描述
為了讓嵌入式WinCE和多塊LPC935單片機(jī)進(jìn)行通信,關(guān)鍵是要有一個(gè)好的通信協(xié)議。包括對(duì)數(shù)據(jù)的形式、通信方式、傳送速度、傳送步驟、檢錯(cuò)方式以及控制字符定義等問(wèn)題做出統(tǒng)一規(guī)定[5].由硬件平臺(tái)的設(shè)計(jì)可以知道,每塊分板控制著4個(gè)比色池,每個(gè)比色池可以設(shè)定3個(gè)檢測(cè)通道,因此每塊分板可以控制12個(gè)檢測(cè)通道,并把它編號(hào)為1-12.但是每塊分板每次只能從每個(gè)比色池的3個(gè)通道中選著1個(gè)通道進(jìn)行檢測(cè),每次只能同時(shí)進(jìn)行4通道的檢測(cè)。整個(gè)系統(tǒng)可以同時(shí)進(jìn)行16通道的檢測(cè)。CAN通信報(bào)文傳輸?shù)膸袷接泻?1位標(biāo)識(shí)符的標(biāo)準(zhǔn)幀和含有29位標(biāo)識(shí)符的擴(kuò)展幀。本設(shè)計(jì)采用了標(biāo)準(zhǔn)幀的格式進(jìn)行CAN通信協(xié)議的設(shè)計(jì)。
