Hello~ Everyone~ It’s time to review the highlights of the week again~ Come and see what wonderful posts, resources and activities there were in the past week~ Don’t miss any of the highlights! [size=...
I made a PID circuit for laser power. It will be affected when someone is walking around, but it will not change when no one is around. Because it is a fiber laser, there is no space part in the optic...
I want to use 51 single chip microcomputer to make a waveform recognition device. It can distinguish external sine wave, triangle wave and square wave signals. What algorithm should be used to impleme...
We have a device that uses a 08 card to control the movement, and the grating ruler is used as a displacement sensor. The signal output is connected to the 08 card, and the middle is connected as show...
As an RF engineer, your work will more or less involve power amplifiers. Power amplifiers can be said to be a hurdle that many RF engineers cannot avoid. Functions, classifications, performance indica...
Main programI am using STM32F103C8T6, driving SIM800C. The original program was good. Later, the hardware was changed, and DTR and STATUS were added as shown in the figure. I checked the manual and fe...
