SMARS

SMARS is a simple 3D printed robot designed for the educational field. This is the acronym of “Screwless/Screwed Modular Robotic System”.

This is how it is supposed to look like

And this is how it looks in my case :-)

SMARS, WeMos, and NodeMCU

Brief NodeMCU HOWTO

NodeMCU project provides an excellent documentation, so no need to go into much details here. In brief, do the following steps to build and flash firmware image to WeMos D1 mini board:

• Get firmware source code

$ git clone https://github.com/nodemcu/nodemcu-firmware.git

• Customize NodeMCU firmware image Enable the following options in app/include/user_modules.h:

#define LUA_USE_MODULES_BIT
#define LUA_USE_MODULES_FILE
#define LUA_USE_MODULES_GPIO
#define LUA_USE_MODULES_GPIO_PULSE
#define LUA_USE_MODULES_MQTT
#define LUA_USE_MODULES_NET
#define LUA_USE_MODULES_NODE
#define LUA_USE_MODULES_PWM
#define LUA_USE_MODULES_SJSON
#define LUA_USE_MODULES_TMR
#define LUA_USE_MODULES_UART
#define LUA_USE_MODULES_WEBSOCKET
#define LUA_USE_MODULES_WIFI

• Build firmware Build NodeMCU firmware:

$ make

• Flash firmware Flash NodeMCU firmware to WeMos D1 mini board:

$ sudo ./tools/toolchains/esptool.py --port /dev/ttyUSB0 write_flash -fm dio -fs 32m 0x00000 bin/0x00000.bin 0x10000 bin/0x10000.bin
