If you want to program your ESP32 and ESP8266 with MicroPython firmware, it’s very handy to use an IDE. In this guide, we’ll introduce you to Thonny IDE. After completing this guide, you’ll have your first LED blinking using MicroPython and Thonny IDE. We’ve experimented with severa...
熄灭颜色 - LED 熄灭时的颜色。默认为黑色。n (int or None) –Number of times to blink; None (the default) means forever. 次数- 闪烁的次数;None(默认)代表一直闪烁。 background (bool) –If True (the default), start a background thread to continue blinking and return immediately. If False...
