DMA全称为Direct Memory Access,即直接存储器访问。在进行DMA传输前,CPU将总线控制权交给DMA,通过共享系统总线,实现无需CPU参与的快速数据传输,能够直接将数据从一个地址空间复制到另一个地址空间,DMA在数据传输结束后将总线控制权交回CPU。 MM32F0140内置5路 ...
Abstract: In the verification of programs for embedded systems, it is important to reduce the verification time. For this purpose, one solution is to reduce the number of interrupt handler executions.
The HardwareTimer library aims to provide access to part of STM32 hardware Timer feature (If other features are required, they could be accessed through STM32Cube HAL/LL). The use of this library ...
This module shows how the Arduino can be used to time physical events. In this case, we measure the duration of a passing object when it breaks a light beam. If the object has a known length, such as ...
This project combines a sand timer with a rotating mechanism and an optical beam through the center of the timer to observe the falling sand as they create a USB Hourglass. This project combines a ...
