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...
Hello, i have multiple st-link v2 devices that i would like to use on the same machinei have tried it on windows and linux machonei have these commandfor windows: (example)ST-LINK_CLI.exe -c sn=57004800180000535448534E -q -ME -p C:\shared\TFL_CONNECT...
Hello i two questions ,1) i use mcu STM32F042T6Y a give the same power supply 3.3v to pin VDD,VDDA and VDDIO2, is this a problem?(many gpio(i chose the gipo tollerant) input of mcu work to 5V and i use the usb host of mcu )2) i want use a externa...
Hello,I am trying to read voltage, current and frequency from ATM90E26 IC using STM32G491 with SPI communication. I am getting voltage values correctly.1.But while reading frequency value If I give 100 Hz I am receiving 50 Hz.2.While reading current ...
Hi,I am using the nucleo-h563 I3C (Controller mode) to connect to a JEDEC I3C standard DDR5 PMIC chip. The CCC & private communication is doing well by the STM32H563. But when I trying the IBI transfer, I found the IBI request from the PMIC which the...
Hello,I have a dev board based on STM32F030F4. When I try to attach to the device using my Segger JLink Edu, I am getting a "Could not verify ST device" error.Here is the log from Cube:SEGGER J-Link GDB Server V7.88h Command Line VersionJLinkARM.dll ...
