使用UART通信模式,需要两部分RX-TX, TX-RX的连接 两个arduino实现通信,一个uno,一个mega,uno端连接lcd1602,显示通信类容 mega的程序如下: String device_mega = ""; String device_uno = ""; void setup() { // put your setup code here, to run once: Serial.begin(9600); Serial1.begin(9600); ...
设置串口,使用uart_driver_install函数进行 install: 参数分别为:串口号,接收缓冲区,发送缓冲区,队列长度(消息长度),中断回调函数(没有写NULL),中断标志位。 在示例中使用: 完成前面3步就完成了UART的基本配置,接下来就可以进行收发了, 使用uart write bytes()往Tx FIFO buffer里面写数据,就可以发送数据; 使用uar...
Serial1 使用UART1,TX引脚为GPIO2。UART1不能用来接收数据因为通常情况RX引脚被用到flash芯片连接了。使用Serail1,调用 Serial1.begin(baudrate)。如果Serial1没有使用且Serial没有被调换 - 通过在Serial.begin之后调用Serial.set_tx(2)或者直接调用Serial.begin(baud,config,mode,2) 可以将UART0的TX映射到GPIO2...
[Get Code] 在setup()里打开连接到计算机的串口和Linux void setup() { Serial.begin(115200); Serial1.begin(linuxBaud); } [Get Code] 在loop()里,从一个串口连接复制数据到其他串口。如果有"~"字符通过,进入命令模式。 void loop() { // copy from virtual serial line to uart and vice versa ...

Example code for combined servo output and sensor input using two UART ports This example is for the MEGA 2560 and ESP32 boards and will display servo debug information on the screen. No actual code to control a servo control is included in this example (screen display only). ...
examples accounts for that sort of, but it expects that the WiFi gadget is connected on the 2ndhardware serial port,Serial1whereas on our board, it will beSerial3. I'll show you below. First, the following is what you can expect to find at the beginning of any of the example code. ...
