The Serial2 pins were changed because psram is typically on 16 & 17. With a WROOM module, they are available. 👍 1 Collaborator SuGlider commented Apr 13, 2024 It was changed for 3.0.0 as a breaking change. But for 2.0.x it should reamain the same, not breaking previous sketches...
github上最新的git已经解决了该问题,使用git获取最新版,不要下载Release的 解决方法二: 去掉Serial2 serial_sevice.cpp中, 第40,41行 将MAX_SERIAL的值改为2.将41行中的Serial2去掉
ESP32 C3 MINI, UART Serial Not working with Echo Style Projectby Chhess » Sun Jul 21, 2024 7:24 am Hello there, I am completely new to this forum and ESP IDF and I am trying to understand the basics of IDF before I begin to work on a more sophisticated BLE project....
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...
I'm trying to use the second serial port on my new ESP32-C3-WROOM-02 board.The main port UART0 is OK and I bootload the program from Arduino IDE, and I receive debug informations.GPIO are working well to, I only need to send data from UART1 to finish my project !
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...
