pilo Posted February 2, 2004 Report Posted February 2, 2004 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 herehttp://www.myplace.nu/avr/gtuner/gtuner.cand my code should be ok... but not timer things...thanks!
TK. Posted February 4, 2004 Report Posted February 4, 2004 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.
pilo Posted February 5, 2004 Author Report Posted February 5, 2004 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! ;)
TK. Posted February 5, 2004 Report Posted February 5, 2004 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.
