Topic: ATmega328P  -  New from Atmel (Read 2 times) previous topic - next topic


it seems like that is the one thing left to do, only problem is im not sure what changes were made to iom328p. everything else is fine except for a strange bug in the TWI interrupt handler..

spiffed: please note that i made some corrections to the bootloader instructions...make sure the fuses and text is fixed because otherwise it will 'appear' to work at first but cause some serious problems later when a large program overwrites the bootloader :(

Is it possible to replace the 16 MHz crystal oscillator to a 20MHz for the Diecimila without any changes to the two caps?  This ATmega328P will be pretty cool.

Frank Katzenberger asked a great question! :)

Can we upgrade to a 20MHz oscillator crystal or 20MHz resonator and run the ATmegaXXX-20 chips at the spec'ed 20MHz and modify the bootloader and libraries accordingly to compensate ( so the timing is correct )?

You know the mega168 is also spec'ed to run at 20MHz...
It was only the Mega8 that was limited to 16Mhz.
