Timer Issue Arduino Uno WiFi Rev2

Hello Everyone!

I have a timer error: warning: ‘TIMER1_OVF_vect’ appears to be a misspelled signal handler missing’__vector’ prefix [-Wmispelled-isr] ISR(TIMER1_OVF_vect)

I searched in Arduino.h 27:0 and that references avr/interrupt.h and I am racking my head on finding anything thats misspelled or is that even it? attached is my Timer.cpp as it references to line 42.the board I am using is the Uno WiFi Rev2 4809 board. Thanks in advanced for the help!

Arduino.h (5.52 KB)

Timer.cpp (1019 Bytes)

It's based on Atmega4809 so the interrupt vectors are named differently
