i2c 是连接到LCD的I2C接口的I2C对象。 spi 是连接到LCD的SPI接口的SPI对象。 i2c_addr 是显示屏的I2C地址。 必须指定一个有效连接或所有PWR、I2C和SPI。若给定有效连接,则所有未作为参数传输的PWR、I2C和SPI(也就是说,其为 None )将根据连接值创建。若需要,这会允许覆盖显示屏的默认接口。 默认值为: “X”...

Hi there, recently I bought an Orange Pi Zero3 with 1GB RAM. I want to connect a 20*4 character LCD display(https://www.tinytronics.nl/en/displays/lcd/lcd-display-20*4-characters-with-white-text-and-blue-backlight-with-i2c-backpack) to it. I have previou
这几乎是没法用的,尤其是用GPIO来模拟协议(SPI,I2C,UART等),严格依赖于delayMicroseconds()函数的延时精准度。另外,树莓派的串口通信的波特率,也是严格依赖于cpu时钟频率。这2个需求,使得当我们使用树莓派的GPIO功能时,最好固定cpu的频率。 固定cpu频率有2个方法,任意选一种:...
