how to program ATMEGA48PA-AU??

[stormrazer121]

So long story short ive a bait boat that has a faulty IC, ive been able to narrow it down to this however in my great wisdom of replacing the faulty ATMEGA48PA-AU i failed to realise something..


i cannot program it

How would one go forward to learn how to do this??

You get something like this.

And the adaptor that fits the AT device you want to program.

The software is free, and there really is little or no learning curve involved. its all just built in.


I have the older version of this, it just connects to a laptop/PC with a USB cable.
It has the added advantage of having a built in CMOS (40xxx) and TTL (74xxx) series logic tester.

But do you have a firmware to program to begin with?

[Audiorepair]

Ah, I forgot about that bit.

Thats the main issue i guess is that i do not have any firmware for it little lost on this one!

Either you read it from the old one (unlikely to succeed if it's damaged or code-protected, although there are companies in the East who can break the latter for a few k$) or write it yourself.

you can use something like this to do the programming:
https://www.ebay.com/itm/404348353863 ("USBASP USBISP AVR Programmer Adapter")
that costs just a few dollars on ebay.

then use an open-source program called avrdude:

however, as others have pointed out, getting hold of the binary data to program into the device going to be the problem.

NeoProgrammer can do it using an inexpensive CH341A.
