external loader3.snor external loaderThank you, the following is my github repository for storing the bootloader and program of mp15https://github.com/youngsea2000/STM32MP1xx_Baremetal

Dear All, I want to use STM32CubeMonitor to monitor 64-bit variables, such as int64_t or uint64_t. However, it seems that 64-bit variables cannot be selected from the variable list (they are not displayed).Is there any way to achieve this?Best Regards,Fan         

Hi there,There is a config option named "OB_STOP_RST" that exists in Option Bytes' USERconfig, I tested it with STOP mode, and it works well.But I can't understand when we should use it. After clearing this bit to OB_STOP_RST, the MCU will reset right away and enter run mode when it enters stop mode, why don't we just reset the MCU, it's easier and faster.Same as the OB_STDBY_RST config.

Hi all,I am trying to use the STM32H735G-DK as a Dashboard/Speedometer for a car project. However, I am having trouble integrating the FDCAN with the GUI. I have tried building the FDCAN code first then generating the GUI and vice versa.The Board is receiving CAN messages fine however it is not sending anything back, instead, the TxBuffer fills up and causes error 512. My colleague told me there is something to do with the interrupt timing and FreeRTOS, so I have tried polling and it still wouldn't work. my main way of testing is connecting the two FDCAN peripherals already on the board in normal mode and sending messages.I have uploaded my .ioc file and main.c any pointers and help would be much appreciated, thank you!

I started to use this stlink v3set since year 2023. All works well until recently it get offline and reconnected immediately sometimes. The red light flashes several times then stays on after connect to USB. The STLINK_V3S disk is opened in an explorer.The firmware for this programmer set is V3J15M7B5S1. I tried to downgrade it to V3J15M6B5S1 using CubePrg but with no luck.  Whenever downloading code in STM32CubeIDE, I get this error message:Error in initializing ST-LINK device.Reason: No device found on target.Anyone could help? ThanksBtw, I bought a J-link EDU to replace this malfunctioned stlink v3set just in case that it could be fixed.

Hi there,first of all: I'm a software engineer and working with electronics only as a hobbyist. Therefore expect *** errors :)I'm trying to use a ST25R3916B in my ESP32 project. The I2C communication to the ST25R3916B is working.The call to rfalNfcInitialize succeeds but the next call to rfalFieldOnAndStartGT causes the ESP32 to crash with a " Core 1 panic'ed (Interrupt wdt timeout on CPU1).". The interrupt is taking too long.Looking into the code, I found this function:  /*******************************************************************************/ void RfalRfST25R3916Class::st25r3916CheckForReceivedInterrupts(void) { uint8_t iregs[ST25R3916_INT_REGS_LEN]; uint32_t irqStatus; /* Initialize iregs */ irqStatus = ST25R3916_IRQ_MASK_NONE; ST_MEMSET(iregs, (int32_t)(ST25R3916_IRQ_MASK_ALL & 0xFFU), ST25R3916_INT_REGS_LEN); /* In case the IRQ is Edge (not Level) triggered read IRQs until done */ while (digitalRead(int_pin) == HIGH) { st25r3916ReadMultipleRegister

Hi there!First, I need to declare my frustration with CUBE IDE complexity. My code is not for blinking a LED or test one button, but a complex code that involves an 7 inch LCD, EEPROM, TEA6686 PLL, DS3231 RTC, DS18B20 temperature sensor and so on, It is almost impossible to organize the code with so many files to manage, and now, besides of working fine at main.c file, the I2C3 is not recognize outside the main.c file. This is boring, so boring that I am hard thinking to change the processor and IDE. Tons off #includes, tons off crisscross references, we get crazy...... What the hell…..Well, my code is to far advance, lets see how may I solve this problem…. It is the edge….I created a file R_T_C.c and RTC.h to manage all information regarding with DS3231, but when I try to use “HAL_I2C_Mem_Write(&hi2c3, 0XD0, 0X0E, 1, 0b00000000, 1, 1000);”  it says that  'hi2c3' undeclared (first use in this function). What may I do to solve the new issue…… Already tried to #include ever

We use VL53L1X for liquid level detection purposes.We believe that the “signal-rate” needs to be high in order to accurately detect the surface of the water at a distance.We are considering the VL53L1CB as a candidate.Is the VL53L1CB a good candidate?It is important that the VL53L1CB is software-compatible with the VL53L1X.Thank you. 飛行時間

I am using the Nucleo-H743ZI, with a SPI ISR I wrote originally on the STM32H7B3I-DK board. However, when I usevolatile uint8_t rxBuffer; volatile uint8_t txBuffer; *((__IO uint8_t *)&hspi->Instance->TXDR) = txBuffer; //or rxBuffer = *((__IO uint8_t *)&hspi->Instance->RXDR);I get a syntax error on the Nulceo. I checked the stm32h7xx_hal.c file and they use these two lines for the default SPI handler. I have stm32h7xx_hal.h included, but still have a syntax error... wondering if anyone knows what may be going wrong. I'm not sure why there is no error on my STM32H7B3I-DK board, but there is on the Nucleo.

hey thereI have a customized board with STM32F030K6T6 on it and a 11.0592MHz crystal for HSE. the thing is my code does not run through and when I try to debug it, I can see it sticks in SystemClock_Config(), more specifically, in HAL_RCC_OscConfig() and when I trace it even more I get to __HAL_RCC_HSE_CONFIG() which seems like is responsible for bit setting and stuff... any ways I have no Idea why this happens and though I think crystal is just fine(the reason is that I have tested my code in other boards and it was OK! therefore I dont think the problem is my code, it should be hardware somehow but I dont know what it could be?) HELP!

Questions:1. Does STM32H753 have three independent 16-bit SAR ADC modules?     Any other STM32 parts also have 16-bit SAR ADC modules?2. Can a selected channel in each 16-bit SAR ADC module (Totally 3 selected channel in the 3 modules) be sampled simultaneously under the same clock rate?3. How are the Direct /Fast /Slow channels in SAR ADC defined?4. Which STM32H753 is used in NUCLEO board? (VI, ZI, AI......)Thanks,Rong
