This is a relay-switch + PIR sensor control application It is based on the general purpose http server for ESP8266 written in uPython
It is mainly a loop that control a PIR sensor and a relay for devices like ESP8266
-
the http server is general purpose and is easy to customize
-
the Makefile is pretty powerful and automatize upload and reset by means of espsend.py which should be installed or configured in the proper directory
Server can be called with: http://192.168.1.123:8805/help.txt
HTML files can be added/uploaded into FLASH memory of device and will be served.
For example if you upload your example.html file and request: http://192.168.1.123:8805/example.html
Can be configured in the main loop to serve dynamically generated contents Conventionally contents are kept in cb_xyz() in content.py
I use a configurator that reads and saves variables into json files
Server http is a class object with a main loop to serve requests. It is timeout
The parser of requests works only on first line that has the request from browser: GET /example/?var1=value1&var2=value2 HTTP/1.1
Contents are produced with embedded html commands
It uses BOOTSTRAP for css/js. I have made shortcuts url for the cdn repository:
https://goo.gl/EWKTqQ = https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js
http://goo.gl/E7UCvM = http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css
This is a little tricky and I developed the espsend.py to automatize the uploading and to have a very fast cycle of edit-deploy-run-test
I use the following tools to develop:
esp-open-sdk # git clone https://github.com/pfalcon/esp-open-sdk.git
micropython # git clone https://github.com/micropython/micropython.git
esptool # git clone https://github.com/themadinventor/esptool.git

Let's start with a bare ESP8266 device like WeMos.

Install latest version of micropython
make instruction
A number of tricks are used to keep memory allocation low.
