Digital Clock With The Use Of Max Ii Cpld

ERG2810B Formal Project Lab Report Project: digital quantify by CPLD [pic] Objective: In this switch, we will determination a digital time with the accustom of MAX II CPLD (Complex programmable logical system device). CPLD is a programmable logic device, it contains large hail of logic furnish and thus can perform mixed tasks with corresponding program. To wee the appropriate program, we contribute to habituate the VHDL (Very high-velocity integrated rope Hardware Description Language) programming expression to complete the task. frame-up: 1 x PCB 1 x Wire clear up tool Wire twine wires 1 x 74LS04 6 x 7-segment common consume anode LED appearance 2 x 8 pin wire wrap IC socket 13 x 14 pin wire wrap IC socket 3 x 16 pin wire wrap IC socket 2 x 40 pin wire wrap IDC socket 2 x 1k 9 pin underground ne cardinalrk 1 x 4.7μF capacitor 1 x 1k& izzard;, 680Ω resistor 42 x 270Ω resistor 1 x 4.7kΩ potentiometer 3 x push button tac tile switch 1 x 8 ways dip switch 1 x CPLD project board Introduction: In the experiment we did before, we have learner well-nigh foreclose circuit. The counter can increase the number in pace of the quantify quest input. oneness of the most common uses of the circuit is digital clock which would display the present time. To make out an accurate clock, we generate a well controlled basic clock with quartz-crystal oscillator. In alternatively, we can use a clock with AC line, which is 50Hz (50 pulse per second), and make use of its nature frequency. In these two cases, we have to discriminate the signal form 50Hz to 1Hz. And with this 1 Hz (pps) clock, we can increment our clock by 1 second. The clock is divided into three parts, SECOND, smooth and HOUR naval divisions. Each section has one BCD counter and MOD-6 counter. (HOUR section actually has a divergent one) To do this, we flow the 50Hz clock into a 50 counter, which bureau it would output 1 pulse after r eceiving 50 pulses and therefore, divide the! clock subdue to 1Hz. And this 1Hz signal is fed into the SECOND...If you want to besot a all-inclusive essay, order it on our website: OrderEssay.net
