| I'm only doing usb_cdc_putc() and no printf, but I guess the stack could fill as well. I've never debugged the stack, how could I see the amount of stack used at a precise moment using the pickit3 deb ... | |

Forum: General CCS C Discussion Posted: Tue Jan 15, 2013 9:02 am Subject: Problem with PIC24FJ timers |
| So, by default, the setup_timer1() sets a 0xFF period and that's why the interrupts happens every 1.6s, isn't it?
In my application I need to change the interrupt frequency during execution, and tha ... |

| I changed the #use delay to:
#use delay(clock=20MHz, xtal=20MHz) and the blinking period changed to 1.6s. That is the exact period for when the timer goes from 0x0000 to 0xFFFF with the ... |
