LED灯的负极连接ESP32-C3开发板的 GND 针脚; 最后使用 USB 线将ESP32-C3开发板连接到 PC。 最好LED灯连接一个220欧的电阻,避免电流过大烧坏了开发板针脚和LED,这里就不加了。 创建项目 首先,打开 VS Code 从模板项目创建 Blink 项目,按F1或选择顶部菜单【查看/命令面板(Ctrl + Shift + P)】,在命令行中...
蓝牙串口可以用无线的方式工作,非常有利于采集卡与pc的分离工作。默认使得板载的led同步闪烁,以指示电路板的工作。 #include<Arduino.h>#include"BluetoothSerial.h"BluetoothSerialbt;intrgb[]={0,2,4};voidsetup(){// put your setup code here, to run once:for(autopin:rgb){pinMode(pin,OUTPUT);}bt....

My question is this: I have six of these great 30-pin mcu's and the blue LED's all behave differently. For instance, some mcu's will light these blue LED's when there is absolutely NO code reference to GPIO2. If I set - Code: Select all digitalWrite (blu_led, LOW) in setup(...
bool LED = (bool)gpio_get_level(LED_GPIO); gpio_set_level(LED_GPIO, !LED); //gpio_set_level(LED_GPIO, ~LED); 目前还没有解决,如果有懂哥看到的话希望能够指导一下,谢谢! 2. 编译成功但是程序无法下载进去 解决方案:电机vscode左下方的清除,然后再下载即可 ESP32+显示屏硬件电路 这部分知识简单...
