Hello, I have a question about the FSMC and FMC protocols in the F4 series. Well, I have a configured 4" waveshare display configured for FSMC in STM32F407G. Due to lack of space in the flash, I am forced to add memory (I want to do it using QUADSPI,...
Greetings, I am trying to blink LED using baremetal programming. I am just starting bare metal programming. My LED on Nucleo - F070 board is not being turned ON. I checked register values on data sheet and user manual and it seems to be correct. RCC ...
How to connect two MIPI DSI LCDs to an STM32 microcontroller such that both displays receive identical data?
Hello,I am trying to implement the FDCAN in classic mode on the STM32G491 without the HAL. But I am havin trouble understanding how to configure and then use the CAN SRAM. I am not using the HAL nor CMSIS nor anyting else. Just the basic register def...
您好： 我现在使用的RTL8211E-VB的PHY芯片，，PHY芯片的数据手册中明确表示了，ETH_TX_CLK信号是需要由单片机产生。如下图所示： 而STM32H743VGT6单片机在HAL_ETH_Init函数中会在下面这段代码中返回错误： /* Wait for software reset */ while (READ_BIT(heth->Instance->DMAMR, ETH_DMAMR_SWR) > 0U) { if (((HAL_GetTi...
hello all;i wondered if there are good guidelines for power consumption vs. clock, and, how low can the processor clock run? complex, i think, especiallly if one needs to run certain peripherals like ADC, or i2c... thanks!
Hello, ST expertE.g. GPIO PD4 functions as falling edge interrupt pin on STM32F407. Before the falling edge this interrupt is disabled by HAL_NVIC_DisableIRQ(EXTI4_IRQn). What happened if HAL_NVIC_EnableIRQ(EXTI4_IRQn) is executed after the falling ...
Hello I am having an weird issue and was hoping if someone could provide some guidance. Hardware : Two Stm32 H7 with CAN TranscieverNvidia OrinCan Adapter/Sniffer (Canable) What works : Stm32H7 to Stm32H7 Nucleo Board Can Bus works.Nvidia Orin < - >...
Hi all,I'm working with STM32F4 discovery board, and I'd like to know if I can use one timer with interrupt to capture multiple time.For example I'd like to use TIM16, and be able to check 4 times : 150ms, 250ms, 500ms and 1000ms is it possible? Afte...
Hello ST Community,I am currently working on a project using an STM32 microcontroller, where I have implemented a feature to transmit the current date and time over USB when a user button is pressed. The USB transmission is handled using the CDC cla...
