arduino megaAVR Boards -- Report a bug.
by Arduino Version 1.8.6
for Arduino Uno WiFi Rev2, Arduino Nano Every.
Since these two types of boards only occur in Ver1.8.6, please report bugs and take countermeasures.
The content of the bug.
I want to control a character type LCD using LiquidCriystal.h, but with this board manager version, the following error occurs and compilation cannot be verified.
Also occurs in the Hello World for LCD, which comes with arduinoIDE.
Ver1.8.5 Nano Every selected == normal.
Using the library LiquidCrystal version 1.0.7 in the following folder:
D:\ Arduino1812\Arduino\libraries\LiquidCrystal
"D:\shiroto1214\AppData\Local\Arduino15\packages\arduino\tools\avr-gcc\7.3.0-atmel3.6.1-arduino5/bin/avr-size" -A "C:\Users\SHIROT~1\AppData\Local\Temp\arduino_build_203132/HelloWorld.ino.elf"
Of the maximum 49152 bytes of flash memory, sketches use 2162 bytes (4%).
Of the maximum 6144 bytes of RAM, global variables use 46 bytes (0%) and local variables can use 6098 bytes.
Ver1.8.6 Nano Every selected == Abnormal.
