  • NuMicro M251/M252 Series (2) Technical Features - Programmable Serial I/O (PSIO)
    トレーニング  こうぐ  学ぶ  ビデオの長さ - 5:9
    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.

  • NuMicro M251/M252 Series (3) Technical Features - Power Mode
    トレーニング  こうぐ  学ぶ  ビデオの長さ - 4:26
    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.

  • NuMicro M251/M252 Series (9) Quick Start a NuProject - Run Sample Code
    トレーニング  こうぐ  学ぶ  ビデオの長さ - 2:21
    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.
