Hey @JColvin, Yes your are correct. I just want to detect low -> high transitions. Which parameter to change in software to get the edge check polarity right? Connect through faster means denoted communication between people other than forum. Regards Shyam S

Hey @jpeyron, Thanks for the files you had shared. I have a simple doubt. Through this I was able to design. My requirement is that slave device required to be connected to the FPGA generates interrupt and the signal goes high and remains stable till the device is acknowledged. But when device is acknowledged with use of your program it is again going to interrupt service routine because the signal goes from high to low. I want to make sure that interrupt is serviced only when the rising edge is detected. I am using Axi GPIO with Axi Interrupt controller as in the above design. Also with your design i tried button and led glow. When pressing button there is interrupt generated and when button is released another interrupt. I had checked the debounce condition as well. It is proper. Any idea to help me out such that interrupt gets called only when the button is pressed and not released? It would be helpful if we can connect through faster means as well. Thanks and Regards

Thanks @jpeyron In the helloworld.c inside main function i can see a loop which reads from GPIO and outputs it. I am not able to comprehend where does interrupt in GPIO comes to play. It will be helpful if u explain Shyam S

Hi @jpeyron Can you share the 2018.2 version of the code as well. If possible can you attach the bd file as pdf or image so that we could view it. Thanks Shyam S
