静态驱动也称直流驱动。静态驱动是指每个数码管的每一个段码都由一个单片机的I/O埠进行驱动，或者使用如BCD码二-十进位*器*进行驱动。静态驱动的优点是编程简单，显示亮度高，缺点是占用I/O埠多，如驱动5个数码管静态显示则需要5×8=40根I/O埠来驱动，要知道一个89S51单片机可用的I/O埠才32个呢。故实际应用时必须增加*驱动器进行驱动，增加了硬体电路的复杂性。

結果 (英文) 1:

Static drive also known as the DC drivers. Static drive refers to each digital control of each segment is driven by a microcontroller I/O ports, or b using a BCD-decimal * * drive. Static driver has the advantage of easy programming, display high brightness, disadvantage is that uses I/O ports much, driven 5 digital tube driven static display you need 5x8=40 I/O ports, you know a 89S51 microcontroller I/O ports that are available are only 32. Practical applications must be increased * drive for drive, increase the complexity of the hardware circuit.

結果 (英文) 2:

Static drive, also known as DC drive. Static drive means each digital code for each segment by a microcontroller I / O ports to drive, or use as BCD code two - Decimal * is * to drive. Static drive advantage is simple programming, display brightness, the disadvantage is occupied by I / O ports and more, such as driving five digital static display requires 5 × 8 = 40 根 I / O ports to drive, you know a 89S51 microcontroller available The I / O ports only 32 yet. Therefore, the practical application * must be increased to drive the drive, increasing the complexity of the hardware circuit.

Static drive, DC drive. Static drive refers to each digital tube of each segment by the I/O port of a microcontroller to drive, or use such as BCD code two - decimal * is * drive. The advantages of static driving is simple programming, high brightness display, disadvantage is the occupation of I/O port, such as drive 5 digital tube display static is 5 × 8=40 root I/O ports to drive, to know what a 89S51 single chip computer I/O ports available for only 32. The application must increase * drive drive, increases the complexity of the hardware circuit.
