对于实时嵌入式系统来说,最重要的是每一个进程所需时间的可检测性,可预测性.要不你的实时性是没有办法保证的.有些时候你对一些没有从事过嵌入式开发的人谈这个进程(TASK)设计是按8ms被调度一次,他们会觉得很奇怪.所以尽量避免一些不可预测的操作是非常重要的,比如说动态内存分配等. 我这次就遇到一个问题,Panel那边由于重新设计,给一个子模块的发送的数据的速度提高很多,造成子模块没有能力去执行Panel发过来的指令.从示波器很明显的可以看出,Panel发了8个命令,但是子模块只能处理一个命令.…

蓝牙一词源于公元十世纪丹麦国王HaraldBlatand名字中的Blatand.Blatand的英文之意就是Blue tooth.这是因为这位让丹麦人引以为傲的国王酷爱吃蓝莓以至于牙龈都被染成蓝色.由于Blatand统一了丹麦和挪威,所以,作为无线通信技术的一种,蓝牙技术之所以取名Bluetooth可谓志向远大.不过,在以Android为代表的智能机出现以前,蓝牙在早期智能机甚至功能机中一直扮演着“鸡肋”的角色.那么,随着无线通信技术的快速发展以及Android的普及,蓝牙能给我们带来哪些新的变…
