描述
先有目標(biāo),再去定位。
學(xué)ARM,從硬件上講,一方面就是學(xué)習(xí)接口電路設(shè)計(jì),另一方面就是學(xué)習(xí)匯編和C語(yǔ)言的板級(jí)編程。如果從軟件上講,就是要學(xué)習(xí)基于ARM處理器的操作系統(tǒng)層面的驅(qū)動(dòng)、移植了。這些對(duì)于初學(xué)都來(lái)說(shuō)必須明確,要么從硬件著手開(kāi)始學(xué),要么從操作系統(tǒng)的熟悉到應(yīng)用開(kāi)始學(xué),但不管學(xué)什么,只要不是純的操作系統(tǒng)級(jí)以上基于API的應(yīng)用層的編程,硬件的寄存器類的東西還是要能看懂的,基于板級(jí)的匯編和C編程還是要會(huì)的。因此針對(duì)于嵌入式系統(tǒng)的硬件層和驅(qū)動(dòng)程的人,ARM的接口電路設(shè)計(jì)、ARM的C語(yǔ)言和匯編語(yǔ)言編程及調(diào)試開(kāi)發(fā)環(huán)境還是需要掌握的。
