To put the chip into programming mode, you have to pull GPIO0 low during startup. If your ESP8266 board doesn't have a reset button, you could add one by connecting a push button to between the RST pin and Make sure you don't have anything connected to GPIO2 (more information in the next chapter).Prevent random resets by connecting the RST (reset) pin to V CC through a 10KО© resistor.Select normal boot mode by connecting GPIO0 to V CC through a 10KО© resistor.an ESP-01), it is already connected to ground internally, so you don't have to worry about it. If your module doesn't have a GPIO15 (e.g. Disable SD-card boot by connecting GPIO15 to ground through a 10KО© resistor.Enable the chip by connecting the CH_PD (Chip Power Down, sometimes labeled CH_EN or chip enable) pin to V CC through.If you're using a bare-bone ESP-# board by AI Thinker, you have to add some resistors to turn on the ESP8266, and to select Void setup ( ) Hardware connections Enabling the chip The easiest way is to just upload an empty sketch to the Arduino beforehand (see File > Examples >

Main microcontroller, so we'll have to make sure that the Arduino is not using the Serial connection while we're flashing It cannot be disconnected from the Arduino's

To flash the ESP8266, we'll use the USB-to-Serial converter of the Arduino. If you don't have such a converter, it is possible to use the internal USB-to-Serial converter of an Arduino to flash Wemos D1 mini or NodeMCU).ДЄlternatively, you could use a bare-bones AI-Thinker module, and program it using a USB-to-Serial converter. The best way to flash an ESP8266 is by using an ESP8266 development board (e.g. Home get_app feedback Flashing the ESP8266 with an Arduino UNO Pieter P
