其中后两种接口,3-wire 用到了 SCL / SDI / SDO / CSX 四根线,4-wire 用到了 SCL / SDI / SDO / CSX / DCX 五根线,所以所谓的 3-wire,4-wire 并不是指信号线的总数目,而是指有没有 DCX 线。LCD 用 DCX 来区分传输的数据是 Data 还是 Command。4-wire 模式下,用 DCX 信号线的电平高低来指...
1. “wire”-> <几线制>参数 用于声明SPI总线使用的是几线制,这里的线包括数据线SDI( 屏端SPI数据输入端),时钟线SCK(屏端SPI时钟输入口),片选线CS(屏端SPI片选信号输入口),数据命令选择线DCX(屏端SPI数据和命令选择输入口)四根信号线,SDO(屏端SPI数据输出口)不在这个计算范围;SPI接口通常 有两种:3线制...
