RX & TX pins are not coupled with the internal USB, what are they used for? RX & TX are still connected to UART0, and still used with the USB when in CDC (download mode). Otherwise, you can use them as UART0 when connecting a module that uses serial, or use them as general IO...
In the first few lines of the code, we include the required libraries such as Arduino.h, U8x8lib.h, and Wire.h. The U8x8lib.h library provides functions to control the OLED display, and the Wire.h library provides functions for I2C communication....
The noise gathered by the ADC of the pins with a LRD was unrealistic. For this reason, I ordered a few different I2C sensors to solve the noise problem. I then tried to make a simple sketch in the Arduino IDE to display some text on an LCD1602, just to communicate via I2C, but I ...
此时电脑就会显示有USB设备接入。使用arduino或者espidf选择好下载方式进行程序的编译烧录即可 成功之后,会在串口监视器中得到调试信息,代表复刻成功。如果显示i2c通信不正常,检查单片机与电源模块的接线方式等等 使用注意事项 有问题请先仔细阅读文档,若未解决,群中问之,详述原因,必答之 ...
I2C interface: The ESP32-S3 provides multi-channel hardware I2C, currently using GPIO6 (SDA) and GPIO7 (SCL) pins for the I2C bus. The QMI8658 six-axis inertial measurement unit and LCD touch control chip are mounted on the board. For details, please refer toSchematic ...
