原因:由乐鑫官方的技术规格书可知,Serial1默认使用GPIO9、10,而ESP32的GPIO6~11一般用于连接外部Flash芯片也就是ESP32储存程序的地方 导致程序崩溃。 解决方法:ESP32片上功能模组所发出的信号可映射到任何GPIO引脚,使用HardwareSerial.h库便可将串口RX映射到几乎所有IO口上, TX映射到GPIO0~13上(可能)。 使用Hardwa...

Refer to this ESP32 devkit board pinout. (if it’s not clear, right-click and open it in a new tab for a larger view) ESP32 PWM Channels The ESP32 PWM controller is primarily designed to control the intensity of LEDs, although it can be used to generate PWM signals for other purpose...
Refer to this ESP32 devkit board pinout. (if it’s not clear, right-click and open it in a new tab for a larger view) ESP32 Interrupt Trigger Edge (Events) There are 5 different events to trigger an interrupt for each external interrupt pin. You can programmatically choose the event at...
It has always worked for me on "AVR ISP" although I'm unsure if it actually uses that over something else built in to the ESP32 board manager. Also make sure you put the ESP32 in programming mode when the Arduino IDE attempts to upload: Hold down "boot" button, and momentarily press...
Now to run this example of LED blinking using ESP32, simply copy this code to Arduino IDE and compile the code. After compiling code, click on the upload button to upload the code to the ESP32 devkit. Before uploading the code, make sure you have selected the board and COM pin to whi...
Re: Attempting to interface ESP32-S3-DevKitC-1 with Arduino IDE v2.2.1 PostbySprite»Mon Jan 15, 2024 8:35 am Can you try forcing the board into download mode before attempting to upload? You do that by holding the BOOT button and then momentarily pressing the RESET button before rele...
