FPGA/CPLD learning board based on EPM240

FPGA/CPLD learning board based on EPM240
     I wanted to learn verilog hdl, but the FPGA development boards on the market were too expensive! >w< So I drew one myself. The cost of the main control is only 10 yuan. If you have some components yourself, the cost will be very low. It is suitable for doing some small logic verification experiments when learning Verilog language. You can refer to it. Hope it helps!
Note:
     The main control is inter Altera's epm240t100c5n, which belongs to cpld and has a different name from fpga, but the development method is similar. However, compared with FPGA, it is more convenient without the need for program solidification operation.
 
Overall design block diagram:  
Software description
     The software uses quartus, and the recommended version is quartus13.1 because it is faster to synthesize.
Pin assignment: see attachment. Ways to collect dust



from physical display : 1. Find a mobile phone holder and put it on it. 2. Place it in a dusty place. 3. Blow it regularly. Notes 1. The pins of epm240 are grounded by default when not programmed, which will cause the LED light to light up inexplicably. The change method is:       Step 1: Open Assignment and select Device. 2. The LED light is lit with negative logic. The lighted light represents 0. When writing the logic, you can add an inverter to change it. The demo video has no other attachments to upload.
