🧑🏻‍🔧 Hardware Setup

-Cable USB type C for power and upload code.
-Power 5-24VDC.
There's really no need because we used 5V power via type C cable.
Both type C cable and power supply via terminal can be connected at the same time.
-Cable ethernet, Use for ethernet demos.

🧑🏼‍💻 Software Setup

+Install IDE arduino. Follow this, skip if you done.

⚠️ WARNING: Install in Document folder.

+Install driver CH340. Follow this, skip if you done.
+Install ESP32 in manager board:

• Down load this folder: hardware
• Extract at ...\Documents\Arduino. Ex my computer: C:\Users\NamPC\Documents\Arduino
• Go to ...\Documents\Arduino\hardware\espressif\esp32\tools
• Click get and gen:
  

• Check it in IDE:
  

At here , you are ready 👌 to execute the sample code for the ESP32_CANOPUS board

⚠️ WARNING: Prepare yourself a cup of coffee ☕☕☕, because the next is a fascinating journey with Canopus board 🤪.

You will be stronger after working through the next 12 examples.

#define LED_YELLOW 2 //Pin led color yellow is IO2
void setup() {
  // initialize digital pin LED_YELLOW as an output.
  pinMode(LED_YELLOW, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_YELLOW, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_YELLOW, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
