I want to establish can communication on CAN1 in which message being transmitted ,after every 5 m,/s. Below is my main.c and mcu.c .

This is mcu.c file.

    Well, so what is the problem? and I don't see any CAN code in your main!

      Don't use the RMW form here

      TIM2->SR &= ~TIM_SR_UIF; // Clear the update interrupt flag

      Just write the mask, it's safer and lacks secondary effects

      TIM2->SR = ~TIM_SR_UIF; // Clear the update interrupt flag
