宅在家里仿個VFD數字時鐘，程序運行后，秒滿六十進位到時位，中間間隔分為始終為零。源程序就是這個論壇里的，修改步驟詳見注釋。請走過路過的幫忙看看，是哪不對？（原程序vfd_wrtime ()里就是秒位進時位）
/***************
20200209 修改來自51hei http://www.zg4o1577.cn/bbs/dpj-43390-1.html "基于89S52的16312VFD顯示程序"
本人硬件：MCU：STC12C5616AD、
修改：1.STB、CLK、DIN；
2.按VFD重新編碼0~9；
3.按PT6312這是顯示模式、數據模式設置；
4.按VFD實際屏蔽G6（是VFD屏下部分漢字，如：多謝惠顧等）；
5.10_8_VFD的G1在右側端頭，G5是左側端頭，在void vfd_wrtime ()里調過來
6.去掉秒、分個位、十位之間的空格，在分秒之間加一橫0x08
7.屏蔽vfd_wrdata ( g11[ i] );vfd_wrdata ( g12[ ] );
增加vfd_wrdata ( vfdbuf[2] ); vfd_wrdata ( vfdbuf[3] );
