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。

BOOT模式用于运行ESP32上的程序,而FLASH模式用于上传程序到ESP32。Strapping pins(引脚配置开关)用于配置ESP32的工作模式。通常情况下,带有内置USB/Serial的开发板会自动将这些引脚配置到正确的状态,以支持烧录或启动。然而,如果其他设备使用这些引脚,可能会导致ESP32进入错误的模式。
SPI To set SPI parameters, use the SPI options. The pins in theSPI0(default)option are the Arduino®header pins mentioned inhttps://developer.mbed.org/platformsfor the selected Nucleo board. Note For Arduino Uno R3 compatible boards, the pins D0-D15 can be accessed with 0-15 and pins...
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...
下面定义在我们的 SPI 通讯中要用到的 pins 引脚,DATAOUT, DATAIN, SPICLOCK 和 SLAVESELECT。然后定义 EEPROM 的控制指令(opcodes):接下来分配程序会用到的全局变量。我们将用 char buffer[128]来保存要传输到 EEPROM 的数据: 首先我们初始化我们的串口连接,设置我们的 input 和 output 模式并设置 SLAVESELECT...
