PIC单片机SPI通讯的规划

PIC单片机SPI通信的设计-const uchar table[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,

0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71};

uchar data_temp;

void delay(uint x);

void init();

void didi(uchar num);

void disp(uchar num1,uchar num2,uchar num3,uchar num4,uchar num5,uchar num6);

void comm(uchar data);

uchar read(uchar add);

void write(uchar add,uchar wdata);

void write_enable();

void main()
