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 ...
GPIO35 GPIO36 (VP) GPIO39 (VN) Check this tutorial:How to use push button with ESP32 Note: The maximum operating current which GPIO pins can sink and source is 40mA according to the datasheet of ESP32 chip. But it is recommended to keep it below 20mA. ...
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...
pins (GPIO34, GPIO35, GPIO36, GPIO37, GPIO38, GPIO39) can only serve as digital input pins. Nonetheless, the 24 pins available for digital output are sufficient to power LED, relay,seven-segment displays,liquid crystal display, and other actuators. Therefore, any of the thirty pins can ...
SPIHD (GPIO12) and SPIWP (GPIO13) Pins are available to use as GPIO? In the Pin Layout section (2.1) of the datasheet, Pins 19 and 20 (SPIHD and SPIWP) of the ESP32C3-FH4 are labeled as NC (Not Connected). However, in the table in section 2.3, they are designated as defau...
