Make sure that the jumper between GND and GPIO0 is there so that the board is in reflash mode. If it still doesn't work, check your connections.

If the MAC addresses don't appear within a few seconds, disconnect the power to the board and reconnect it. Uncheck the box for the 0x10000 IROM section.Д¬lick on Flash(E) to start the programming process. Select the 0x7C000 default and 0x7E000 blank sections. Later, you canДownload the latest firmware, then select the tab and choose the new. This is unlikely to be the latest version, but to get started quickly, use the default internal image. The flasher program comes with default NodeMCU firmware in memory.

If you have more than one, select the correct one from the drop down menu. If you only have one COM device, the port will appear automatically. The adapter will appear as a new COM port on your system.

Users of XP or older versions of Windows may need a driver which should be supplied by the manufacturer of the USB adapter.

#Software serial esp8266 programming windows 7

Most adapters are automatically recognized by Windows 7 and 8. Plug the USB to serial adapter into your PC.

Connect GPI0 to GND to enable flash reprogramming.

Connect Vcc to CH_PD to enable the chip.

The actual connections will depend on the board you have and the USB to serial adapter you are using. Then right click on View Raw and Save Link As. It is open source on github.ДЄnd choose Win32 or Win64 depending on your computer system. The tool you will use to flash the NodeMCU firmware on your ESP8266 board is the If you are not familiar with Lua, you will find that it is not hard to learn, at least for the simple tasks needed to get started. I recommend the NodeMCU Lua firmware as a starting point because it gives you an interactive programming language which allows you to experiment and build simple working programs without a lot of effort. Many come with AT firmware for serial communications.

The ESP8266 board you bought may have one of many different firmware versions on it.

When you receive your adapter, verify that the actual voltage output is 3.3 volts as some cheap adapters have been found to be mislabelled. The NodeMCU Development Board has the USB to serial interface on the board. It is possible to level convert if you already have a 5 volt adapter. This should be a 3.3 volt compatible model. The NodeMCU Development Board has a USB to 3.3V power supply on the board.ДЄ USB to serial adapter. A weak or poor quality supply will cause the board to reset unexpectedly and make debugging difficult. Maximum current draw is 300 mA, so use a supply that can supply 500 mA to be safe. Most of us use aДЈ.3 volt regulated power source. The ESP8266 runs on anything from 2.8 to 3.5 volts, so a couple of AA batteries will work. Have become available with additional sensors, relays, LEDs and voltage regulators on the board.ДЄ 3 volt power supply. The ESP-12 is popular because of its size and the number of pins brought to the side of the board. The ESP-01 is a simple board to start with. The prices vary from around $2 for a simple ESP-01 to $15 for a complete board with USB to serial and 3.3 volt regulator. Check the pins of the actual board you order with the information from your source as the rapid development of these products has led to confusion and duplication of board identification numbers. There are several ESP8266 boards available, usually numbered ESP-01 through ESP-12. You will need an ESP8266 development board. Not counting waiting for hardware to ship to you (1-10 days), you should be able to use your ESP8266 for something useful in less than an hour. This guide is for Windows users who want to use the NodeMCU environment. This page is meant to be a quick introduction to the ESP8266 for those who are confused by all of the information available on the various blogs and forums who just want to try out this exciting board in the shortest possible time.
