code changes from uno to attiny85 for 3d printer issues

Projects Programming
1

how do peeps, need some help. last year as part of my redundancy my old boss gave me a 3d printer/ scanner combo, great huh? he must really like me, although its an xyz davinci 1.0 aio, im not looking a gift horse in the mouth, its helped me do lots of really useful (unless you ask my wife about it) stuff. the issue is that they put a chip in the bottom of their filament carts that makes sure you can only use their filament, some time ago a guy named in the sketch below decided he had had enough of that and developed the attached sketch to reset the chip, it works great, although not for 400m of filament which means when you buy it by the kilo it needs resetting twice for each spool, anyway thats not the problem, ive been using an official uno to do all the resetting but im now using that for another project, it would suit my needs better to be using an attiny85 (which i have a handful of already) so that it can be stored inside the machine out of the way and only powered when i need to reset the cart. but im getting this error

am i asking too much of the tiny fella or is there something else im missing here? any help would as usual be much appreciated.

They're doing direct port manipulation to write the pins, instead of digitalWrite(). That's fine, but it means that you need to adjust the register names to match the pins on the Tiny85.

The ATTiny85 doesn't have a port D, so the registers that relate to that port don't exist. Hence the compile errors. It's only got a port B (so the registers are things like PORTB and DDRB - AVR ports have up to 8 pins, so there's no need for more than one port on the t85). Look up a guide to direct port manipulation for the background you'll need on controlling pins like that.

Did you mean to include some context around that block of code?

Does it work? Does it not work?

5

is is the code for the chip read/reprogram, it works with the uno but i need some hand holding to work out (be shown) what to do to get it working with the attiny85.

DrAzzy:
They're doing direct port manipulation

thanks for the reply, im in over my head already, i really need help with what i need to change and what to change it to, this really isnt my strong point, im more the type of person who needs physical items to understand whats really going on, all this code an pseudo code is witch craft to me!
