STM32 MCUs Products

Hi people,    I just work on a Dali project and trying to learn from the demo library I am getting some error can anyone PLEASE help me how to proceed.I am trying in STM32G0I am getting error as EXTI.Instruture undeclared i tried EXTI.Instruct but still its showing error  'NVIC_InitStructure' undeclared hOW CAN I DECLARE THAT FUNCTIONS  void receive_tick(void) { // Because of the structure of current amplifier, input has // to be negated actual_val = get_DALIIN(); tick_count++; // edge detected if(actual_val != former_val) { switch(bit_count) { case 0: if (tick_count > 2) { tick_count = 0; bit_count = 1; // start bit } break; case 17: // 1st stop bit if(tick_count > 6) // stop bit error, no edge should exist flag = ERR; break; default: // other bits if(tick_count > 6) { if(bit_count < 9) // store

I have a problem programmatically setting RDP to level 1.My code is:OBInit.RDPLevel = OB_RDP_LEVEL_1;OBInit.OptionType = OPTIONBYTE_RDP;ret = HAL_FLASH_Unlock();ret = HAL_FLASH_OB_Unlock();/* Clear SR register */CLEAR_BIT(FLASH->SR, FLASH_SR_BSY);ret = HAL_FLASHEx_OBProgram(&OBInit);ret = HAL_FLASH_OB_Lock();ret = HAL_FLASH_Lock();HAL_Delay(2000);ret = HAL_FLASH_OB_Launch();// shouldn't get to this point, as processor will resetI had to put in the clear pf FLASH->SR, otherwise the "FLASH_WaitForLastOperation" would fail inside "FLASH_OB_RDPConfig". I've no idea why the flash should be busy at this stage.Whether or not I run this under the debugger, the RDP byte never changes. The last HAL_Delay is to give the flash chance to be written properly before the launch resets the processor.

Hello,I struggle to use the LSE clock as a source for timer LPTIMER1. My MC is a STM32L051R8Tx and I am using Keil MDK-Lite. ARM Compiler default 5.For debugging purpose I am using the following settings: PSC = 1; ARR = 3275; Interrupt: Auto-reload match. In the IRQ handler I toggle a LED to measure the frequency by use of a manual stop-watch.I cant measure the 32,768 kHz. Instead I measure the following: with printf() statement in loopwith debuggerLowest drive~3,276kHzwith printf() statement in loopwithout debuggerLowest drive~3,276kHz    without printf()with debugger

Hello Every one I am using NUCLEO-G0B1RE board when trying to store the data in to flash memory address its not updating after erasing but individually if I try only erase or only write data in to flash memory it is working please suggest me below is my code at run time i would like to erase and update the data suggest me if went wrong in the codeuint32_t BaseAddr = 0x08041000; //global variable.uint64_t FlashData = 0xee;////global variable.inside main function HAL_FLASH_Unlock();FLASH_PageErase(2,258);HAL_FLASH_Lock();HAL_Delay(100);HAL_FLASH_Unlock();HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, BaseAddr, FlashData);HAL_FLASH_Lock();

HelloI have a code use CAN2 on a stm32F105 he work fine if the CAN bus have not disturbanceBut if i have to many disturbance for exemple if i make a short circuit bethen CANH and CANL when i remove the short circuit the CAN no restart to send data. I need stop and restart CAN  HAL_CAN_Stop(&hcan2);HAL_CAN_Start(&hcan2);Then he work but i lose data during this time during bug HAL_CAN_GetTxMailboxesFreeLevel(&hcan2) return 0hcan2.ErrorCode are equal to 0hcan2.Instance->TSR -> have the bit CAN_TSR_TERR0 set to 1 but if i call HAL_CAN_AbortTxRequest(&hcan2,CAN_TX_MAILBOX0);CAN_TSR_TERR0 return to 0 but CAN no restartCan you help me for have a CAN work every time?

问题描述：我电路板上使用的单片机是STM32H750系列，电路板工作正常; 始终使用STLINK工具下载程序; 最近，MCU经常出现无法下载程序的问题。具体现象是STLINK工具弹窗显示“读出保护已激活”。关闭弹窗后，出现“无法连接目标”消息，计算机与MCU失去连接。 我在网上搜索了很多解决方案，但没有一个能够解决它。最后，我不得不用新的MCU替换MCU。 更换后，它工作正常，下载程序没有问题，但下载几次后问题再次出现。我非常苦恼，

I have a B-G431B-ESC1 board connected to a 7-pole BLDC motor controlled for speed. I tried connecting the motor's Hall sensors and running it via MotorPilot 6.2.1, both with a 6-step algorithm and an FOC algorithm, both generated with Workbench 6.2.1 and compiled with STMCubeIde 1.14.0. It works.Then, I replaced the Hall sensors with a TLI5012BE1000 absolute encoder (A/B interface with 0-index). I did the wiring and checked with the oscilloscope that it was correct (A, B, and Z signals as per ST documentation). Through motor pilot, I can see that the speed value is being read. I used the tachometer in the GUI to verify that the rotation direction of the encoder was the same as the motor (the encoder is mounted on a development board and I can communicate with it via USB). I made sure that the steps per revolution matched between the encoder and the Workbench configuration.Unfortunately, the motor does not turn. From the oscilloscope, I see that all the motor phases PWM

The Debug Display： Startup Address is not 8000000，but 1FFFxxxx, I Have Checked The BootPin, ResetPin, And JlinkPin, All is Right.  Power is also Stable, Generally, when you appear to be awakened when Chip sleep, the appeal will appear. After downloading, the startup fails, and then I can't start it. Appeals have been appealed by 4 products.仿真显示：启动时候的地址不是8000000，而是1FFxxxx，我已经检查了启动脚，复位脚，jlink下载脚，都是正确的。电源也很稳定。同时，这个问题是偶发的，一般出现在休眠情况下要唤醒的瞬间下载程序，就会出现上诉情况，下载完启动失败，然后一直启动不了。已经由4款产品出现上诉同样问题。

Hi @everyoneIn the below IIC API HAL_StatusTypeDef HAL_I2C_Mem_Read(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint16_t MemAddress, uint16_t MemAddSize, uint8_t *pData, uint16_t Size, uint32_t Timeout)uint16_t MemAddress will accept only hexadecimal value or it will accept decimal value also.    

Hello ! I've been wondering, how UART works in receiving side ? I have like maybe 4/5 questions ? -> What if I have a RX buffer that is full ? The flag is on and I didn't read the data. Then the new data comes after sometime, will it overwrite my data and still the flag will be on ? -> Is the data in the RX buffer loaded bit after bit or is it loaded whole word (8 bits) in one go and not bit by bit ? -> How do I know when I type HAL_UART_Transmit and after that the peripheral will be sending data and after transmit command I have the command HAL_UART_Receive, so how do I know it was fast enough to read the whole data without loosing any new or old data ? Like it was to late although the commands were one after another.-> What if I used IT or DMA, they are non blocking, and questions like above like what if I type Transmit and Receive will I make it in time ? or what if I didn't read data and

Where can I get schematics for these 2 dev boards in pdf format.  I found a link to the cad resources but they do not contain pdf or any recognizable format. Thanks in advance for your help !!!

I am trying to setup my STM32H725 to use serial RAM in memory mapped mode. The memory I am using is:IS66WVS4M8ALL RAM DatasheetI have used IOC to setup the OCTOSPI1 as a QSPI peripheral and mapped CS IO0/1/2/3 CLK from the uC to the RAM.I have tried to firstly set the RAM for 4 pin access, then setup the cfg for read and write, finally enable the memory mapped mode. Though it does not work, in debug mode it typically crashes at some point.I have modified the init for Octospi accordingly: static void MX_OCTOSPI1_Init(void){ /* USER CODE BEGIN OCTOSPI1_Init 0 */ /* USER CODE END OCTOSPI1_Init 0 */ OSPIM_CfgTypeDef

Hello everyone.I'm interfacing my STM32F745IET6 (master) with an SPI device.I'm using SPI1 interface running at 50 MHz, I was wondering if there's some "rule of thumb" to calculate time needed (in terms of clock cycles) to write n bits over the bus. Thank you very much in advancedNick

Hello,I want to transfer data between NVIDIA Jetson Nano (Master) and STM32 (Slave) using SPI. On the master side, I am using spidev python library. On the slave side, I am coding using registers (without using HAL).I want to send and receive data continuously between the two systems. When I run the codes, the data are correct for the first few cycles. However, after some cycles, the data are right-shifted by one bit. It happens randomly after some cycles in a circular mode (after some shifting, the data will be correct for some cycles and then the shifting continue again and so on). What could be the issue that is causing this shifting? I want to make sure SPI is always transferring correct data continuously. Is it possible that there are some buffers that need to be cleared after each cycle?I am using SPI with interrupts. Here is my SPI configuration (spi_enable and disable just change the SPE bit): 

Hello,I am working with a STM32F446ZET6 and using it as an SPI slave.I use the function HAL_SPI_Transmit_Receive_IT function to receive 4 bytes of data.It used to work properly in our conception, for example when the master sends 0x12, 0x34, 0x56, 0x78, in my reception buffer on the slave side i receive correctly the data in this order.Recently, we received 10 new boards: on one of them the SPI is behaving strangely when the sending frequency is above 1000Hz. When the master send the same data as above, sometimes the STM32 receive them in disorder : meaning that in the reception buffer we may have 0x34, 0x56, 0x78, 0x12.When troubleshooting it appears the problem comes from the STM32 because when we replace it, the problem disappeared.But I don't understand this problem that appear with some chips. Is there a way to fix that with code?

Hi all,I'm facing a problem with the implementation of a double Own address on a STM32F030K6T6 uC. the project is already working but with only 1 Own address on OAR1 (code 42 hex), now I want to update the project to enable the reception of another code (52 hex) on OAR2 but there's something wrong on the matching address of the i2c hardware of ST I think, because it seem that hide OAR1 and made priority to OAR2. It is possible? Thnaks.

I have added a Touch screen library and I am unable to integrate it into Touchgfx Project that is opened inside Stm32IDE -I am getting File not found errorWhat I have done so far-Added the file using Properties ->c/c++ general-> path and symbols ->Includes (Added My Custom Folder GT911)But When I am adding the header under Sampletouch.c I am getting "target/STM32TouchController.cpp:24:10: fatal error: GT911/GT911.h: No such file or directory"But the file shows up using control + Click on Header file

Hi i m learning to configure GPIO using registers, and come across the following code, can anyone kindly help to advise the following? what does the whole sentence do? what does the (volatile....) means, what does GPIO_OUT_DATA(0) does and what does  + SOC_GPIO_0_REGS means?  #define GPIOSR_ADDR      (*(volatile unsigned int *)(GPIO_OUT_DATA(0) + SOC_GPIO_0_REGS))

Hi I've been searching for some info about these two MCUs and I need some clarifications.1. What is the difference between STM32U585RIT6 and STM32U585RIT6Q?2. On page 150 of DS13086, STM32U585xx datasheet, regarding power supply scheme, I can see the presence of VDDIO2 like below, But on LQFP64 pinout for STM32U585RIT6 doesn't have any VDDIO2 but three VDD pins.

Currently i am using USB peripheral for communication (CDC) with STM32F070CBT6 microcontroller. For generating 48MHz clock, i am using internal oscillator as a source for internal PLL circuit. I have to send certain data to STM32 (for save it to external EEPROM (on same PCB card on which STM32 is installed). The STM32 will then acknowledge it. Similarly, STM32 will send the data to PC when requested. So, data transfer is only request based. Practically, I have tested it several times and it is working.But, now i have read the line from STM32F070CBT6 datasheet regarding USB as "It requires a precise 48 MHz clock which can be generated from the internal main PLL (theclock source must use an HSE crystal oscillator)."My Question is:- What consequences can occur if i continue with the internal source?

Hi, I am trying to use DMA in my project for SPI and noticed there are 2 type definitions as below:-  SPI_HandleTypeDef hspi1; DMA_HandleTypeDef hdma_spi1_tx;  Which one do I need to use for SPI transmission as I am having problems using 'hspi1' as below:-  HAL_SPI_Transmit_DMA(&hspi1, "Test",sizeof"Test"); HAL_SPI_Transmit_DMA(&hdma_spi1_tx, "Test",sizeof"Test");   I just wasn't sure which handle was the correct to use...

Hi, Has anyone fed the Analog Watchdog Internal Signal output into Timer 1 on the STM32G031K6 ? To Drive Mosfet power switches of a Power Supply, The Analog Watchdog is used to limit the current. The timer 1 also has a break function and some fancy features designed to drive power switches. Any help/suggestions would be appreciated. Thanks.

Hiwhen the STM32F103 enter the standby mode, it has the lowest power consumption. And it said the voltage regulator is switched off. And all of the data in the RAM will be lost except the backup ram and register of the RTC.But I tested it, the data will still keep the value (the standby mode could be entered successfully that the consumption will be reduced to several micro-amperes). the different thing is that all the supplies are still supply to the MCU (not only the VBAT).So that means the LDO is not actually switched off as it doesn't detect VDD to be lost or lower than the threshold.Is it right?

Hı everyone, ı was trying to design basic timer project in register level about toggling on related led pin every 1 second. However, the led is on a few seconds after that it is off and never becoming on. When ı do the same project in HAL library, it worked well. By the way, I use APB1 as 84 MHz. Is there anything i missed out ?  /* Includes */ #include "stm32f4xx.h" #include "stm32f4_discovery.h" void RCC_Config() { RCC->CR |= 0x00030000; // HSEON and HSEONRDY enable while(!(RCC->CR & 0x00020000)); // HSEON Ready Flag wait RCC->CR |= 0x00080000; // CSS Enable RCC->CR |= 0x01000000; // PLL ON RCC->PLLCFGR |= 0x00400000; // PLL e HSE seçtik RCC->PLLCFGR |= 0x00000004; // PLL M = 4 RCC->PLLCFGR |= 0x00005A00; // Pll N = 168 RCC->PLLCFGR |= 0x00000000; // PLL p = 2 RCC->CFGR |= 0x00000000; // AHB Pre
