 # esp-stereo-api
 Using micropython on a esp8266 to create an api endpoint for controlling my stereo
+
+
+# Setup
+> Setup is done on MacOS 10.14.3
+
+### Flashing the chip with micropython
+We need to start by flashing micropython to our esp8266. Download micropython from [http://micropython.org/download#esp8266](http://micropython.org/download#esp8266).  
+Next we need to install esptool from espressif. This is a python-based, platform independent, utility to communicate with the ORM bootloader in the Espressif ESP8266 & ESP32 chips. There might be other great tools for flashing these chips out there aswell. Check out their [github page](https://github.com/espressif/esptool) for updated installation instructions.  
+
+Now we can flash our chip with the downloaded binary file. First find your esp chip:  
+`ls /dev/tty.usb*`
+
+I run esp8266 tool from the source files in a virtualenv, your command might veary slightly:  
+`env/bin/python3 esptool.py -p /dev/tty.usbserial-1460 write_flash -z 0x0000 ~/firmware-combined.bin`  
+
+Note the `tty.usbserial-1460` device name and the path `../firmware-combined.bin` for the micropython binary.
+
+
+### Install
+
+Requirements:
+ - ampy [https://github.com/pycampers/ampy](https://github.com/pycampers/ampy) / `pip install adafruit-ampy`
+
+Transfer boot script:  
+```
+$ ampy -p /dev/tty.usbserial-1460 put boot.py
+```
+
+Again note the `tty.usbeserial-1460` device name.
+
+### Configure
+
+Temperary requirement - set PSID and password for network to connect to. Fill in the empty strings `sta_if.connect('', '')` on line 44 in boot.py.
