* Reimplement SD.h write methods exactly in File Replace the individual override with the existing SD.h File's implementation for all methods of File::write. Fixes #5846 * Add add'l tests * Fix Print and File incompatible writes w/casts Print and File have ambiguous resolutions for single-argument write(0)s. Fix by adding explicit methods. A write of any integer will not be a const char* write (i.e. won't write a string) but will instead just write the integer truncated to 8 bits (as makes sense). * Use 256byte chunks in ::write template Reduce stack requirements for templated writes to 256bytes, matching the size uses in WiFiClient/etc. (from 512bytes). Reduces the chance of stack overflow. * Move write(int) methods up to Print.h Remove some technical debt by moving the ::write(int/short/long) methods out of FS and HardwareSerial and up into Print.h.
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 trivialy 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 intersepting 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 (same as IDE's tools 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) 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 (preferred): 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 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) - optionaly 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.
