ESP32 has 8 pulse counter (PCNT) modules which are used to count the number of positive or negative edges of the signal given to the GPIO pins. Each pulse counter module consists of a 16-bits counter register which counts from 0 to 65536 on the positive or negative edge of an input si...
The ESP32 development board features a built-in hall effect sensor that detects changes in the magnetic field in its surroundings. This tutorial shows how to use the ESP32 hall effect sensor with Arduino IDE and MicroPython. ThehallRead() function has been discontinued. Reading the hall sensor ...
对于任何一款芯片,GPIO接口是其最基本的组成部分,也是一款芯片入门的最基本操作,下面论述下 关于esp32开发版的GPIO操作,本文中重点讲解下关于如何创建eclipse工程,并通过eclipse下载到esp32中去(本文的工程文件在esp-idf/example/periheral文件夹中gpio工程),这里就不再详细论述了,可以看前面的文章,本文重点讲解工程源码...

ESP32开发环境搭建 - VScodeESP32开发环境搭建VScode下载及设置安装PlatformIO IDE创建工程编译及烧录API及例程ESP32开发环境搭建本文采用VScode作为开发IDE,使用ESPIDF作为开发的库,开发时资料比较好查,不像Arduino库,很多函数不好找资料。毕竟IDF开发是官方提供的库函数,资料相对还是好找的,IDF库函数链接:https://docs....
Requires Arduino ESP32 Core 3.0 or higher Incompatible with ESP32-C2 and ESP32-C3, as they don't have PCNT units. Most Basic Example #include <RotaryEncoderPCNT.h> RotaryEncoderPCNT encoder(25, 12); void setup() { Serial.begin(115200); } void loop(){ Serial.println(encoder.position(...
There are 4 independentPCNTunits on an esp32-s3. There is not an arduino wrapper for pcnt, but the IDF functions will work if you just include the appropriate headers. Check out the"best frequency meter ever" Vlelectroniclab Posts:2 ...
esp32的 arduino或者vscode pio 有没有脉冲计数pcnt的库函数 不是靠中断计数那种 是硬件资源 嗯好哟哈 11-16 0 ESP32C3super mini识别不到pn532 南极帝企... 有没大佬知道原因。 南极帝企... 11-15 2 新手求助啊 (wow) 大佬可以解释下为什么这串代码烧录后只有白屏? 共4 张 MCU起航 11-...
