[Zhejiang Sci-Tech University] A simple CNC DC regulated power supply design

Overview

1. Basic requirements (1) Output voltage: range 0~+9.9V, step 0.1V, ripple no more than 10mV; (2) Output current: 500mA; (3) Output voltage and current values can use OLED, LCD liquid crystal or LED Digital tube and other displays; (4) The two keys "+" and "-" control the step increase or decrease of the output voltage respectively.

Functional part (1) The output voltage can be preset at any value between 0~9.9V; (2) The output current can be set at any value between 0~500mA, with over-current constant current and short-circuit protection functions; (3) Use automatic scanning instead of manual button presses to achieve changes in output voltage (unchanged in steps of 0.1V); (4) Expand the types of output voltages (such as sine waves, triangle waves, etc.).

Help
Does anyone know how to sense a circuit 10 meters or more away? (That is, how to sense the voltage returned by the object or person in front of it) Can anyone tell me? I hope we can communicate with e
Data collision processing of RF multi-point communication of cc2530
I'm learning CC2530F256 recently. Now I'm debugging RF communication (simple RF communication, no protocol stack). Considering that there will be data collision during multi-point communication, how t
Please advise!!! About the peak detection circuit!!!
Now there is a sinusoidal voltage with a peak-to-peak value of 1 to 1.5V. Can the peak value be detected using the following diagram? If not, is there any better method? Thank you very much! ! ! In ad
A relatively novel approach to achieve
I recently found a clever part when I was looking at the code. When you usually use 12864 or 1602 to display numbers, I believe everyone will first split it up, convert it into the corresponding ASCII
