The NuMicrofamily is Nuvoton 's latest 32- bit microcontroller product line based on the ARM Cortex-M0 with excellent on-chip peripheral features and connectivity .
NuMicrofamily is a low-power, high-...
I have a device. When I connect it for the first time, the system enumerates one interface, which is a SCSI class. When I remove it and re-enumerate it, it will enumerate another different interface. ...
1. Equivalent Splitting and Merging of Ideal Voltage Sources There is an ideal voltage source us between nodes N and q in the circuit shown in Figure 2-2-1(a). Now split the ideal voltage source into ...
Photovoltaic inverters are the core equipment of photovoltaic systems. Their main function is to convert the direct current generated by photovoltaic modules into alternating current that meets the...[Details]
International Solar Photovoltaic Network News: Chinese inverter company Sungrow announced that it will build a 3GW photovoltaic inverter manufacturing plant in Bangalore, the capital of Karnataka, ...[Details]
The status of interrupts in developing embedded systems is absolutely unquestionable. In the era of C51 microcontrollers, there were only 5 interrupts, including 2 external interrupts, 2 timer/counte...[Details]
After searching a lot of information, I finally understood the time base timer. I did not use any library functions but operated the registers directly. The following introduces the systick in STM32...[Details]

The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]
I have encountered many problems when tinkering with LD driver recently. I will record them one by one below. Otherwise, who will remember who in five hundred years? 1. Configuration issues of multi-...[Details]
Summary of STM32 peripheral DMA usage: 1. Select DAM mode according to your needs: (1) Circular mode—DMA_Mode = DMA_Mode_Circular (2) Normal mode—DMA_Mode = DMA_Mode_Normal 2. For Chanel3 of DMA1, t...[Details]
ADC: 1. The ADC module inside STM32 has three ADC1, ADC2, and ADC3, which are independent of each other, so synchronous sampling can be performed. 2ADC input clock must not exceed 14MHz, it is genera...[Details]
1. What is PWM What is PWM? Professionally speaking, it is pulse width modulation. In layman's terms, it is the continuous output of high and low levels. For example, the microcontroller outputs...[Details]
Assume that the crystal frequency of the microcontroller is 6MHz. It is required to use timer 1 in mode 0 to generate a continuous square wave pulse with a period of 500us, and output it from P1.0. T...[Details]
