I am now making a temperature measurement device based on Atmel sam d21. I have an Atmel sam d21 board and an extended version oled1xplained. I plan to use the DS18B20 temperature sensor to collect te...
This is a section of assembly code in STM8 motor, but after reading it, I just can't understand what it means. The low-level code is as follows:;********************* PHASE U duty cycle processing ***...
How can I write a program in Matlab to display the data file in a graphic? I know that I can use the fopen, fread, and fseek functions, but how can I draw the data in the binary file into a graphic? T...
Electronic systems are increasingly using RF sources in radio frequency (RF) applications such as automotive radar, 5G cellular, and the Internet of Things. All of these RF sources require ways to mon...
I recently used ulink2 to download programs, but an error dialog box always popped up: "cannot enter debug mode". I don't know what went wrong. I have been troubled by this for half a month. Now I can...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]

Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
