Hello everyone, I am Chris, the field application engineer from Nuvoton Technology. Today, I will introduce the application and principle of programmable seriel I/O aka PSIO on M251/M252. The programmable serial I/O of NuMicro M251/M252 series can generate arbitrary waveforms and combine them to achieve data transmission and reception of specific serial communication protocols. Of course, standard serial communication can also be achieved, such as UART SPI I2C Usually, it is common to use Timer+GPIO to achieve these specific communication protocols, but it is more complicated and requires frequent CPU intervention. When we use PSIO, this not only simplifies the complexity of the operation but also reduces the burden on the CPU. The saved CPU performance could be distributed in other places. Since all hardware operations do not require software intervention, the timing control is more precise. The principle of PSIO is to use a slot controller to control the pin input and output or determine the state, and it can also control the duration of these states. Each slot controller has eight slots, which can be used as eight settings, and the registers corresponding to each slot can access the data that needs to be input and output, and can also set the time for the current pin to maintain this state. Each slot can reach a checkpoint, usually 1 to 1, 2 to 2, 3 to 3, and so on. Each checkpoint can set the pin status of the corresponding slot within the corresponding time. Next, let’s take a look at a simple output-only example In the initial stage, we first set the state of the pin to be high before SLOT has started, so the output is high Then when the Slot controller receives the start signal, SLOT0 is set to output low level according to the setting of CP0 and waits for the time of SLOT0 to expire. Then SLOT1 is set to output low level according to the setting of CP1 and waits for the time of SLOT1 to expire. And so on, followed by SLOT2 output low level SLOT3 low level SLOT4 high level SLOT5 high level After SLOT5, since SLOT6 is not set, the waveform of the protocol can be completed with only six slots Between the time of the next data transmission, we set the interval low, so the output is low at this time Users can complete different protocols according to these simple operations. In the related resources section, we have provided two PSIO application notes. There are two protocol examples with more detailed operations and descriptions. If you want to know more details about PSIO, please download it from the URL in the video. Several sample codes of different protocols are also provided in BSP. That’s all for this tutorial.

以新唐 NuMaker-IoT-M487 為平台，使用 Mbed OS 進行開發，學習各種功能。觀看本片，您將學會使用 NuMaker-IoT-M487 開發板配合 Mbed OS 與 Pelion 的範例程式連接 Pelion。 哈囉大家好，我是新唐工程師 Miya，今天為大家介紹如何使用新唐 NuMaker IoT-M487 在 MbedOS 跟 Pelion 上連接雲端。 因為憑證下載需求，所以操作前請先準備好一張 Format 好的 MicoSD Card 待用。 打開 Chrome 瀏覽器輸入網址"https://cloud.mbed.com/quick-start" 需要先啟動免費帳號，點選中間上方”Activate your free access” 後，下一個頁面點 Log in 登入您的帳號密碼，Log in。 啟動後，選擇中間選項"Start the Connect Tutorial"，系統會自動轉到這個頁面，往下拉選取 NuMaker-IoT-M487 (WiFi)。 選好後，點"Get started"，系統將導入此頁面，點選 1.2，將 pelion-example-common example 加進線上編譯平台。 確認系統匯入 pelion-example-common 後，點 Import。 Load code 中，請稍待片刻。 先點選"pelion-example-common program."，接著在 Online compiler IDE 環境的 menu bar 上，到 Pelion Device Management 中下拉選取"Manage Connect Certificates"來建立 Pelion 憑證。 API Key 這邊按一下 OK。 點"Create"，輸入您想存的連接憑證名字，之後按 OK。 點一下您建立的憑證，再按 OK，OK。 點 Pelion Device Management 選取"Apply Update Certificate."會出現 Update Certificates 視窗，按 Create，點"Download Private Key"。 接著先確認右上方板子已經有帶出”NuMaker-IoT-M487 及板子小圖示”了，如果沒有可參考教學影片”step by step 讓你了解如何運行 Mbed OS”，裡面有詳細的示範怎麼新增板子的方法！ 由於要使用 Wi-Fi，所以需要將 SSID 及密碼改成可符合您連線環境的設定。 找到 mbed_app.json 裡面 SSID 設定"wifi-ssid"，此版 sample code 在第 9 行，更改為您使用無線網路所設定的 SSID (我使用的是 nu)，接著再找到"wifi-password"設定，此版在第 10 行裡的 Password 改成您無線網路連接設定的密碼，改好後存檔，Compile，現在 Compile 中，需要等待一下，完成後看到最下方會秀出"Success!"。 系統會把 compile 完成的 bin 檔放在 download 資料夾， 直接從下方進入，上拉後，點一下”Show in folder”。 接著需要先把 format 過的 Micro SD Card 插入卡槽，再將 NuMaker-IoT-M487 板子跟 PC 接上 USB，確認板子有亮燈就是通電了。 回到剛才的資料夾，可以看到多了一個剛才 compile 完成的 bin 檔，按右鍵傳送到 NuMicro MCU(E:) 這邊分配到哪一槽要看各位的電腦決定！有成功點選到的話會出現傳送過去的畫面。 接著到電腦的裝置管理員查看分配到的 port 編號，在本機按右鍵，選管理，找到裝置管理員，到連接埠(COM 和 LPT) 可以看到 USB 序列裝置，就知道這部 PC 分配給它的是 COM9。 接下來使用終端機模擬軟體，各位可以用自己熟悉的軟體操作即可，設定 Serial line 為 COM9, Speed 為 115200，到 Serial 將 Flow control 改為 None，接著 OPEN。 設定好之後，在板子上按一次 reset，接著在終端機摸擬軟體就可以看到目前板子已經成功連接無線網路，看到雲端回傳的 Endpoint name 就代表連接成功囉！ 以上是這次的教學影片，感謝您的收看。歡迎訂閱我們的頻道。 如果您想知道更多資訊歡迎聯絡我們！ - 更多產品資訊，請至新唐科技網站 https://bit.ly/3hVdcmC 購買管道：https://direct.nuvoton.com/tw/numaker-iot-m487 聯絡我們： SalesSupport@nuvoton.com #Tool #Training #Learning #Intermediate #zh-Hant
