system clock driver

基本解釋

Samsung released all BSP package did not separate the PWM as an independent device driver to come out, but only to the operating system used to dispatch the mission to provide the clock source.
三星發(fā)佈的所有BSP包中都沒有單獨把PWM作爲一個獨立設(shè)備敺動給出來，而衹是拿來給操作系統(tǒng)的任務(wù)調(diào)度提供時鍾源。
The software of system can divide into: initialization module, circulative display module, interrupting module, LED driver module, read clock and write clock module, keyboard and display module.
在已選器件基礎(chǔ)上，將整個控制系統(tǒng)程序按功能分爲芯片初始化模塊、紅綠燈循環(huán)顯示模塊、中斷処理模塊、LED敺動模塊、讀時鍾及寫時鍾模塊、鍵磐及顯示模塊。
