Motorized Slider based on ESP8266 an Micropython
Installation
Slider and all dependencies should be build as frozen modules (beacuse of memory that use, bytcode is lighter for ESP), instruction how to make it you can find here: https://learn.adafruit.com/micropython-basics-loading-modules/frozen-modules
Generally you have to build your own firmware based with followed frozen bytes:
uhttpd
uasyncio
logging.py
console.sink.py
copy
types
I reccomend to download micropython-lib repository and symlinks all necessary libs into modules folder.
In few steps: Start Vagrant
set symlinks for slider modules:
cd ~/micropython/ports/esp8266
ln -s /vagrant/slider modules/slider
ln -s /vagrant/slider_api.py modules/slider_api.py
ln -s /vagrant/uhttpd/ modules/uhttpd
ln -s /vagrant/uasyncio/ modules/uasyncio
ln -s /vagrant/logging.py modules/logging.py
ln -s /vagrant/console_sink.py modules/console_sink.py
copy
typesmake all staff copy main.py into ESP and reboot
Wiring & Configuration
All wiring setup is described in config.py, you can also change some of predefined values.
Default OLED display is active, but if you want to disable it, please just set False for display_active variable.
Connection
After installation ESP create WiFi network, you can connect to it and use any browser and use host http://192.168.4.1
to open web-based interface which allows you to move a dolly in specified direction and setup timelapse modes.
