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 NUC980 IIoT 為平台，使用 Linux 進行開發，學習開發各式功能，觀看本片，您將學會如何控制 GPIO 使 LED 閃爍。 哈囉大家好，我是新唐工程師 Kevin，今天為大家介紹如何在 NuMaker NUC980 IIoT 板子上透過 GPIO 讓 LED 燈閃爍。 NuMaker NUC980 IIoT 板子的 Power-on Setting上方有 3 個 LED 燈，分別由不同的 GPIO 控制。最左邊，編號 LED03 的 LED 燈是由 GPIO B8 這根 pin 控制。今天示範如何用程式控制 GPIO B8 讓 LED 燈閃爍。 這是 LED 燈閃爍的程式，在看程式之前，我先為各位說明，在 Linux kernel 中，每一根 GPIO pin 都有編號。每一個 GPIO Group 占用 32個編號，編號為 0 到 31，分配給 GPIO Port A 這個 group，編號 32 到 63 分配給 GPIO Port B，以此類推。 LED03 這個 LED 燈是由 GPIO B8 這根 pin 控制，GPIO B8 在 Linux 中的編號是 40。 回到程式中，我們看到這個程式是透過 system function 執行系統命令，透過 Linux kernel 的 sysfs 控制 GPIO。 第 23 行 system("echo40 /sys/class/gpio/export"); 是將 GPIO B8 設定成可以用sysfs 控制。 第 24 行 system("echo out /sys/class/gpio/gpio40/direction"); 是將 GPIO B8 設定為 output。 接下來在 while loop 中，透過 system("echo 1/sys/class/gpio/gpio40/value"); 讓 GPIO B8 輸出 high；再透過 system("echo 0 /sys/class/gpio/gpio40/value"); 讓 GPIO B8 輸出 low，中間延遲 1 秒鐘，就可以做到 LED 燈閃爍的功能。 這個程式，main.c，儲存後，進行 compile 輸入 arm-linux-gcc main.c -o gpio_toggle (輸入 ls) 產生一個執行檔 gpio_toggle 將 gpio_toggle 拷貝到 root file system 目錄中， (輸入 sudo cp gpio_toggle ../rootfs) 然後重新 compile Linux Kernel 透過 NuWriter 將 Linux kernel 下載到NuMaker NUC980 IIoT 板子上執行 Linux Kernel 開機完成後，輸入 ./gpio_toggle，執行閃爍 LED 的程式。 此時可以看到 NuMaker NUC980 IIoT 板子上的 LED 正在閃爍。 - 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-nuc980-iiot 聯絡我們： SalesSupport@nuvoton.com
