port.c configuration for ATmega1284P

Posted by Paulo Flabiano Smorigo on June 8, 2011
Hi everyone,

I need to set the port.c configuration for ATmega1284P. I'm currently using the follow one:
#define portCLEAR_COUNTER_ON_MATCH     ( 1<#define portPRESCALE_1024                    ( (1<#define portPRESCALE_256                     ( 1<#define portPRESCALE_64                      ( (1<#define portCLOCK_PRESCALER                  ( 64 )
#define portCOMPARE_MATCH_A_INTERRUPT_ENABLE ( 1<#define TIMSK TIMSK1

Show I use TIMSK0 or TIMSK2 instead? And the portCOMPARE_MATCH_A_INTERRUPT_ENABLE is correct?

Thanks in advance!
Paulo

I don't think that is an official port, and the configuration items are definitely not present in any port I have looked at before. These seem to be register bit value settings so you are best looking in the hardware manual or datasheet for the device for the correct settings. Or ask whoever wrote the port, I'm pretty sure it is not in the official code base.
