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 thi
gpio_config_tio_conf = {};// 禁用中断io_conf.intr_type = GPIO_INTR_DISABLE;// 设置为输出模式io_conf.mode = GPIO_MODE_OUTPUT;// 要设置的引脚的位掩码,例如GPIO18/19io_conf.pin_bit_mask = GPIO_OUTPUT_PIN_SEL;// 禁用下拉模式io_conf.pull_down_en =0;// 禁用上拉模式io_conf.pull_u...

GPIO脚配置 //#define TFT_RST -1 // Set TFT_RST to -1 if the display RESET is connected to NodeMCU RST or 3.3V// ### EDIT THE PIN NUMBERS IN THE LINES FOLLOWING TO SUIT YOUR ESP32 SETUP ###// For ESP32 Dev board (only tested with ILI9341 display)// The hardware SPI can b...
Here is an example code in C/C++ that controls a motor, connected to GPIO5 of the ESP32, via PWM. const int motorPin = 5; // Example GPIO pin for motor control void setup() { pinMode(motorPin, OUTPUT); } void loop() { // Vary the motor speed using PWM for (int dutyCycle ...
这里选择烧毁JTAG_SEL_ENABLE, 将 GPIO10 连接至 GND 引脚。在配置 ESP-IDF 环境后, 在对应终端输入以下命令: espefuse.py burn_efuse JTAG_SEL_ENABLE 1. 然后你会得到一个需要输入BURN的确认信息,如下: Connecting... Detecting chip type... ESP32-C3 esp...
一般来说通过 Iot.Device.Ws28xx.Esp32 库,我们即可方便的驱动自己的 LED。根据板子的资料我们可以查到 ESP32-S3-Zero 板载了一颗 WS2812B LED,这颗 LED 的引脚是 GPIO 21,我们可以通过以下代码来驱动这颗 LED: intWS2812_Count =1;intWS2812_Pin =21;varleddev =newWs2812b(WS2812_Pin, WS2812_Coun...
任意GPIO均可作为PWM脚, 编号与GPIO一致, 但同时只能开启4路PWM,务必注意 板载按钮控制板载LED 代码功能,按下板载按钮boot切换左右LED亮灯显示 highlighter- Arduino #include<Arduino.h>constintboard_btn =9;constintboard_led_left =12;constintboard_led_right =13;voidsetup(){Serial.begin(9600);pinMode(bo...
ESPlane-FC-V1 使用 ESP-Drone 新版本代码,需要对硬件进行改动,即使用跳线,将模组 GPIO14 连接到 mpu6050 int 管脚。 ESPlane-FC-V1 防止上电时 IO12 触发 flash 电压切换,使用espefuse.py将 flash 电压固定到 3.3 V:espefuse.py--port/dev/ttyUSB0set_flash_voltage3.3Vnote*Onlythefirstdeviceattaching...
< GPIO pin for camera SCL line (legacy name) */ }; 12345678 然后把 pin_sccb_sda 的赋值,修改为-1,修改成-1 后,摄像头的配置,会使用前面已经初始化的 I2C 口(第 2 小节给出了这个原因)。 然后,在 pin_sscb_scl 赋值的下一条语句,加一条 sccb_i2c_port 的配置,赋值为 0。 接着,往下找到 ...
