芯片本身就是一直在刷新显示，有一定的闪烁，但一般不仔细看，是看不得不明显！

TM系列的芯片 直接使用他们官方的参考源码即可。还有就是 它不需要CPU频繁发送信号，数据被修改一次 写入一次即可
我这里有个TM1629的贴子   希望能帮到你。http://www.51hei.com/bbs/dpj-200962-1.html

闪烁一般是由于延迟时间没有达到眼睛感官的要求，减少延迟时间，应该能够解决

数码管用手机拍都很容易捕捉到闪，只是调整到人眼看不出来就可以了。
写过1640的只要一行就算每个共阳数码管独立安装脚位不同也只要每管一行看你前面的u8 const code DM[69][14]等这些有点密集恐惧症的感觉 推测可能是每显一位都要全刷刷得过于频繁而这个芯片显然可以独立显示每一位精减一下程序单刷就好。

谢谢 但是规格书上共阳的显示确实要多行才能完成一个字符显示呀
图8给出共阳数码管的连接示意图，如果让该数码管显示“0”，那你需要在GRID1，GRID2，
GRID3，GRID4，GRID5，GRID6为低电平的时候让SEG1为高电平，在GRID7为低电平的时候让SEG1为
低电平。要向地址单元00H，02H，04H，06H，08H，0AH里面分别写数据01H，其余的地址单元全部
写数据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为P管开漏输出，GRID1-7为N管开漏输出，在使用时候，SEG1-11只能接LED的阳极，
GRID只能接LED的阴极，不可反接。

如果把显示函数改为每秒刷新一下 只能显示个位，十位闪一下 被覆盖了  因为地址都是相同的   

还是没有解决，没有思路
