我在ESP32-C3-WROOM-02上将GPIO18和GPIO19端口配置成输入下拉,外部也做了下拉处理,读取这两个IO的状态,GPIO18是低电平,而GPIO19却是高电平??而在ESP32-WROOM-32E上同样的配置,读取出来都是低电平。 #define GPIO_INPUT_1 18 #define GPIO_INPUT_2 19 #define GPIO_INPUT_PIN_SEL ((1<<GPIO_INPUT_1)...
然后将剩余GPIO做了简单测试。 根据SoftwareSerial库,esp23c3的有效pin如下:return (pin >= 0 && pin <= 1) || (pin >= 3 && pin <= 7) || (pin >= 18 && pin <= 21); 共九个,每个软串口用2pin,故建4个软串口也就是极限了。 测试程序: 1#include <SoftwareSerial.h>2SoftwareSerial uart...
ESP32 C3 gpio 18 19 usb pins Postbyskeiron09»Mon Nov 15, 2021 6:09 am I want to use 18 and 19 pins as normal gpio digital output pins to control LED but cannot get desired output maybe due to it is configured as usb + and usb - pins. pin 18 is at 0V all the time and ...
把GPIO口依序填入 ps[ ] 并执行测试。 ps = [2,3,10,6,7,11,5,4,8,9,0,1,12,13,18,19] #ESP32-C3 CH343 ,20,21 保存+ 执行 GPIOtest_ESP32-C3_CH343.py SHELL窗口报错,无法使用,例如正在通信的 CH343-GPIO20/21 1 2 3 4
I've connected my ESP32C3's GPIO18 and GPIO19 to the USB connector in the hopes that I can directly communicate with it over USB. I am not sure what the next step is. Do I need special drivers? What are the use cases for this? Can I use those pins/USB for uploading programs, ...

16.esp_sleep_enable_gpio_wakeup(); 17./*Enter sleep mode*/ 18.esp_light_sleep_start(); 19./*Execution continues here after wakeup*/ 在没有配置唤醒源的情况下也可以进入 Light-sleep 模式,在这种情况下,ESP32-C3 将一直处于Light-sleep 模式,直到外部复位为止。
MicroPython REPL 位于 UART0(GPIO1=TX,GPIO3=RX)上,波特率为 115200。Tab-completion 用于查找对象的方法。粘贴模式 (ctrl-E) 可以将一大段 Python 代码粘贴到 REPL 中。 machine模块: import machine machine.freq() # 获取CPU频率 machine.freq(240000000) # 将CPU频率设置为240 MHz ...
