Description
Wire.h in ArduinoCore-megaavr for Arduino Nano Every misses signatures which are used in the ArduinoCore
in megaavr core
size_t requestFrom(uint8_t, **size_t**); size_t requestFrom(uint8_t, **size_t**, bool); size_t requestFrom(int, int); size_t requestFrom(int, int, int);in the Arduino Core
fromhttps://github.com/arduino/ArduinoCore-avr/blob/master/libraries/Wire/src/Wire.h
uint8_t requestFrom(uint8_t, uint8_t); uint8_t requestFrom(uint8_t, uint8_t, uint8_t); uint8_t requestFrom(uint8_t, uint8_t, uint32_t, uint8_t, uint8_t); uint8_t requestFrom(int, int); uint8_t requestFrom(int, int, int);this miss match can throw warnings in libraries using the interface according to the the Arduino-Core - which i consider as "standard" how to do...
example
#include <Wire.h>void foo(){ uint8_t address = 1; Wire.requestFrom(address, (uint8_t)1);}void setup() { Wire.begin();}void loop() {}brings
