CPLD development board has rich on-board resources.

The core device for including Altera EPM3128A and active crystals, active crystal frequency for 24 MHz. EPM3128A available I/O has drawn for external use, socket.

Display resources including 6 a total of seven period of digital tube, Yang eight LED (green), 1 slice 8 * 8 of LED dot matrix.

The keyboard resources including 4 * 4 buttons array, 4 independent key, and a reset button.

Interface resources including serial ports, IIC bus interface, PWM signal input and output port, USB Deivce interface (can be used as power supply power use), JTAG download interface, and EPM3128A available I/O interface. One JTAG download interface has two, one for 25 injection outlet, another way for 5 * 2 socket, the former can direct connection way PC, a parallel port after need to the ByteBlaster MV, ByteBlaster II or USB Blaster download line transfer to PC parallel port. Development board with a stick with the board 25 core cable to connect development board 25 injection interface to download, complete PC parallel programming download work.

Audio resources including a buzzer.

The power of one of LM1117-including 3.3 and USB interface, LM1117 3.3 provides 3.3 V dc power, the biggest can provide 800 mA output current. PC's USB interface can offer 5 V / 500 mA dc current, provide the CA329 as a power supply when using can meet the requirements CA329 power consumption.
Development board including very rich development examples, including not only EDA, including developing instance VS the.net 2005 development examples. EDA developing instance, Verilog all provide VHDL two versions, VS the.net 2005 development programming language, for example C# VS the.net 2005 and C# WINCE.net platform support is also the development tools and programming language.

Developing instance is as follows: EDA

Water light

Timing take turns the light development board eight LED display, produce flow, timing signal by the development board active crystals output frequency division to get.
Six decimal counter

For 0.1 s, low levels and adjacent between decimal carry high, with development board of six seven period of digital tube display the current count value.

Digital clock

With the development of the board six seven period of digital pipe display hours, minutes, and seconds. Hours, minutes, and seconds each takes up two digital tube.

Of LED dot matrix display dynamic scanning

Development board includes a 8 * 8 dot matrix, the timing of the LED display 0 ~ 9 examples in above of LED dot matrix, digital timer intervals by dial the code switch set to 0.1 s or 1 s.

The keyboard array-digital pipe display

Timing scanning the keyboard array, delay jitter read key state to after current buttons are displayed in six of the seven segment digital tube position, when a new keys pressed key value into the position of new digital tube, original moves left a become a significant time low. Can identify key value including 0 ~ 9.

The keyboard array-LED dot matrix display

Timing scanning the keyboard array, delay jitter read key state to after current buttons are displayed in the of LED dot matrix. Can identify key value including 0 ~ 9.

Serial send

Timing to send characters' 0 '~' 9 ", and "A '~' F 'to the receiving party, the serial port baud rate, data digits, parity bits, and stop bits, etc can all through the external set parameters, the instance of the parameters are part of dial the code switch to set by. The serial port for work on the clock development board 24 MHz active crystals, may realize the common output serial port baud rate.

Serial ports receive

Can receive characters' 0 '~' 9 "and displayed on the screen of LED dot matrix, the serial port baud rate, data digits, parity bits, and stop bits, etc can all through the external set parameters, the instance of the parameters are part of dial the code switch to set by. The serial port for work on the clock development board 24 MHz active crystals, may realize the common output serial port baud rate.

buzzer

Dial the code switch set by the frequency of the signal input buzzer, make a different tone buzzer.

Reset button and independent

Will a reset button and 4 independent button two levels of the connecting through reverse to five LED with keys pressed corresponding LED will be when a light.

Dial the code switch

Dial the code switch eight switch through the two levels of reverse device connected to the eight LED with a dial switch to "ON" when a corresponding will be lit LED.

Crystals test

Development board including a 24 MHz active crystals, in this instance by 24000000 points, produce a cycle frequency for 1 s clock, connected to a LED to test the 24 MHz active crystals work is normal or not.

PWM signal

Produce designated cycle and occupies emptiescompared PWM signal, and the cycle of empty by principle diagram than in these Settings, and at the same time PWM signal parameters through a serial port sent to a PC display.

PWM signal measurement

Measuring development board PWM socket on the frequency of the signal input PWM and occupies emptiescompared to, and the measured results showed that in the development of the eight LED on board.
