Hi I hove something trobels with writing data after erease. I have only option bank and page erease and nothing other. I doing a bank1 erease and after this tryuing to write something whith is complitly not writing to memeory. Only on another compilation if memory is eresed I have data writen. How to clean and then write data? Im writing a uint16_t like a doble word, also I have only duble word. This making me cry, plese help just make a data rewrite, like it should be. I not wish have additional function for erease. Many thanks.#define FLASH_START_ADDRESS 0x08010000   // Function to erase the flash memory void erase_flash() { // Unlock the flash memory for writing HAL_FLASH_Unlock();   // Initialize the erase configuration structure FLASH_EraseInitTypeDef erase_init; erase_init.TypeErase = FLASH_TYPEERASE_MASSERASE; // Mass erase the flash memory erase_init.Banks = FLASH_BANK_1; // Select the bank of the flash memory to erase   // Perform the erase operation and

STM32F103:I see in the SPI configuration only prescalers of powers of 2. How can I adjust a distinct clockrate for SPI?

Good morning everyone,I'm using NUCLEO-WL55jc1 board and STM32CubeIDE 1.10.1. The case is that before creating a new second project, the ST-LINK V3 was detected and everything worked properly. However, currenly, when I want to debug the program I get this message (even with the first project I have, LoRaWAN_End_Node example).I hope someone could help me.Thank you very much,Carlos

Dear ST hello,I have a question about the bit field,I am using the stm32F429 discovery board, and I am working on the gyroscope Mems.if I declare a union like this:typedef volatile union { uint8_t All; struct { uint8_t Yen:1; /*X axis enable*/ uint8_t Xen:1; /*Y axis enable*/ uint8_t Zen:1; /*Z axis enable*/ uint8_t PD:1; /*Power-down mode enable*/ uint8_t BW0:1; uint8_t BW1:1; /*Bandwidth selection*/ uint8_t DR0:1; uint8_t DR1:1; /*Output data rate selection*/ } RegBits;   } Tst_CTRL_REG1;How does the compile organize the bits in memory?Does the MSB is Yen or DR1?Thank you in advance,

hello ST community,I am currently working on an application and I am developping the project on my board. In my application I am using a Micron NOR memory MT25QL512A in QUADSPI mode. I have previously used other OCTOSPI memories but the first time with Micron type. I have started the configuration but I think that may be I need some help that I also want to execute the code from the micron memory, any hints please?thank you.

Hi all,I am working with the STEVAL-SPIN3201 development board for controlling a BLDC motor. This board is based in the STSPIN32F0 controller which integrates the STM32F031C6 MCU. I attach the system-in-package block diagram taken from the datasheet.I am currently in the PWM generation stage (TIM1 for the U, V, W phases), but I cannot make it work. However, when I try to use other GPIO pins in the board (e.g., TIM1_CH1N in PA7 that comes directly from the F031C6 MCU) it works (as PWM, normal I/O, etc.). I don't know if the control logic in the block diagram needs a specific type of treatment but I have no clue how to deal with it, as there is no additional information and following the F0x1 reference manual doesn't seem to help. Does anybody have any clue? It would be very helpful. Thank you in advance.P.S. I've tried to use the motor control workbench but the only available code is based on PMSM motors and it's rather confusing.

My Settings : STM32G070 mit BootLoader protocol version: 3.1STM32CubeProgrammer v2.13.0My plan : flash my file via UART(USART2) and my MCU should start automatically after programming is finished. I will reset the nBOOT0 bit in my programm, after my own evaluation.My result :I tried with "Run after programming" in CubeProgrammer and "Go 0x800000" in STM32_Programmer_CLI. In both case, downloading was successfull but MCU could not start. See attached log file : logCP_uart.logStep 1 : nBOOT0 = 0, nBOOT1 = 1, nBOOT_SEL = 1 : this combination by Stm32G070 leads to boot from System memory (Bootloader)Step 2 : I could access boot loader via uart (com16) and start programming.Step 3 : My Transmitter.elf file was downloaded (line 32) and the Verifying was also successfully (line 36).Step 4 : But the RUNNING Program from Address 0x08000000 (line 37 and 38) could not be executed. Error Message : Error: GETID command not acknowledged! (line 44)See attached log file : logCP_CLI.txtLog fi

I am having trouble figuring out this seemingly simple thing. Assuming I have the coordinates of a touch point in a touch screen, how do I draw pixel to that location?

Hi, I am quite new to NFC reader, I want to know if it is possible to read multiple TAGs simultaneously with one board?i have ST25R3911B-DISCO board and bunch of 14443A Tag.if it is possible, what is the correct way to do the action??

Hello,is there a difference in declaring a C function with the __INLINE resp. inline keyword or using __attribute__((always_inline)) besides the latter one generating a warning?regards Herbert

I have a custom board with STM32H725IG using a multiplexed Octo SPI memory S71KL256xx. I have managed to establish reasonable communication to the memory thanks to example given in AN5050 even tough it was not H7. Sometimes, however, there are read/write errors and I suspect my PCB is poor. A new PCB will come soon.In the meanwhile, I am struggling writing a custom external loader. I have used the H7-example from stm32-external-loader/Loader_Files at contrib · STMicroelectronics/stm32-external-loader (github.com).I am using the same linker script given from the link, but in the Init() function in Loader_Src.c, the MX_OCTOSPI1_Init() hangs...int Init() { // Inits taken from Github example // https://github.com/STMicroelectronics/stm32-external-loader/blob/contrib/Loader_Files/H7%20device/Loader_Src.c *(uint32_t*)0xE000EDF0 = 0xA05F0000; //enable interrupts in debug SystemInit(); // called in system_stmh7xx.c   /* ADAPTATION TO THE DEVICE * change VTOR setting for H7 device

I've been trying for hours to read an analog value from a pin and write it over UART with no success on my STM32MP1. I've assigned PF14 to ADC2_INN2 and set IN2 to "IN2 Differential", then I generate the code and when I try to build I get a bunch of errors with regards to HAL functions.   I have "#define HAL_ADC_MODULE_ENABLED" in my stm32mp1xx_hal_conf.h, which I thought would be what I needed.

Heyho,I don't get the FDCAN on a STM32H735g-DK working with 8 Mbit/s.I feed the FDCANs with 80 MHz so that the "time quantum" is 12.5 ns to make 8 Mbit possible with the integers.I use the recommended kvaser website for calculations:https://www.kvaser.com/support/calculators/can-fd-bit-timing-calculator/#/canfd/* clock / timing */   /* nominal = arbitration phase * NBTP * 80 MHz: tq = NominalPrescaler x (1/fdcan_ker_ck) * -> tq = 12.5 ns * data rate = 1 / ((SyncSeg + Seg1 + Seg2) * tq) * with SyncSeg = 1 * 0.5 Mbps = 160 * tq * -> TimeSeg1 + TimeSeg2 = 159 */ phCan->Init.NominalPrescaler = 1; /* tq = NominalPrescaler x (1/fdcan_ker_ck) */ #if( 1 ) /* 5000 ppm */ phCan->Init.NominalTimeSeg1 = 138; /* NTSEG1 1..256, NominalTimeSeg1 = Propagation_segment + Phase_segment_1 */ phCan->Init.NominalTimeSeg2 = 21; /* NTSEG2 1..128 */ phCan->Init.NominalSyncJumpWidth = 20; /* NSJW 1..128 should be < NTSEG2 */ #else /* 500 ppm */ phCan->Init.Nomin

I am using STM32H7xx MCU with External QSPI Flash and SDRAM.I want to download my code using STMCubeIDE directly to External QSPI Flash and once done I want to execute the same code from SDRAM without compromising the debugging ability using STMCubeIDE. Can someone help me with some procedure here.

I have a simple repeat button that increments a value as you hold it in. However, I would like to change the repeat button on release so that the next time it is held in, it decrements the value.I'm new to object orientated programming as well so a complete answer will be highly appreciated. Thanks

Hi,I want to switch a project in cubemx from stm32f407 to the stm32h753. (both lqfp100in cubeMX 6.8.0 there is this pinout feature to show compatible cpus. cubeMX lists me all the variants of the stm32F4, L4 and F7 but there are no H7 listed.Is there a reason for that i'm missing?or is there another way to change my cubemx project to h7?regards

Hello! I'm trying to power only the mcu on a nucleo-L152RE dev-kit from the X-nucleo-LPM01A to measure it's power consumption, however i suspect the mcu is not running, and debugging it provides wierd results that I cant make sense of.   The program I'm trying to run is as simple as it gets: the onboard LED toggles on and off with a delay of 3000 ms. When powering the board from USB (debugger & mcu powered), everything works fine.   The issue arise when I try to disable the debugger and only power the mcu from the X-nucleo. I do this by connecting CN14 pin 1 (GND) and CN14 pin 3 (VOUT (+)) on the X-nucleo to GND and VDD (pin on JP6, IDD) on the dev-kit, respectively. In this configuration, the x-nucleo report a current draw of about 1mA, however the LED is not blinking.   I've followed the exact steps in the community post explaining this ("How to connect my stm32 to the x-nucleo-lpm01a"), read the user manual for the X-nucleo (UM2243) and nucleo-L152RE (UM1724) thor

Dear all,How can we generate a 40 KHz signal based on LSE (32KHz crystal)? If I Feed the HSE 32MHz / 32 to run the either LPTIMER's would it be still in low power?Thanks,mmsya.

Hello,I'm working with:STM32CubeMX version 6.8 (last version)STM32F4 FW version 1.27.1 (last version again)And, when generating a project with FreeRTOS, the FreeRTOS version is 10.3.1This version has been released more than 3 years ago!! It is completely out of date. Who would start working on a 3 years old version when there is an LTS version few months ago?? The current LTS version is 10.5.1!!It seems that this problem is caused by the (very very) long ST CMSIS development delay.CMSIS that is not so convenient:lake of some of the functionsNot so much support compare to FreeRTOS forumSo, what about the possibility for CubeMX to generate FreeRTOS code, without CMSIS, and with the LAST VERSION of FreeRTOS?Thank youAntoine
