* Fix ambiguous for TwoWire::requestFrom() methods. * Remove TwoWire::begin(int) overload Inside the function, this overload truncated the data type to a shorter one. This could break some users' hopes. * Rewrite TwoWire with using HardwareI2C - implement proposal https://github.com/espressif/arduino-esp32/pull/8818#issuecomment-1792191815 to bring the HARDWARE interface into compliance * Fix TwoWire::end() return type. * Fix TwoWire::setClock() return type. * Fix no return statement in the TwoWire::requestFrom. * fix(libraries/Wire): fix bad return-statement Remove non-void values of the return-statements in function returning 'void'. * style(libraries/Wire): replace tabs with spaces * refactor(libraries/Wire): use slave without support TwoWire::begin(uint8_t address) should be available without slave support by SoC? * refactor(libraries/Wire): remove unused variables Compiler reports "Wire.cpp:393:15: error: variable 'err' set but not used [-Werror=unused-but-set-variable]". * refactor(libraries/Wire): remove unused variables Compiler reports "Wire.cpp:337:15: error: variable 'err' set but not used [-Werror=unused-but-set-variable]". * fix(libraries/Wire): hide slave support elements TwoWire::user_onRequest is used only in conjunction with slave support? * refactor(libraries/Wire): remove temporary comment * fix(libraries/Wire): restore an accidentally deleted implementation TwoWire::endTransmission() was accidentally deleted from a cpp file. * refactor(libraries/Wire): return return types In TwoWire class return return types. * fix(libraries/Wire): fix return type * refactor(libraries/Wire): add return statement if slave isn't supported Co-authored-by: Jan Procházka <90197375+P-R-O-C-H-Y@users.noreply.github.com> * refactor(libraries/Wire): fix indentation Co-authored-by: Jan Procházka <90197375+P-R-O-C-H-Y@users.noreply.github.com> * refactor(libraries/Wire): fix indentation Co-authored-by: Jan Procházka <90197375+P-R-O-C-H-Y@users.noreply.github.com> * refactor(libraries/Wire): fix indentation Co-authored-by: Jan Procházka <90197375+P-R-O-C-H-Y@users.noreply.github.com> * refactor(libraries/Wire): remove unnecessary empty lines --------- Co-authored-by: Lucas Saavedra Vaz <32426024+lucasssvaz@users.noreply.github.com> Co-authored-by: Jan Procházka <90197375+P-R-O-C-H-Y@users.noreply.github.com>
