在arduino-esp32代码中，定义了Serial、Serial1、Serial2三个对象，并指定了相应的引脚。其中，Serial的TX为GPIO1，RX为GPIO3；Serial1的TX为GPIO10，RX为GPIO9；Serial2的TX为GPIO17，RX为GPIO16。需要注意的是，ESP32芯片默认配置下，6-12GPIO用于FLASH接口，无法被其他程序使用。因此，Serial1默认无...
Re: ESP32-C3 supermini serial port problem Postbylbernstone»Tue Apr 16, 2024 4:48 am What version of arduino-esp32 are you running (you can see this in the board manager)? There were some issues with earlier versions of esptool on the C3, but if you are running 2.0.15, that ...

在代码(github.com/espressif/ar) 中可以看到 arduino-esp32 中定义了 Serial,Serial1,Serial2 三个对象,并且指定了对应的引脚, Serial 的 TX 是 GPIO1, RX 是 GPIO 3, Serial1 的 TX 是 GPIO10,RX 是 GPIO9 , Serial2 的 TX 是 GPIO17, RX 是 GPIO 16。 在 ESP32 芯片默认配置情况下 6-12 GP...
HardwareSerial库是c++编写的,应用于esp32 Arduino应用环境的串口驱动库,我们在安装好ESP32的Arduino开发环境后就已经集成了这个串口操作库,在实际应用时直接引用就可以了。 注意:ESP32共有3个UART端口, 其中UART1用于Flash读/写,我们使用串口1时需要注意,需要将串口1映射到其他GPIO上即可,我测试了一下GPIO12、GPIO...
When working with ESP32 WiFi/Bluetooth MCU under Arduino SDK for ESP32, you will notice that Serial work just fine. But Serial1 and Serial2 do not. ESP32 has 3 hardware serial ports that can be mapped to almost any pin. But, Serial1 and Serial2 will not
In this tutorial we will check how to detect the client disconnection event when using the Bluetooth Serial library of the Arduino core, running on the ESP32. In this previous tutorial we have already covered how to configure a callback function to handle the Bluetooth Serial Port Profile (SPP...

I am wanting to implement a Uart in a ESP32 Arduino project using platformIO. The problem is that I want to use a timeout to detect end of received packet but the “uart.h” library in PlatformIO does not support “uart_event.timeout_flag”. My code is below. Can you point to diff...
