I want to learn about Samsung's 2440 recently, and want to start from the bare metal with MDK. I don't know where to start. Is there any expert who has done it before and can give me some guidance? Th...
The single-chip computer model Atmega128 AD measures 0~5V and displays it on the computer through the serial port. I hope someone can write a program to help me. I am in a hurry. I have written a lot ...
If you know the pulse frequency and count value in the microcontroller, you can get the time, and then multiply it by the ultrasonic transmission speed to get the distance. How can I display the dista...
