ATmega 328驱动SPI模式的OLED屏代码
本帖最后由 希岩 于 2020-5-28 13:10 编辑在淘宝上淘了个OLED屏，花了不少钱*_*。1.3寸带中文字库的OLED屏，单色白。驱动为SSH1106，卖家给的例程是51和stm的。想来手头只有AVR的，就改写原来的程序了。花了不少时间终于完成了。不多说，上代码。适用于3.3V-5V供电，适用于ATmega48 ATmega48（去掉图片数组） ATmega88 ATmega168 ATmega328芯片。编译环境为ICCAVR7 ,适用于Arduino IDE（没亲自尝试，自己试吧）

谢谢啦！这个是用C语言写的，采用了AVRDEF 的头文件，而这个在Aduino IDE下都有，Arduino采用的是C++语言，兼容C语言的，你可以将这个拷过去做一些修改 希岩 发表于 2016-6-30 19:36

给你一个简化版的读字库的程序，原本在ICCAVR编译的，你可以转成Arduino的

{ //SPI模式3
DDRB|= (1<<DDB3)|(1<<DDB5); //设置MOSI 和SCK 为输出，其他为输入
SPCR = 0b01011001; //使能SPI 主机模式,时钟模式为下降沿，结束沿采样，设置时钟速率为fck/16
}
你好 我有一个问题 就是看了你的操作带字库的oled帖子时，51例程里面是这样的if( Rom_OUT )
ret_data=ret_data+1;
但是在arduino里面，把rom_out设置为输出模式后不是不能读取引脚的高低电平吗，如果把rom_out在设置为输入模式的话会不会影响他的输出高低电平状态？ 请问你是怎么解决的呢
