电子钟或万年历程序，很实用的，有闹钟，年、月、日等-Electronic clock or calendar program, it is useful, there is an alarm clock, year, month, date, etc.

应用背景 单片机通过CH375链接USB口的打印机 // 单片机通过CH375控制USB打印机  // 程序示例,C语言,CH375中断为查询方式,只负责数据传输,不涉及打印格式及打印描述语言  // 另可提供多台计算机共享一台USB打印机的方案  // 以下定义适用于AVR 单片机,其它单片机参照修改,为了提供C语言的速度需要对本程序进行优化  关键技术 /* PORTB |= 0x08;  // 输出A0=1  PORTA = mCmd;  // 向CH375的并口输出数据  DDRA = 0xFF;  // 并口D0-D7输出  PORTB &= 0xF9;  // 输出有效写控制信号, 写CH375芯片的命令端口, A0=1; CS=0; WR=0; RD=1; DDRA = 0xFF;  // 该操作无意义,仅作延时,CH375要求读写脉冲宽度大于100nS  PORTB |= 0x07;  // 输出无效的控制信号, 完成操作CH375芯片, A0=1; CS=1; WR=1; RD=1;  DDRA = 0x00;  // 禁止数据输出  PORTB &= 0xF7;  // 输出A0=0; 可选操作  */

CRC校验采用多项式编码方法。多项式乘除法运算过程与普通代数多项式的乘除法相同。多项式的加减法运算以2为模，加减时不进，错位，如同逻辑异或运算。-CRC polynomial used coding method. Polynomial multiply and divide computing process and the general polynomial algebra multiply and divide the same. Polynomial and subtract operations for the two to die, not into the Modified, dislocation, as logical XOR.

The program was written with some object-orientation in mind, which means that all functions that operate on a certain structure, has the structure s name as prefix in the function name, for example "Bitstream_get" which gets bits from a bitstream structure. -The program was written with some object-o rientation in mind, which means that all functions that operate on a certain structure, has the structure"s name as prefix in the functio n name, for example "Bitstream_get" which gets bits fr om a fade structure.
