EXC-4000PCIe/xx card & M4KCAN module
對PCI Express總線的exc-4000pcie / XX卡最多支持二零四個CAN通道使用m4kcan模塊。每個通道包含256字節(jié)的雙端口RAM的數(shù)據(jù)塊和控制寄存器。所有數(shù)據(jù)塊和控制寄存器都是內(nèi)存映射的,并且可以實時訪問.。CAN協(xié)議使用一個多主(爭用)總線配置的網(wǎng)絡(luò)節(jié)點之間的“通信對象"的傳輸。這多主總線也稱為CSMA/Cr或載波偵聽多址接入,以解決沖突。m4kcan執(zhí)行所有的串口通信功能,如發(fā)送和接收消息,發(fā)送消息過濾,搜索,并中斷了與用戶的互動搜索最小。
m4kcan支持標(biāo)準(zhǔn)的和擴展的消息幀可以規(guī)范2部分B.它有能力發(fā)射、接收,并進行信息過濾的擴展消息幀29位標(biāo)識符的消息。
由于向后兼容CAN2.0B規(guī)范的性質(zhì),m4kcan也*支持標(biāo)準(zhǔn)消息幀11位標(biāo)識符的消息如能規(guī)范2部分A.
Exc-4000pcie / XX提供的C驅(qū)動程序,包括源代碼。為I/O連接提供的交配連接器。
請參閱多協(xié)議4000模塊的附加信息的協(xié)議,可以添加到這張卡。
