Re: ESP32-S3-WROOM-1 preferred PINs for I2C and CANby Sprite » Tue Sep 14, 2021 1:08 am You can; it's OK to use input-only pins for input-only functionality. (Thanks for pointing that out, it slipped my mind that CAN has a RX pin before the transceiver.)...

常用的像是Wroom-32系列模块该脚内部已下拉,即flash是工作于3.3V的,若外部电路接强上拉则可能导致模块工作异常。 外部中断 外部中断使用方式如下: 使用attachInterrupt(uint8_t pin, void (*)(void), int mode)或attachInterruptArg(uint8_t pin, void (*)(void*), void * arg, int mode)来设置外部中断,...
This routine can use the ESP32-S3-GEEK's IIC hardware interface to drive I2C modules. The routine uses the BME680 sensor for demonstration, printing data via the serial port. It is suitable for learning how the ESP32-S3 interacts with the BME68X sensor, allowing you to set pins and com...
