SPI stands for Serial Peripheral Interface used for the transmission of data between the controller and other peripherals components. Four pins i.e. 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS) are used for SPI communication. 尺寸图
TheArduino Mega 2560is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and ...
PWM:Pins 2 to 13 and 44 to 46 provide 8-bit PWM output with the analogWrite() function. SPI:Pins 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS) support SPI communication using the SPI library. They are also broken out on the ICSP header, which is compatib...
(serial port) is located on the same pins (0 and 1), as are external interrupts 0 and 1 (pins 2 and 3 respectively). SPI is available through the ICSP header on both the ADK and Duemilanove / Diecimila.Please note that I2C is not located on the same pins on the ADK (20 and 21...

pins. The ATmega2560 also supports I2C (TWI) and SPI communication. The Arduino software includes a Wire library to simplify use of the I2C bus; see the documentation on the Wiring website for details. For SPI communication, use the SPI library. Programming The Arduino Mega can be program...
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 ...
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...
