Data Firmware

First look at the WeMos D1 Arduino compatible ESP8266 Wifi Board from Banggood com

This video take a look at the WeMos D1: a Wi-Fi enabled Arduino compatible board based on the ESP8266 chip. The price of it is so tempting, less than 9$.


The board looks like an ordinary Arduino board. The dimensions and the pin layouts are exactly the same. So, this board is compatible with all the existing shields for Arduino. But don’t expect them to work at once, since the libraries available for the ESP8266 chip are few so far. The board, instead of an ATMEGA chip that standard Arduino boards use, use the impressive ESP8266 WiFi chip!

The ESP8266EX chip that the WeMos D1 board uses offers:
• A 32 bit RISC CPU running at 80MHz
• 64Kb of instruction RAM and 96Kb of data RAM
• 4MB flash memory! Yes that’s correct, 4MB!
• Wi-Fi
• 16 GPIO pins
• I2C,SPI
• I2S
• 1 ADC

First run NodeMCU and flash firmware

The below videos show first run NodeMCU in Windows 10, download and flash update firmware.

This video show how to find the NodeMCU connected port, and connect it with PuTTY.


Most probably, NodeMCU ship WITHOUT update firmware. This video show how to download and flash firmware on NodeMCU. To download firmware and flasher, visit https://github.com/nodemcu, and follow the steps shown in the video.
(May be you have to press and hold the on-board FLASH button, then click the Flash button of ESP8266Flasher, once flash started, you can release on-board FLASH button.)


If everything OK, you should able to connect NodeMCU with PuTTY, and enter Lua shell.
(If NodeMCU have no response in PuTTY terminal, try to press the RST button on NodeMCU.)




Next:
- Test NodeMCU onboard LED in Lua shell
