This commit adds W5500 W5100 and ENC28j60 drivers from @njh with credits They are available in libraries/ An example is added in W5500 examples directory plus: * Extract dhcp server from lwip2 and add it to the core as a class. It must always be present, it is linked and can be called by fw on boot. So it cannot be stored in a library. * ethernet: static or dhcp works * PPPServer: example * bring WiFi.config() to the lwIP generic interface (argument reorder common function) * move hostname() from WiFI-STA to generic interface * remove non readable characters from dhcp-server comments * dhcp-server: magic_cookie is part of bootp rfc * fixes from https://github.com/d-a-v/W5500lwIP/issues/17 * enable lwip_hook_dhcp_parse_option() * +ethernet tcp client example in w5500 library examples
Host Tests for Continuous Integration
-------------------------------------
make FORCE32=0 OPTZ=-O0 CI
(FORCE32=0: https://bugs.launchpad.net/ubuntu/+source/valgrind/+bug/948004)
Sketch emulation on host
------------------------
This environment let compile esp8266/Arduino sketches into native
environment. Network (tcp, udp, including ssl and multicast) is linked to
local host interfaces. WiFi is trivially emulated and reported as "just"
already connected and usable.
Currently network emulation is a complete rewrite of
WiFiClient+WiFiServer/ClientContext and WifiUdp/UdpContext using socket
posix API. Further work will optionally propose native lwIP library
instead.
Serial UART0 and UART1 are emulated via stdin/stdout/stderr. Therefor
stdin is connected to UART0(RX) and stdout is connected to UART0(TX).
UART1(TX) writes to stderr. Reading from stdin happens in non-blocking
raw mode, that means each character is directly injected into the UART
FIFO without any buffering in the console. The command line switch -c
can be used to stop the emulation from intercepting CTRL-C (SIGINT).
How to compile and run a sketch
-------------------------------
All results are stored in ./bin/ .
Show the core example list:
make list
Build one example
make D=1 ../../libraries/esp8266/examples/Blink/Blink
run it:
./bin/Blink/Blink -h
Optional 'V=1' enables makefile verbosity
Optional 'D=1' enables core debug messages (same as Arduino IDE's tools/debug menu)
Optional 'OPTZ=-O2' will update gcc -O option (default is -Os, -D=1 implies -O0)
Optional 'FORCE32=0' will use native/default gcc (default is FORCE32=1 unless gcc-multilib is not detected)
Optional 'R="<options>"' (ex: R="-b -v") runs the executable with given options after build
Non exhaustive list of working examples:
make D=1 ../../libraries/ESP8266WiFi/examples/udp/udp
make D=1 ../../libraries/ESP8266WiFi/examples/WiFiClient/WiFiClient
make D=1 ../../libraries/ESP8266WebServer/examples/HelloServer/HelloServer
make D=1 ../../libraries/ESP8266WebServer/examples/AdvancedWebServer/AdvancedWebServer
make D=1 ../../libraries/ESP8266mDNS/examples/mDNS_Web_Server/mDNS_Web_Server
make D=1 ../../libraries/ESP8266WiFi/examples/BearSSL_Validation/BearSSL_Validation
Compile other sketches:
- library paths are specified using ULIBDIRS variable, separated by ':'
- call 'make path-to-the-sketch-file' to build (without its '.ino' extension):
- CAVEAT: functions must be declared *before* being called (arduino builder is not around)
make D=1 ULIBDIRS=/path/to/your/arduino/libraries/lib1:/path/to/another/place/lib2 /path/to/your/sketchdir/sketch/sketch
or:
ULIBDIRS=/path/to/your/arduino/libraries/lib1:/path/to/another/place/lib2 make D=1 /path/to/your/sketchdir/sketch/sketch
or:
export ULIBDIRS=/path/to/your/arduino/libraries/lib1:/path/to/another/place/lib2
export D=1
export OPTZ=-O2
make clean
make /path/to/your/sketchdir/sketch/sketch
./bin/sketch/sketch
Additional flags:
make USERCFLAGS="-I some/where -I some/where/else" \
USERCSOURCES="some/where/file1.c some/where/file2.c ..." \
USERCXXSOURCES="some/where/file3.cpp some/where/file4.cpp ..." \
USERLDFLAGS="-L some/where/around" \
...
Executable location is always in bin/. Once a sketch is compiled, just run it:
bin/sketch/sketch
Options are available:
-h
-i eth0 bind servers to this interface (WIP)
-l bind Multicast to the above interface (WIP)
-c ignore CTRL-C (send it over serial device)
-f no throttle (possibly 100%CPU)
-S spiffs size in KBytes (default: 1024)
(negative value will force mismatched size)
TODO
----
A lot.
Make fun, propose PRs.
- replace some "fprintf(stderr" with redirectable log functions
- spiffs in a file (done, need to initialize and check)
- EEPROM in a file (partly done)
- SDCARD on Host filesystem ? or in an image ?
- nice curses interface to display/change gpios ?
- display device emulation (like ssd1306)
- optionally use arduino-builder ?
- store sketch objects and binaries outside from the source directories (done for sketches)
- compile and use lwIP on host
- easily debug HTTP classes
- https://github.com/esp8266/Arduino/issues/1715
- gpio, currently:
read as 0(digital) or 512(analog).
output is printed on console.
