API

• console.log(string)
• setTimeout(callback, ms) : int
• setInterval(callback, ms) : int
• clearTimeout(id)

esp32 module

• esp32.millis() : int
• esp32.digitalRead(pin) : int
• esp32.digitalWrite(pin, value) // value=0: LOW, 1: HIGH
• esp32.pinMode(pin, mode) // mode=1: INPUT, 2: OUTPUT
• esp32.setLoop(func) // func is called every arduino loop().
• esp32.deepSleep(us) // not returns

If WiFi.h is included:

• esp32.isWifiConnected() : bool
• esp32.fetch(url, {method:string, body:string}): Promise<{body:string, status:int}>
