Seven-segment usually contains the LEDs are arranged in a figure eight pattern.<\/span> 1:26 Picture shows the configuration of antarmnuka 7-segment common cathode (CC) with mikrokontroler.IC CD4511 is IC decoder BCD to 7-segment.<\/span> Microcontroller provide equivalent BCD code with the digit 7-segment will ditampikkan through to IC 4511. Seven-Segment Display can also be connected directly without using a decoder BCD to seven-segment.<\/span><\/p>\n In this case the code of the digit seven-segment program produced by the microcontroller itself.<\/span> Figure 2.21 shows the direct relationship to display common anode.<\/span> If you want to use more than one display, then the display on-multiplex-kan.<\/span> The human eye can not detect flicker display if the display flashes every 10 ms.<\/span> Time 10 ms divided by the number of displays used to obtain rectification time interval between each display.<\/span><\/p>\n Pictures 1:27 menunujukan multiplex circuit for two common cathode display.<\/span> IC 7438 is a line of 3 to 8 of the decoder is used to select the display.<\/span> 1:28 Picture shows the multiplex of display common anode for a direct connection without using a driver BCD to 7-segment.<\/span><\/p>\n Figure 28 display common cathode configuration interface with a microcontroller<\/span><\/p>\n Figure 29 circuit direct relationship to display common anode<\/span><\/p>\n
