標(biāo)準(zhǔn)數(shù)碼管筆段命名沒(méi)有強(qiáng)制規(guī)定，是行業(yè)慣例。數(shù)碼管分共陰或共陽(yáng)。特種數(shù)碼管都是定制。點(diǎn)亮數(shù)碼管的段碼也是按慣例接法編寫(xiě)，也可以自主改變接法并另行編碼。
常用的數(shù)碼管段碼數(shù)組：
//順序共陰極數(shù)碼管段碼表，段碼a-h順序接PX0-PX7
unsigned char code table[]={//共陰數(shù)碼管段碼"0~f-."
0x3f,0x06,0x5b,0x4f,
0x66,0x6d,0x7d,0x07,
0x7f,0x6f,0x77,0x7c,
0x39,0x5e,0x79,0x71,0x40,0x80};
//反序共陰極數(shù)碼管段碼表，段碼a-h順序接PX7-PX0
unsigned char code Table[]={//共陰數(shù)碼管段碼"0~f-."
0xFC,0x60,0xDA,0xF2,
0x66,0xB6,0xBE,0xE0,
0xFE,0xF6,0xEE,0x3E,
0x9C,0x7A,0x9E,0x8E,0x02,0x01};
//順序共陽(yáng)極數(shù)碼管段碼表，段碼a-h順序接PX0-PX7
unsigned char code table[]={//共陽(yáng)數(shù)碼管段碼"0~f-."
0xc0,0xf9,0xa4,0xb0,
0x99,0x92,0x82,0xf8,
0x80,0x90,0x88,0x83,
0xc6,0xa1,0x86,0x8e,0xbf,0x7f};
//反序共陽(yáng)極數(shù)碼管段碼表，段碼a-h順序接PX7-PX0
unsigned char code Table[]={//共陰數(shù)碼管段碼"0~f-."
0x03,0x9f,0x25,0x0d,
0x99,0x49,0x41,0x1f,
0x01,0x09,0x11,0xc1,
0x63,0x85,0x61,0x71,0xfd,0xfe};
