The Arduino Mega 2560 is 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, ...
TWI:Pin 20 (SDA) and 21 (SCL) support TWI communication using the WIRE library. AREF:The reference voltage for analog inputs is used with analogReference(). Reset:for this pin bring the reset line LOW to reset the microcontroller. This pin is typically used wh...
2. 外部接口在2011版本基础上增加了sda、scl(位置在aref的左侧)。ioref接口可以提供给shield一个电压参考。并且为了将来的系列产品兼容性考虑ioref左侧预留一个端口。 3.reset电路比2011版本有所改进。防止reset意外复位,reset电路更加稳定。 arduino mega简介: ...
Revision 3 of the Arduino Mega 2560 board (A000067) has the following new features: 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from...
Two pins 20 and 21 support I2C communication where 20 represents SDA (Serial Data Line mainly used for holding the data) and 21 represents SCL(Serial Clock Line mainly used for providing data synchronization between the devices) SPI SPI通信 ...
addresses from 0 to 7 are not used because are reserved so the first address that can be used is 8. Please note that a pull-up resistor is needed when connecting SDA/SCL pins. Please refer to the examples for more informations. MEGA 2560 board has pull-up resistors on pins 20 - 21 ...
TWI接口(20(SDA)和21(SCL)):支持通信接口(兼容I2C总线)。 3.AREF:模拟输入信号的参考电压。 4.Reset:信号为低时复位单片机芯片。 The MEGA 2560 is designed for more complex projects. With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch it is the recommended board for...
