Interrupts from timer1 and timer2

Projects Programming
1

Hi. In my project, I use two interrupts. One from timer1 (library TimerOne) for working with the infrared remote control, the other from timer2 (library MsTimer2) for reversing the DC motor. Individually, each interrupt works fine, but together there is only the Timer1 interrupt works. I am new, but I suspect that Timer1 prohibits interruption from Timer2.
I will be grateful for any hint.

Since you are not a new member, you should know we need to see ALL your code in code tags, any error logs or other serial output also in code tags, and a wiring diagram (a photo of hand drawn is fine)
I am fairly sure I know what the problem is but will wait until you post what is asked.

no, it runs independently

I suspect that is not the case at all.

But until you put in the effort to show your sketch, properly formatted with the <CODE/> tool, I'm not going to put any more effort into speculation.

This is a sketch at the moment. IR remote is working, LEDs are flashing. So Timer1 is fine. But the motor does not turn on, although the command is accepted from the remote control, I checked it. So Timer2 does not generate an interrupt.

How have you worked around the fact that this library already uses one of the timers that you are attempting to reuse?

I read that remote uses timer1

Really.

And did you alter the IRremote library to actually make that happen? Because when I look in the library, this is what I see.

// Macros for enabling timers for development
//#define SEND_PWM_BY_TIMER
//#define IR_USE_AVR_TIMER1
//#define IR_USE_AVR_TIMER2
.
.
.
// Arduino Duemilanove, Diecimila, LilyPad, Mini, Fio, Nano, etc
#if defined(__AVR_ATmega328P__) || defined(__AVR_ATmega328PB__) || defined(__AVR_ATmega168__) \
    || defined(__AVR_ATmega88P__) || defined(__AVR_ATmega88PB__)
#  if !defined(IR_USE_AVR_TIMER1) && !defined(IR_USE_AVR_TIMER2)
//#define IR_USE_AVR_TIMER1   // send pin = pin 9
#define IR_USE_AVR_TIMER2     // send pin = pin 3
#  endif

Or are you not using a 328P based board? That's something you didn't see fit to mention.

Thank you. I got it. So remote uses timer1 and timer2. I will think. Thanks again.

Sigh. No, that's not what I wrote. That's not what the code snippet above says. That's not what the library's README says. I give up.
