FW for ESP8266 used with 3D printer
|
|
|
|
##Description
|
|
Thanks to @disneysw for bringing this module idea
|
|
Thanks to @lkarlslund for suggestion about independant reset using GPIO2
|
|
|
|
Have a bridge configurable by web (implemented) and optionally by printer (not yet implemented)
|
|
Have a front end to know what is the wifi status (implemented) or know what is the print status (not yet implemented) - this part can be optional and removed by compilation directive if no need
|
|
|
|
Should be compatible with reprap printer (Marlin FW/Repetier FW)
|
|
|
|
##Hardware connection
|
|
--Use GPIO2 to ground to reset all settings in hard way - 2-6 sec after boot / not before!! Set GPIO2 to ground before boot change boot mode and go to special boot that do not reach FW. Currently boot take 10 sec - giving 8 seconds to connect GPIO2 to GND and do an hard recovery for settings
|
|
--Use GPIO0 to ground to be in update mode
|
|
--Use a switch to reset/disable module

##Development
|
|
Currently using [Arduino IDE 1.6.5](http://arduino.cc/en/Main/Software) with the esp8266 module from board manager added from [github.com/esp8266/Arduino](https://github.com/esp8266/Arduino)
|
|
using relased version (http://arduino.esp8266.com/package_esp8266com_index.json)
|
|
and staging version (http://arduino.esp8266.com/staging/package_esp8266com_index.json)
|
|
|
|
Additionnaly:
|
|
--Use minimal css from http://getbootstrap.com/examples/theme/ if connected to internet, this is to get better UI and rendering according display device (link can be changed in FW), if not available ,CSS is ignored displaying basic HTML
|
|
|
|
##Flash the Module
|
|
*Tools:
|
|
--Use IDE to upload directly (latest version of board manager module generate one binary)
|
|
|
|
*Connection
|
|
--Connect GPIO0 to ground to be in update mode
|
|
|
|
##Web configuration
|
|
*Wifi Mode : Access point / Client station
|
|
*IP Generation: DHCP/Static IP
|
|
*IP/MASK/GATEWAY for static data
|
|
*Baud Rate for serial (supported : 9600, 19200, 38400, 57600, 115200, 230400)
|
|
*web port and data port
|
|
|
|
|
|

##Commands from/to serial(not yet implemented):
|
|
*from module to printer [Need Printer FW support and can be disabled in ESP FW]
|
|
-M800 S1 , restart module done need a wifi/activity restart
|
|
-M801 [Message], Error message from module
|
|
-M802 [Message], Status message from module
|
|
-M804 [AP/STATION,SSID,DHC/STATIC,IP,MASK,GW,STATUS,MAC ADDRESSS, BAUD?], ]Module configuration without password
|
|
|
|
*from host to printer (not yet implemented) [Need Printer FW support] on port 8888
|
|
-M803 [IP, AP,SSID, Password....], ]Module configuration settings to be used by module
|
|
-M805 query to get M804 informations
|
|
|
|
|
|
|
|
*from printer to module [Need Printer FW support and can be disabled in ESP FW] (not yet implemented)
|
|
-request configuration/status (generate the M804 as answer)
|
|
-set AP/STATION,SSID,PASSSWORD,DHC/STATIC,IP,MASK,GW,BAUD from serial
|
|
|
|
##Front End (basic implemented) [need Printer FW support it] or just display module status
|
|
--Display printer status
|
|
--Display temperatures (done)
|
|
--Display positions/flow/speed (done)
|
|
--Display print progress if any
|
|
--List SDCard Content
|
|
--Launch/Stop/(Pause?) a Print
|
|
|
|
##TODO
|
|
-- Define Front End Functions
|
|
-- do testing
|
|
-- do a complete drawing for connections
|
|
-- add some Javascript to enhance web UI
|
|
|
|
|
|
more to come
