M8電源：如果想擴流使用，需要多個功率管并聯(lián)，必須加均流電阻。并且同時要增加主濾波和泄放電阻。功率管多需要增加一級推動管。 液晶的連接圖。【注意1腳位置】 液晶的背光接法：從液晶背后標記A和K的位置引出背光電源，接到M8V4電源板上標記LED的位置。注意有正負，反了背光不亮。 首次通電，需要調整液晶對比度才能顯示，調整M8V4電源板上的5K可調。讓顯示清晰即可。

帶中文字庫的128X64是一種具有4位/8位并行、2線或3線串行多種接口方式，內部含有國標一級、二級簡體中文字庫的點陣圖形液晶顯示模塊；其顯示分辨率為128×64, 內置8192個16*16點漢字，和128個16*8點ASCII字符集.利用該模塊靈活的接口方式和簡單、方便的操作指令，可構成全中文人機交互圖形界面。可以顯示8×4行16×16點陣的漢字. 也可完成圖形顯示.低電壓低功耗是其又一顯著特點。由該模塊構成的液晶顯示方案與同類型的圖形點陣液晶顯示模塊相比，不論硬件電路結構或顯示程序都要簡潔得多，且該模塊的價格也略低于相同點陣的圖形液晶模塊。 基本特性: 低電源電壓（VDD:+3.0--+5.5V） 顯示分辨率:128×64點 內置漢字字庫，提供8192個16×16點陣漢字(簡繁體可選) 內置 128個16×8點陣字符 2MHZ時鐘頻率 顯示方式：STN、半透、正顯 驅動方式：1/32DUTY，1/5BIAS 視角方向：6點 背光方式：側部高亮白色LED，功耗僅為普通LED的1/5—1/10 通訊方式：串行、并口可選 內置DC-DC轉換電路，無需外加負壓 無需片選信號，簡化軟件設計 工作溫度: 0℃ - +55℃ ,存儲溫度: -20℃ - +60℃ 12864（帶字庫漢字顯示演示程序）

Study-3 51單片機開發(fā)板原理圖:1-單片機的管腳除下載的幾個（P30,P31,P15,P16,P17,RST）之外，均直接擴展出來，原理圖中對應綠色的網(wǎng)絡2-紅色的網(wǎng)路對應的是這個板子上的外設，比如 液晶 數(shù)碼管等等3-其他顏色的就是對應的各個部分的網(wǎng)絡4-這個原理圖的布局是根據(jù)PCB的布局來設計的，這樣方便查閱5-在PCB中的右面擴展出來的萬能板上，外面的一排是GND，里面的一排是VCC，擴展的時候，可以把電源直接接到這里就可以了6-板子的左上角有2個跳線，一個是控制液晶的背光用的，一個是2位數(shù)碼管的能信號，因為采用了74ls164串轉并的方案，所以數(shù)碼管和串口不能同時使用，但是下載程序不影響，即平時短接就可以當作串口試驗的時候，建議把跳線斷開7-關于S系列單片機的使用，這個板子兼容S系列的單片機使用，留有下載線的接口8-下載程序說明，STC單片機采用串口下載，下載前一定要冷啟動即斷電，點擊下載，上電，程序就會下載進去了

摘要: 串行傳輸技術具有更高的傳輸速率和更低的設計成本, 已成為業(yè)界首選, 被廣泛應用于高速通信領域。提出了一種新的高速串行傳輸接口的設計方案, 改進了Aurora 協(xié)議數(shù)據(jù)幀格式定義的弊端, 并采用高速串行收發(fā)器Rocket I/O, 實現(xiàn)數(shù)據(jù)率為2.5 Gbps的高速串行傳輸。關鍵詞: 高速串行傳輸; Rocket I/O; Aurora 協(xié)議 為促使FPGA 芯片與串行傳輸技術更好地結合以滿足市場需求, Xilinx 公司適時推出了內嵌高速串行收發(fā)器RocketI/O 的Virtex II Pro 系列FPGA 和可升級的小型鏈路層協(xié)議———Aurora 協(xié)議。Rocket I/O支持從622 Mbps 至3.125 Gbps的全雙工傳輸速率, 還具有8 B/10 B 編解碼、時鐘生成及恢復等功能, 可以理想地適用于芯片之間或背板的高速串行數(shù)據(jù)傳輸。Aurora 協(xié)議是為專有上層協(xié)議或行業(yè)標準的上層協(xié)議提供透明接口的第一款串行互連協(xié)議, 可用于高速線性通路之間的點到點串行數(shù)據(jù)傳輸, 同時其可擴展的帶寬, 為系統(tǒng)設計人員提供了所需要的靈活性[4]。但該協(xié)議幀格式的定義存在弊端,會導致系統(tǒng)資源的浪費。本文提出的設計方案可以改進Aurora 協(xié)議的固有缺陷,提高系統(tǒng)性能, 實現(xiàn)數(shù)據(jù)率為2.5 Gbps 的高速串行傳輸, 具有良好的可行性和廣闊的應用前景。
