Arduino驱动OLED显示屏试验

要是有I2C的库就好了。

请教一下，我用4线SPI连接到MEGA，你的库文件，发现刷新一次数据要220ms左右，怎么都觉得不应该这么慢啊…… ...

没道理啊，我没用过MEGA那么高档的东西

SS1306的驱动，特别流畅，超过了很多LED屏的显示速度

实在抱歉，我还不会自己写裤，只能改改。
这个裤驱动spi响应速度很快，做图形不错

哪位大师会用指令调节这个视频?

ssd1306说明书上查的指令，这个库里好像不带，396行写了功能，但空着。需要高人加入
//Set Fade Out and Blinking
//OLED_Send_Comm(0x23);
//OLED_Send_Comm(0x30);

我ssd1306.CCP里看到的是这行,可也是空的,郁闷
void SSD1306::ssd1306_set_brightness(uint8_t val) {

}

我实验的结果也是刷新一次耗时约200多ms.
Oled.display() 这函数,就占了200ms了.
乞求善心人士能提供8080的驱动...

我有8080的例子，谁会改

编辑帖子老出错。先说接线图。
由于OLED多工作于3.3v，因此为了匹配输入端电压，用了一块缓冲器CD4050.
介 ...

4050的1脚接5V？感觉不太对呢？

应该对吧。我最近尝试在数据线串了100r电阻，工作正常

什么时候教教我烧mega8吧，调到天亮都没弄出来

哈哈我的最小系统还在理论阶段呢，准备在成品板上调试好了再研究

128064也是接1脚，那岂不是5V给oled供电?

mega8 的bootloader吗？这个弘毅不是写出来怎么烧了吗？还是什么问题！

8L也木问题。。。我改造了一个8L的。。。今天做完事情，明天补充个帖子。
