LWIP + FreeRTOS Ping Issues
Hi all,I've been working through this tutorial: How-To-Create to bring up LWIP + FreeRTOS on the STM32H735IGK development kit. I'm using STM32CubeIDE 1.18.0, FreeRTOS with CMSIS-v1, and STM32Cube FW_H7 version 1.12.1I noticed that pinging is very sp...
Resolved! Handling 5V Logic Level Inputs on STM32F103RB (Hall Sensor & SPI MISO)
Hi everyone,I'm currently working on a BLDC motor control project using the STM32F103RB (Nucleo-F103RB) board. I have two questions regarding handling 5V logic signals with this MCU:I need to read 5V logic-level signals from a BLDC motor's Hall senso...
Resolved! Flash drive in Nucleo-F446RE
Hello,When I plug this board to my computer, appears a removable disk of 1,6 MB capacity.Is this disk accessible from the MCU? For store small data, or make a dataloggerWhere the filesystem is stored? Neither the STM32F446RE nor STM32F103CB of the ST...
QUADSPI_BK1_IO3 issue in STM32G474 and STM32H753
Hello.I am testing QSPI indirect mode using STM32G474 and STM32H753.However, I found a weird operation of QUADSPI_BK1_IO3 pin.Other pins are OK, but QUADSPI_BK1_IO3 is high states as in the redboxes.It should be low states (0).I have tested in STM32G...
Resolved! STM32 Black Pill not working with clone ST-LINK V2
Hello everyoneIt's my first time messing around with STM32 microcontrollersA few days back I got a black pill (STM32F401CCU6 - https://robu.in/product/stm32f401ccu6-minimum-system-board-microcomputer-stm32-arm-core-board/) and an ST-Link V2. The blac...
LAN8742A PHY: Unstable Ethernet at 100 MHz
Hello STM32 world!Here are a few words to share our issues—now resolved—with the LAN8742A Ethernet PHY.We designed a board based on the STM32H573, featuring an Ethernet interface.We strictly followed the design used in STM32 boards, particularly the ...
Resolved! Cubemax ADC Clock Issue for NUCLEO-H743ZI
Hi, The default ADC clock source is PLL2P = 80 Mhz in my Cubemax "Clock Configuration" TAB. I can use ADC clock Prescaller to lower it below 50 Mhz. 50Mhz is the max vale for ADC clock. Question: The default setting PLL2P = 80Mhz before...
Resolved! STM32U5xx 100 pin - which one for MIPI DSI and which one for parallel RGB LCD
Hi,In my next project I would like to use 2 type of displays. One with MIPI DSI interface and the other with parallel RGB.That is why I chose microcontrollers from the STM32U5 series ( vector graphics accelelator ).According to the information on the...
Stm32f411ce firmware write failing.
Okay so I have ordered my first stm32 board (STM32F401CEU6 - WeAct Black Pill V3.0 | STM32-base project) for making the flight controller for my drone project. It arrived yesterday, so I began to follow the tutorials, firstly installing Impulse RC dr...
