0.56 two digital 5621BH Shu Shu Shu 5621AH large favorably 2.1 Introduction digital is actually made up of seven-eight light-emitting tubes constituted, plus a decimal point eight. These segments respectively, by the letters a, b, c, d, e, f, g, dp expressed. When a particular segment LED voltage is applied, these particular segments will light up to form two 8 digital words of our eyes to see the tube. Such as: display a "2", then it should be a bright light b e g bright bright bright f d c does not light does not shine bright dp. LED digital tube have generally bright and super bright different points, there are 0.5 inch, 1 inch different sizes. Strokes small size digital tube display common one light emitting diode, and large-size digital tube is made of two or more light emitting diodes, under normal circumstances, a single light emitting diode voltage drop is about 1.8V, current does not exceed 30mA. The anode is connected to the light-emitting diode is connected to the positive supply together is called a total of Yang digital tube, light emitting diode cathode connected to the negative power supply connected together referred to as common cathode LED. Numbers and characters commonly used in LED digital display is 0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F. 2 structural principle led digital tube (LED Segment Displays) by a plurality of light emitting diodes are packaged together to form the "8" shaped device, the lead is connected internally done, just lead their respective stroke, a common electrode. led digital tube used is generally the number of segments plus a decimal point and some 7-segment, there is a similar three "+1" type. Median half position, 1,2,3,4,5,6,8,10 bits, etc. ...., led digital tube connection according to the LED divided into a total of yin and yang categories, understand LED These characteristics of the program is very important because different types of digital control, in addition to their hardware circuits are different, the programming is different. Figure 2 is a common cathode and common anode LED internal circuit, and their light-emitting principle is the same, but their supply polarity is different. Colors are red, green, blue, yellow and so are several. led digital tube is widely used in instruments, clocks, station, home appliances and other occasions. Pay attention to the selection of product size color, each stroke power, brightness, wavelength etc. are the corresponding letter indicates DP decimal point A, the static display driver: static drive, also known as DC drive. Static drive means for each digital code for each segment by a microcontroller I / O port to drive, or use as BCD code two - Decimal * is * driving. Static drive advantage is simple programming, high brightness display, the disadvantage is occupied by I / O port and more, such as drive five digital static display requires 5 × 8 = 40 根 I / O port to drive, you know a 89S51 microcontroller available The I / O Eloquence 32 yet. We must increase the actual application * drive for drive, increasing the complexity of the hardware circuit. B, dynamic display driver: digital dynamic display interface is one of the most widely used microcontroller, a display mode, increase public very COM bit strobe control circuit for each digital control, bit strobe I by separate / O line control, microcontroller for bit strobe COM side of the circuit control, the digital control of strobe control we just need to show the open, the bit on the show shape, no strobe light digital tube will not . Through sharing in turn control the COM terminal of each LED digital tube, it makes each turn controlled digital display, which is a dynamic drive. Digital lighting time per bit is 1 ~ 2ms, because the human persistence of vision effect phenomenon and afterglow light-emitting diode, and despite the fact that you are not at the same time digital tube lights, but as long as the scan fast enough to people the impression that a stable set of display data, there will be no light flashes, dynamic and static display effect is the same, can save a lot of I / O ports, and lower power consumption. 3. [] 1 super energy-efficient LED advantages: saving 90% electricity, super energy-efficient, super-power! 2. Long life: ordinary incandescent, halogen 10 times 3 Super Green: no radiation, no flicker (low-voltage constant current power supply, light intensity remains unchanged, there will be no flashing, no ultraviolet light, no electromagnetic waves) 4. widely used digital control for me and static dynamic digital tube digital control, dynamic digital tube simply understood as a digital pin can simultaneously control one or more of the multiple strokes, just the opposite, static digital tube Strokes can control only one foot on the rice cooker / cooker / variety of instruments and control panels, and other products applied to the chip used in Taiwan-country imports, Opto, Wah Kwong, Lei Chau, wafer, Chau and other ultra bright chip technology, consistency, and high stability. Do plastic irrigation. It can also be customized according to customer requirements of any emission color. LED display can show changes in the numbers, text, graphics and video; not only the indoor environment can also be used for outdoor environment, with a projector, TV wall, LCD screen can not match advantage. LED by the wide attention and rapid development, it is that it itself has the advantage inseparable. They sum up these advantages are: high brightness, low voltage, low power consumption, small size, long life, impact resistance and stable performance. LED is extremely broad prospects for development, the current is moving higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability, full color direction. 5. LED digital control pin measuring find public common cathode and common anode common. First, we find a power supply (3-5 volts) and the resistance of different specifications, VCC and GND after series resistors connected in any two feet combinations are many, but there is always a LED will light to find a enough, then do not move GND, VCC (Series Resistance) one by one to touch the rest of the foot, if there are multiple LED (usually 8), that it is even a shade. In contrast with fixed VCC, GND individually touch the rest of the foot, if there are multiple LED (usually 8), and that it even Yang. Can also use the digital multimeter, the red pen is the positive power supply and the black one is negative power. 2.1 Introduction of digital tube is actually made up of seven-eight light-emitting tubes constituted, plus a decimal point eight.
