Title: $50 robot microcontroller exchange
Post by: Bubbles on January 27, 2008, 09:15:05 PM

can i change the circuit for the $50 robot to work with the atmega8515 without adding any extra hardware and just changing where i solder things in?

the pins arn't the same

yep if you look at the datasheets only the Atmega8 and Atmega 168 have the same pins.

he knows the pics wont be the same. he just doesnt want to add external hardware to make it work

you will have to re do the board so that the microcontroller can fit it's extra pins

All ATmegas are basically the same in how they operate, in terms of the user.

Of course the pinout will be different, and you will have to modify the source code a bit, but yea the hardware I have on the $50 Robot is the bare minimum you will need for any ATmega.

I didnt check the atmega8515 datasheet, but if you can find equivenlent pins on it, then the same hardware will work.
