把你设备的RX pin和TX pin连接到你Mega开发板的TX1和RX1,如原理图所示。 image.png 示例代码: 确保你的Mega开发板通过USB连接到你的电脑,启动串口通讯。 voidsetup(){// initialize both serial ports:Serial.begin(9600);Serial1.begin(9600);}voidloop(){// read from port 1, send to port 0:if(Seri...
1. 把Arduino Mega安装到小车上,通过螺丝孔。 2. 把AFMotor扩展板安装到Arduino Mega卡上,脚位对准,不会安装请先学习上面链接的太极创客的教程 3. 把四个电机线接到M1,M2,M3,M4接口上 4. 安装电池(两节18650串联)接到EX_PWR端子上,注意正负极。 5. 连接蓝牙模块HC05 到Arduino Mega的14,15脚上(串口3的...
Serial 3:15 (RX) and 14 (TX) * Also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip. External Interrupts:Pins 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2...
图4:HC-05蓝牙模块和Arduino Mega的接线图 图5:将HC-05蓝牙模块连接到Arduino Mega 该模块由Arduino供电。HC-05的TX引脚直接连接到Arduino上的RX1引脚。但是,因为HC-05的逻辑电平为3.3V,而Arduino在5V下运行,所以HC-05的RX引脚上必须有一个简易分压器来降低电压。R1的值应为1 kΩ,R2的值可以为1.8 kΩ或2....
// If ESP8266-01 is being used, connect the RX to Pin 10 and TX to Pin 11 of Arduino UNO or MEGA (Or use other TX/RX PINS) void ESP826601::Init(SoftwareSerial &mySerial) { mySerial.begin(9600); } // ESP8266 Connect WiFi ...
- Not all pins on the Mega and Mega 2560 support change interrupts, so only the following can be used for RX: 10, 11, 12, 13, 14, 15, 50, 51, 52, 53, A8 (62), A9 (63), A10 (64), A11 (65), A12 (66), A13 (67), A14 (68), A15 (69). ...
The RX and TX LEDs on the board will flash when data is being transmitted via the ATmega8U2/ATmega16U2 chip and USB connection to the computer (but not for serial communication on pins 0 and 1). A SoftwareSerial library allows for serial communication on any of the Mega 2560's ...
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, ...
Just about all electronics use a UART serial port with RX and TX pins for debugging, bootloading, programming, serial output, etc. But it's rare for a computer to have a serial port anymore. Thus, a serial cable is an essential part of any electrical engineer's toolkit. This is a USB...
Disconnect the ISP programmer, and connect a USB to serial adapter to the target microcontroller shown in thepinout diagram. Select the correct serial port under theToolsmenu, and click theUploadbutton. If you're getting a timeout error, it may be because the RX and TX pins are swapped, ...
