I want to ask you how to use the io interrupt hardware of msp430f149. Use a non-self-locking switch, that is, a switch that is pressed and popped up. Connect the two ends of the switch to the P1 or P2...
I have a board in my hand. I use the program I wrote before (RTC as a perpetual calendar). On other boards (development boards, circuit boards designed by myself), the clock can be used normally. Howe...
International standards are generally formulated by Westerners. The original versions are in English, and the so-called Chinese versions are often direct translations of the original versions. In many...
I am a student majoring in computer network engineering. I have been working on a MCU project with a team for a year (mainly using Lingyang 61 to develop an item manager). After a year, I found that t...
I use CCS3.3 to debug the SD card project, but it works when I import the project into CCS5.4. When I click the run button, the program does not jump to the main program, but to other places, as shown...
This paper designs a dot matrix LED text display screen that is easy to update, expandable, and low-cost. The way to reduce costs is
① Use the Bluetooth data transmission function of mobile ph...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]

In today's body control module (BCM) designs, savvy engineers are moving away from electromechanical relays whenever possible. Their next step is to eliminate fuses. But is eliminating fuses a nece...[Details]
Spatial Division Multiplexing (SDM) MIMO processing can significantly improve spectrum efficiency and thus greatly increase the capacity of wireless communication systems. Spatial Division Multip...[Details]
LED light sources have many environmental advantages, but early products still have certain technical bottlenecks in heat dissipation and high brightness design that cannot be broken through....[Details]
Introduction
In industrial control, speed measurement is often required. Generally, a contact tachometer is used. This tachometer must be placed against the center of the shaft to measure. It...[Details]
