謝謝 但是規(guī)格書(shū)上共陽(yáng)的顯示確實(shí)要多行才能完成一個(gè)字符顯示呀
圖8給出共陽(yáng)數(shù)碼管的連接示意圖，如果讓該數(shù)碼管顯示“0”，那你需要在GRID1，GRID2，
GRID3，GRID4，GRID5，GRID6為低電平的時(shí)候讓SEG1為高電平，在GRID7為低電平的時(shí)候讓SEG1為
低電平。要向地址單元00H，02H，04H，06H，08H，0AH里面分別寫(xiě)數(shù)據(jù)01H，其余的地址單元全部
寫(xiě)數(shù)據(jù)00H。
SEG8 SEG7 SEG6 SEG5 SEG4 SEG3 SEG2 SEG1
0 0 0 0 0 0 0 1 00H
0 0 0 0 0 0 0 1 02H
0 0 0 0 0 0 0 1 04H

0 0 0 0 0 0 0 1 0AH
0 0 0 0 0 0 0 0 0CH
B7 B6 B5 B4 B3 B2 B1 B0
▲注意：SEG1-11為P管開(kāi)漏輸出，GRID1-7為N管開(kāi)漏輸出，在使用時(shí)候，SEG1-11只能接LED的陽(yáng)極，
GRID只能接LED的陰極，不可反接。
