1 # Serial RGB LED driver, Interplay Medium™ dendrite module (for ESP8266)
3 This is IM denrite module (remote wifi network device) created for [Interplay Medium™](https://interplaymedium.org) project.

9 For LEDs be sure to add MOSFETs and current limiting resistors appropriately. Wiring scheme will be added probably later.

14 ## Bidirectional MOSFET level shifter
16 To drive an addressable RGB strip along with ESP8266, you need to synchronize logical levels.
17 I usually use a simple MOSFET solution for single-channel shifting, hovever for multi-channel management, I would recommend using a simple Logic Gate IC like 74HC08 or a level shifter such as TXB0104.

21 ## Preparing the building environment
23 Make sure that you have the environment installed as described at
25 1. [makeEspArduino.mk](https://github.com/plerup/makeEspArduino.git)
26 2. [esp8266 Arduino SDK](https://github.com/esp8266/Arduino)
28 3. In the *make* script, change path for each variable approprately:
32 ## Change your IM AXOD microserver or AP (router) WIFI login and password
37 assign SSID and PASSWORD of your local IM AXOD microserver or Access Point in there
40 WIFI_PASS="ssid password"
42 You can change it later whenewer you want using HTTP interface
46 initial buildong and flashing firmware at once
48 ./make Serial_RGB upload
50 after that you may just build the binary and uload it using remote HTTP interface
53 curl -F image=@Serial_RGB.bin -s im_<....>.lan/update
58 By default dendrite can be reached "im_serial_[last 4 digits of MAC address]" doman
62 curl "im_serial_[last 4 digits of MAC address]?rename=NEWNAME"
64 Turn on the color and effect
66 curl "im_serial_[last 4 digits of MAC address]?gradient=ffffffccff44&slidez=-1&delay=100"
70 curl "im_serial_[last 4 digits of MAC address]/help"
74 The development of this firmware is in progress. Here is a brief list of upcoming changes:
76 * features (save, reset....)
77 * state return in 2 variants
82 dimm and soft state changing
83 rgbwdef -- save default values in EEPROM, which is returning on reset command
85 * switching AP/slave, AP by defuault
86 remote access setup (host name, AP/slave, SSID, passw)
