When the activity just started, I was doing an internship and was half a month late.I spent an entire night reading all the posts.However, I found that there was little mention of the specific perform...
I have a power bank with a single TP4201b main control unit and load detection. That is, it will only boost the voltage for charging when a load is connected. If there is no load, the boost will stop ...
I would like to ask the seniors to help look at my interrupt setting function. Why can't I enter the external interrupt? EXTI_SWINT_Enable (EXTI_LINE1) is set to generate a software interrupt and it c...
1) The size of the pads of the patch layer and the circuit layer is consistent with the size of the pads of the bare copper of the physical PCB. This is the basis for the size of the opening (a necess...
]The previous one is a RC attenuation circuit. When the attenuation is 100 times, the follower output is normal, but when the attenuation is 10 times, the follower output is amplified. 10M bandwidth i...

LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
We know that the inverter consists of two parts: the main circuit and the control circuit. Due to the nonlinearity of the main circuit (switching action), the inverter itself is a source of harmoni...[Details]
With concerns about the growing energy crisis, motor efficiency has become an important and timely topic. This is because motors use 63% to 70% of the electricity produced in the United States and ...[Details]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[Details]
Only a small number of LED manufacturers can produce high-quality LEDs. For applications that are only used for simple indication, low-quality LEDs are sufficient. However, high-quality LEDs must...[Details]
