Hello everybody !!On my program I want to have a signal of 400 Khz with my timer2 in PWM mode and have the RTC for the clock, on. RTC work without the Timer2, Timer2 work without RTC, but when I try to have them at the same time it doesn't work and the systick too. I try all the possibilities of the priority. I tried to do like the demo program of the STM32F10B because there is RTC, systick and TimeR2 together. I tried on TIMER3, the same. And today, still doesn't work. I think I have try everything...Maybe someone had the same problem.... :-[ :-[ :-[ :-[ :-[ .......

I will accept help from anybody.

Thanks a lot !

Hy Hervett,

I using STM32F103RE with ST320F10x-E Eval board, RTC and Timer1 togher without problems:

-Timer 1 from HSE 8Mhz-> 48MHz with pwm function at 20KHz frequency

-RTC from LSE 32KHz for wakeup during stop mode

The systick is set at 32ms.

It's OK now, My program work with my TIMER2 in PWM, my RTC and the Systick, but still don't work wth my Timer2in Output compare toggle mode. So I will keep the PWM for my 400 kHz.

I havn't do something special, it is just the difference between PWM ans Output compare toggle mode.

Bye
