Title: atmega168 or 328
Post by: blackbeard on October 19, 2010, 12:39:35 PM

so i was originally going to make my led cube using an atmega 168 with the arduino bootloader but someone has told me that it is somehow not as fast. i find this hard to believe since my understanding is that it's a drop in replacement for the 328 and the only difference is the amount of memory to store your program. i don't have many atmega328 ics and they're also more expensive so i'd like to not use them if it's possible. for a project such as a single color led cube would it be necessary to use an atmega328 over a 168? will there be any real discernible difference?

There is a difference i.e(Double Flash 16KB to 32KB, Double SRAM 1KB to 2KB, and Double EEPROM 512 Bytes to 1KB.
But in the project you are describing I personally think that you not find "Any real discernible difference". :P
