Oled implements animation display - basketball boy

Oled display module, using char definition to clear the interface will cause snowflakes on the screen; if char i, j; is signed, it means from -128 to 127, which will cause some numbers to be swallowed, use int or unsigned char (meaning none symbol)

Equipment: 51 development board and 0.96-inch 4-pin OLED display module.

To put it bluntly, the animation display is to separate the GIF image into a frame-by-frame picture, and displaying a picture is similar to displaying a picture.

Step 1: Extract and separate images. Gifsplitter is recommended.

Step 2: Reduce the image quality, change the picture to bmp format, and adjust the size to 128×64 (you can adjust it in the software or use the Windows drawing application). The details are as follows:

Step 3: Take the modulus of the picture (the most cumbersome step, where is the one-click modulo software, I am eager to tell you) I am using CopyLeft Bu Horse2000 here, and it is recommended to use PCtolCD

After taking the modulus, add the array to it. The specific code is as follows:

#include "reg52.h"
#include "intrins.h"

sbit scl = P0^1;
sbit sda = P0^3;


void IIC_Start()
{
    
    
    scl = 0;
    sda = 1;
    scl = 1;
    _nop_();
    sda = 0;
    _nop_();
}

void IIC_Stop()
{
    
    
    scl = 0;
    sda = 0;
    scl = 1;
    _nop_();
    sda = 1;
    _nop_();
}

char IIC_ACK()
{
    
    
    char flag;
    sda = 1;//就在时钟脉冲9期间释放数据线
    _nop_();
    scl = 1;
    _nop_();
    flag = sda;
    _nop_();
    scl = 0;
    _nop_();

    return flag;
}

    for(i = 0; i<8; i++) {
    
    
        scl = 0;//scl拉低，让sda做好数据准备
        sda = dataSend & 0x80;//1000 0000获得dataSend的最高位，给sda
        _nop_();//发送数据建立时间
        scl = 1;//scl拉高开始发送
        _nop_();//数据发送时间

This code will cause some problems with Oled’s display frame rate. It should be due to too many delay functions, code redundancy or other problems. Welcome to communicate and solve.
