一、GPIO 中断使用简析 1、中断触发方式 ESP32 Arduino 有以下四种触发方式: LOW 低电平触发 CHANGE 电平变化 RISING 上升沿触发 FALLING 下降沿触发 HIGH 高电平触发 2、配置中断 在定义中断函数后,需要在 setup 函数配置中断函数 // interrupt=中断通道编号,function=中断函数,mode=中断触发模式 ...
Many people are asking questions about how to use its GPIO pins. Which GPIO pin can be used as a digital input-output pin? Which GPIO pin can be used as an analog pin? And which pin should not be used to use this board safely? You will get the answer to these questions in this ...
Hi all, I'm working on a project using the ESP32-R3 with display and touch. The question is, what GPIO pins can I safely use? I can't find a pin out diagram of the board - can someone point me in the right direction? TIA -Andrew...

Why does the datasheet mention that using SPI pins as GPIO is not recommended instead of explicitly stating that you can't? Thanks again. Because technically, it's possible to add another SPI device in parallel with the flash, and you'd use those pins then. In practice, this has a ...
