hex文件里面只有00，01，04三種碼。那么我們?cè)诮馕龅臅r(shí)候只需要對(duì)這三種不同狀態(tài)的進(jìn)行不同的解析即可。

hex文件格式的解析，可閱讀：HEX文件格式詳解

首先創(chuàng)建一個(gè)Block的結(jié)構(gòu)體，根據(jù)經(jīng)驗(yàn)我們知道，一個(gè)數(shù)據(jù)塊有：開(kāi)始的地址，數(shù)據(jù)的長(zhǎng)度，以及數(shù)據(jù)Buffer。三個(gè)結(jié)果。而一個(gè)hex文件里面可能有多個(gè)數(shù)據(jù)塊，因此我們接下來(lái)聲明了5個(gè)數(shù)據(jù)塊。這個(gè)需要根據(jù)變量進(jìn)行調(diào)整。然后根據(jù)hex文件初始化數(shù)據(jù)塊的個(gè)數(shù)。再聲明變量 HexBlockTotalNumber 為數(shù)據(jù)塊的總數(shù)。
