Solved

Please, i would like to know datasheet about this component. Someone could help me? because i need to change this component, and i can´t find it´s in my city.

I've seen this around and I was hoping to get additional information on how to track down why this is the case.I'm writing a Neopixel driver for an STM32F411RE based on this example. The example works good, and I've been working on getting a struct-based version of the code going so that I can have multiple Neopixel strips of variable lengths attached to one microcontroller.I've run into a problem where HAL_TIM_PWM_PulseFinishedCallback isn't being called, which (according to this post) means CC1 isn't being reached. I've been trying to diagnose why that isn't happening, but I've been coming up short. This is the code in the driver:  #define NUM_PIXELS 40 #define RGBW_DMA_BUFF_SIZE (NUM_PIXELS * 32) + 1 typedef union { struct { uint8_t w; uint8_t b; uint8_t r; uint8_t g; } color; uint32_t data; } PixelRGBW_t; /* * Note, must use a 32bit timer channel to work. */ typedef struct { TIM_HandleTypeDef* timer; uint32_t timer_channel; uint32_t pixel_len

Hi,I want to make the system with stm32f4 series mcu. An important function of the system is to control the Ethernet speed.Is it possible to adjust the Ethernet speed with such detailed figures as 65Mbps, 38Mbps, and 300Kbps??If possible, how can I adjust it? When I looked at the data sheet and reference manual, the only values that could be set at the register level were 10Mbps and 100Mbps.I thought Changing the main operating clock on the mcu could increase and decrease the Ethernet speed, but would the way I thought work?

Hi I want to use the STM32U5A9VJ6Q_SMPS inbuilt chip in one of my projects. I plan to run the chip with 3.3V. Is it feasible to run at 3.3V for all pin functions?    

I want to use the VD55g1 camera on widows but i am not able to find the right driver 

Hi,I am confused on how I can get this board: EVLDRIVE101-HPD, to work.For context, I am simply trying to get the EVLDRIVE101-HPD to run a compressor motor.From my understanding, I believe I need to generate the code/firmware through MCSDK workbench and then compile the code through an IDE (im using STM32CubeIDE) into the EVLDRIVE101-HPD board with the STM32G071KBT. However, both softwares do not have the board (EVLDRIVE101-HPD) as an option in the setup.I have the board's JSON file which I believe can be imported in the MCSDK workbench but need further instructions on how?Could I please have some general help with this? As well as clear instructions on how to get this board to work with my motor?Any help will be appreciated. thanks!

IMHO in the file "stm32f3xx_hal_def.h" the section "Exported types" should be moved in front off section "Includes", because some of the types are used in the included files, but "stm32f3xx_hal_def.h" will not be reentered. It produces error like this: In file included from .\Core\Inc/stm32f3xx_hal_conf.h:203,from .\Drivers\STM32F3xx_HAL_Driver\Inc/stm32f3xx_hal.h:29,from .\Drivers\CMSIS\Device\ST\STM32F3xx\Include/stm32f3xx.h:266,from .\Drivers\STM32F3xx_HAL_Driver\Inc/stm32f3xx_hal_def.h:29,from .\Drivers\STM32F3xx_HAL_Driver\Inc/stm32f3xx_hal_rcc.h:27,from Src\setup.cpp:9:.\Drivers\STM32F3xx_HAL_Driver\Inc/stm32f3xx_hal_gpio.h:297:1: error: 'HAL_StatusTypeDef' does not name a type; did you mean 'NOR_StatusTypedef'?   

I am working on a project that uses a PWM on a timer to drive a buzzer.  When the buzzer stops I need to set the output compare signal high.  The timer set ARR to 250, and the compare value to 125, giving a 4kHz square wave with a 50% duty cycle.   I start the timer by enabling it (TIM2->CR1 &= ~TIM_CR1_CEN), and stop the timer by disabling it. (TIM2->CR1 |= TIM_CR1_CEN).  What I need to do is make sure the output is high when it is disabled.  I tried setting the count value (TIM2->CNT = x) and thought that if I set the count below the 125 threshold, the output would stay low, and if i set the count above the 125 threshold, the count would stay high, However setting the count seems to make no difference to the output compare level.Anyone have any idea how I can stop the count with the output compare in a defined state?

Hello, I'm practicing with dynamic indication on multidigit multisegment indicators, and run into the issue when on the screen appear some symbols that are not supposed to be printed. I'm using 3641AS, each segment is connected to PC0...7 via 2K2 resistor, and each digit's pin is connected to PC8...PC11.The code is:  /* USER CODE BEGIN PV */ // binary presentation of numbers from 0 till 9 int numbers[10] = { 0b00111111, 0b00000110, 0b01011011, 0b01001111, 0b01100110, 0b01101101, 0b01111101, 0b00000111, 0b01111111, 0b01101111 }; // the variable to be shown and changed during run of program int value = 0; // the decimal place to be depictured at the momen int current_digit = 0; // bitmasks of decimals to be depictured (including decimal point) int digits[4] = { }; #define display_interval 5 #define count_interval 1000 uint32_t last_display_tick; uint32_t last_count_tick; uint32_t current_tick; /* USER CODE END PV */     /* USER CODE BEGIN 2 *

I am currently developing UART functionality on the SPC58EG chip, and I want to use LinFlexD1 hardware channel to develop UART.However, I cannot find relevant examples in the SPC5 Studio IDE.I am referring to the official manual (RM0391), which mentions that the Peripheral Sensor Interface-Support module (PSI5-S) must be enabled and related registers modified to use LinFlexD as UART.Are there any more specific example codes or projects that can be used as a reference for developing UART?Thank you.

This is a long one, so sit tight around the campfire, and let me tell you the tale of The Futility of EPENA.Several days ago, I began to implement a Mass Storage interface for my own USB stack, equipped with a Bulk IN and OUT endpoint. The first thing I did was wait for the OTEPDIS interrupt ("OUT token received when endpoint disabled"); this lets me know that the host wants to send me a love letter, that is, a Command Block Wrapper. This OTEPDIS interrupt is a little strange, however, as RM0351 (Rev. 10) states that this interrupt only applies to Control OUT endpoints, but nonetheless seems to have effect for non-Control EPs (at least for the STM32L476RG).Anyways, on this interrupt, I then configure the Bulk OUT endpoint to receive a single 8-byte packet in order to get the first 8-bytes of the 31-byte CBW. Of course, I could just have a 64-byte EP so it could be received in-all-one-go, but I wanted to ensure the flexibility of my own USB stack in being able to handle multi-packet tra

  Hello, I've designed a PCB with a schematic nearly identical to the STEVAL-WBC86TX. The only modifications are a capacitor and coil size change, which I've also implemented on a development board for direct comparison. On the development board, my receiver PCB performs almost flawlessly, with the only issue being a charging current of around 60mA (which may be unrelated). However, on my new transmitter board, it almost immediately overheats and shuts down. I've attached an image from WPSTUDIO showing the temperature reaching 100°C before shutting down and repeating this cycle. Can anyone suggest potential causes for this issue or point me in the right direction for troubleshooting? Thank you, Mike

Hello,On my project, I use FDCAN1 and FDCAN2. FDCAN1 is working perfectly fine.On FDCAN2, I can transmit data successfully (with the CAN ID 0xBEEF), but when I want do receive data, the Rx callback is never called, nor the IRQ handler (the CAN ID filter is set to 0xDEAD).CAN ID is configured as extended ID mode.Here's my FDCAN2 init function:static void MX_FDCAN2_Init(void) { /* USER CODE BEGIN FDCAN2_Init 0 */ /* USER CODE END FDCAN2_Init 0 */ /* USER CODE BEGIN FDCAN2_Init 1 */ /* USER CODE END FDCAN2_Init 1 */ hfdcan2.Instance = FDCAN2; hfdcan2.Init.FrameFormat = FDCAN_FRAME_CLASSIC; hfdcan2.Init.Mode = FDCAN_MODE_NORMAL; hfdcan2.Init.AutoRetransmission = ENABLE; hfdcan2.Init.TransmitPause = ENABLE; hfdcan2.Init.ProtocolException = ENABLE; hfdcan2.Init.NominalPrescaler = 32; hfdcan2.Init.NominalSyncJumpWidth = 2; hfdcan2.Init.NominalTimeSeg1 = 2; hfdcan2.Init.NominalTimeSeg2 = 2; hfdcan2.Init.DataPrescaler = 1; hfdcan2.Init.DataSyncJumpWidth = 12; hfdcan2.Init.D

Dear Team, When I am starting a new project in cube MX with STM32H7R7L8H6, there are options of I2C1 and I3C1. but I am not able to select and make it work. drop-down menu is not enabled!I am using V 6.12.0 Does anyone have any explanation for this? RegardsUmang

Hello, I'm trying to set up the deep sleep mode for VL53L8CX using NUCLEO L476RG board so as described in the datasheet that it can operates in 3 different states:• Wake-up: The device is set in HP idle (high power), waiting for instructions.• Sleep: The device is set in LP idle (low power), the low power state. The device cannot be used until set inwake-up mode. This mode retains the firmware and the configuration.• Deep sleep: The device is set in ultra-low power. In this mode, the sensor consumes a few microamps ofcurrent. However, the firmware, configuration, and calibration data are completely lost. The user needs toset the device in wake-up mode and reconfigure the sensor to start streaming.   But the only result i'm getting using api functions are wake-up and sleep mode but not the deep sleep one Can you please help me to get it working

I am a beginner in this field. Can anyone help me?I am testing Adafruit VL53L4CD and Arduino Nano with Atmel ATmega328P 16 MHz processor.Only 10 cm. wire is connecting the Adafruit board and the Nano board.I have an issue with status code using ST VL53L4CD_Sat_HelloWorld.ino sketch.inoWhen distance is below approx. 500 mm. Status = 0 (OK).When distance is below approx. 1.400 mm. Status = 2 (Wire: Received NACK on transmit of address?)When distance is above approx. 1.400 mm. Status = 4 (Wire: Other error?)Some times also status = 7?The status may originate from Wire.endTransmission()I have analyzed the I2C protocol using PicoScope. I can't figure out what's wrong. Se oploaded image.I would expect nice square shapes for SDA and SDC. But that is not the case?Regards Joergen

Hi everyone. I hope you are well.I am researching how to write LD file. I listened external flash pins. I used an "External Flash Loader file" to program the external Flash IC and MCU. I used STLDR file that work. I will write stages step by step; 0x06 : Write Enable 0x05 : Read status, -> Response: 0x02 0xD8 : Block Erase 0x05 : Read status, -> Response: 0x03 ...//Repeat 0x05 command 0x05 : Read status, -> Response: 0x00 // Block erased. ... 0x06 : Write Enable 0x05 : Read status, -> Response: 0x02 0x02 : Page Program 0x05 : Read status, -> Response: 0x03 ...//Repeat 0x05 command 0x05 : Read status, -> Response: 0x00 // Page programmed. ... I created a my custom STLDR file. Programmer(Stm32Cube) is "known" my STLDR file. But My MCU and Flash IC can not be programmed. I take error. And I listened again. My STLDR file use different procedure to program. Is not like above. 0x66 : Reset 0 0x99 : Reset 1 0x06 : Write Enable 0x20 : Sector Erase 0x05 :

Hello everyone,I have been working on a custom bootloader for the STM32H735 microcontroller and I am encountering an issue when attempting to jump to my main application stored in external flash memory. Here's a brief overview of what I've done so far:Developed a Demo Bootloader: I started by creating a demo bootloader based on the ExtMem_Boot example. This bootloader successfully jumps to applications stored in external flash memory. Both a simple application (printing RTC values, just for TESTING) and a more complex application with multiple functionalities work perfectly when jumped to from this demo bootloader.Developed a More Complex Bootloader: I then developed a more complex bootloader that includes functionalities like CRC calculation, erasing sectors, and loading a new image from an SD card. This bootloader also successfully jumps to the simple RTC application without any problems.Encountered Issues with Main Application: However, when I attempt to jump to my main application

hello ! OV2640 is used as the camera module and I want to use GPDMA when I send DCMI data. If MX sets up like this and generates codeThere's an error like this (handle_GPDMA1_Channel12' undeclared (first use in this function); did you mean 'handle_GPDMA1_Channel0'?) So please let me know how to use GPDMA in DCMI or OV2640, in STM32U5AZJ.    

Hello, I wanted to share an issue I found with enabling the oversampler for ADC using HAL. I was having issues result not being bit shifted. Further investigation I found that the HAL driver version 1.11 did not write the OVSS bits correctly.
