Added ATTiny3224 and platformio init, builts, not tested #65

Closed ieb closed 2 years ago

ieb commented 2 years ago

This adds support to build the programmer for an ATTiny3224 using the same settings as the ATTiny 0 1 settings. The avrdude settings are copied and checked against the datasheet with the signatures. Have not changed or looked at the pin assignments yet. Have not built a board or tested for real, hence draft. Added platformio.ini for convenience.

Is there anything more you can see I would need to do to the code to make this work ?

(why am I thinking of using a ATTiny3224? they are currently available at pre-pandemic prices and are shipping)

avrdude.conf tested ok (Uno -> 3224), although a 3224 (14pins) sourced from Farnell (ie genuine) reports with the chip ID of a 3227 (24pins). Will prototype a pcb to see if a 3224 works as the programmer.

Works fine, but have decided not to build a programmer based on a Attiny3224.
