[i=s]This post was last edited by sjtitr on 2014-2-15 01:47[/i] I am very happy today. I received the small board back and can start the actual practice. We started right away. For some reasons, we st...
The experiment is to control the on and off of an LED by pressing a button, but on the development board, the result is that the K1 button (GPIO12) controls LED5 and 6 (GPIO4 and GPIO5) to light up to...
[size=4]Many engineers who have never used switching power supply design will have a certain fear of it, such as worrying about the interference of switching power supply, PCB layout problems, paramet...
I learned about single-chip microcomputers while participating in an electronics competition. Now I want to make my own single-chip microcomputer development board. I don't know what the development b...
Today's portable medical devices allow patients to diagnose and treat themselves, move around freely, and even use the devices when they are out and about. To achieve the "easy to carry" feature, po...[Details]
