Q: 在Pi A, B上使用 A: 首先需要将树莓派的IIC线与LCD控制板的IIC总线手动连线在一起,包括SDA ( http://pinout.xyz/pinout/pin3_gpio2) 和 SCL (http://pinout.xyz/pinout/pin5_gpio3)。之后修改配置,在IIC总线上识别LCD: 注意: 其他IIC设备将无法使用。 Q: 屏幕左上角出现方形彩虹图标 A: 电源供...
So they forked this library and modified the pinout there. However, that fork is ancient, so I strongly suggest to use this original library instead. You can choose the Adafruit pinout with a command line flag. Just pass the option --led-gpio-mapping=adafruit-hat. This works on the C++ ...

That is easy enough to fix, the script sets this explicitly. Change: Those 'b' bits are brightness (see description above). Video of it working:https://filebin.pw/sJD/ Thanks to this thread, after hours trying to figure out what I had done wrong, I FINALLY realized that I too had ...
如果是用来接线的话,看 Board 序号可能更好找一点。如果不知道 BCM 和 Board 之间的对应关系时,也可以直接在树莓派中输入如下命令来查看: pinout 知道如何分辨树莓派上的接口后,我们再来看看墨水屏上的接口。这种墨水屏一般都会随屏幕附赠一条 8PIN 的连接线,调试的时候相当方便。
