微處理器 - Espressif ESP-WROOM-32 (NodeMCU ESP-WROOM-32) - Arduino - LED



參考資訊:
https://arduino.github.io/arduino-cli/0.31/installation/

步驟如下:
1. 連接板子到PC
2. 執行如下命令

$ cd
$ arduino-cli sketch new blink
$ vim blink/blink.ino
#define LED 2

void setup() {
    pinMode(LED, OUTPUT);
}
 
void loop() {
    digitalWrite(LED, HIGH);
    delay(1000);
    digitalWrite(LED, LOW);
    delay(1000);
}
$ $ arduino-cli compile --fqbn esp32:esp32:nodemcu-32s blink
$ arduino-cli board list
    Port         Protocol Type              Board Name FQBN Core
    /dev/ttyUSB0 serial   Serial Port (USB) Unknown

$ arduino-cli upload --port /dev/ttyUSB0 --fqbn esp32:esp32:nodemcu-32s blink
    esptool.py v4.6
    Serial port /dev/ttyUSB0
