esp-httpd
Background
Web-server for Espressif ESP8266/EX chips. Sprite started the project and billprozac continued, adding OTA functionality and few more things.
I re-wrote the whole project, fixed and added few more other things.
Firmware features
- Web server
- Multiple connections
- CGI routines
- HTML tokens replacement
- Filesystem support
- Compression support (Heatshrink)
- OTA
- Documentation and code-readability
Changelog
For changelog from billprozac's version look at changelog.md.
Main esphttpd development by Sprite is available at Sprite's git.
Sample project
- web-server available at 192.168.4.1
- GPIOs are reset to state 0 on initialization
- index.tpl displays a sample switch which changes its state on-click, and keeps its state on server-side
- the switch on index.tpl controls both GPIOs' states
- WiFi settings enable switching between modes as usual
Setup
Step-by-step guide is available here.
In short, follow the instructions on esp-open-sdk, then customize makefile parameters to match for your own environment:
- XTENSA_TOOLS_ROOT
- SDK_EXTRA_INCLUDES
- SDK_EXTRA_LIBS
- SDK_ROOT
- SDK_VERSION
Git
- git clone https://github.com/izhak2/esphttpd
- cd esphttpd
- git submodule init
- git submodule update
Note: I recommend to change manually lib\heatshrink\heatshrink_config.h to use:
- #define HEATSHRINK_MALLOC(SZ) os_malloc(SZ)
- #define HEATSHRINK_FREE(P, SZ) os_free(P)
just in case to prevent compiling errors.
Compiling
Have a look at config.h and set your own settings, then compile as usual. For example, to compile an OTA version:
make clean
make rawflash OTA=true
Development
Main project is available at Sprite's git. I decided to share my work in case someone will find it useful for his own needs. I'll be updating it sometimes; if you'd like some features to be added or meet any bugs, feel free to contact me.
