Hi , I am using STM32L072CBT6 MCU for my project. I have to use the USB pins of the controller, but in datasheet it shows the minimum preferred USB VBUS voltage is 3V. But the thing is in the same datasheet the USB VBUS voltage range is mentioned as ...
Hi, I'm using NUCLEO-H743Z1 board with FreeRTOS+TCP stack. In the network interface of the stack I have configured the primary MAC address as 0x00:0x11:0x22:0x33:0x44:0x46 which gets written into the MACA0HR and MACA0LR registers in HAL_ETH_Init(). W...
I am trying to program a stm32f030cct6 with a ST-Link v2. When I try to connect using CubeProgramer says: "Tarjet not found". I connect to NREST, CLK and SWDIO, I'm measuring the signals with an oscilloscope and SWDIO is in PullDown when it should b...
I am using nucleo L4R5ZI-p i am trying to use USB with for virtual comport the and i am following STM32 tutorials for USB driver development when i am connecting usb to the device the device manger in sot able to read showing this dialog box Note ...
Hi,I am trying to run my application on the STM32L433RTCX which includes the code that enables the RDP to level 1. Even after multiple different attempts (to set it at level 1) the application on the MCU is still not working. Details from my side - P...
Hello !I am currently trying communication using the CANBUS from a nucleo-f411re to an arduinoI used to work with an MCP2515 (using the CS, MOSI, MISO, SCK pins) and i now want to work with an MCP2551 using the RxCAN and TxCAN pins. My setup looks li...
I'm working with the STM32F7 microcontroller and I compile using STM32CubeIDE. I want to place myStruct on a specific location in RAM and I want it be initialized automatically:MEMORY { ... MY_STRUCT_MEMORY(rwx): ORIGIN = 0x20007BA0 LENGTH = 8 ...
I am measuring temperature from sensor via i2c in a loop with one second delay. There are various other functions also in loop. Those functions may take time from 10ms to 500 ms depending on Rx_Callback. I need to measure rate of change of temperatur...
I am currently working on a PCB that involves an STM32F446RETx microcontroller. I've encountered some difficulties in selecting a suitable 16MHz HSE crystal oscillator.Since my intention is to order the board from JLCPCB and avoid any manual solderin...
Hello to everyone,I have an issue with the MCU in the title. I am about to show you my problem in some steps:1- What is the flash memory size of my microcontroller? I consulted the datasheet of device and I read: So, for this series, I can have up to...
