C-Mount Threaded Optical Component Adapters This page contains all of our Optical Component Thread Adapters that feature C-mount (1.00"-32) threading. Adapters featuring either internal or external threads are available. The CS- and C-mount standards both use 1.00"-32 threads, but C-mount lense...
RT-thread平台演示采用了我之前自己DIY的一块PLC开发板,外壳完全兼容西门子的S7-200的PLC外壳,主控这里采用国产的珠海半导体的APM32E103VET6芯片(基本兼容STM32F103VET6,引脚Pin2Pin兼容,但是RAM时STM32的2倍,128K,STM32只有64K,另外APM32的主频为120Mhz),网络部分采用W5500网络芯片。运行rt-thread系统。电路图和测试...

A7 processor is a very energy-efficient application processor designed to provide rich performance in high-end wearables, and other low-power embedded and consumer applications. It provides up to 20% more single thread performance than the Cortex-A5 and provides similar performance than the Cortex-...
which can be tightened by hand to secure the attached components. Additional locking rings can be purchased separately to limit the external thread depth of any C-Mount-threaded components. The use of multiple locking rings allows lens tubes to be locked independently, such as when using crossed...

pthread_join (pthread_t thread, void** threadreturn); 3.线程通信 线程互斥 互斥意味着“排它”,即两个线程不能同时进入被互斥保护的代码。Linux下可以通过pthread_mutex_t 定义互斥体机制完成多线程的互斥操作,该机制的作用是对某个需要互斥的部分,在进入时先得到互斥体,如果没有得到互斥体,表明互斥部分被其...
