Hello,Does anybody knows - are 4 wires enough for programming: STM32F411CEU6 module      JP5 of the NUCLEO-WB55RGGND                                        <---- T_VDDSWSCK                                    ??? SWOSWDIO                                   <---- SWCLK3.3V                                        <---- SWDIO                                                ??? NRST                          &nb

I am developing a program to enable the USART3 (initially as a UART) of the STM32H755 (NUCLEO-H755ZI-Q) and use it to transmit information through the functions "__io_putchar" and "printf" but it does not work. At first I thought it was an error in the baud rate calculation, I searched the reference manual and understood that the default clock after the reset is 64Mhz, through the HSI, I made the change, but it still does not work. Here is the file with the settings and functions:#include <stdint.h> #include "stm32h755xx.h" #define SYS_FREQ_64M 64000000 // sys_ck -> 64MHz #define APB1L_CK SYS_FREQ_64M #define UART_BAUDRATE 115200 void UART3_tx_Init(void) { RCC->AHB4ENR |= RCC_AHB4ENR_GPIODEN; // habilita o clock no GPIOD (PD9 - RX) GPIOD->MODER &= ~(0b11 << 18); // limpa os campos do PD9 GPIOD->MODER |= (0b10 << 18); // seta o PD9 no modo alternativo GPIOD->AFR[1] &= ~(0xF << 4); // limpa os campos do PD9 GPIOD->AFR[1] |= (0b011

This is on STM32F103C8 (bluepill)The A0 is connected to a voltage divider between bluepill's 3v3 and GND,And the output is very noisy. adding a delay did't do not much good```void setup(){Serial.begin(9600);// Enable ADC1 and configure itRCC->APB2ENR |= RCC_APB2ENR_ADC1EN; // Enable ADC1 clockADC1->CR2 |= ADC_CR2_ADON; // Turn on ADC1// Configure ADC1 to use the internal reference voltage (1.2V)ADC1->CR2 |= ADC_CR2_TSVREFE; // Enable internal reference voltageADC1->SMPR2 |= ADC_SMPR2_SMP0; // Set sample time for channel 0 (PA0)// Calibrate ADC1ADC1->CR2 |= ADC_CR2_CAL; // Start calibrationwhile (ADC1->CR2 & ADC_CR2_CAL); // Wait for calibration to completepinMode(PC13, OUTPUT);pinMode(A0, INPUT_ANALOG);// configure I2C 2 for Switching controller communicationWire.setSDA(PB11);Wire.setSCL(PB10);Wire.begin();delay(1000);}void loop(){static uint32_t last_time = 0;if (millis() - last_time > 500){// Start ADC conversionADC1->SQR3 = 0; // Select channel 0 (PA0)del

Hello,What should I do to record BLE traffic (data send and received) between STM32WB55 and PC?

When i measure my distance in 4x4 i don't have any issues at all. But I need to change it to 8x8 for my project.To my knowledge you only need to change the resolution with vl53l5cx_set_resolution() to 8x8 and adjust the frequency accordingly. I have checked if my sensor is measuring with my webcam and it is a solid red light so not blinking or anything. And when i check the output it gives me this: Initializeddata not ready??data not ready??data not ready??data not ready??data not ready??data not ready??data not ready??data not ready??data not ready??Status ranging: 1Error retrieving ranging data on device 0.======== Device 0 ========23, 33, 28, 20, 17, 14, 12, 6,24, 33, 701, 26, 19, 15, 11, 10,21, 31, 32, 25, 21, 17, 13, 12,23, 31, 34, 30, 24, 18, 15, 13,828, 27, 33, 33, 0, 22, 0, 0,0, 0, 0, 0, 0, 0, 0, 0,0, 0, 0, 0, 0, 0, 0, 0,0, 0, 0, 0, 0, 0, 0, 0,BrakingError while checking for data ready on device 0.data not ready??Error while checking for data ready on device 0.data no

Hello, Iam trying look for low budget chip for my application, Can you guide if stm32wl33 will work for lorawan communication to send temp. data

what does exactly happen here ? static void WriteCommand(uint8_t cmd) { HAL_SPI_Transmit(&hspi2, &cmd, sizeof(cmd), HAL_MAX_DELAY); } &cmd is address of the variable I wonder if HAL is actually transferring data at that address ?

Hi all!,I notice a different behavior from CubeMX, when starts alone or is called from CubeIDE.When I open CubeMX without CubeIDE, it works as espected. But when CubeMX is open from CubeIDE, it works in a strange way. Per exemple, when I try to put a MCU reference, with every key I stroke it tabs to "search" entry.Anyone with the same problem?Aftermore, this strange behavior happens sometimes, and sometimes dont...Here, CubeMX opened directly:and here opened from CubeIDE:My CubeIDE version: 

i need some assistance with modelzoo . so first of all . i converted a dataset to darknet using converter.py than i trained it using train mode i had a 2.6mo  .h5 file  then i quatized it to 600kb .tflite file. but when i tried to deploy it i had an error saying just exception "wrong"  from compile.py file. so is there any assistances about this error and second of all i realized that despite modelzoo say that he can only deploy tflite models . there are some tflite models that he cannot deploy . ( i tried 4 different tflite models 1 was deployed and 3 did not) so is there any parameters or configurations i should know about  in builiding my model(conditions to be respected) so my model can be compatible with modelzoo

Hello everyone,I and my collegue have more than 20 years experience on embedded desing with MCUs. We have a problem which we haven't seen this kind of problem before. I guess someone can help us in here.MCU: STM32F756IDE: Project created from cubeMX and toughgfx, coded from IARThe main problem is our code jumps unknown address. We have custom bootloader, it runs first and jumps application. After it jumps user application, we initialize every peripherals again. We start freeRTOS kernel and toughgfx task. Actually the code runs well but, sometimes it couldn't run after user application starts.When we dig on it, we saw the code try to jump unknown address which is not on address space. (We get Hard fault or Bus fault or Mem Fault exeption)Anyway, we decided to remove bootloader and try to user code alone. At that moment the code started to do same thing at same location.The code starts from Reset_Handler, initializes stack pointer, goes to SystemInit, iar_program_start and jumps main.You

This is a question about Receive Only Master (SPI_DIRECTION_2LINES_RXONLY).I was able to output the waveform shown in the attachment using Receive Only Master.However, no data is being received(tmp). Why is this? The process is performed in the following order:HAL_SPI_Receive_IT(&hspi2, tmp, data_size);HAL_SPI_Transmit(&hspi4, g_rx_temp_register, data_size, 1000);hspi2(Receive Only Master)hspi4(Transmit Only Slave) About the waveform in the attached image1ch hspi2 clock2ch hspi2 MISO

In the CubeProg, (for instance) the RCC_D1CCIPR value names (*SRC) are different than in the RM 0433 (*SEL). Such things are a bit annoying, if one tries to find things by a keyword search, of if unsure about "is it really the same entity"? Can someone here pass this to the authors for fixing? Thank You! - CubeProgrammer v2.17.0- RM0433 Rev. 8, p. 496 

The reference manual 0433 Rev 8, p. 900, section 23.5.5 says "This bitfield has no effect when in memory-mapped mode (FMODE = 10)." But p. 901, section 23.5.6 says: "11: Memory-mapped mode".Could someone please let the authors fix this?Thank you.

Hello,I have an ISR for TIM4 running on an STM32F2 microcontroller. The ISR triggers on a rising edge of the timer input channel, and its purpose is to record the microsecond timestamp of the last two rising edges in global variables for other parts of the firmware to use.void TIM4_IRQHandler(void){second_last_re_us = last_re_us;last_re_us = time_us();TIM4->SR = 0;}I notice that the ISR as written triggers twice on each rising edge. This is evident by last_re_us and second_last_re_us reading as equal, even when the PWM signal being input is only in the hundreds of hertz.If I move the IRQ flag clearing to the beginning of the ISR, or if I add barriers before returning from the ISR, the issue goes away, and the ISR gets called only once. This is evident by last_re_us minus second_last_re_us giving the expected period of the PWM signal I am inputting.void TIM4_IRQHandler(void){TIM4->SR = 0;second_last_re_us = last_re_us;last_re_us = time_us();} void TIM4_IRQHandler(void){second

Hello,I've noticed that the generated CMake projects (specifically, in the toolchain gcc-arm-none-eabi.cmake file), a now-deprecated (since version 3.6!) macro is used https://cmake.org/cmake/help/latest/module/CMakeForceCompiler.htmlI have to remove/comment out the use of these macros in my code due to it causing issues with other CMake libraries that I use in my project, which somewhat defeats the purpose of the CubeMX generated code to begin with.Hopefully this is seen by the right person and this issue is addressed. Thanks!

Hi Foued,I'm going to connect 10 BMI323 IMUs to STM32H503RB MCU by I3C bus. BEI323 supports I3C and dynamic addressing and 0x68 static address. Is it possible for I3C bus of STM32 to recognize all IMUs by assign different I3C addresses to make all of them working? Thanks! Yx

Hello.Looking for a reference circuit diagram of STM32F723VET6.If not, I'm looking for a circuit diagram of 32F723 EDISCOVERY.Please give me a link.The reason is that I want to use vdd as 1.8V instead of 3.3V, but I want to refer to it. think you.

Hi,I use the BLE_p2pServer example as a basis and would like to forward the transmitted data directly to the UART1 interface. My idea would be to use here (in p2p_server_app.c) a HAL_UART_Transmit_DMA() function, but I fail to access the data due to an incorrect type conversion. case P2P_SERVER_LED_C_WRITE_NO_RESP_EVT: /* USER CODE BEGIN Service1Char1_WRITE_NO_RESP_EVT */ if(p_Notification->DataTransfered.p_Payload[1] == 0x01) { // HAL_UART_Transmit_DMA(huart, pData, Size); ... here i want to insert the UART transmission funkction BSP_LED_On(LED_BLUE); LOG_INFO_APP("-- P2P APPLICATION SERVER : LED1 ON\n"); P2P_SERVER_APP_Context.LedControl.Led1 = 0x01; /* LED1 ON */ } if(p_Notification->DataTransfered.p_Payload[1] == 0x00) { BSP_LED_Off(LED_BLUE); LOG_INFO_APP("-- P2P APPLICATION SERVER : LED1 OFF\n"); P2P_SERVER_APP_Context.LedControl.Led1 = 0x00; /* LED1 OFF */ } /* USER CODE END Service1Char1_WRITE_NO_RESP_EVT */ break; In p2p_server.h are the

Hi AllI have created a PCB where I want to use the OCTOSPI to communicate with a FPGA.I have difficulty finding accurate information on how the different memory types work. I already have a Hyperram running so I started there, that did also seem straight forward.I do currently only have FPGA code listening and is focusing on getting write to work.I slowed down the clk quite a bit to only fucus on functionality. Pre scale of 30 ~9.6MhzI would much like to have the FPGA memory mapped, so that's what I'm testing.When I write to address 0x91234568 (0x90000000) is octospi1 basewith the data of 0x87654321 then i get following sequence in hex:20 12 34 56 00 04 43 21 87 65The Data is easy, that's just different order 43 21 87 65 instead of 87 65 43 21The 20 seems to be CMDThe Address (in correct order) 12 34 56 (but then always 00 00 or 00 04) as the last, I seem to lack the last nibble of the Address.  The RWDS Seems a bit early.if I Change to 0x91234560  then  t

EMB1428QSQ/NOPB is used which has the frequency of the 1.1MHz fclk and the SPI2 of STM32F469BIT7 is going as a clock to it. I need the minimum value of the SPI2 master that can be fed to the EMB1428QSQ/NOPB. Also, where can I find the minimum frequency of the communication interfaces , I have used the USART and SPI2.

Regarding the problem that CTSIZE becomes 0x01 after SPI communication is completed,In our program, SPI-SR-CTSIZE becomes 0x01 after SPI communication is completed.In that state, if we try to perform the next SPI communication, a timeout error occurs in the middle of the communication.When SPI-SR-CTSIZE = 0, no timeout error occurs.Is there any way to set SPI-SR-CTSIZE (= TSIZE number of frames in a session) to 0?Translated with DeepL.com (free version)

Using the latest SM32Cube_FW_WL_V1.3.0 and the lorawan middleware.For MAC v1.0.4 the devnonce and other parameters needs to get persisted to the flash.  From what I see this happens when LmHandlerNvmDataStore is called.But from the looks of it, this is never called?  I assume I am missing a file somewhere!?Any idea where and when this function is getting called? 

I am programing the STM32L4S9AII6 using the STM32L4R9I-EVAL board. My application requires the use of 5 different SPI buses, but the STM32L4S9AII6 only has 3 standard SPIs. However, it has 2 Octospi buses that I understand can be configured to be standard SPIs. Is this true or have I been mislead? Can someone shed some light on how to configure an Octospi as a standard full-duplex spi? Preferably using MxCube. More specifically, I want it to be equivalent to this standard SPI configuration:
