这个是用于BPI-M1的
使用wiringPi库
要加载请用gpio load spi命令
效果如下，显示的是一个叫1024的图片
下边是程序52pi.c，附件中有程序和1024文件
- #include <wiringPi.h>
- #include <wiringPiSPI.h>
- #include <stdio.h>
- #include <stdlib.h>
- #include <stdint.h>
- #include <string.h>
- #include <time.h>
- unsigned char initcode[] = {
- 0xAE, 0xA8, 0x3F, 0xD3, 0x00, 0x40, 0xA1, 0xC8,
- 0xA6, 0xD5, 0x80, 0xDA, 0x12, 0x81, 0x00, 0xB0,
- 0xA4, 0xDB, 0x40, 0x20, 0x00, 0x00, 0x10, 0x8D,
- 0x14, 0x2E, 0xA6, 0xAF
- };
- unsigned char poscode[] = {
- 0x20, 0x00, 0xB0, 0x00, 0x10
- };
- #define BUFFER_SIZE 1024
- unsigned char buffer[BUFFER_SIZE];
- unsigned char buffer_temp[BUFFER_SIZE];
- void oled_begin();
- void oled_test();
- int main(void)
- {
- FILE *fphzk;
- time_t now;
- struct tm *timenow;
- wiringPiSetup();
- fphzk=fopen("1024","rb");
- fread(buffer,1,BUFFER_SIZE,fphzk);
- fclose(fphzk);
- oled_begin();
- time(&now);
- timenow = localtime(&now);
- printf("Start time is %s/n",asctime(timenow));
- oled_test();
- time(&now);
- timenow = localtime(&now);
- printf("End time is %s/n",asctime(timenow));
- return 0;
- }
- void oled_begin()
- {
- pinMode (5, OUTPUT) ;
- pinMode (6, OUTPUT) ;
- wiringPiSPISetup(0, 32*1000*1000);
- digitalWrite(6, LOW) ;
- delay(50);
- digitalWrite(6, HIGH) ;
- digitalWrite(5, LOW);
- wiringPiSPIDataRW(0, initcode, 28);
- }
- void oled_test()
- {
- int i,j,k;
- unsigned char temp;
- for(k=0;k<10000;k++)
- {
- digitalWrite(5, LOW);
- wiringPiSPIDataRW(0, poscode, 5);
- memcpy(buffer_temp, buffer, BUFFER_SIZE);
- digitalWrite(5, HIGH);
- wiringPiSPIDataRW(0, buffer_temp, 1024);
- for(i=0;i<BUFFER_SIZE;i+=128)
- {
- for(j=0;j<((i<256)?2:1);j++)
- {
- temp=buffer;
- memcpy(&buffer, &buffer[i+1], 127);
- buffer[i+127]=temp;
- }
- }
- delay(10);
- }
- }
编译请用命令gcc -Wall -o 52pi 52pi.c -lwiringPi
运行./52pi
相当富有动感，每秒能刷多少帧？自己测试吧
