代码说明:

点亮LED灯 整篇文章的结构如下: 一、直接把时钟管理用到的寄存器罗列出来进行分析。 二、对其中的一些原理性的东西做介绍。 三、对于在后面编写串口时会出现的问题注意点提出说明。 四、LED 代码     一、在时钟管理中会用到的寄存器有以下一些。 LOCKTIME,MPLLCON,UPLLCON,CLKCON,CLKSLOW,CLKDIVN,CAMDIVN。 LOCKTIME:是对于配置好锁相环之后需要延时的一段时间,这时为了上锁稳定。其中包括两部分 ①U_LTIME:这是UCLK(USB专用的一个时钟)配置好后需要的延时时间。 ②M_LTIME:这时FCLK(系统时钟即CPU的频率),HCLK(一些高速设备所用到时钟),PCLK(低速设备所用到的时钟)这

  • px4飞控程序
    应用背景px4程序可以运行固定翼,旋翼等飞行器,而且是很多人再开发,有很多有用的算法,如扩展卡尔曼滤波,迭代法等等。可以GPS定位,GPS下走航点等等,希望能帮到大家关键技术C++编程,扩展卡尔曼滤波,IIC读取超声波,读取气压计。室外光流能很好定位,能用于固定翼,旋翼,而且可以二次开发,支持offboard模式。

  • CANopennode stm32 ds301
    应用背景CANopenNode is an opensource CANopen Stack. CANopen is the internationally standardized (EN 50325-4) CAN-based higher-layer protocol for embedded control system. For more information on CANopen see http://www.can-cia.org/ Stack is written in ANSI C in object-oriented way. Code is documented. License is LGPL. It includes Example for CANopen Input/Output device and simple CANopen master. Variables (communication, device, custom) are ordered in CANopen object dictionary and are accessible from both: C code and from CAN network. Code includes:  - CANopen Stack for multiple microcontrollers with documenation.  - Working examples of simple Input Output CANopen device for all microcontrolers.  - Working CANopen master device with HTML interface to CANopen: CAN log, Emergency log, SDO master, NMT master, Custom CAN message.
