///*** *** *** * //一、程序说明： //1, 24LC02器件地址是1010000R/W. //2, 数组写入24LC02采取页写方式. //3, 数组code从24LC02读出时采取自由读方式. //4, 采用4.00M晶体。 //5，采用软件I2C。 //二、硬件连接： //1， SDA------->23 pin.(当然你可以任意选择脚位） //2, SCL------->18 Pin.(当然你可以任意选择脚位） //3， PORTB----->数码管的段输出 //4， RD4，RD5，RC6，RC7------->数码管的位输出(数码管为共阴极） -///*******************// A description of the procedures:// 1, 24LC02 device address is 1010000R/W.// 2, write an array to take 24LC02 page write mode.// 3, the array read out the code from the 24LC02 to take a free read.// 4, using 4.00M crystal.// 5, using software I2C.// Second, the hardware to connect:// 1, SDA-------> 23 pin. (Of course, you can choose to pin)// 2, SCL-------> 18 Pin. (Of course You can choose pin)// 3, PORTB-----> digital tube output segment// 4, RD4, RD5, RC6, RC7-------> digital pipe-bit output (digital tube for a total of cathode)
