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)布的所有BSP包中都沒有單獨把PWM作為一個獨立設(shè)備驅(qū)動給出來，而只是拿來給操作系統(tǒng)的任務(wù)調(diào)度提供時鐘源。
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)程序按功能分為芯片初始化模塊、紅綠燈循環(huán)顯示模塊、中斷處理模塊、LED驅(qū)動模塊、讀時鐘及寫時鐘模塊、鍵盤及顯示模塊。
