arduino_ssd1306(128*64) _基于spi方式的oled显示logo位图(基于adafruit ssd 1.1.2版本的库+新版本)
关于接线
老版本库示例的运行
这是比较老的库在默认值上遇到的问题(建议使用新版本的ssd库)
首先将引脚的宏配置为和实际连线相对应的引脚数值
按情况进行调整,其中的D0,D1分别是sck和mosi
code
注意修改display.drawBitmap()的参数:
.ino文件
(我将库实例代码根据实际的引脚连线和自定义logo,绘图函数参数,以及只调用部分绘图函数几方面做了修改)
当然,你肯能还需要修改adafruit_ssd1306头文件.h中的屏幕分辨率定义
