Blink_using_Timer0 does not work with Atmega8: OCR0 not available #54

Closed shaffenmeister closed 6 years ago

shaffenmeister commented 6 years ago

Observation: Compilation of Blink_using_Timer0.ino fails for Atmega8.

Error message:

/home/cappel/.arduino15/packages/MiniCore/hardware/avr/2.0.1/libraries/AVR_examples/examples/Blink_using_Timer0/Blink_using_Timer0.ino: In function 'int main()':
Blink_using_Timer0:29: error: 'OCR0' was not declared in this scope
     OCR0 = 0x00;  // Output compare
     ^
exit status 1
'OCR0' was not declared in this scope

Possible reason: OCR0 ist not available in Atmega8(L), according to Atmel data sheet.

Software environment: Arduino 1.8.5 MiniCore 2.0.1 BSP: Arduino AVR core 1.6.207 Xubuntu 18.04, Windows 10

can confirm I checked the data sheet. It looks like the Atmega8 doesn't have that register.

Thanks for the reminder, I totally forgot to look at it. It correct that ATmega8 doesn't have that register.
