I would like to know which timer MIOS_TIMER function uses... I'm trying to make a guitar tuner (or a frequency meter), but I can't get it work properly (I need a 16bit counter...)

I get C source code from here

http://www.myplace.nu/avr/gtuner/gtuner.c

and my code should be ok... but not timer things...

thanks!

Hi Pilo,

MIOS_Timer uses TMR3, thats already a 16 bit timer, and by using the MIOS_Timer_Init function you're able to control "allowed" parameters.

Take care that USER_Timer is an interrupt service routine (Use FSR2, use IRQ_TMP*, etc...)

Best Regards, Thorsten.

mmm sounds good ;)

actually I don't need the interupt, or maybe just in case the input frequency is too low. I just need to get and set the 16bits counter value.

thanks! ;)

Hi Pilo,

the problem is, that you didn't mention which problems you are observing, therefore I cannot really give you an useful answer...

However, the lcd_benchmark application demonstrates how to use TMR3 w/o interrupts.

Best Regards, Thorsten.
