OpiMc

Internet-radio player for Orange Pi Zero written in Python2.

Device use HD44780 display and sensor buttons to control it. Also, use build-in http server to handle request remotely via json-api, using https connection and basic http auth

Requirements

• ds18b20 sensor
• 16*2 HD44780 display with i2c adapter
• 4 click buttons and resistor
• configured spdif kernel module for audio output
• configured i2c and w1_therm, w1gpio, wire kernel modules

Feautures

• playing internet radio stations
• display time and date
• display temperature
• display cpu and mem load
• build-in python http-server to handle commands from remote

Dependencies

Python modules smbus, python-vlc, pyA20, pyyaml

Module pyA20 was wrote for Python version 2, so Python2 only

Preparations

• Add stream radio sources to stations.json file
• Change temp_sensor_file value in config.yaml file to your ds18b20 sensor w1 address
• Change lcd i2c address in devices/I2C_LCD_driver.py file from 0x3F to your address
• Generate ssl key for build-in http-server with command openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes and put server.pem file to certfile directory. Notice, that during of running openssl command, you should specify parameter common name as your device local ip address.
• Change server_user_name and server_user_password params to yours for base http authentication
