Hello everyone, I am Chris, the field application engineer from Nuvoton Technology. Today I will introduce the power modes of the M251/M252 series microcontroller. The M251/M252 series has multiple power modes. The differentiation is based on power consumption, wake-up time, the operable CPU, and peripherals. In normal mode, the CPU is running normally. In Idle mode, only the CPU clock is disabled while other peripherals work as usual. Normal mode and idle mode can be divided into high-efficiency high-speed PL0 mode and low-power low-speed PL3 mode according to CPU operating speed. We should note that in the low-speed PL3 mode, only the clock source of the CPU and peripherals is 32.768 or 38.4 kHz can run. In power-down mode, there are three types according to power consumption. The first is NPD (Normal Power Down Mode). The CPU and high-speed peripherals stop running, and only the low-speed peripherals can work normally. The second is FWPD (Fast Wake Up Power Down Mode), which is the fastest wake-up of the three power-down modes but consumes more power. The third is DPD (Deep Power Down Mode), which consumes the lowest power among the three power-down modes, but the data in the RAM cannot be retained, and the wake-up speed is the slowest. Specific peripherals or pins can only activate the wake-up. For power consumption and wake-up time, we list the corresponding data. Users can choose the most suitable power mode according to the required power consumption and wake-up time. We need to note that FWPD mode will consume more power in the power-down mode because this mode wakes up the fastest. The DPD mode is the least power consumption, but the longest wake-up time.， Also, normal mode is a normal working mode, so there is no need to wake up. The time unit of the idle mode is different from the power-down mode, which is five cycles. The length of a cycle is determined according to the operating frequency used by the system. In the related resources section, we provide application notes for power management, which have more detailed operations and descriptions. If you want to know more, please download it from the URL in the video. There are also various power mode entry and wake-up methods in the BSP package; you can also refer to and use it. That’s all for the power modes introduction. Thank you for watching it. Please subscribe to our channel for more video resources.

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. In the system upgrade, Nu-Link2-Pro also provides five standard communication interfaces such as SPI, I2C, UART, RS485, and CAN for transmission, which is convenient for users to upgrade the system. That’s all for the introduction of Nuvoton’s programming and debugging tool, NuLink-Gang, and NuLink2-Pro. Thank you for watching it. If you want to know more details, please contact us! Thank you. #Tool #Training #Learning #Intermediate #en - For more information, please visit Nuvoton Technology Website: https://bit.ly/3hVdcmC Buy now: https://direct.nuvoton.com/numaker-m251sd Contact us: SalesSupport@nuvoton.com

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 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.
