Bare Metal FDCAN on STM32G491
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...
STM32H743VGT6 与RTL8211E-VB使用MII Full Duplex Only模式无法正常工作
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...
Resolved! power consumption vs. clock rate 32L4xx ?
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!
Resolved! a problem about interrupt enable after the interrupt happened
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 ...

Resolved! User timer interrupt for capture multiple time
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...
Resolved! Issue with Consecutive USB Transmissions in EXTI Callback
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...
Different ADC Channels Reporting Values from other Channels when Polled (STM32G0)
Hello,I have seven ADC channels in my design. I have probed these channels and can confirm from an analog standpoint the signals are clean, and are stable when read from using the ADC. I have read from each channel and received expected values, howe...
USART2_LPUART2_IRQHandler fired when no interrupts are enabled in control register
Hello, The cpu is STM32G0B1. I am developing the interrupt-based UART driver using FIFO and software circular buffers. The main point is, that I don't fully understand the mechanism of interrupts. I enabled two interrupts in CR3 register using RXFTIE...
