  • GM814x兼容SPITM總線的UART擴(kuò)展芯片并聯(lián)擴(kuò)展應(yīng)用

    1 概述由于在某些通訊設(shè)計應(yīng)用中，需要擴(kuò)展更多的串口數(shù)量，比如車床監(jiān)控、紡織儀器檢測和網(wǎng)狀連接的數(shù)據(jù)采集等應(yīng)用。為此成都國騰微電子有限公司推出的GM814x 可以滿足多個同類產(chǎn)品的并聯(lián)擴(kuò)展，并且能簡單的實現(xiàn)電路連接和程序控制，主MCU 可以識別數(shù)據(jù)的來源和指定和某個GM814x 通信。2 應(yīng)用說明2.1 CS 與SPI 的數(shù)據(jù)通信GM814x 的CS（片選）引腳可用于控制SPI 總線時鐘有效性，CS 低電平有效，內(nèi)部下拉。CS 有效時，允許芯片的時鐘接收和數(shù)據(jù)收發(fā)；無效時，SCLK、DIN 和DOUT 均為高阻狀態(tài)，GM814x 不響應(yīng)SPI 上的數(shù)據(jù)收發(fā)，但能正常收發(fā)子串口數(shù)據(jù)和產(chǎn)生相應(yīng)中斷。2.2 應(yīng)用建議當(dāng)使用GM814x 的應(yīng)用需要擴(kuò)展4 個以上的串口數(shù)量時，就需要使用2 片以上的GM814x。擴(kuò)展的方式也有多種。方式一：將多個GM814x 的SPI 接口接在主MCU 的SPI 總線上，然后將所有GM814x 的中斷進(jìn)行線與后連接到MCU 的IRQ 上，同時將各GM814x 的IRQ 輸出又連接到MCU的IO，以便MCU響應(yīng)中斷后檢測是具體哪一個GM814x 輸出的中斷，然后再拉低對應(yīng)的CS，拉高其它GM814x的CS，并執(zhí)行通信操作。方式二：如果擴(kuò)展的GM814x 數(shù)量較多，采用上述擴(kuò)展方式可能會占用MCU較多的IO 資源，則可以將GM814x 的中斷輸出連接到具有OC 輸出的與門芯片上，再輸出到MCU 的中斷輸入。同時又將所有的GM814x 的中斷輸出進(jìn)行編碼輸入到MCU，以供其判斷產(chǎn)生中斷的是哪一個GM814x。方式三：將所有GM814x 的中斷輸出連接到優(yōu)先編碼器進(jìn)行編碼輸出，同時編碼器也能輸出低電平信號給MCU 作為中斷響應(yīng)。MCU 檢測編碼數(shù)據(jù)以獲知產(chǎn)生中斷的GM814x，然后進(jìn)行數(shù)據(jù)通信處理。這種方式電路最簡單，占用MCU 的IO 資源也最少。 舉例：使用MCS51 單片機(jī)擴(kuò)展8 片GM814x。本電路中，采用了上述提到的第三種擴(kuò)展方式。通過普通的MCS51 單片機(jī)擴(kuò)展最多8 片GM814x，可擴(kuò)展最多32 個標(biāo)準(zhǔn)串口。為了節(jié)省MCU的IO 資源，電路中增加了一片8-3 線優(yōu)先編碼器74LS348 和一片3-8 線譯碼器74HC138。8 片GM814x 的IRQ 中斷通過一片74LS348 輸出中斷源向量，同時產(chǎn)生GS 低電平信號到MCS51 的外部中斷0 上，MCS51 響應(yīng)中斷后，可查詢A0~A2 的值確定產(chǎn)生中斷的GM814x，然后MCU 使能74HC138，輸出對應(yīng)的ABC 信號選中產(chǎn)生IRQ 信號的GM814x，再進(jìn)行SPI 總線上的數(shù)據(jù)通信。 示例程序：本示例程序使用C 語言描述，僅供參考。 由于74LS348 是優(yōu)先編碼器，多個中斷同時產(chǎn)生的時候，74LS348 的編碼只會指示輸入編號上最高的IRQ，MCU 無法直接獲知是否其它的GM814x 也產(chǎn)生了中斷。同時GM814x 在自己的中斷申請后，數(shù)據(jù)傳輸?shù)降?bit 時會自動清除，所以數(shù)據(jù)接收完后如果MCU 的中斷引腳仍然為低，則表示還有其它GM814x 的中斷申請，故必須在處理完當(dāng)前中斷后繼續(xù)查詢新的中斷向量。這就是上述示例程序中while 循環(huán)的目的。 以上應(yīng)用建議僅供設(shè)計者參考，不代表最終實現(xiàn)方式，更可靠和實際的實現(xiàn)方式可由設(shè)計者根據(jù)自己的實際情況確定。l 示例中的數(shù)據(jù)、參數(shù)和標(biāo)志字命名不代表實際產(chǎn)品的特性，請參考實際產(chǎn)品的數(shù)據(jù)手冊來獲取你所需要的數(shù)據(jù)。
