SPI驱动屏幕,与HDMI驱动不同,它通过GPIO与Pi连接,Pi通过GPIO(SPI)输出画面数据。虽然它不能直接显示 OS 桌面,但它是对客户开放的,适合编程使屏幕可以显示您在代码上开发的任何内容。SPI驱动屏幕也有很多尺寸,有2.8寸、3.2寸、3.5寸等等,3.5寸或3.2寸的都足以显示画面,握持舒适。此外,该屏幕与 PI 配合使用具有更...
PI有SPI、TTL串口、I2C、USB。该协议需要快速和简单,因此选择 SPI 作为物理传输。下一个问题是如何向FPGA发送简单的读写命令并进行处理。此外,如果有一种方法可以添加功能/外设,那就太好了。 FPGA通信设计 为了简单起见,让我们使用硬件总线,它有一个定义的方式来访问不同的内存块,例如: 地址即32位:访问不同的...
