Solved

Hello guys can someone please help me change the graphic on the display through the code? My boss sent me a video in French, which I don't understand at all. I've already Googled and searched but haven't found anything yet. I'm using the STM32746G-Discovery board. For example I schould change a toggle button on the Display, only through the code. Does anyone knows a Website or a Video which explains that, please share it.  

Dear Support Team,I am encountering an unexpected issue with my STM32H743IIT6 microcontroller where the GPIO operation frequency observed via an oscilloscope is only ​16.6 MHz, despite configuring the ​bus clock at 400 MHz and ​AHB clock at 200 MHz. Below is the code snippet I am using for testing:__attribute__((section("RAM_CODE"))) void gpio_test() { while(1) { GPIOB->BSRR = 0x02; /* PB1 set high */ GPIOB->BSRR = 0x020000; /* PB1 set low */ } }   STM32F407 168M clock, GPIO with the same code can reach 33M

Hello,I'm trying to generate code from a CubeMX project for STM32MP257f-ev1: my concern is that I've turn on PLLs from CubeMx Clock Configuration tab but code for PLLs clock configuration is not generated in SystemClock_Config function. In main.c I get only the following:void SystemClock_Config(void){__HAL_RCC_MCO1KERCLK_SETSOURCE(RCC_MCO1CLKOUTPUTSOURCE_CLK_MCO1);}Maybe I missed something but I can't find out, can someone please help me?In attachment you can find the project .ioc fileMarco.

Helloi have a pair of X-NUCLEO-PLM01A1  plugged on two NUCLEO-G071RB that communicate in P2P mode, one is master board and one is slave boardi have adapted the example provided by ST to work on this boards: https://www.st.com/en/embedded-software/x-cube-plm1.htmlThe communications  using a 2 wire to connect the CN1 on the  X-NUCLEO-PLM01A1 is completely functionalBUTif i try to connect the two board using two STEVAL-XPLM01CPL is not working anymorei connect the two high voltage side on the 230VAC 50Hz same socket and the two low voltage side to the respective X-NUCLEO-PLM01A1 there is some modification to do on the example or should be work?anyone have the same issue ? 

Hi Supporter:     I attempted to train a model using NanoEdge AI Studio,Some errors occurred!    first,I create a NC-class project (ps:I haven't connected the development board. I'm just using the computer for simulation.)    add signal benchmarkWhen I clicked "Start," the screen stuck on this page and stayed there all day, only to be closed through the task manager.What's the problem? 

Is it possible to synchronize two separate pairs of HRTIMER channels using the HRTIMER Master?My goal to is to synchronize HRTIMER_E with HRTIMER_C and HRTIMER_F with HRTIMER_A. Each HRTIMER pair needs to operate independently of each other.The reason for this is as follows: HRTIMER_E1 and E2 control a resonant converter. A fault coming from COMP6 (hrtim_flt3) needs a blanking source, which can only come from HRTIMER_C, therefore these timers need to work in sync. HRTIMER_F1 and F2 control another resonant converter, where a fault coming COMP2 (hrtim_flt1) needs a blanking source that can only come from HRTIMER_A.The two resonant converters work independently, so the syncing of the timer pairs needs to be independent.A workaround is to use external event capture instead of the faults to keep the blanking source within the timers driving the converters. I like the faults because they can turn the outputs off in hardware.

Hello    For the Nucleo STM32WB05KZ board, the transmission power is normally 0 dBm by default (it can go up to 8 dBm). Is it possible to modify the transmission power according to my needs, for example to 3 or 4 dBm, using STM32CubeProgrammer or another software?   thanks

hi all,i was trying to work with stm32u585 microcontroller and an external RAM IS66WVQ2M4DALL , which is a QSPI based RAM can work in 133Mhz.the RAM support DDR based data transfer.

Does the STM32G491KC have Quad SPI capability? The documentation and product selector tools (on website and within Cube IDE) say that it does have QSPI, but when I try to configure it within the Cube IDE the options is grayed out with the message "Dual Bank mode must be enabled"  

Hello,AN4879 Rev 6 - April 2023 does not mention STM32G0 and STM32G4 USB functionality, also the series has been release since some time. Explaining similarities and differences to the other series wooul be usefull

On this page: https://www.st.com/en/microcontrollers-microprocessors/stm32wle4c8.htmlThe device is specified as having LoRa support in the first paragraph of the description but lower down in the "More from the product line" section the WLE4 chips are indicated not to include LoRa. Also the product selector filtering includes WLE4 devices when LoRa is filtered for.The datasheet says: "The LoRa® modulation is available in STM32WLx5xx only." so I think the web site is incorrect?

Hi,My board with a STM32F745VEH6 is working as a device, that need to be updated via USB C over time. How can I do that? Is there a way to update the firmware with command line?I tried to connect the micro over USB C with STM32CubeProgrammer, and got this error:Do I have to have a ST-LINK on the board? Or use FTDI cable?   

I'm building an application for a BlueNRG-LPS (332), now rebranded as STM32WB05TZ (WLCSP-36 Package) by starting with a simply Blinky project testing the clock signals of my device. I need to enable the PLL64M clock source to use the radio peripherals, and the generated configuration fails. Maybe I'm missing to add or properly set up something here?Context:I'm using STM32CubeIDE 1.16.0 with STM32Cube FW_WB0 V1.0.0 to generate some basic code.Initially, all the Radio Peripherals are OFF, I'm using a 32MHz external crystal for the HSE, and do not have an LSE installed on my PCB (planning to have one, but for now, using the LSI). In my particular case, I added external 12pF capacitors to my HSE crystal, and set the chip's internal tuning capacitors to 0. (Ignore the inductor symbol, this is only a 0ohm resistor) The PCB has the hardware to not work on SMPS mode (no Inductor), tried 2.4V and 3.3V as the VDD source with similar results.My clock tree initially looked like foll

Hi, I am sampling high rate data using STM32L476 in Nucleo64 board in dual channel interleave mode. I am measuring very low voltage values so is it possible to use MCUs internal opamps together with interleave mode. It looks like I am not able to activate interleave mode when I activate opamp and I couldnt find information on whether or not they can be used together. What I would like to do is basically amplifying my signal before entering to ADC without any external component. I appreciate any advice.

Hello everyone,I need to implement the burst controller in HRTIM in order to load 3 compares of the master timer at once.I am using low layer so I do not have a lot of info.My .ioc setting are:Then, in the DMA CH1 interruption I have something like that.  cmp_values[0] = cmp_value_C; // intended for the second burst register cmp_values[1] = cmp_value_A; // intended for the first burst register cmp_values[2] = cmp_value_D; // intended for the third burst register LL_DMA_DisableChannel(DMA1, LL_DMA_CHANNEL_4); LL_DMA_ConfigAddresses( DMA1, LL_DMA_CHANNEL_4, (uint32_t)cmp_values,(uint32_t)&HRTIM1->sCommonRegs.BDMADR , LL_DMA_DIRECTION_MEMORY_TO_MEMORY); LL_DMA_SetDataLength(DMA1, LL_DMA_CHANNEL_4, 3); LL_DMA_EnableChannel(DMA1, LL_DMA_CHANNEL_4); The problem I am encountering is that the 3 compare registers are updated only with the first element of the buffer. I have memory incremental desactivated. If I activate incremental in memory, it does note even load

I am using Nucleo-H7S3l8 board which has STM32H7S3L8H6 MCU and Macronix NOR Flash MX25UW25645GXDI00. Using XSPI Interface, I am trying simple read device id command RDID. After I send the command, observed busy(BUSY of XSPI_SR) bit going high and FIFO level(FLEVEL of XSPI_SR) bit field with some value and both the both fields got cleared immediately and when I try to read from data register, got no data.Can someone suggest what might have gone wrong or suggest a way so that I can get Device Id?

Hello,I'm working on a project started from Zigbee_APS_coord and Zigbee_APS_router examples on NUCLEO-WB55.USBDongle with STM32Cube_FW_WB_V1.21.0.The project is based on data exchange between the coordinator and several devices acting as routers (from 2 to 10) at the APS layer. The commonunication works fine in unicast mode, but I got error ZB_APS_STATUS_ILLEGAL_REQUEST = 0xa3 from ZbApsdeDataReqCallback if I try to send a broadcast message with the following code: struct ZbApsdeDataReqT zb_aps_req_current; struct ZbApsAddrT dst; dst.endpoint = clusterId; dst.mode = ZB_APSDE_ADDRMODE_SHORT; dst.nwkAddr = 0xffff; /* Broadcast */ memset(&zb_aps_req_current, 0, sizeof(zb_aps_req_current)); zb_aps_req_current.dst = dst; zb_aps_req_current.profileId = profileId; zb_aps_req_current.clusterId = clusterId; zb_aps_req_current.srcEndpt = srcEndpt; zb_aps_req_current.asdu = payload; zb_aps_req_current.asduLength = payloadLength; zb_aps_req_current.asduHandle = zigbee_app_inf

Hello!I am using the onboard STLINK on the NUCLEO-U031R8 to program a STM32U0 on a custom PCB. I use the SWD interface connected over jumper wires and programming works fine. I would like to enable printf for debug purposes, and since SWV is not available for this series, I am trying to connect USART2 from my PCB to the STLINK using fly wires. However, I can't seem to find where the TX and RX pins are exposed on the STLINK. The jumpers and CN3 mentioned in section 6.8 of UM1724 also don't match up. On further inspection, it seems that some Nucleo boards have the TX and RX pins exposed as a header, but my particular one does not. Is there a way for me to use VCP this way with this Nucleo board? Thank you in advance! 

Can someone help me with a clock configuration for STM32H7 with 8mhz crystal (I can change it if need) so I can get 0% drift for 44100Hz Audio?   

I am using the STM32L4 B-L475E-IOT01A board with the following modules:Wi-Fi module Inventek system ISM43362-M3G-L44Bluetooth module SPBTLE-RFDocumentation: https://www.st.com/resource/en/user_manual/um2153-discovery-kit-for-iot-node-multichannel-communication-with-stm32l4-stmicroelectronics.pdf The problem is that currently both are using SPI3 and both need different bits and prescalers to work properly. Therefore, I am trying to use USART3 instead of SPI3 for the WiFi module (since the BLE module has only one possible interface, SPI3).My question: How to use the WiFi module via USART, so that I can use SPI for the BLE module? Or are there any other ways to use both modules simultaneously?  

I'm working on a STM32H755ZIQ.  I am setting up a SPI master, with CPol= 0, CPha = 1, accordingly I need the clock to be low when inactive.  Additionally I want the clock to be low when idling, even when the SPI is not active. To achieve this, I have modified the GPIO settings to use a pulldown resistor on the clock pin.I set this up using the CubeMX utility, but I don't necessarily trust it, so I have checked the generated code, and I find, in main.c, within the function MX_SPI1_Init(void), the polarity is set low:and also, in stm32h7xx_hal_msp.c, within the function HAL_SPI_MspInit(SPI_HandleTypeDef* hspi), the GPIO is set to use the pulldown resistor:And yet, the clock is idling high. You can see in the logic trace below, that the clock is NOT normally pulled down, but only goes low when the SPI is activated.  I assert the CS pin before carrying out an SPI write operation. The clock is still high when the slave detects the CS change, and the slave fails

Dear ST community,I'm trying to setup a ML inference project on the STM32N6 Nucleo in order to do latency and accuracy evaluation of models as well as power measurements.

Hi,I am developing an application with the LIS2DW12 accelerometer where it is reconfigured depending on which state the application is in. In one state, the accelerometer should detect when it is stationary/in motion and trigger pulsed interrupts on INT2. In another state, the accelerometer should wake up the system upon movement by triggering a latched interrupt on INT1. The only way I have managed to get this functionality is by, when the accelerometer is being reconfigured for wakeup, setting INT2_ON_INT1 in CTRL7. Without this setting, INT1 does not react to movement at all. I figure there must be a way to get INT1 to fire without having to route INT2 to it, so what am I missing?I have tried following the wakeup example without success.These are all the register contents after reconfiguring for wakeup, with INT2_ON_INT1 set:LIS2DW12_OUT_T_L = 0x70 LIS2DW12_OUT_T_H = 0xfb LIS2DW12_WHO_AM_I = 0x44 LIS2DW12_CTRL1 = 0x60 LIS2DW12_CTRL2 = 0x0c LIS2DW12_CTRL3 = 0x10 LIS2DW
