Posted on June 15, 2017 at 09:17Hi,
I have been developping a HAL to configure and control the basic functions of the timers so I can configure an interrupt using timers 6 and 7.
The issue I am experimenting is that when I firstly initialize and enable the interrupts for the TIM6 I instantly have the first interrupt.
The way I am configuring the timer is :
1. Configure all the parameters (operation mode, period, ARR preload enable, etc)
2. Enable the TIM interrupt (UDIS and UIE)
3. Enable the counter (CEN = 1)
But I also tried to chage step 2 and 3 :
1. Configure all the parameters (operation mode, period, ARR preload enable, etc)
2. Enable the counter (CEN = 1)
3. Enable the TIM interrupt (UDIS and UIE)
I obtain the same strange behaviour.
Is this the correct way to configure for the first time?
After this first instantaneous interrupt it works fine during the next interrupts (I re-init the TIM6 inside a callback).
Thanks in advanced,
Omar
