Linux ARM開發板

一、項目背景

    SAM9260單板機是面向安全監控、儀器儀表、工業自動化行業等領域,推出的基于ATMEL AT91SAM9260處理器,預裝Linux2.6多任務操作系統,客戶可根據我們提供的編譯工具(GCC)進行系統功能進行添加、修改等操作和軟件開發,還可以在配套底板的設計基礎上快速地進行功能的調整,實現客戶的產品快速上市??蛻艨蓪BS-SAM9260作為一個遠端主控器,直接通過ADC或者通過串口連接下位機采集現場的各種模擬量、開關量等數據;采集到的數據可以通過CAN、以太網傳送至控制中心??刂浦行囊部赏ㄟ^CAN、以太網等方式控制SAM9260,并對之實現遠程更新程序及一系列工作。
