In this lecture we created 4 digit seven segment display multiplexing code. We used xilinx nexys 3 fpga board. fpga seven segment decoder and multiplexer. This vhdl tutorial for beginner explains how to interface 4 digit multiplexed digit with spartan 6 FPGA in VHDL language.
To multiplexed we used time division multiplexing and provide 1 milisecond clock source to refresh every digit. To achieve this we used clock division from our previous tutorial of led blinking in VHDL where we explained how to make a clock divider in VHDL. We know that the Nexys 3 Board have 100MHz clock input so we need to wait for 10000 clocks. We did this by adding a signal of type natural range 0 to 10000 :=0;
In this clock division we changed the common anode terminals of the digits and rotate the digits.
