Add support for the entire tinyAVR-2 family

[MCUdude]

Support for the entire tinyAVR-2 series is currently missing. This PR solved this.

Closes #25
Closes platformio/platform-atmelavr#268
Closes platformio/platform-atmelavr#263

Awesome, thanks!

[MCUdude]

@valeros you're welcome!

BTW the latest avrdude.conf file lacks support for the entire tinyAVR-2 family and the AVR-DDs.
Would be great if you could fix this!

You can find the missing board definitions for the entire tinyAVR-2 and AVR-DD lineup here in the official avrdude.conf file:

Could you please point me what MCU are missing exactly?

[MCUdude]

Could you please point me what MCU are missing exactly?

Sure! Please add these to Avrdude.conf

tinyAVR-2:

• ATtiny424, ATtiny824, ATtiny1624, ATtiny3224
• ATtiny426, ATtiny826, ATtiny1626, ATtiny3226
• ATtiny427, ATtiny827, ATtiny1627, ATtiny3227

AVR-DD:

• AVR16DD14, AVR16DD20, AVR16DD28, AVR16DD32
• AVR32DD14, AVR32DD20, AVR32DD28, AVR32DD32
• AVR64DD14, AVR64DD20, AVR64DD28, AVR64DD32

But really, it isn't necessary to have a separate Avrdude version just for atmelmegaavr targets. Avrdude supports both.

[valeros]

Thanks, the avrdude packages have been updated to support the latest TinyAVR and AVR-DD targets.

[MCUdude]

Thank you!

Hi,

i tried to build an empty project in platformio for the attiny1624.
I get the error message, that the TCD0 timer for millis dont exist.
According to datasheet ther is no TCD timer available, only TCA and TCB.
After changing the flags to TCB, i can build succesfully, but i dont know witch timer is the correct one for millis.

"extra_flags": "-DARDUINO_attinyxy4 -DMILLIS_USE_TIMERB0 -DUARTBAUD5V",

@marco-117 I've just submitted PR #39 that uses timer TCB1 for millis() instead. This is the default megaTinyCore timer for the tinyAVR-2 series chips.
