Those who are engaged in embedded development may have thought about this question: we usually use the driver library and initialization files provided by chip manufacturers, and write programs direct...
1. There are two reset signals for MSP430: power-on reset signal (POR) and power-on clear signal (PUC). a power-on reset (POR) and a power-up clear (PUC) signal.From the figure we can see:Powering up ...
Motor drive - BLDC sensorless methodThe system provides BLDC sensed, BLDC non-sense, PMSM and other driving modes. This test uses a 12V small motor with a BLDC non-sense driving mode.6-step BLDC drive...
In order to prevent traffic accidents, when the intelligent detection device of the car detects danger ahead, it must send a warning message to the driver. The voice alarm clearly reminds the drive...[Details]
Calibrators are widely used in university experiments. Among them, there are two experiments in nuclear physics experiments in modern physics experiments (GM counter and β absorption) that require ...[Details]

Cars are becoming an indispensable part of people's lives. However, what worries car users is that the theft of cars is increasing year by year. This paper aims to design a conven...[Details]
introduction
The most common flight state of a fixed-wing aircraft is horizontal flight. If it is allowed to fly at a large angle, the action cannot be maintained all the time. If it is al...[Details]
There are many ways to attenuate signals. The most commonly used method is to divide the voltage using resistors. The common circuits are as follows:
Oscilloscope pre-stage attenuation c...[Details]
