Recently, I wrote an electronic clock based on AT89C51 microcontroller. It uses 6-digit 12-hour display and 6 common anode digital tubes. The specific functions are as follows: the first digital tube ...[Details]

Delay is a function that is often used in assembly. That is, the MCU does nothing but delays for a period of time. The MCU itself has timers and counters, which can be used to realize delay. However,...[Details]

When ARM introduced 64-bit support for its architecture, it was designed to be compatible with previous 32-bit software. But for Linux programmers, there are still some significant differences that c...[Details]

Audio preference has always been considered a personal experience. What one person considers good may not be so for another. However, with the support of Personalized Spatial Audio in Apple iOS 16,...[Details]

　　Timing is described by timing units. MCS-51 has four timing units, which are beat, status, machine cycle and instruction cycle. Next, we will explain them respectively. 　　·Rhythm and status: 　　We d...[Details]

In order to save space in the data memory in Keil , an array or string is defined by the "code" keyword to be stored in the program memory:             uchar code buffer ={0,1,2,3,4,5};      uchar c...[Details]

　　Wireless power supply is a convenient and safe new technology. It does not require any physical connection, and the electric energy can be transmitted to the load without contact at a close distanc...[Details]

There are five 16-bit timers in S3C2440, timer0, timer1, timer2, timer3 and timer4. Among them, only timer4 is an internal timer without output pins. Therefore, only timers 0, 1, 2, and 3 have pulse ...[Details]
