Hi, I have little problems with timers in LPC1768. I need to start timer2 because I use timer0 and timer1. When I want to configure and start timer2 all program doesn't start and I see nothing reaction - white display and no reaction. I have question: can I use more timers than 2? How many timers can I use ? And the second problem - I'd like to turn off one of the timers. How can I do it ? I understand that I must change pins on TCR register, but when I set bit 0 or 1 from documentation I turned off timer but I can't turn on again...I can turn off only once. I don't understand it.
LPC_TIM1->TCR |= 1 << 0; - start timer LPC_TIM1->TCR |= 0 << 0; - turn off timer ? It doesn't work...
I also tried LPC_TIM1->TCR |= 1 << 1 but then timer didn't start again when I set LPC_TIM1->TCR |= 1 << 0 again. I think that you understand what I mean. Thanks for help.
Not sure if you can.
But it can be done.
Have you enabled any interrupt routine for that timer? If you have, but isn't servicing the interrupt, you get into troubles.
OK, I've just done it. I have three timers - timer0 generate scuqare wave on pin MAT0.0 (P3.25) and play some melody, timer1 and timer2 draw snake and put random pixels. Now I have to make turning off the timers...I understand turning off is depend on bit in TCR and logical operations, but I read in documentation that, if I clear bit 1 or 2 for timer0 I won't do nothing - "Feature disabled." That while I have to change only one bit if I want to stop timer - I must disable interrupts. I think that...But I'm not sure.
