EERPOM的引脚1连接Arduino的引脚10(Slave 片选),EEPROM的引脚2连接Arduino的引脚12(Master In Slave Out - MISO),EEPROM的引脚5连接Arduino的引脚11(Master Out Slave In - MOSI),同时EEPROM的引脚6连接Arduino的引脚13(串口时钟 SCK)。 4.Arduino SPI 编程 现在我们要编写能让Arduino和EEPROM进行SPI通信的代码了。

I have a small project using ePaper with LOLIN(Wemos) S2 mini. Initially, GPIO36 & 35 connected to SCK and MOSI using attached pinout diagram but it won't work. Then, I found that default SPI pins in arduino IDE are not correct. So, I have modified the pin number of RXTX, SPI an...

在Arduino中使用SPI 在Arduino中,可以使用SPI.h库来使用SPI外设。 在SPI.cpp源文件的最后面定义了SPIClass对象SPI: #if CONFIG_IDF_TARGET_ESP32 SPIClass SPI(VSPI); #else SPIClass SPI(FSPI); #endif 1. 2. 3. 4. 5. 在sdkconfig.h头文件中可以查看到已经定义了#define CONFIG_IDF_TARGET_ESP32 ...
