I am using DE2-115, my problem is when I use Pixel buffer to draw anything on the screen it works but it also draws small strange dots with different colors, I tried to clear the buffers but they still appear.
Thanks in advance
The slave IP is an option to assign an IP as a slave IP in Qsys. This helps to clear any invalid transactions that might cause a glitch in the system.
You can simply add a PIO IP into your Qsys design and then assign this IP as a default slave as shown in the image below.
