* uart fixes and BW improvements * uart: read_char straightly use hw buffer * +attributes for functions called by ISR * uart: BW improvements read_char straightly use hw buffer (+ ~10%bw) read by block (+ ~190%bw) (instead of generic Stream::readBytes) attributes for functions called by ISR remove overrun message remove some ISR flags which were not honoured * fix merge * fix buffer overflow * serial stress test sketch * astyle * serial stress example: interactive keyboard, stop reading, overrun * serial device test: bandwidth & overrun * update + HardwareSerial::hasError() * interactive overrun in example * astyle * Test using @plerup's SoftwareSerial as submodule (tag 3.4.1) * update upstream ref (fix warning) * host mock uart/read(buf,size) * reset style changes in submodules before style diff * update build_boards_manager_package.sh for submodules * trigger CI (removing space) * cannot reproduce locally the CI issue, setting bash -x option to get live trace * remove previously added (in this PR) 'set -e' in package builder (passes local tests, not real CI) script-comment new recipe.hooks.core.prebuild.3 (along with already commented .1 and .2) moved CI package test to be first on the test list remove 'set -x', wish me luck
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. 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) -f no throttle (possibly 100%CPU) 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.
