Singlechip beginners, please give some programming examples (in C language) to the master, and it is best to take notes. Thank you very much

# Define uint unsigned integer

# Define uchar unsigned characters

Uchar number;

Uchar code table [] = {

0x28，0x7e，0xa2，0x62，0x74，

0x6 1，0x2 1，0x7a，0x20，0x60，

0x30，0x25，0xA9，0x26，0xa 1，0xb 1 }；

Invalid delay (unsigned integer z);

TT uint k；

void main()

{

TMOD = 0x 0 1； //Timer0 setting mode 1

TH0 =(65536-50000)/256；

TL0 =(65535-50000)% 256；

EA = 1； //Open host interrupt

ET0 = 1； //Open Timer 0 interrupt

TR0 = 1； //Timer 0 starts to work.

k = 0；

TT = 0；

P2 = 0x 00；

while( 1)

{

If (tt==20)

{

TT = 0；

P0 = table [k];

k++；

If (k== 16)

k = 0；

p 1 _ 1 = 1；

}

}

}

Void exter0 () interrupt 1

{

p 1 _ 1 = 0；

TH0 =(65536-50000)/256；

TL0 =(65535-50000)% 256；

TT ++；

}

I wrote the timer basic program myself.

And interrupt the basic program.

# include & ltAT89X5 1。 H & gt

# Define uint unsigned integer

# Define uchar unsigned characters

Uchar number;

Uchar code table [] = {

0x28，0x7e，0xa2，0x62，0x74，

0x6 1，0x2 1，0x7a，0x20，0x60，

0x30，0x25，0xA9，0x26，0xa 1，0xb 1 }；

Invalid delay (unsigned integer z);

uint k；

void main()

{

P2 = 0x 00；

while( 1)

{

for(k = 0； k & lt 16; k++)

{

P0 = table [k];

Delay (200);

}

}

}

Void delay(unsigned int z) // delay function, where the value of z is the delay number of this function, such as delay (200); The delay is about 200 milliseconds.

{//delay (500); The delay is about 500 milliseconds.

Unsigned integers x, y;

for(x = z； x & gt0; x -)

for(y = 1 10； y & gt0; y-)；

}

Is it okay?
