SPI是一种同步、高速、全双工的通信总线,全称为Serial Peripheral Interface(串行外设接口),由Motorola公司提出。在嵌入式系统设计时,常使用SPI接口连接一些传感器、外接存储器或通信模组,本期内容将通过RV-STAR和Arduino UNO间的SPI通信例程,带领大家了解SPI的应用方法。

(1) SPI_Direction 本成员设置SPI的通讯方向,可设置为双线全双工(SPI_Direction_2Lines_FullDuplex),双线只接收(SPI_Direction_2Lines_RxOnly),单线只接收(SPI_Direction_1Line_Rx)、单线只发送模式(SPI_Direction_1Line_Tx)。 (2) SPI_Mode 本成员设置SPI工作在主机模式(SPI_Mode_Master)或从机模式(SPI_Mod...

新建工程 平台选 esp32 开发板选 esp32dev 架构选arduino 然后搜 tft-espi 添加到这个工程里 把tft espi的例子文件夹里的内容拷贝到src文件夹里的cpp文本里 下来是按注释来修改User_Setup.h,位置在.pio\libdeps\esp32dev\TFT_eSPI\User_Setup.h

I have a mod for the Arduino SAMD21 core that gets close to full speed at 12 MHz using 8-bit SPI I/O. It is about three times faster than the Arduino core functions with SdFat. Here is the small but tricky implementation that takes advantage of buffer registers in the SAMD21/SAMD...
