Minor Bugfixing, Enhanced MCU and Transmitters compatibility, updated…

[rtu-dataframe]

Hi @Zwer2k,

I've created a PR in order to these following enhancements at project level:

• Renamed ISR to _ISR as reserved name for ATMEGA Boards
• Added ICACHE_RAM_ATTR check for ESP8266 and ESP32 Boards
• Tested on Arduino Duemilanove and ESP32 ESP-WROOM-32
• Added more details to docstring and README.MD into example file
• Optimized code for Arduino ATMega based MCU
• Changed extension to example file to .ino

Hallo @Simonefardella ,

Thank you for your support. I get an error message when I run "platformio test": Warning! Ignore unknown configuration option 'src_filter' in section [platformio] .pio\build\esp12e\libFrameworkArduino.a(core_esp8266_main.cpp.o):(.text._ZL12loop_wrapperv+0x4): undefined reference to 'setup' .pio\build\esp12e\libFrameworkArduino.a(core_esp8266_main.cpp.o):(.text._ZL12loop_wrapperv+0x8): undefined reference to 'loop' .pio\build\esp12e\libFrameworkArduino.a(core_esp8266_main.cpp.o): In function 'loop_wrapper()': core_esp8266_main.cpp:(.text._ZL12loop_wrapperv+0x21): undefined reference to 'setup' core_esp8266_main.cpp:(.text._ZL12loop_wrapperv+0x2d): undefined reference to 'loop' collect2.exe: error: ld returned 1 exit status *** [.pio\build\esp12e\firmware.elf] Error 1

With WeatherStationDemo.cpp it worked. How can I test the code?

Ok, i've restored the original .cpp file extension, i don't know why, but it seems that platformio needs the .cpp files in order to run the unit tests.

As matter of fact, now everything works!
