Have around 100 MySensor nodes and this is the first time I get this error. #define F(string_literal) (FPSTR(PSTR(string_literal)))Ĭ:\Omat\Own_projects\Arduino\libraries\WS2812FX-master/WS2812FX.h:284:50: note: in expansion of macro 'F'Įrror compiling for board WeMos D1 R2 & mini. It replaces the macro template with the value of macro expansion. If at any point while M is disabled the preprocessor processes an instance of M (whether or not syntactically valid for expansion), it marks that particular M token as disabled. When the program run and if the C preprocessor sees an instance of a macro within the program code, it will do the macro expansion. To reduce hydrogel drift during microscope acquisition, PoliLlysine (Sigma) is applied on 24 mm round 1.5 coverglass for 30 min at 37 C. The per-macro disabling bit for a macro M is set during the the rescan phase whenever M is being expanded, and is cleared once expansion of M is complete. There are basically two pre-processor Macro Expansion directives: define and undef. Pre-processor processes the macros at compile time hence that macros replace with the corresponding code fragments. #define CORE_DEBUG(x.) hwDebugPrint(x, #_VA_ARGS_) //!(pstr_pointer))Ĭ:\Users\userxxx\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\2.3.0\cores\esp8266/WString.h:39:34: note: in expansion of macro 'PSTR' The values 10 and 20 are called macro expansions. Macros are the names of text/ literal values/ string (constant values) or code fragment, which will expand when pre-processor processes the macro. This is known as the expansion of macros. Macro Processor replaces each macro instruction with the corresponding group of source language statements. For example, if a macro is defined with the name PI and the expansion. #define PSTR(s) (_extension_())Ĭ:\Omat\Own_projects\Arduino\omat\libraries\MySensors/core/MySensorsCore.h:91:40: note: in definition of macro 'CORE_DEBUG' Macro represents a group of commonly used statements in the source programming language.
