第一种方法 - 无视注释,直接用2560的SPI引脚对SD卡进行读写操作,2560 对应SPI引脚如下 #define PIN_SPI_SS (53) #define PIN_SPI_MOSI (51) #define PIN_SPI_MISO (50) #define PIN_SPI_SCK (52) 1. 2. 3. 4. 程序运行得到的结果是Initializing SD card...initialization failed!!! 第二种方法 ...
(4)在Sd2Card.h中找到#define MEGA_SOFT_SPI 0这一行,将0改为1,启用mega软SPI,保存文件。 经过这样操作后,Arduino Mega 2560就可以使用TFT液晶屏中的SD卡模块了。使用IDE版本为1.8.6,例子文件Example08-ShowBMP,SD卡中的图片文件成功显示。 2.4''TFT液晶安装在Mega2560 ...
For SPI communication, use theSPI library. The USB host interface given by MAX3421E IC allows the ADK Arduino to connect and interact to any type of device that have a USB port. For example, allows you to interact with many types of phones, controlling Canon cameras, interfacing with ...

//End of example library #endif 现在,第一次包含库时,预处理器会检查是否存在用“_EXAMPLE_LIBRARY_H”定义的内容。由于没有类似的东西存在,预处理器继续下一行并定义一个名为“_EXAMPLE_LIBRARY_H”的常量。然后,库代码被复制到程序中。 当第二次包含库时,预处理器会再次检查是否存在名为“_EXAMPLE_LIBRARY...
找到显示屏spi的地址,修改成 0x3C(源库代码打开可能是0x3D) 源代码修改 开启128*64的注释(ESP8266-07使用的是这个正常工作) 关闭源代码 128*32的注释(arduino mega 2560使用的是这个正常工作) 直接烧录 有报错 参看1 mega 2560板子型号选择 ESP8266-07板子型号选择 ...
打开file-example-mpu6050-mpu6050_DMP6,有现成的实例代码。由于我的esp32的板载LED灯的pin number是2,修改#define LED_PIN 13为2。中断pin 2修改为#define INTERRUPT_PIN 13 //修改后 #define INTERRUPT_PIN 13 // use pin 2 on Arduino Uno & most boards #define LED_PIN 2 // (Arduino is 13, ...

I have a USB Host shield from Sparkfun (new version) and I have to make it work with an Arduino Mega 2560, but still not getting success. I’ve done some tests like: connect D7 to reset, making connections SPI pins according to the mega, I used an external power supply, but nothin...
Hate to say it but the xmega128a3u is about half the price at $4.75 (but no stock at the moment at digikey or mouser). Only half as much ram but more Usarts, more TWI and SPI I/O as well AND USB . Guess it’s time to port arduino Leonardo to xmega! Reply John-Mike ...
