5、E2PROM 2864。4 1616掃描LED點(diǎn)陣。四、實(shí)驗(yàn)原理 1616掃描LED點(diǎn)陣的工作原理同8位掃描數(shù)碼管類(lèi)似。它有16個(gè)共陰極輸出端口，每個(gè)共陰極對(duì)應(yīng)有16個(gè)LED顯示燈。所以其掃描譯碼地址需4位信號(hào)線(xiàn)。要使16點(diǎn)陣上某個(gè)點(diǎn)亮，如第10行第4列的LED點(diǎn)亮，只要讓列選信號(hào)為“0100”，從而選中第4列，再給第10行一個(gè)高電平，即可點(diǎn)亮該LED。本實(shí)驗(yàn)通過(guò)FPGA芯片寫(xiě)入字形，產(chǎn)生掃描信號(hào)。為了顯示整個(gè)漢字，首先分布好漢字的排列，以行給漢字信息；然后以大于24HZ的頻率掃描列，即每行逐一加高電平，根據(jù)人眼的視覺(jué)殘留特性，使之形成整個(gè)漢字的顯示由于要顯示不同的字，需要給一個(gè)信DIN，對(duì)不

6、同字不同花樣進(jìn)行選擇。而該信號(hào)的產(chǎn)生可以通過(guò)一個(gè)16進(jìn)制計(jì)數(shù)器完成。本設(shè)計(jì)由16進(jìn)制計(jì)數(shù)器，行驅(qū)動(dòng)和列驅(qū)動(dòng)組成。輸出包括了如下圖所示的列選信號(hào)SEL0SEL3。五、程序設(shè)計(jì) 116進(jìn)制計(jì)數(shù)器：LIBRARY ieee;USE ieee.std_logic_1164.all;USE ieee.std_logic_unsigned.all;ENTITY JISHU ISPORT(CLK,RST,LOAD:IN STD_LOGIC; DIN:IN STD_LOGIC_VECTOR(3 DOWNTO 0); DOUT:BUFFER STD_LOGIC_VECTOR(3 DOWNTO 0);END JI
