Hi Team,Can we interface AD9850 DDS Signal Generator Module with STM32F407G to generate sin wave and square wave, is there any procedure or links to interface between AD9850 with STM Microcontroller.Best RegardsGagan Gowda

What is shelf life of STM32F071VBT6TR MCU ? How long I can store it in my warehouse before assembling it on PCB ?

I am using STM32G431cbtx and enabling RCC_MCO. Since the STM32G4 supports two pins, PA8 and PG10, PA8 is being used for another function, and I am using PG10 for RCC_MCO. However, when measuring the voltage on pin PG10, it is always high. Can anyone explain it to me?

Dear engineers,I hope this message finds you well. I am currently encountering an issue with the internal connection feature from DAC to ADC in CubeMX. Specifically, I cannot locate the ADC2 IN16 in the interface, and upon setting up the IN17: VDAC1_OUT2 Channel, CubeMX continuously loads without completing the process.I have attempted to resolve this issue by using different versions of CubeMX, starting a new project, and even testing it on various computers, yet the problem persists. Could this be a bug in the software, or might I be missing a step in the setup process?Thank you for looking into this matter and for your ongoing support. 

Hi Folks,I'm having a problem with connecting my ST-Link/v2 to my new board with a STM32H7ARIT micro on it.I have had no problem connecting the ST-Link to another board with the STM32F103RBT6 micro on it. I have the Debugger configuration in the STM32CubeIDE set to:Autostart local GDB serverDebug probe - ST-LINK (ST-LINK GDB server)Interface - SWDST-LINK S/N: the scan finds the ST-LINK/v2Frequency = AutoAccess port: 0 - Cortex M7Reset behavior = Connect under resetThe error message I'm getting when I try to debug the program:Error in final launch sequence:Failed to execute MI command:target remote localhost:61234Is there something I've missed?Thanks,Richard

Hello,I sort of feel *** not to get sure there not a best solution. I develop an Audio board, with USB HS. I will have a good 49.152MHz clock to drive the SAI, and I wanted to ue it for the HSE.49.152 * 125 / 256 = 24MHz that I need for the ULPI. Looks good49.152 * 625 /2 = 480MHz, the max MCU freq. Looks goodI would prefer not use Fracn feature as the above seems to get it right (pure aestetic concern I believe).But the PLL DIVN1 is limited to 512 for the multiplication factor. So I find as best "solution" 49.152 * 500 /2 = 384MHz... Which wastes some MCU processing power.Is this the max MCU freq I can acheive while possibly generatind "pure" 24MHz for USB ULPI and not using Fracn? Is there a better solution?For learning purpose, is there an "algo" to allocate manually PLL  M-P-Q to achieve 1 target Freq on PLLQ and max SysCLK?Sure this is not a pragmatic concern, as Fracn feature allows for 480MHz Sysclk and 24MHz multip

Hello, for safety applications, are there any recommendations for tool chains from ST's side?

I want to control the intensity of 12 led's simultaneously. I purchased LED DRIVER 19 CLICK and STM32 Nucleo-L073RZ board. Please help me with the programing and interfacing.

Greetings! I'm experiencing strange behaviour when invalidating or enabling the DTCM-RAM on STM32H723 (using the Nucleo board for this). When debugging and using the step-over functionality, the invalidate and/or enabling process for the D cache seems very slow, taking at least over 30 seconds whereas if I just "run" the program in debugging mode and it runs normally. Is this something related to the stepping mode / ST-Link or is there something wrong with the MCU itself?This is what the variables inside the SCB_InvalidateDCache look like when stepping and I have confirmed that they look the same when running the code until some breakpoint.

i m using an stm 32 microcontroller to read adc channel, this is my approch: discontinuous DMA requests in Normal Mode and single conversion adc for multiple channels, i want the adc channels to be read 20 times in a row, with a frequency of 1Khz using Tim6, and be printed through USART2. when I give the order "sample" in the serial monitor, the tim6 is triggered, and start an stops the DMA and prints the values for 20 times. the Problem is, that i get values that make no sense, but they re the same every time, even when the microcontroller pins are not connected to different signals (from 0V to 3V) or to anything. Here is my code: ------------------------------------------------------------------------------1. in main.c-------------------------------------------------------------------------------static void MX_ADC1_Init(void){/* USER CODE BEGIN ADC1_Init 0 *//* USER CODE END ADC1_Init 0 */ADC_MultiModeTypeDef multimo

I made a board with spi1 connect a lora module, and the nss pin, I just want to use soft control. But I found that before I enable spi1, the SPI CR1 and CR2 register value as: (gdb) x/2wx 0x40013000 0x40013000: 0x00000024 0x00000040 but after I do spi_enable(SPI1), I get these register as below: (gdb) x/2wx 0x40013000 0x40013000: 0x00000020 0x00000040 This is the releate codes:  spi_init_master(controller, SPI_CR1_BAUDRATE_FPCLK_DIV_32, SPI_CR1_CPOL_CLK_TO_0_WHEN_IDLE, SPI_CR1_CPHA_CLK_TRANSITION_1, SPI_CR1_DFF_8BIT, SPI_CR1_MSBFIRST, SPI_NSS_SOFT); spi_enable_rx_buffer_not_empty_interrupt(controller); spi_enable(controller); int spi_init_master(uint32_t spi, uint32_t br, uint32_t cpol, uint32_t cpha, uint32_t dff, uint32_t lsbfirst, ui

Scenario:Able to connect the STM32WB55 as Peripheral/Slave to Master (mobile phone). Communication is mostly solid between these devices, however, during periods of inactivity, the STM32WB55 randomly stops responding to the Master's empty PDU and reverts back to Advertising.Notes:The Max/Min Connection Interval is set as 50 and 100ms via PPCP.Slave Latency and Supervisor Timeout are set to 0 and 1 second respectively via PPCP.The BLE Core Events Handler reports nothing unusual during this event.Thanks in advance for any insight you may be able to provide.

In the datasheet of W25N01GVZEIG,Data program load and quad data program load can transfer up to (2048+64) bytes.(The transfer of data between the controller and the external flash uses DMA)When I try to write 2048 bytes, nothing is written. The same things happen when reading, where nothing is read if the buffer size if 2048.Both only seem to work when dealing with <=40 bytesI have tried to write 2048 bytes and read 40 bytes and write 40 bytes and read 2048 bytes. In both cases nothing is read. Is there something I am missing. The clock's frequency is 170 MHz, and the prescaler of the QSPI is 1

I'm a beginner with STM32 and I'm trying to generate a sine waveform using a STM32G4 through the NUCLEO-G431KB board to be exact. I've been looking through tutorials on how to generate a waveform using a STM32G4 board, particularly this tutorial but nothing has worked — most of the guides I've taken a look at are not for STM32G4 boards which is why I reckon they can't be applicable to the board I'm using. I've also taken a look at this reference manual but I don't know where to start.

I use STM32CubeMX(ver 6.12.0) to configure STM32H7R3Z8T6, when i try to enable FMC to control nand flash, it suggest "NAND Flash 1 is not fully configured. Please enable addresses and data in the Mode section." as followingsomeone please help!!  

Hi,I am new user of ST Microcontrollers. I am using STM32F4 Discovery board.Till now its default HSI oscillator I was using, now I am going to use the HSE clock of this.STM32F4 Discovery board have 8 MHz crystal, which is connected to the microcontroller. when I goto configure through STM32 CUBEMX configuration tool then it shows me a RED lndicator and it shows that clock must be greater than 14.2MHz.Why it is so? Datasheet says that we can use clock frequency ranging from 4-26MHz.Can someone explain me this? How to resolve this issue? 

After normal power-on, the MCU does not run, but as long as something is used to shield it, it will return to normal. Help to see what is the reaso

Hallo,we are using STM32H735G-DK boards and wondering whether unaligned access of memory mapped HyperRAM should be generally possible or not.In the errate sheet for the STM32H735https://www.st.com/resource/en/errata_sheet/es0491-stm32h72xx73xx-device-errata-stmicroelectronics.pdfthere are two issues which may indicate that unaligned access of HyperRAM is not possible:A) OCTOSPI: 2.8.4 Odd address alignment and odd byte number not supported at specific conditionsIn the table it says, that memory-mapped read and memory-mapped write should be possible when the HyperRAM is connected via HyperBus. So this errata should not apply as STM32H735G-DK examples are using HyperRAM in HyperBus mode, or does it?B) FMC: 2.7.3 Unsupported read access with unaligned addre

I have wrote software for recording audio from line in to wav file for STM32H745 discovery board.But output file is distortion (original file and output file is in attachment) Input file and output file is the same sample rate (32khz, 16 bit, 2 channel)I have compared 2 file in audacity in following picture.Could anyone have experiment to fix this problem ?

Hello STM community,I am currently trying to get my Nucleo STM32H743ZI2 to send data via SPI to a different chip.Im using CubeMX to generate a lot of the setup code as I´m pretty new to this chip. For the same reason, I use the HAL.The basic configuration is:The STM32H7 is the masterI'm using SPI1 with SCK on PB3 and MOSI on PB52 Line TxOnlyData Size 8 BitsNSS disabledspi_ker_ck = 80 Mhz, coming from PLL1 DivQAXI Peripheral Clock = 200 MhzAPB1/2 Peripheral Clock = 100MhzMy main loop just tries to send out data repeatedlystatus = HAL_SPI_Transmit(&hspi1, &buffer, 8, 1); HAL_Delay(1);If I set my prescaler to, lets say 8, I can see the data being transmitted with my logic analyzer without a problem. I can also see the EOT bit getting set in the SPI2S_SR register.If I set my prescaler any higher thou

As I understand, the TSSOP20 version needs an external oscillator instead of a 8MHz crystal connected directly to the MCU pins. Is that correct?I'm asking because I have seen a board on AliExpress using this same processor with a 8MHz crystal.

I have a U599 embedded display board, that has a dedicated software pack for TouchGFX.I was able to configure most peripherals on the board, including SD card and FILEX that required THREADX.So far so good, so I activated USB_OTG_HS and USBX. I have it configured as follows:
