Designing custom board based on STM32F746G-DISCO. I am using the TQFP chip, so a few less IO. The DISCO board uses a 4 wide data, but I do not have enough pins so I will only have 1 bit wide data. I only want to use SD card to be able to upload n...
@Tesla DeLorean Hi! I wonder if someone can help me! I am trying to initialize a LCD screen and I have some questions. I am using a STM32F469IIT6, and it does not have enough memory in itself to hold a buffer for my screen 800x480. I did not set up ...
Hello, As a newbie to STM32 , Could some experts please answer these questions for meIs there any basic documentation that provides an overview of what software i will be needing installed on the PC? This is what is my understanding so far, there is ...
Hello, according to the datasheet of stm32g051f8, the absolute max power supply voltage is 4V but the fully charged 1-cell LiPo battery Voltage is 4.2V. Can I power this MCU directly from the battery?
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...
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...
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...
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...
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...
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 ...
