Hi all,Trying to make the serial communication between L3GD20 gyroscope and STM32F3 an software interrupt based one, the code written for it in ''demo'' is based on polling,suggest me a procedure to modify it.

The STM32 parts function in very similar manners, would suggest you go look for some example code dealing with SPI and IRQs, and leverage that with your coding skills.

Sir,we have modified the existing code(in main.c & stm32f3_discovery_l3gdc) and created a new IRQ handler ,the modified part we have attached to this post.We are unable to debug this part of code,Please notify us where the fault exists.Thanking you sir.
