芯片本身就是一直在刷新顯示，有一定的閃爍，但一般不仔細看，是看不得不明顯！

TM系列的芯片 直接使用他們官方的參考源碼即可。還有就是 它不需要CPU頻繁發送信號，數據被修改一次 寫入一次即可
我這里有個TM1629的貼子   希望能幫到你。http://m.raoushi.com/bbs/dpj-200962-1.html

閃爍一般是由于延遲時間沒有達到眼睛感官的要求，減少延遲時間，應該能夠解決

數碼管用手機拍都很容易捕捉到閃，只是調整到人眼看不出來就可以了。
寫過1640的只要一行就算每個共陽數碼管獨立安裝腳位不同也只要每管一行看你前面的u8 const code DM[69][14]等這些有點密集恐懼癥的感覺 推測可能是每顯一位都要全刷刷得過于頻繁而這個芯片顯然可以獨立顯示每一位精減一下程序單刷就好。

謝謝 但是規格書上共陽的顯示確實要多行才能完成一個字符顯示呀
圖8給出共陽數碼管的連接示意圖，如果讓該數碼管顯示“0”，那你需要在GRID1，GRID2，
GRID3，GRID4，GRID5，GRID6為低電平的時候讓SEG1為高電平，在GRID7為低電平的時候讓SEG1為
低電平。要向地址單元00H，02H，04H，06H，08H，0AH里面分別寫數據01H，其余的地址單元全部
寫數據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 06H
0 0 0 0 0 0 0 1 08H
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管開漏輸出，GRID1-7為N管開漏輸出，在使用時候，SEG1-11只能接LED的陽極，
GRID只能接LED的陰極，不可反接。

如果把顯示函數改為每秒刷新一下 只能顯示個位，十位閃一下 被覆蓋了  因為地址都是相同的

還是沒有解決，沒有思路
