Скачать или смотреть AXI GPIO & Memory-mapped I/O (MMIO) : read/write to peripherals using a C pointer & control user I/O

Learn how to master AXI GPIO and memory mapped I/O on Zynq UltraScale+ devices in this tutorial!
This video walks you through creating a complete hardware-software project that demonstrates how to control peripherals from ARM cores using memory-mapped I/O. The Vitis application read the DIP switch in polling mode and controls the LED shift pattern.

In Part 1, you'll learn how to:
Set up a Vivado block design with Zynq UltraScale+ IP
Configure multiple AXI GPIO blocks for LED control and DIP switch input
Implement a 32-bit adder in programmable logic that its ports connected to AXI GPIOs
Review the "Address Editor" in Vivado, and compare it with "Addressing View" option in block design
Generate and export hardware for Vitis

Part 2 covers the software implementation in Vitis, where you'll discover:
How to use memory-mapped I/O with C pointers to access peripherals
Working with Xil_Out32 and Xil_In32 functions for reading/writing to hardware
Creating an interactive LED pattern controlled by DIP switches
Understanding memory addressing and hardware abstraction
