GD32F310-硬件SPI驱动0.96LCD

SPI 简介及特点

具有全双工、半双工和单工模式的主从操作。
16位宽度，独立的发送和接收缓冲区。
8位或16位数据帧格式。
低位在前或高位在前的数据位顺序。
软件和硬件NSS管理。
硬件CRC计算、发送和校验。
发送和接收支持DMA模式。
支持SPI TI模式。
支持SPI NSS脉冲模式。
支持SPI四线功能的主机模式（只有SPI1）。

SPI模块可以通过SPI协议与外部设备进行通信。
串行外设接口（Serial Peripheral Interface，缩写为SPI）提供了基于SPI协议的数据发送和接
收功能，可以工作于主机或从机模式。 SPI接口支持具有硬件CRC计算和校验的全双工和单工
模式。 SPI1还支持SPI四线主机模式。
