Hello everyone I am Chris, the Field Application Engineer from Nuvoton Technology. Today I will introduce the programming and debugging tool, called NuLink-Gang, and NuLink2-Pro. And I will show you in what kind of situation you can utilize the tools. During system development, Nuvoton provides three IDE interfaces: KEIL, IAR, and NuEclipse for user to develop source code. When programming the Chip, Nuvoton provides ICP programming Tool in PC and the debugger Nu-Link2-Pro for users to perform debugging and programming function. User who uses all of the Nuvoton Nu-Maker boards series can develop through the Nu-Link2-Me debugger and programmer; it’s attached to the board. During the mass-production stage, there are 2 modes for programming the target chip. One is online programming and the other is offline programming. At first, in online programming mode, user can use ICP programming Tool and a Nu-Link2-Pro to program a target chip. Besides, if it needs to program several chips at one times, the Nu-Link Command Tool supports program multiple develop board by several Nu-Link2-Pro. Nu-Link2-Pro also supports drag-and-drop Flash programming. User can intuitively complete the programming action. Nu-Link2-Pro In offline programming mode, user can pre-store the programming file in SPI flash, USB flash drive, or SD card. When user wants to program the target chip, pressing the programming button on Nu-Link2-Pro to complete the programming action. If it needs a large number of ICs to be programming, it recommends using the Nu-Link-Gang programmer. Nu-Link-Gang programmer can perform offline programming on four different chips at a time, significantly increasing the programming efficiency. Besides, Nu-Link-Gang programmer can also use the control bus to connect with an automatic programming machine for automatic programming.

Hello everyone! I am Chris, the Field Application Engineer from Nuvoton Technology. Today, I will introduce how to run a simple sample code on NuMicro M251/M252 series microcontroller. First, we connect the M251/M252 NuMaker development Board to the computer. Then click the M251/M252 BSP folder, click the Sample Code folder, template folder, Keil folder, and finally open the Template project file. What we are going to do is running a simple GPIO Toggle LED Sample Code. Introduce the main program briefly. First, set GPIO PB14 to Output Mode. After writing a small loop, set PB14 to reverse. Finally, set CLK_SysTickDelay to 300,000 microseconds (uSec). Before Rebuild, we must add the GPIO Source Code to the Library, find the corresponding Source Code and load it, and press Rebuild after it is complete. After the Rebuild, press Load and program the Code into the IC. When programing is over, press the reset button on the development board to confirm whether the LED lights are flashing on the board. That’s all for the tutorial of running sample code. Thank you for watching it.

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.

Open Chrome browser, and enter the URL https://ide.mbed.com to use the Mbed Online Compiler. After log in, make sure that NuMaker-IoT-M487 board already selected in the upper right corner. If not, please refer Nuvoton IoT Tutorial series “Get Started with Mbed OS” which has a detailed description of how to add a board. Click the “New” on the left of menu bar, a “Create new program” window will be displayed. You can see that the Platform has been set to NuMaker-IoT-M487. In the Template, select the "NuMaker audio playback" for this tutorial. Then click OK. Now you can see that the sample code has loaded on the page. The sample code has three functions: 1. Record 10 seconds sound and save to Micro SD card 2. Play sounds stored in Micro SD card 3. Loopback. Record sound and play it immediately. Click main.cpp to open it. Then scroll down to line 421. You can see the functions calls here. It set to loopback only. Let’s do a little modification. Hit a key on console to start record 10 seconds then play it, and then do loopback. printf("Press a key to start recording 10 seconds..."); getchar(); demo_record(); demo_play(); demo_loopback(); Save it and click “Compile” to build the code. Compilation takes a while, please wait. After the compilation is completed, “Success” will appear in the compile output window. The browser downloads the binary firmware file directly after a successful compiling. It will be saved in a default download folder. In Chrome, you can click download file and select “Show in folder”. Please plug an earphone commonly used for mobile phone in headphone jack on NuMaker-IoT-M487 board. For demonstration, we use a headphone splitter cable to connect a microphone and a speaker. Do not put the microphone and speaker too close to avoid feedback howling. Then connect the USB port to your computer and make sure the onboard LED lights up. Back to the folder you just download the binary firmware file (NuMaker-mbed-AudioPlayback-example.NUMAKER_IOT_M487.bin). Drag and drop the file to NuMicro MCU drive. You will see the copying progress dialog box. Please find the virtual COM port assigned for NuMaker-IoT-M487 in Device Manager. In the demonstration, the “Nu-Link Virtual Com Port” is COMx. Then use your favorite terminal tool. Here we use Putty. Open the COMx port with 9600 baud rate. And no flow control settings. Then “Open” it. Press “Reset” on board to run the firmware again. Press a key on terminal to start record. Speak for about 10 seconds, then your voice will be played. That’s all for this tutorial. Thank you for watching. Welcome to subscribe to our channel.

Hello everyone, I am Morgan, the principal engineer of Nuvoton Technology. Today, I will show you how to use SD card with Mbed OS on NuMaker-IoT-M487 development board. Open Chrome browser, and enter the URL https://ide.mbed.com to use the Mbed Online Compiler. After log in, make sure that NuMaker-IoT-M487 board already selected in the upper right corner. If not, please refer Nuvoton IoT Tutorial series “Get Started with Mbed OS” which has a detailed description of how to add a board. Click the “New” on the left of menu bar, a “Create new program” window will be displayed. You can see that the Platform has been set to NuMaker-IoT-M487. In the Template, select the "NuMaker SD-File-System with SD mode" for this tutorial. Then click OK. Now you can see that the sample code has loaded on the page. LittleFS uses less memory, supports power failure protection. However, LittleFS is different from the FAT file system, so after uses littleFS, the SD card will be formatted as LittleFS. The sample code uses FAT file system as default. Just click “Compiler” to build the example. It is in compiling, please wait a moment. After the compilation is complete, “Success” will appear in the compile output window. The browser downloads the binary firmware file directly after a successful compiling. It will be saved in a default download folder or the folder based on your browser setting. In Chrome, you can click download file and select “Show in folder”. Please insert a micro SD card into the card slot on the back of NuMaker-IoT-M487 board, then connect the USB to your computer and make sure the onboard LED lights up. Let’s back to the folder you just download the binary firmware file (NuMaker-mbed-SD-FileSystem-example.NUMAKER_IOT_M487.bin). Drag and drop the file to NuMicro MCU drive. You will see the copying progress dialog box. Please find the virtual COM port assigned for NuMaker-IoT-M487 in Device Manager. In the demonstration, the “Nu-Link Virtual Com Port” is COMx. Then use your favorite terminal tool. Here we use Putty. Open the COMx port with 115200 baud rate And no flow control settings. Then “Open” it. Press “Reset” on board to run the firmware again. You can see the messages on terminal while accessing SD card. That’s all for this tutorial. Thank you for watching. Welcome to subscribe to our channel.
