Two LED digital tube pin number and name, use
Static display driver:Static drive is also called DC drive. Static drive refers to each digital tube of each segment by a microcontroller I/O port for driving, or use such as BCD code two - decimal injector drive. The advantages of static drive is simple programming, high brightness display, the disadvantage is occupied by I/O port, such as drive 5 digital tube static display is 5 x 8=40 I/O port to drive, you know a 89S51 microcontroller I/O ports available to 32. Therefore, the driver must be added to drive in practical application, which increases the complexity of the hardware circuit.
LED digital tube to display properly, will use the drive circuit to drive the digital tube of each segment, which shows the digital, so according to the driving methods of LED digital tube is different, can be divided into static and dynamic type two.
Dynamic display driver:Digital tube dynamic display interface is one of the most widely used display methods in SCM. Dynamic drive is the 8 display strokes of all digital tubes: A, B, C, D, e, F, G, DP
