In STM32, there are five clock sources for HSI, HSE, LSI, LSE, PLL.In fact, four clock sources, as shown (gray-blue), PLL is a PLL clock that is multiplied by a phase-locked loop circuit. ①, HSI is a high-speed internal clock, RC oscillator, frequency of 8MHz.　　②, HSE is a high-speed external

Crystal oscillator and Clock The cc2530 has an internal system clock, or a master clock. The system clock Source is a 16Mhz rc crystal oscillator or 32MHz crystal oscillator. The clock can be controlled using the Clkconcmd special function register. In addition, the chip als

1. In stm32, there are five clock sources:HSI,HSE,LSI,LSE,PLL. ①HSIIt is a high-speed internal clock, RC oscillator, and the frequency is 8 MHz. ②HSEIt is a high-speed external clock, which can be connected to a Z/Ceramic Resonator or an external clock source. The frequency range is 4 MHz ~ 16 MHz. Generally, it is con

The arm arch in kernel-2.6.22 has added support for dynticks, clocksource/event. We have found some recent changes to the kernel clock and timer subsystems.Generally, soft-timer (timer wheel/hrtimer) is composed of hardware-timer (such as clock interruption) and related clock source (E. g GPT in SOC) driver, so I plan to start from the

First, background:Recently, a project has been taken over, the core chip is both the LPC17XX series MCU, core arm of the COTEX-M3 core.If you want to play with an MCU, you have to take care of its clock!The clock is to the MCU, like the human heart. It gives the AHB, APB Bus The blood (clock frequency), and the devices that hang on the AHB (Advance High bus) bus

Study on auxiliary clock of AT91RM9200 Platform [Date:] Source: MCU and Embedded System Application Author: baili Ren nun, Lanzhou Jiao Tong University [Font:Large Medium Small] 　 IntroductionIn VxWorlks, the implementation of the timer mechanism is based on the clock. Different Timing mechanisms can be selected based on different requirements, such as taskDelay (), WatchDog, and auxili

Jitter is defined as the deviation of the signal from its ideal position. This article focuses on clock Jitter and discusses the following types of clock jitter: adjacent periodic jitter, periodic jitter, time interval error (TIE) jitter, phase noise, and phase jitter.Introduction to Clock JitterClock jitter is the deviation of the
