      【躍昉科技BF2開發(fā)板試用體驗(yàn)】躍昉BF2物聯(lián)網(wǎng)開發(fā)板試用體驗(yàn)

      開發(fā)板試用精選 ? 來源：開發(fā)板試用 ? 作者：電子發(fā)燒友論壇 ? 2022-11-09 16:12 ? 次閱讀

      本文來源電子發(fā)燒友社區(qū)，作者：Aivisus， 帖子地址：https://bbs.elecfans.com/jishu_2293431_1_1.html

      通過電子發(fā)燒友論壇的試用申請(qǐng)，拿到了這款躍昉BF2物聯(lián)網(wǎng)開發(fā)模塊，模塊比預(yù)想的要小很多，尺寸在一寸多點(diǎn)。但別看他小，它可是五臟俱全。把它與 IV18 熒光管放一起對(duì)比一下，就看出來了，它的體積是非常迷你的了。

      官方對(duì)BF2的模塊介紹是這樣的，BF2開發(fā)板包含以下組件：LF-WM03模塊、I/O口、JP短接口、State led狀態(tài)指示燈、Power led電源指示燈、RST復(fù)位按鍵、MiniUSB口、Power selected電源選擇口、四線插座、USB-to-UART橋接器、Data transfer selected傳輸選擇。主要是面向智慧能源、智慧物流、智慧城市、智慧工廠等工業(yè)物聯(lián)網(wǎng)應(yīng)用，是一款基于RISC-V架構(gòu)的邊緣智能處理器產(chǎn)品

      這里介紹一下 IV18這個(gè)熒光管，IV-18(ИВ-18)熒光電子數(shù)碼管，是上世紀(jì)80-90年代前蘇聯(lián)的產(chǎn)物，冷戰(zhàn)時(shí)期曾大量制造并用于軍事設(shè)備；它是一根管內(nèi)嵌入了8個(gè)7段數(shù)字，并且每個(gè)數(shù)字右下角都有小數(shù)點(diǎn)，在管子的左側(cè)，還有一個(gè)表示負(fù)數(shù)的短橫線，在短橫線上面還有一個(gè)較大的圓點(diǎn)符號(hào)。驅(qū)動(dòng)它的整個(gè)電路由升壓電路、MCU主控、RTC模塊、VFD驅(qū)動(dòng)、外圍及接口器件這幾部分組成。升壓電路部分使用的還是廉價(jià)并經(jīng)典的MC34063做高壓升壓，外擴(kuò)了MOS管IRLR024，升壓效率大幅提高，而且MC34063、電感、MOS管一點(diǎn)也感覺不到溫度；IV-18的推薦工作電壓為45v-70v，工作在49v的時(shí)候效果最佳。

      因?yàn)镮V18熒光管模塊帶有 溫度，濕度，環(huán)境亮度的傳感器，但其不具有網(wǎng)絡(luò)功能，因此想利用 BF的物聯(lián)網(wǎng)功能，將 IV18改造成為一款物聯(lián)網(wǎng)時(shí)鐘，主要改造的目的是：

      1、把IV18物聯(lián)網(wǎng)模塊的傳感數(shù)據(jù)通過物聯(lián)網(wǎng)協(xié)議傳輸?shù)轿锫?lián)網(wǎng)平臺(tái)上，以便實(shí)時(shí)記錄環(huán)境的監(jiān)測(cè)數(shù)據(jù)

      2.、能夠?qū)r(shí)鐘模塊進(jìn)行自動(dòng)的校時(shí)，以便讓時(shí)鐘模塊運(yùn)行更加準(zhǔn)確

      這兩個(gè)模塊它們放在一起是這樣的：

      image.png

      根據(jù)IV18 MCU的電路圖，IV18時(shí)鐘模塊使用的是STC12C56的8位單片機(jī)驅(qū)動(dòng)，C51的代碼開發(fā)。這里通過串口連接兩個(gè)模塊，達(dá)到數(shù)據(jù)雙向通訊和控制的目的。

      這里通過BF2的P12,14 的UART0 與 STC12c56的P3.1,P3.0 相連即可，需要注意的是，STC處理器的工作電壓是5V, 按理需要對(duì)STC的IO進(jìn)行分壓后，再與BF2連接，但在實(shí)際測(cè)試中，直接連接也可以工作，因此就簡(jiǎn)化處理，直接連接上了。

      image.png

      硬件連接很簡(jiǎn)單，硬件連接完后，主要的工作是軟件開發(fā)，分別開發(fā)C51代碼與BF2模塊上的代碼。

      這里把 BF2當(dāng)成STC單片機(jī)的上位機(jī)即可，完成數(shù)據(jù)收發(fā)與命令的接收控制邏輯。

      C51的開發(fā)比較簡(jiǎn)單，不多說，主要的代碼如下：

      BF2的開發(fā)，主要按開發(fā)板所帶的開發(fā)資料來進(jìn)行，BF2開發(fā)板帶科豐富的開發(fā)資料，需要仔細(xì)的看一下，主要開發(fā)指導(dǎo)文件在，《BF2 SDK入門指南》主要介紹快速了解SDK的使用，

      BF2開發(fā)資料有：

      SPEC 目錄，主要是開發(fā)板，芯片規(guī)格書以及SDK 文檔資料

      SDK 主要是SDK軟件，編譯工具鏈以及例程

      Dev_tools 是一些下載工具

      SDK里主要的內(nèi)容有：

      Component： SDK提供的組件

      Customer_App:SDK提供的DEMO，開發(fā)主要參考這些demo代碼來完成

      Docs: 即文檔目錄，所有SDK的庫，函數(shù)的說明，以及編譯工具的配置，說明

      Make_script_riscv 編譯相關(guān)腳本

      Toolchain : 編譯工具鏈

      tools 燒寫工具

      在BF2的SDK里提供了三種平臺(tái)的開發(fā)環(huán)境，分別是 Darwin, Linux , MySYS

      這里我選用的是 Linux的開發(fā)環(huán)境，搭建Linux開發(fā)環(huán)境方法如下：

      1.在Linux 下建立一個(gè)主工作目錄，也可以創(chuàng)建一個(gè) DOCK,在DOCK中操作

      1. 將BF2提供的 riscv.rar 文件解壓開，把其中的 Linux 目錄復(fù)制到 Linux 下 。

      3 將SDK里的 lf_iot_sdk 和 components 整個(gè)目錄復(fù)制到工作目錄下

      3.配置環(huán)境變量，分別把 riscv 的SDK頭文件主目錄和連接的庫文件目錄放入環(huán)境變量中

      1. 在Linux 下執(zhí)行編譯命令，編譯一個(gè)測(cè)試文件， 測(cè)試開發(fā)環(huán)境創(chuàng)建正確，在Linux下可以看到編譯器的版本如下

      image.png

      建立編譯環(huán)境完成后，下一步進(jìn)行響應(yīng)的代碼的開發(fā)，這次主要參考了SDK Customer_app 的三個(gè)主要DEMO工程，分別是：

      sdk_app_uart_ctl

      sdk_at_module

      lf686_gate_demo

      他們分別是串口通信功能的實(shí)現(xiàn)，串口命令的的開發(fā)，以及 IOT 網(wǎng)關(guān)的實(shí)現(xiàn)代碼，以便使用 MQTT 物聯(lián)網(wǎng)協(xié)議，將傳感數(shù)據(jù)傳送到案例物聯(lián)網(wǎng)平臺(tái)上。
